Highlights of GAO-10-446, a report to congressional requesters. 

Why GAO Did This Study: 

Billions of pounds of cargo are transported on U.S. passenger flights 
annually. The Department of Homeland Security’s (DHS) Transportation 
Security Administration (TSA) is the primary federal agency 
responsible for securing the air cargo system. The 9/11 Commission Act 
of 2007 mandated DHS to establish a system to screen 100 percent of 
cargo flown on passenger aircraft by August 2010. As requested, GAO 
reviewed TSA’s progress in meeting the act’s screening mandate, and 
any related challenges it faces for both domestic (cargo transported 
within and from the United States) and inbound cargo (cargo bound for 
the United States). GAO reviewed TSA’s policies and procedures, 
interviewed TSA officials and air cargo industry stakeholders, and 
conducted site visits at five U.S. airports, selected based on size, 
among other factors. 

What GAO Found: 

TSA has made progress in meeting the air cargo screening mandate as it 
applies to domestic cargo, but faces challenges in doing so that 
highlight the need for a contingency plan. TSA has, for example, 
increased required domestic cargo screening levels from 50 percent in 
February 2009 to 75 percent in May 2010, increased the amount of cargo 
subject to screening by eliminating many domestic screening 
exemptions, created a voluntary program to allow screening to take 
place at various points in the air cargo supply chain, conducted 
outreach to familiarize industry stakeholders with screening 
requirements, and tested air cargo screening technologies. However, 
TSA faces several challenges in developing and implementing a system 
to screen 100 percent of domestic air cargo, and it is questionable, 
based on reported screening rates, whether 100 percent of such cargo 
will be screened by August 2010 without impeding the flow of commerce. 
For example, shipper participation in the voluntary screening program 
has been lower than targeted by TSA. In addition, TSA has not 
completed a staffing study to determine the number of inspectors 
needed to oversee the screening program. Because it is unclear how 
many industry stakeholders will join the program, TSA could benefit 
from establishing milestones to complete a staffing study to help 
ensure that it has the resources it needs under different scenarios. 
Moreover, TSA faces technology challenges that could affect its 
ability to meet the screening mandate. Among these, there is no 
technology approved by TSA to screen large pallets or containers of 
cargo, which suggests the need for alternative approaches to screening 
such cargo. TSA also does not verify the self-reported data submitted 
by screening participants. Several of these challenges suggest the 
need for a contingency plan, in case the agency’s current initiatives 
are not successful in meeting the mandate without impeding the flow of 
commerce. However, TSA has not developed such a plan. Addressing these 
issues could better position TSA to meet the mandate. 

TSA has made some progress in meeting the screening mandate as it 
applies to inbound cargo by taking steps to increase the percentage of 
screened inbound cargo—including working to understand the screening 
standards of other nations and coordinating with them to mutually 
strengthen their respective security efforts. Nevertheless, challenges 
remain and TSA does not expect to achieve 100 percent screening of 
inbound air cargo by the mandated August 2010 deadline. TSA officials 
estimate that air carriers are meeting the current mandated screening 
level of 50 percent of inbound cargo based on estimates rather than on 
actual data as required by law. Thus, TSA cannot verify if mandated 
screening levels are being met. In addition, the agency has not 
determined how it will eventually meet the screening mandate as it 
applies to inbound cargo; developing such a plan could better position 
TSA to assess its progress toward meeting the mandate. 

What GAO Recommends: 

GAO recommends that TSA establish milestones for a staffing study, 
verify the accuracy of all reported screening data, develop a 
contingency plan for screening domestic cargo, and develop plans for 
meeting the mandate as it applies to inbound cargo. TSA partially 
concurred with verifying screening data and did not concur with 
developing a contingency plan because it did not believe such actions 
were feasible. GAO believes these recommendations remain valid, as 
discussed in this report. TSA agreed with all other recommendations.

The Honorable Bennie G. Thompson: 
Chairman: 
Committee on Homeland Security: 
House of Representatives: 

The Honorable John D. Rockefeller, IV: 
Chairman: 
Committee on Commerce, Science, and Transportation: 
United States Senate: 

The Honorable Edward J. Markey: 
House of Representatives: 

In 2008, about 7.3 billion pounds of cargo was transported on U.S. 
passenger flights--approximately 58 percent of which was transported 
domestically (domestic cargo) and 42 percent of which was transported 
on flights arriving in the United States from a foreign location 
(inbound cargo).[Footnote 1] The 2009 Christmas Day plot to detonate 
an explosive device during an international flight bound for Detroit 
demonstrates that terrorists continue to view passenger aircraft as 
attractive targets. According to the Transportation Security 
Administration (TSA), the security threat posed by terrorists 
introducing explosive devices in air cargo shipments is significant, 
and the risk and likelihood of such an attack directed at passenger 
aircraft is high.[Footnote 2] Created by the November 2001 Aviation 
and Transportation Security Act, TSA is responsible for the screening 
of all passengers and property, including cargo, U.S. mail, and carry-
on and checked baggage, transported on passenger aircraft.[Footnote 3] 
In addition to TSA, U.S. Customs and Border Protection (CBP) plays a 
role in securing inbound cargo by selectively screening cargo upon its 
arrival in the United States.[Footnote 4] 

To help enhance the security of air cargo, the Implementing 
Recommendations of the 9/11 Commission Act of 2007 (9/11 Commission 
Act) mandated the Department of Homeland Security (DHS) to establish a 
system to physically screen 50 percent of cargo on passenger aircraft--
including the domestic and inbound flights of foreign and U.S. 
passenger operations--by February 2009, and 100 percent of such cargo 
by August 2010.[Footnote 5] The 9/11 Commission Act defines screening 
for purposes of the air cargo screening mandate as a physical 
examination or nonintrusive methods of assessing whether cargo poses a 
threat to transportation security.[Footnote 6] The act also requires 
that such a system provide a level of security commensurate with the 
level of security for the screening of checked baggage. According to 
TSA, the mission of its air cargo security program is to secure the 
air cargo transportation system while not unduly impeding the flow of 
commerce. Although the mandate is applicable to both domestic and 
inbound cargo, TSA stated that it must address the mandate for 
domestic and inbound cargo through separate systems because of 
differences in its authority to regulate domestic and international 
air cargo industry stakeholders. This report will therefore address 
efforts to meet the screening mandate as it applies to domestic and 
inbound cargo separately. 

You asked us to review TSA's progress in meeting the air cargo 
screening mandate. In response to this request, this report addresses 
the following questions: 

1. What progress has TSA made in meeting the 9/11 Commission Act 
screening mandate as it applies to domestic air cargo, and what 
related challenges, if any, does TSA face? 

2. What progress has TSA made in meeting the 9/11 Commission Act 
screening mandate as it applies to inbound air cargo, and what related 
challenges, if any, does TSA face? 

To assess TSA's progress and challenges in implementing a system to 
meet the 9/11 Commission Act screening mandate as it applies to 
domestic cargo, we reviewed TSA's air cargo security policies and 
procedures, screening program documents, technology assessment 
procedures, TSA's Regulatory Activities Plan, the September 2009 air 
cargo interim final rule, and various DHS and industry stakeholder 
reports and testimony related to air cargo security, such as DHS 
Inspector General and industry reports.[Footnote 7] In addition, we 
conducted site visits to four category X U.S. commercial airports and 
one category I U.S. commercial airport that process domestic and 
inbound air cargo.[Footnote 8] We selected these airports based on the 
following criteria: airport size, passenger and air cargo volumes, 
location, and participation in TSA's screening program. At these 
airports, we observed screening operations and technologies and 
interviewed local TSA officials, airport management officials, and 
representatives from 7 air carriers, 24 freight forwarders, 3 
shippers, and 2 handling agents to obtain their views on TSA's system 
to implement the screening mandate.[Footnote 9] We selected these air 
carriers, freight forwarders, shippers, and handling agents based on 
input from TSA and from industry stakeholders. We also interviewed TSA 
air cargo program officials, officials from DHS's Directorate for 
Science and Technology (S&T Directorate), TSA Office of Inspections 
officials, DHS Office of Inspector General officials, Department of 
Commerce officials, three air cargo industry consultants and experts, 
and representatives from six air cargo industry associations that 
represent a variety of air cargo industry stakeholders.[Footnote 10] 
We selected these industry associations because they represent a large 
portion of the air cargo industry. We selected the industry 
consultants and experts based on their experience in the field of 
aviation security, and their recognition in the aviation security 
community. Our site visits and interviews with industry stakeholders 
were based on a nonprobability sample and are not generalizable to the 
entire air cargo industry. However, this sample allowed us to observe 
cargo screening operations and programs in various parts of the 
country with differing air cargo volumes and commodities, and thus 
provided important perspectives on TSA's air cargo screening program. 
We also analyzed TSA data on cargo screening levels and compliance 
violations from February 2009 through December 2009, and TSA data on 
compliance inspections from February 2009 through February 2010. We 
selected these date ranges because the air cargo screening requirement 
started in February 2009 and, at the time of our request, TSA data for 
cargo screening levels, compliance violations, and compliance 
inspections were only available through December 2009, December 2009, 
and February 2010, respectively. To assess the reliability of the 
data, we discussed quality control procedures with agency officials; 
reviewed TSA's data collection, entry, and analysis processes; and 
observed data entry and processing activities for screening data. We 
found the data to be sufficiently reliable to provide a general 
indication of cargo screening and compliance levels. We assessed TSA's 
efforts against criteria for successful project planning and standard 
practices for program management to determine if TSA's efforts 
evaluate staffing implications and include time frames and milestones. 
[Footnote 11] In addition, we assessed TSA efforts against 
qualification testing procedures and time frames established by TSA to 
determine its progress in completing qualification testing of air 
cargo screening technologies. We also assessed TSA's screening 
verification procedures against the Office of Management and Budget's 
guidelines for ensuring information quality to determine if TSA 
reviews and substantiates the integrity of information before it is 
disseminated.[Footnote 12] In addition, we assessed TSA's efforts 
against the agency's policies and procedures and criteria for 
successful project planning to determine if the agency's plan 
considers all phases of the project and includes schedules and 
deadlines.[Footnote 13] Finally, we assessed TSA's plan for meeting 
the screening mandate as it applies to domestic cargo against criteria 
for comprehensive planning to determine whether it included 
contingency planning.[Footnote 14] 

To assess TSA's progress and challenges in implementing a system to 
meet the 9/11 Commission Act screening mandate as it applies to 
inbound air cargo, we reviewed TSA's air cargo policies and procedures 
and various DHS and industry stakeholder reports and testimony related 
to inbound air cargo security. We also interviewed local TSA 
officials, airport management officials, and representatives from 
seven air carriers at the five airports we visited to obtain their 
views on inbound cargo screening issues. In addition, we interviewed 
TSA air cargo program officials, including TSA international cargo 
inspectors, and representatives from six air cargo industry 
associations, and discussed TSA's plans with CBP officials.[Footnote 
15] We assessed TSA's plans for inbound cargo screening verification 
against standard practices for program management.[Footnote 16] We 
also assessed TSA's plan for inbound cargo screening against criteria 
for successful project planning to determine if the agency's plan 
considers all phases of the project and includes schedules and 
deadlines.[Footnote 17] 

We conducted this performance audit from September 2008 through June 
2010 in accordance with generally accepted government auditing 
standards. Those standards require that we plan and perform the audit 
to obtain sufficient, appropriate evidence to provide a reasonable 
basis for our findings and conclusions based on our audit objectives. 
We believe that the evidence obtained provides a reasonable basis for 
our findings and conclusions based on our audit objectives. 

Background: 

Approximately 16 percent of air cargo transported to, from, or within 
the United States is shipped on passenger aircraft, while the 
remainder is transported on all-cargo aircraft.[Footnote 18] Overall, 
approximately 20 million pounds of cargo is transported on domestic 
and inbound passenger aircraft daily.[Footnote 19] This cargo ranges 
in size from 1 pound to several tons and in type from perishable 
commodities to machinery. Air cargo can include such varied items as 
electronic equipment, automobile parts, clothing, medical supplies, 
fresh produce, and human remains. As seen in figure 1, cargo can be 
shipped in various forms, including unit load devices (ULD) that allow 
many packages to be consolidated into one large container or pallet 
that can be loaded onto an aircraft, wooden skids or crates, and 
individually wrapped/boxed pieces, known as loose or break bulk cargo.

[End of figure] 

Participants in the air cargo shipping process include shippers, such 
as individuals and manufacturers of various product types; freight 
forwarders, such as a company that accepts packages and ships them on 
behalf of individuals or manufacturers; air cargo handling agents, who 
process and load cargo onto aircraft on behalf of air carriers; and 
air carriers that load and transport cargo. A shipper may take or send 
its packages to a freight forwarder that in turn consolidates cargo 
from many shippers onto a master air waybill--a manifest of the 
consolidated shipment--and delivers the shipment to air carriers for 
transport. A shipper may also send freight by directly packaging and 
delivering it to an air carrier's ticket counter or sorting center, 
where the air carrier or a cargo handling agent will sort and load 
cargo onto the aircraft. 

TSA's responsibilities for securing air cargo include establishing 
security requirements governing domestic and foreign passenger air 
carriers that transport cargo, and domestic freight forwarders. TSA is 
also responsible for overseeing the implementation of air cargo 
security requirements by air carriers and freight forwarders through 
compliance inspections by transportation security inspectors (TSI)--
staff within TSA responsible for aviation or cargo security 
inspections--and, in coordination with DHS's S&T Directorate, for 
guiding research and development of air cargo security technologies. 
Of the over $5.2 billion provided to TSA for aviation security in 
fiscal year 2010, approximately $123 million is for air cargo security 
as called for in the Conference Report for the DHS Appropriations Act, 
2010. Of this amount, TSA was directed to use $15 million to test, 
evaluate, and deploy screening technologies; to expand canine teams 
operated by TSA by transferring 35 teams from those operated by local 
law enforcement; to deploy technologies to screen skids and pallets; 
and to increase the number of TSIs who oversee participants in the 
newly developed Certified Cargo Screening Program (CCSP)--a voluntary 
cargo screening program for freight forwarders, shippers, and other 
air cargo industry participants.[Footnote 20] For fiscal year 2011, 
TSA has requested approximately $118 million for its air cargo 
security efforts. 

U.S. and foreign air carriers, freight forwarders, and certified cargo 
screening facilities (CCSF)--industry stakeholders that have joined 
the CCSP--are responsible for implementing TSA security requirements, 
including maintaining a TSA-approved security program that describes 
the security policies, procedures, and systems the air carriers, 
freight forwarders, and CCSFs must implement to ensure compliance. 
These requirements include measures related to the acceptance, 
handling, and screening of cargo; training of employees in security 
and cargo screening procedures; testing for employee proficiency in 
cargo screening; and access to cargo areas and aircraft. Air carriers, 
freight forwarders, and CCSFs must also abide by security requirements 
imposed by TSA through security directives and amendments to security 
programs. 

In addition to TSA, CBP and foreign governments play a role in 
securing inbound cargo. Unlike TSA, which requires screening prior to 
departure, CBP determines the admissibility of cargo into the United 
States and is authorized to inspect inbound air cargo for terrorists 
or weapons of mass destruction upon its arrival in the United States. 
[Footnote 21] Foreign governments may also impose their own security 
requirements on cargo departing from their airports. 

The 9/11 Commission Act specifies that air cargo screening methods 
include X-ray systems, explosives detection systems (EDS), explosives 
trace detection (ETD), explosives detection canine teams certified by 
TSA, physical search together with manifest verification, and any 
additional methods approved by the TSA Administrator.[Footnote 22] 
However, solely performing a review of information about the contents 
of cargo or verifying the identity of the cargo's shipper does not 
constitute screening for purposes of satisfying the mandate. Figure 2 
shows some approved screening methods. 

Figure 2: Approved Air Cargo Screening Methods:

TSA Has Made Progress toward Screening 100 Percent of Domestic Cargo 
Transported on Passenger Aircraft, but Remaining Challenges Highlight 
the Need for a Contingency Plan: 

TSA has made progress in meeting the 9/11 Commission Act air cargo 
screening mandate as it applies to domestic cargo, and has taken 
several key steps in this effort, such as increasing the amount of 
domestic cargo subject to screening, creating a voluntary program--the 
CCSP--to allow screening to take place at various points along the air 
cargo supply chain, and taking steps to test air cargo screening 
technologies, among other actions. However, TSA faces several 
challenges in fully developing and implementing a system to screen 100 
percent of domestic air cargo. For example, shipper participation in 
the CCSP has been lower than targeted by TSA. Furthermore, TSA lacks 
information to help ensure that it has the inspection resources it may 
need to provide effective oversight of CCSP entities. In addition, 
there is currently no technology approved or qualified by TSA to 
screen ULD pallets or containers, and TSA is working to complete 
qualification testing of several air cargo screening technologies to 
provide reasonable assurance of their effectiveness. Questions also 
exist about the reliability of the data used to calculate screening 
levels reported by TSA. Moreover, in-transit cargo--such as cargo that 
is transferred from an inbound to a domestic passenger flight--is not 
currently required to undergo physical screening. Finally, TSA has not 
developed a contingency plan to address CCSP participation and 
screening technology challenges, which could be implemented should 
TSA's current efforts not be sufficient to achieve the 100 percent 
screening mandate without impeding the flow of commerce. 

Progress in Meeting the 100 Percent Screening Mandate as It Applies to 
Domestic Cargo: 

TSA has taken several steps to address the air cargo screening mandate. 

TSA increased the amount of domestic cargo subject to screening. 
Effective October 1, 2008, several months prior to the first mandated 
deadline of 50 percent screening by February 2009, TSA established a 
requirement for 100 percent screening of nonexempt cargo transported 
on narrow-body passenger aircraft.[Footnote 23] In 2008, narrow-body 
flights transported about 24 percent of all cargo on domestic 
passenger flights.[Footnote 24] Effective February 1, 2009, pursuant 
to the 9/11 Commission Act, TSA also required air carriers to ensure 
the screening of 50 percent of all nonexempt air cargo transported on 
all passenger aircraft. Furthermore, effective May 1, 2010, air 
carriers were required to ensure that 75 percent of such cargo was 
screened. Although screening may be conducted by various entities, 
according to TSA regulations, each air carrier must ensure that the 
screening requirements are fulfilled. Furthermore, TSA eliminated or 
revised most of its screening exemptions for domestic cargo. For 
example, TSA eliminated the screening exemptions for palletized shrink-
wrapped skids, effective February 2009, and for sealed pharmaceuticals 
and certain electronics, effective September 2009. As a result of the 
elimination of exemptions, most domestic cargo is now subject to TSA 
screening requirements. However, TSA is retaining several of the 
screening exemptions that apply to sensitive cargo.[Footnote 25] 

TSA created a voluntary program to facilitate screening throughout the 
air cargo supply chain. Since TSA concluded that relying solely on air 
carriers to conduct screening would result in significant cargo 
backlogs and flight delays, TSA created the voluntary CCSP to allow 
screening to take place earlier in the shipping process, prior to 
delivering the cargo to the air carrier (see figure 3). Under this 
decentralized approach, air carriers, freight forwarders, shippers, 
and other entities each play an important role in the screening of 
cargo. Under the CCSP, facilities at various points in the air cargo 
supply chain, such as shippers, manufacturers, warehousing entities, 
distributors, third-party logistics companies, and freight forwarders 
that are located in the United States, may voluntarily apply to TSA to 
become CCSFs. Once in the program, they are regulated by TSA. 
According to TSA officials, sharing screening responsibilities across 
the air cargo supply chain is expected to minimize the potential 
increases in cargo transit time, which could result if the majority of 
screening were conducted by air carriers at the airport. While the 
CCSP allows for a number of entities to conduct air cargo screening, 
according to TSA regulations, air carriers are responsible for 
ensuring that all domestic cargo transported on passenger aircraft is 
screened.[Footnote 26] TSA officials stated that effective August 
2010, unscreened domestic cargo would not be transported on passenger 
aircraft.

[End of figure] 

TSA initiated the CCSP at 18 U.S. airports that process high volumes 
of air cargo, and then expanded the program to all U.S. airports in 
early 2009. CCSP participants were certified to begin screening cargo 
as of February 1, 2009. The shipper participants were regulated 
pursuant to an order, and the rules for freight forwarder participants 
were instituted through an amendment to their security programs. 
[Footnote 27] On September 16, 2009, TSA issued an interim final rule 
(IFR) that effective November 16, 2009, regulates the shippers, 
freight forwarders, and other entities participating in the CCSP. 
[Footnote 28] According to the IFR, to become a CCSF, a facility's 
screening measures must be evaluated by TSA or a TSA-approved 
validation firm. Under its certification process, TSA requires each 
CCSF to demonstrate compliance with its security standards that 
include facility, personnel, procedural, perimeter, and information 
technology security. 

Prior to certification, the CCSP applicant must submit for review and 
approval its training programs related to physical screening, facility 
access controls, and chain of custody, among other things. CCSF 
applicants must also implement TSA-approved security programs and 
appoint security coordinators before they can become certified. CCSFs 
must ensure that certain employees have undergone TSA-conducted 
security threat assessments; adhere to control measures for storing, 
handling, and screening cargo; screen cargo using TSA-approved 
methods; and implement chain of custody requirements.[Footnote 29] 
Once certified, CCSFs must apply for recertification, including a new 
examination by TSA or a TSA-approved validator, every 36 months. 

As part of the current program, and using TSA-approved screening 
methods, freight forwarder CCSFs must screen 50 percent of cargo being 
delivered to wide-body passenger aircraft and 100 percent of cargo 
being delivered to narrow-body passenger aircraft. According to TSA, 
although shipper CCSFs are not required to screen shipments to be 
delivered to a passenger aircraft, when they choose to conduct 
screening, such shipments must be screened at 100 percent.[Footnote 
30] In addition, each CCSF must deliver the screened cargo to air 
carriers while maintaining a secure chain of custody to prevent 
tampering with the cargo after it is screened. In fiscal year 2009, 
entities that were certified by TSA to participate in the CCSP were 
subject to annual inspections by TSIs and additional inspections at 
TSA's discretion. According to the 2010 TSI Regulatory Activities 
Plan, the agency plans to conduct at least two comprehensive 
inspections a year (i.e., a review of the implementation of all air 
cargo security requirements) for each CCSP participant. In addition, 
the agency plans to conduct more frequent inspections based on each 
entity's compliance history, among other factors. 

TSA is in the process of clarifying CCSF screening and training 
requirements. During the course of our site visit conducted in July 
2009, we identified two instances where CCSFs misinterpreted CCSP 
screening requirements. For example, a freight forwarder 
representative with whom we spoke stated that the freight forwarder's 
certified facilities have flexibility in the levels of cargo they have 
to screen, such as screening a percentage of cargo on some days while 
not screening any cargo on others. This interpretation is contrary to 
the view of senior TSA officials who are responsible for implementing 
the program, that freight forwarder CCSFs must screen a percentage of 
cargo on a daily basis, as required in their TSA-approved security 
programs. While the extent to which misinterpretation of the CCSP 
requirements occurs among program participants is unclear, the 
instances we identified indicated that freight forwarder CCSFs may not 
be applying TSA screening requirements consistently. When we brought 
this issue to the attention of a senior TSA official, he stated that 
the agency would benefit from strengthening and clarifying CCSP 
screening requirements. In March 2010, TSA officials reported that the 
agency has taken steps to clarify the requirements, though they did 
not specify what those steps were, and said the agency is planning to 
communicate these clarifications to relevant stakeholders. 

During our site visits conducted in June and July 2009, we also 
observed two cases where training materials used by freight forwarder 
CCSFs to educate their employees on the use of technology to screen 
cargo may not have been consistent with TSA screening procedures. For 
example, one freight forwarder representative we interviewed during 
our site visit stated that his company compiled training materials on 
how to screen cargo with ETD technology from public information found 
on the Internet. However, TSA has no way of knowing whether the public 
information gathered from the Internet or from other sources used to 
develop training materials is reliable or consistent with TSA policies 
and procedures. After we brought this issue to the attention of TSA 
officials, TSA reported that the agency plans to clarify the CCSF 
training requirements regarding how to use technology to screen air 
cargo. Specifically, TSA plans to update these requirements in 
amendments to the freight forwarder CCSF policies and procedures. TSA 
officials also stated that the agency is considering providing CCSFs 
with a TSA-approved technology training package or a list of approved 
training vendors that CCSP participants can use to facilitate the 
training of their employees. The agency is in the early stages of this 
effort and has not yet developed time frames for when this effort will 
be completed. 

TSA is conducting outreach efforts to air cargo industry stakeholders. 
Starting in September 2007, TSA began outreach to freight forwarders 
and subsequently expanded its outreach efforts to shippers and other 
entities to encourage participation in the CCSP. While industry 
participation in the CCSP is central to TSA's approach to spread 
screening responsibilities across the U.S. supply chain and, 
ultimately, meet the screening mandate, attracting shippers and 
freight forwarders to join the program is challenging because of the 
effect of the economic downturn on their resources and cargo volume, 
and the perception by some in the shipping and freight forwarder 
industry that screening costs and delays associated with air carriers 
conducting cargo screening will be minimal. TSA is focusing its 
outreach on particular industries, such as producers of perishable 
foods, pharmaceutical and chemical companies, and funeral homes, which 
may experience damage to their cargo if it is screened by a freight 
forwarder or an air carrier. TSA officials stated that they reach out 
to entities through a combination of conferences, outreach meetings, 
Internet presentations, and information posted in numerous trade 
association newsletters and on Web sites. 

To enhance its outreach efforts, TSA established a team of 12 TSA 
field staff, or CCSP outreach coordinators, to familiarize industry 
with the air cargo screening mandate and the CCSP, as well as educate 
potential CCSP applicants on the program requirements.[Footnote 31] In 
addition, outreach coordinators are responsible for certifying cargo 
screening facilities.[Footnote 32] They visit the facilities of the 
CCSP applicants to assess their ability to meet program requirements 
and to address any deficiencies identified during the assessment. To 
complete the certification process, the outreach coordinator ensures 
that the facility has appropriate procedures and training in place to 
screen cargo. According to TSA officials, in February 2009, the agency 
also began using its air cargo TSIs in the field to conduct outreach. 
Officials from the one domestic passenger air carrier association and 
the one freight forwarder association with whom we spoke reported that 
TSA's staff has been responsive and helpful in answering questions 
about the program and providing information on CCSP requirements. 
[Footnote 33] 

TSA is taking steps to test technologies for screening air cargo. The 
9/11 Commission Act specifies that the permitted methods of air cargo 
screening are X-ray systems, EDS, ETD, explosives detection canine 
teams, physical search together with manifest verification, and any 
additional methods approved by the TSA Administrator. However, TSA is 
responsible for determining which specific equipment models are 
authorized for use by industry stakeholders. We reported in March 2009 
that TSA and DHS's S&T Directorate were pilot testing a number of 
technologies to screen air cargo.[Footnote 34] For example, to test 
select screening technologies among CCSFs, TSA created the Air Cargo 
Screening Technology Pilot in January 2008, and selected some of the 
nation's largest freight forwarders to use these technologies and 
report on their experiences.[Footnote 35] The screening that pilot 
participants perform counts toward meeting TSA screening requirements 
and in turn the air cargo screening mandate. In a separate effort, in 
July 2009, DHS's S&T Directorate completed the Air Cargo Explosives 
Detection Pilot Program that tested the performance of select baggage 
screening technologies for use in screening air cargo at three U.S. 
airports. TSA officials stated that the agency will be reviewing the 
pilot results and conducting additional testing on the technologies 
identified in the resulting S&T Directorate report. 

Furthermore, TSA initiated a qualification process to test the 
technologies that it plans to allow air carriers and CCSP participants 
to use in meeting the August 2010 screening mandate against TSA 
technical requirements. In November 2008, in addition to the canine 
and physical search screening methods permitted by TSA to screen air 
cargo, as an interim measure, TSA issued to air carriers and CCSFs a 
list of X-ray, ETD, and EDS models that the agency approved for 
screening air cargo until August 3, 2010.[Footnote 36] TSA approved 
these technologies based on its subject matter expertise and the 
testing and performance of these technologies in the checkpoint and 
checked baggage environments. In March 2009, TSA initiated a 
laboratory and field-based qualification testing process to ensure 
effectiveness of approved and other technologies in the air cargo 
environment and qualify them for use after August 3, 2010.[Footnote 
37] Once the initial stage of the qualification testing process is 
accomplished, TSA's policy is to add successful candidates to a list 
of qualified products for industry stakeholders to utilize when 
purchasing technologies. For example, TSA added X-ray technologies to 
the list of qualified products in October 2009. TSA recommends that 
industry stakeholders purchase technologies from a list of qualified 
products because the technologies that do not pass the qualification 
testing process within 36 months of becoming approved are to be 
removed from a list of products authorized to screen air cargo. After 
issuing the list of qualified products, TSA plans to conduct 
additional stages of qualification testing and evaluation to determine 
the suitability of the screening equipment in an operational setting. 
During the qualification testing process, TSA expects to utilize the 
results of the Air Cargo Screening Technology Pilot and conduct 
additional operational tests independent of the pilot. A description 
of several programs to test screening technologies for air cargo and 
their status is included in table 1. 

Table 1: TSA and DHS Directorate for Science and Technology Programs 
to Test Technologies to Screen Air Cargo: 

Program: Air Cargo Screening Technology Pilot; 
Description: Pilot participants--freight forwarder CCSFs and 
independent cargo screening facilities--operationally test ETD and X-
ray technologies to determine their ability to screen high volumes of 
various cargo types and test chain of custody procedures. TSA provided 
the first round of participants with reimbursements up to $375,000 for 
purchasing technology, and the second with reimbursements up to 
$300,000; 
Status: As of December 31, 2009, 76 of 113 pilot participants were 
reporting screening data to TSA, such as cargo throughput, the number 
of equipment alarms triggered and resolved during screening, and chain 
of custody methods and their cost. TSA plans to complete the pilot in 
August 2010. 

Program: Air Cargo Explosives Detection Pilot; 
Description: DHS tested the effectiveness, cost, and throughput of 
technologies and methods approved for screening checked baggage--EDS, 
ETD, standard X-ray machines, canine teams, and manual screening--in 
the air cargo environment; 
Status: In July 2009, DHS's S&T Directorate submitted the final report 
to Congress that identified some challenges related to applicability 
of technologies to the air cargo environment, such as the limited 
ability of ETD systems to detect threats in an air cargo environment, 
and recommended further technology testing. 

Program: Air Cargo Qualification Testing; 
Description: TSA plans to test the capabilities of four technologies 
to identify a small amount of explosives in air cargo--X-ray, ETD, 
electronic metal detection (EMD), and EDS.[A] TSA determines the 
effectiveness of a particular technology through tests in laboratory 
and operational settings; 
Status: TSA reported that several X-ray technologies have successfully 
passed initial qualification testing and announced which X-ray devices 
qualified in December 2009. In addition, TSA qualified EDS 
technologies based on past testing results, and will initiate 
qualification testing after August 2010. TSA planned to begin initial 
qualification testing for the ETD, EMD, and additional X-ray 
technologies in early 2010, and anticipates qualifying these 
technologies by summer of 2010.

[A] EMD devices are capable of detecting metallic-based explosive 
components, such as wires, within a variety of perishable commodities 
at the cargo piece, parcel, and pallet levels. 

[End of table] 

TSA expanded its explosives detection canine program. TSA has taken 
steps to expand the use of TSA-certified explosives detection canine 
teams. According to TSA, in fiscal year 2009, TSA canine teams 
screened over 145 million pounds of cargo, which represents a small 
portion of domestic air cargo.[Footnote 38] As of February 2010, TSA 
had 113 dedicated air cargo screening canine teams--operating in 20 
major airports--and is in the process of adding 7 additional canine 
teams.[Footnote 39] TSA worked with air carriers to identify peak 
cargo delivery times, in order to schedule canine screening during 
times that would be most helpful to air carriers. TSA also deployed 
canine teams to assist the Pacific Northwest cherry industry during 
its peak harvest season from May through July 2009, to help air 
carriers and CCSFs handling this perishable commodity to meet the 50 
percent screening requirement without disrupting the flow of commerce. 

TSA established a system to verify that screening is being conducted 
at the mandated levels. The agency established a system to collect and 
analyze data from screening entities to verify that requisite levels 
for domestic cargo are being met. Effective February 2009, TSA 
adjusted air carrier reporting requirements and added CCSF reporting 
requirements to include monthly screening reports on the number and 
weight of shipments screened. Based on reporting guidance issued by 
the agency, air carriers and CCSFs provided to TSA the first set of 
screening data in mid-March 2009, to be used as the basis for TSA's 
quarterly reports to Congress.[Footnote 40] Under TSA's current 
process, screening data are manually reviewed and analyzed to 
determine if the screening is conducted at the mandated levels. 
According to TSA officials, the agency plans to transition from a 
manual process to automated data collection, review, and analysis by 
mid-2010. Based on these preliminary data, TSA has determined that 
over 50 percent of air cargo (by weight and number of shipments) 
transported on domestic passenger aircraft has been screened since the 
50 percent requirement went into effect. For fiscal year 2009, TSA 
submitted its 2nd Quarter report, due in May 2009, on October 2, 2009, 
verifying these screening levels.[Footnote 41] The 3rd Quarter report, 
due in August 2009, was submitted on January 7, 2010. The 4th Quarter 
report, due in November 2009, is undergoing Office of Management and 
Budget review. 

TSA is developing a covert testing program to identify security 
vulnerabilities in the air cargo environment. TSA conducts undercover, 
or covert, tests that are designed to approximate techniques that 
terrorists may use in order to identify vulnerabilities in the people, 
processes, and technologies that make up the aviation security system. 
TSA officials reported that the agency plans to carry out a covert 
testing program for the air cargo environment in two phases and will 
conduct tests at shipper, freight forwarder, and air carrier 
facilities.[Footnote 42] Both phases are scheduled to begin in 2010. 
TSA is in the early stages of developing the testing protocols and 
thus has not yet established a timetable for their completion. 
According to TSA officials, the agency plans to use the results of 
these tests to identify and remedy vulnerabilities in the air cargo 
system. 

In addition, TSA operates a risk-based Air Cargo Vulnerability 
Assessment program to identify weaknesses and potential 
vulnerabilities in the domestic air cargo supply chain. As of March 
2010, TSA has conducted assessments at 33 U.S. airports and completed 
assessments at all domestic category X airports in December 2009. 
After completing these assessments, TSA stated that it will utilize 
the results to refine policy for air cargo security. 

Challenges in Meeting the Screening Mandate as It Applies to Domestic 
Air Cargo: 

TSA faces industry participation, oversight, technology, and other 
challenges, and could benefit from a contingency plan to identify 
alternatives for meeting the air cargo screening mandate. 

Lower-Than-Targeted Levels of Shipper Participation in the CCSP Could 
Affect TSA Progress in Meeting the Screening Mandate: 

Although TSA is relying on the voluntary participation of industry 
stakeholders to meet the screening mandate, some stakeholders have not 
participated in the program at targeted levels. As shown in figure 4, 
TSA officials have estimated that an ideal mix of screening to achieve 
the 100 percent mandate as it applies to domestic cargo without 
impeding the flow of commerce would be about one-third of cargo weight 
screened by air carriers, one-third by freight forwarders, and one- 
third by shippers and independent CCSFs.[Footnote 43] The air carrier 
portion includes a small amount of screening by TSA canine teams and 
by TSIs at the smaller category II through IV airports. TSA officials 
emphasized that this estimated ideal mix is not precise but is 
intended to illustrate that balanced industry participation is needed 
to achieve the goals of the program.

Source: GAO analysis of TSA screening data and information. 

Notes: TSA was not able to provide us with screening data more recent 
than March 2010. We found these industry-reported data to be 
sufficiently reliable to provide a general indication of cargo 
screening levels. The reported and ideal screening breakdown 
percentages have been rounded to the nearest percentage point. The 
ideal screening breakdown percentages actually sum to 100 percent. The 
reported screening percentages for December 2009 actually sum to 64 
percent, for February 2010 actually sum to 66 percent, and for March 
2010 actually sum to 68 percent. 

[End of figure] 

However, as of March 2010, the percentage of cargo reported as 
screened by shipper and independent CCSFs remained at 2 percent--far 
lower than the 33 percent TSA cites as the portion these entities 
should ideally screen. To achieve TSA's ideal mix of screening by 
August 2010, shipper and independent CCSF screening efforts would need 
to increase by over sixteenfold. Moreover, as shown in figure 4, the 
total percentage of reported screened cargo rose on average by less 
than a percentage point per month (from 59 to 68 percent) from 
February 2009 through March 2010.[Footnote 44] At these rates, it is 
questionable whether TSA's screening system will achieve 100 percent 
screening of domestic cargo by August 2010 without impeding the flow 
of commerce. Effective May 1, 2010, TSA requires that 75 percent of 
air cargo transported on passenger aircraft be screened. However, even 
if this requirement is met, an additional 25 percent of domestic 
passenger air cargo would still need to be screened in the 3 months 
prior to the August 2010 deadline, including some of the most 
challenging types of cargo to screen, such as ULD pallets and 
containers. 

In March 2010, TSA officials stated that they surveyed current CCSFs 
and CCSP applicants to estimate these air cargo industry stakeholders' 
capacity for screening domestic cargo--this could help predict the 
industry's success in meeting the 100 percent screening deadline. 
[Footnote 45] According to TSA officials, the survey indicated that 
current and prospective CCSFs have the potential capacity needed to 
screen cargo so that short-term delays at only the nation's 18 major 
airports will result when the 100 percent deadline goes into effect. 
However, TSA did not have supporting documentation of the survey's 
methodology or results. Thus, we were unable to independently verify 
TSA's assertions or the rigor of TSA's methodology and analysis. For 
example, it is unclear whether TSA's survey and estimation took into 
account cargo that is inherently difficult to screen, such as ULD 
pallets or containers, or whether it focused primarily on loose cargo 
that is being screened with relative ease. It is also important to 
note that having the potential capacity to screen air cargo does not 
ensure that this capacity will be fully utilized to meet the air cargo 
screening mandate. 

In addition, TSA officials stated that they did not develop milestones 
to monitor CCSP progress because air cargo screening by industry 
stakeholders is driven by market forces that are beyond the control of 
the government and are impossible to forecast. Further, according to 
TSA officials, if the CCSP participants cannot contribute the amount 
of screening needed to achieve 100 percent screening by the August 
2010 deadline, the air carriers will be responsible for screening any 
remaining unscreened cargo at the airport or ensuring that it does not 
fly on a passenger aircraft. However, according to officials from the 
two major air carrier industry associations and the one freight 
forwarder association with whom we spoke, if the volume of cargo is 
too great for air carriers to handle, it could significantly disrupt 
the air cargo industry because of delays from cargo screening at the 
airport and the shift of unscreened cargo to alternate modes of 
transportation, such as all-cargo aircraft or trucks. Officials from 
one major air carrier industry association further noted that this 
would particularly be a problem if the volume of large cargo 
configurations--such as ULD pallets or containers--that air carriers 
have to disassemble and screen is too great for air carriers to 
handle. As discussed earlier, according to TSA officials, these 
disruptions will be short term and limited to 18 major airports. 
However, these 18 airports process 65 percent of domestic cargo 
transported on passenger aircraft, which suggests that disruptions may 
be substantial. TSA's rationale for creating the CCSP, and spreading 
screening responsibilities throughout the supply chain, is to mitigate 
the risks of these sorts of disruptions. However, these CCSP 
participation challenges demonstrate that TSA could benefit from 
developing a contingency plan, as we will discuss later, should it 
become clear that participation rates are not sufficient to achieve 
the screening mandate without impeding the flow of commerce. 

Regulatory and Economic Factors May Affect Industry Participation in 
the CCSP: 

According to TSA officials, some shippers have expressed interest in 
the CCSP, particularly those in certain industries, such as the 
pharmaceutical industry, whose cargo would be compromised if opened 
and screened by others. However, TSA and industry officials reported 
that several factors, such as lack of economic and regulatory 
incentives, are contributing to low shipper participation levels. For 
example, TSA and the freight forwarder industry association official 
with whom we spoke reported that flexibility in applying current TSA 
screening requirements--such as the ability to screen only easier-to-
screen cargo and leave more challenging cargo unscreened--and low 
cargo volumes have minimized screening-related cargo delays and cargo 
screening costs. For example, until the 100 percent screening mandate 
goes into effect in August 2010, air carriers may be able to meet TSA 
screening requirements by screening mostly loose or break-bulk cargo 
and not the more challenging and time-consuming cargo, such as ULD 
pallets and containers or large wooden crates. 

Officials from the domestic passenger air carrier association and 
freight forwarder industry association with whom we spoke reported 
that because of the difficult economic environment and flexibility 
stakeholders have in choosing what cargo to screen, most air carriers 
are not currently charging freight forwarders or shippers for cargo 
screening in order to attract and retain customers. As a result, TSA 
and the domestic passenger air carrier and freight forwarder industry 
association officials we interviewed stated that many shippers and 
freight forwarders are not incurring significant screening costs from 
air carriers, which decreases the financial pressure on the entities 
to join the CCSP and invest resources into screening cargo, factors 
that are making TSA's outreach efforts more challenging. 

Moreover, the freight forwarder industry association official with 
whom we spoke stated that some industry participants may not be able 
to join the program because of potential program costs. TSA has 
estimated in the IFR that the total cost for industry participation in 
the CCSP will be about $2.2 billion over a 10-year period, though the 
agency has not provided per capita cost estimates for industry. The 
freight forwarder industry association official with whom we spoke 
reported that business models of large freight forwarders require them 
to purchase time-saving screening equipment so that screeners can 
avoid physically opening and examining each piece of cargo.[Footnote 
46] However, TSA and this industry official agreed that the majority 
of small freight forwarders-
-which handle 20 percent of the cargo but make up 80 percent of the 
total number of freight forwarding companies--would likely find the 
costs of joining the CCSP, including acquiring expensive technology, 
hiring additional personnel, conducting additional training, and 
making facility improvements, prohibitive. Moreover, shippers that 
distribute products from other companies in addition to or instead of 
their own manufactured goods might also find it cost prohibitive to 
join the CCSP if they were required to purchase screening equipment. 
However, TSA officials stated that most shippers can incorporate 
physical searches into their packing and shipping processes to satisfy 
TSA screening requirements, thereby avoiding such capital expenses. 

TSA established the Air Cargo Screening Technology Pilot program to 
make some financial reimbursement available to large freight 
forwarders and independent CCSFs for the technology they have 
purchased. TSA reported that it targeted high-volume facilities (i.e., 
facilities processing at least 200 ULDs or their equivalent weight of 
approximately 500,000 pounds annually, shipments annually that contain 
cargo consolidated from multiple shippers) for the pilot in order to 
have the greatest effect in helping industry achieve the new screening 
requirements. As of February 2010, 113 CCSFs have joined the pilot. 
However, the majority of CCSFs do not ship large enough volumes of 
consolidated cargo to qualify for the pilot, and thus cannot receive 
funding for technology or other related costs. The freight forwarder 
industry association official with whom we spoke expressed concerns 
regarding the cost of purchasing and maintaining screening equipment. 
In response to concerns of medium and small freight forwarders that 
they might not be able to join the program because of potential costs, 
TSA officials stated that the agency is allowing independent CCSFs to 
join the CCSP and screen cargo on behalf of freight forwarders and 
shippers. In this scenario, small freight forwarders or shippers would 
not need to join the CCSP or purchase technology to avoid screening at 
the airport, but could send their cargo for a fee to an independent 
CCSF for screening. However, TSA and the freight forwarder industry 
association official with whom we spoke stated that the independent 
CCSFs are having difficulties attracting clientèle in the current 
depressed economic environment. According to these officials, shippers 
and other supply chain participants might use independent CCSFs to 
screen their cargo once the 100 percent screening requirement goes 
into effect, if cargo volumes increase before that time or if cargo 
experiences screening delays. Many of the challenges in attracting 
industry participation in the CCSP are outside of TSA's control, and 
agency officials stated that they are working to raise industry 
awareness of the benefits of joining the program through TSA's ongoing 
outreach efforts. 

Determining the Level of Inspection Resources Needed to Effectively 
Oversee CCSP Entities Could Help TSA Efforts to Ensure the Program's 
Success: 

While TSA has amended its Regulatory Activities Plan to include 
inspections of CCSP participants, the agency has not completed its 
staffing study to assess its staffing needs and determine how many 
inspectors will be necessary to provide oversight of the additional 
program participants when the 100 percent screening mandate goes into 
effect.[Footnote 47] TSA's compliance inspections range from reviews 
of the implementation of all air cargo security requirements (i.e., 
comprehensive) to a more frequent review of at least one security 
requirement (i.e., supplemental). TSA recognized that the creation of 
the CCSP added additional regulated entities to TSI oversight 
responsibilities, and incorporated additional inspection requirements 
into the TSI Regulatory Activities Plan. Beginning under the plan for 
fiscal year 2009, TSIs are to perform compliance inspections of new 
regulated entities, such as shippers and manufacturers, that 
voluntarily become CCSFs, as well as new inspections of freight 
forwarder CCSFs that are in addition to inspections related to their 
freight forwarder responsibilities. In addition to their pre-CCSP 
inspection responsibilities, under the plan for fiscal year 2010, TSIs 
are to conduct at least two comprehensive inspections a year for each 
CCSF to verify compliance with the program requirements.[Footnote 48] 

As of March 2010, TSA had 1,258 TSIs, of which 533 were dedicated 
cargo TSIs or cargo TSI canine handlers. The agency was authorized 50 
new cargo TSI positions in fiscal year 2010 to provide additional 
oversight of CCSP operations. TSA officials reported that they have 
developed an interim program-level methodology to allocate these TSIs 
to airports based on CCSP participation and cargo volume, among other 
factors, and that they believe they have a sufficient number of 
inspectors to ensure compliance with the CCSP. However, the agency 
staffing study, which would determine the resources necessary to 
provide CCSP oversight, is not yet complete. According to TSA, the 
agency's staffing study is continuing through fiscal year 2010 and is 
therefore not yet available to provide guidance in helping to plan for 
inspection resources needed to provide oversight. 

Complicating TSA efforts to determine the level of inspection 
resources needed is the extent to which market forces will affect CCSP 
participation and therefore how many additional CCSFs will join the 
program and thus be subject to TSA's inspection requirements. As of 
March 1, 2010, 583 entities had joined the CCSP. Given this level of 
participation, TSA's TSI workforce must conduct at least 1,166 
comprehensive inspections of CCSFs per year. According to our analysis 
of TSA data, in the next year, inspectors will need to at least double 
their comprehensive inspections of CCSFs to reach this target. 
[Footnote 49] Moreover, according to our analysis of TSA data, 
approximately one-quarter to one-third of CCSFs have not received a 
comprehensive inspection.[Footnote 50] 

According to TSA officials, CCSFs that have never been inspected are 
deemed high risk and must be inspected by the following quarter. 
However, since TSA officials anticipate that CCSP participation will 
continue to grow, and that there could be a groundswell in CCSP 
participants as the 100 percent screening deadline approaches, TSIs 
may be challenged in dealing with the increased inspection workload 
once the screening mandate goes into effect in August 2010. For 
example, the IFR stated that about 5,600 entities are expected to join 
the CCSP. Based on these figures, TSA would be required to conduct 
11,200 comprehensive inspections annually. TSA officials questioned 
the accuracy of this estimate, and stated that for workforce planning 
purposes, a more realistic near-term estimate for the number of CCSFs 
TSA is expected to oversee is the number of current CCSFs and CCSP 
applicants. However, TSA did not provide us this total figure. 
Moreover, as discussed earlier, TSA does not know how many CCSFs will 
join the program in the future, and does not plan to estimate the 
number of CCSP participants needed to meet the 100 percent screening 
mandate. Without this key information, it will be difficult for TSA to 
obtain a reasonable estimate of the number of inspectors that will be 
needed to oversee the CCSP participants--highlighting the need for a 
staffing study that considers various scenarios. 

In addition, according to TSA data, of the CCSF compliance inspections 
conducted from February 1, 2009, to December 29, 2009, some resulted 
in at least one violation of CCSF security requirements--and a 
percentage of these violations were screening related.[Footnote 51] 
Having the resources needed to provide effective oversight will be 
critical to ensuring that CCSFs are comprehensively inspected soon 
after being certified, in order to identify violations and provide TSA 
with some assurance that CCSFs are conducting their new screening 
activities in accordance with TSA requirements. 

As we reported in prior work, successful project planning should 
evaluate staffing implications.[Footnote 52] Since fiscal year 2008, 
TSA officials have reported on a planned TSI staffing study, and air 
cargo program officials stated that this study would include an 
analysis of the resources necessary to provide CCSP oversight and 
would incorporate information on the number of CCSFs to be inspected 
in order to assess workforce needs. Officials stated in March 2010 
that the study would continue through fiscal year 2010. However, the 
agency has not established an estimated completion date or interim 
milestones (i.e., dates and related tasks) for completion of the 
study, and officials did not provide an explanation for why this has 
not yet occurred. Standard practices for program management call for 
the establishment of time frames and milestones.[Footnote 53] Creating 
time frames with milestones could help ensure completion of the 
staffing study, the results of which should better position TSA to 
ensure that the inspectors it needs are in place in order to oversee 
effective CCSF implementation of TSA security requirements. 

TSA and Industry Stakeholders Face Challenges in Screening Certain 
Types of Cargo, and TSA Is Working to Test the Effectiveness of 
Screening Technologies: 

TSA faces challenges related to screening certain types of cargo, 
qualification testing of technology, and securing the chain of custody. 

Screening Cargo in ULD Pallets and Containers: 

There is currently no technology approved or qualified by TSA to 
screen cargo once it is loaded onto a ULD pallet or container--both of 
which are common means of transporting air cargo on wide-body 
passenger aircraft. Cargo transported on wide-body passenger aircraft 
makes up 76 percent of domestic air cargo shipments transported on 
passenger aircraft.[Footnote 54] Prior to May 1, 2010, canine 
screening was the only screening method, other than physical search, 
approved by TSA to screen such cargo. Canine teams were deployed to 20 
airports to assist air carriers with such screening. In addition, the 
2009 S&T Directorate technology pilot study reported canine teams to 
be an effective method of screening ULD pallets and containers, but it 
identified an urgent need to find other effective methods for 
screening such cargo because of the shortage of available canine 
teams. TSA officials, however, still have some concerns about the 
effectiveness of the canine teams, and effective May 1, 2010, the 
agency no longer allows canine teams to be used for primary screening 
of ULD pallets and containers. Instead, TSA allows canines to conduct 
primary screening of only loose cargo and 48-by-48-inch cargo skids. 
Canine teams still may be used for secondary screening of ULD pallets 
and containers; however, secondary screening does not count toward 
meeting the air cargo screening mandate. 

TSA officials reported that they have conducted preliminary 
assessments of technologies that are capable of screening ULD pallets 
and containers but that commercially available technologies do not 
exist that effectively detect explosives in the amounts described in 
TSA standards. TSA officials stated that TSA continues to work with 
technology vendors on developing technologies that will be able to 
effectively screen ULD pallets and containers. In the interim, TSA 
officials indicated that the agency is encouraging industry 
stakeholders through the CCSP to screen such cargo earlier in the 
supply chain, before cargo is consolidated. However, according to 
representatives of the two major air carrier industry associations and 
the one freight forwarder association with whom we spoke, technology 
available to screen consolidated or palletized cargo, including cargo 
in a ULD, is critical in meeting the 100 percent screening mandate 
given that such cargo represents a primary means for transporting 
cargo transported on passenger aircraft. Moreover, while industry 
participation in the CCSP may help ensure that screening takes place 
earlier in the supply chain, which will help alleviate the challenges 
posed by ULD pallets and containers, to date, far fewer shippers have 
joined the CCSP than TSA anticipated, and these ULD pallets and 
containers currently make up about 76 percent of domestic air cargo 
transported on passenger aircraft, with no efficient method to screen 
them. These technology challenges suggest the need for TSA to consider 
alternative approaches to meet the screening mandate without unduly 
affecting the flow of commerce, as we will discuss later. 

TSA Is Working to Qualify Some Air Cargo Screening Technologies: 

In addition, TSA is working to complete qualification testing of air 
cargo screening technologies; thus, until all stages of qualification 
testing are concluded, the agency may not have reasonable assurance 
that the technologies that air carriers and program participants are 
currently allowed to use to screen air cargo are effective. 
Qualification tests are designed to verify that a technology system 
meets the technical requirements specified by TSA. TSA qualified 
several X-ray technologies for purchase by industry stakeholders based 
on initial test results and qualified EDS technologies based on their 
past performance in other testing processes. TSA has not yet qualified 
ETD and other X-ray technologies that TSA allows program participants 
to use to screen air cargo. Once these technologies have been added to 
the list of qualified products, the agency is to conduct additional 
stages of qualification testing. TSA officials expressed confidence in 
the initial qualification test results because the commercial off-the- 
shelf technologies being used for cargo screening have a proven record 
in the passenger checkpoint and checked baggage environments. However, 
TSA acknowledged that if the results of additional stages of 
qualification testing do not meet its technical requirements, these 
technologies can be removed from the list of qualified products. 

Furthermore, because of the mandated deadlines, TSA is conducting 
qualification testing to determine which screening technologies are 
effective at the same time that air carriers are using these 
technologies to meet the mandated requirement to screen air cargo 
transported on passenger aircraft. For example, according to TSA, ETD 
technology will undergo the initial phase of qualification testing in 
the air cargo environment in 2010, although many air carriers and 
CCSFs are currently using it to screen air cargo. Moreover, technology 
reports and TSA officials disagree as to the effectiveness of ETD 
technology. For example, a pilot program completed by DHS's S&T 
Directorate in July 2009 found that the ability of ETD technology to 
detect explosive threats in cargo by sampling the external surfaces of 
cargo shipments for explosive residue--the standard ETD protocol 
required by TSA--is poor. According to TSA officials, external 
sampling of cargo shipments is a method of screening preferred by 
freight forwarders and air carriers in order to avoid opening all 
cargo pieces, which can result in possible damage to the contents and 
significantly greater screening time. The pilot program recommended 
further research to evaluate the applicability and efficacy of 
external sampling using ETD systems, as well as other screening 
systems, to detect threats, such as explosives, in air cargo. However, 
TSA officials disputed the findings of this S&T Directorate study. 
They also stated that other S&T Directorate reports support the 
acceptance of ETD technology; however, we were unable to review these 
reports since this information was provided late in our review. 
[Footnote 55] The lack of consensus within DHS regarding the 
effectiveness of ETD technology in the air cargo environment suggests 
the need for additional study. 

Although TSA officials stated that simultaneous testing and use of 
technology by the industry is not ideal, they noted that this was 
necessary to meet the screening deadlines mandated by the 9/11 
Commission Act. While we recognize that certain circumstances, such as 
mandated deadlines, require expedited deployment of technologies, our 
prior work has shown that programs with immature technologies have 
experienced significant cost and schedule growth.[Footnote 56] For 
example, we reported in October 2009 that TSA deployed a passenger 
checkpoint technology--the explosives trace portal (ETP)--to airports 
without proving its performance in an operational environment, 
contrary to TSA's acquisition guidance, which recommends such testing. 
[Footnote 57] The agency purchased hundreds of these machines but was 
forced to halt their deployment because of performance, maintenance, 
and installation issues. All but 9 ETPs have been withdrawn from 
airports and 18 remain in inventory. TSA determined that the remainder 
of the ETPs was excess capacity. 

Since TSA plans to issue a list of qualified technologies before all 
stages of qualification testing are complete, the industry lacks 
assurance that the qualification status of technologies established by 
TSA for use after August 2010 will not change. Further testing could 
result in modifications to the list of qualified technologies 
authorized for use after August 3, 2010, and to the list of 
technologies approved by TSA for use through January 2012. TSA has 
reserved the option of revising the status of any particular 
technology or system in the event that its performance in an 
operational environment indicates that it is losing effectiveness or 
suitability to an unacceptable degree as it ages or that constantly 
evolving threats require new detection capabilities. The domestic 
passenger air carrier and freight forwarder industry association 
officials with whom we spoke expressed concerns about purchasing 
technology from the lists of approved and qualified technologies that 
are subject to change. TSA officials stated that the agency is 
accelerating its testing timeline and the release of the qualification 
testing results for these technologies to meet the screening deadlines 
mandated by Congress. For example, TSA originally planned to release 
the X-ray qualification results after completing all stages of 
qualification testing. Because of approaching deadlines, however, in 
December 2009 and based on initial test results, TSA announced the 
qualification of certain X-ray technologies. It is unclear, however, 
whether the challenges TSA faces in issuing a list of fully qualified 
screening technologies will allow the industry to make informed 
decisions about technology purchases to meet the screening 
requirements of the 9/11 Commission Act. 

Securing the Chain of Custody in the Air Cargo Shipping Process: 

With regard to technology, another area of concern in the 
transportation of air cargo is the chain of custody between the 
various entities that handle and screen cargo before it is loaded onto 
an aircraft. TSA officials stated that the agency has taken steps to 
analyze the chain of custody under the CCSP, and has issued cargo 
procedures to all entities involved in the CCSP to ensure that the 
chain of custody of cargo is secure. We found that the procedures 
issued by TSA to the CCSFs include guidance on when and how to secure 
cargo with tamper-evident technology, but do not include standards for 
the types of technologies that should be used. TSA officials noted 
that they are in the process of compiling a list of existing tamper-
evident technologies and their manufacturers. Once the list is 
complete, TSA plans to test and evaluate these technologies and issue 
recommendations to the industry. TSA has not yet set any time frames 
for issuing such recommendations because, according to TSA officials, 
they need to explore cost-effective technologies first. 

Securing the chain of custody for cargo screened under the CCSP takes 
on additional significance in light of the DHS Inspector General's 
2009 report findings that TSA could improve its efforts to secure air 
cargo during ground handling and transportation.[Footnote 58] For 
example, the report determined that industry personnel were accessing, 
handling, or transporting cargo without the required background 
checks. In addition, the report stated that TSA's inspection process 
has not been effective in ensuring that requirements for securing air 
cargo during ground transportation are understood or followed. In 
response to the DHS Inspector General report, TSA concurred with the 
recommendation to improve the security threat assessment process and 
stated that the IFR requires recordkeeping for security threat 
assessments. TSA also concurred with the DHS Inspector General 
recommendation to revise the Regulatory Activities Plan to allow more 
time for inspectors to provide support and education to regulated 
entities to ensure that air cargo security requirements are understood 
and implemented. TSA reported that the fiscal year 2010 Regulatory 
Activities Plan addresses this concern. 

TSA Is Working to Verify That Domestic Screening Is Being Conducted at 
the Requisite Levels, but Questions Exist about the Reliability of the 
Reported Data: 

While TSA reported to Congress that industry achieved the February 
2009 50 percent screening deadline as it applies to domestic cargo, 
questions exist about the reliability of the screening data, which are 
self-reported by industry representatives. TSA has been collecting and 
analyzing data from screening entities, such as air carriers, freight 
forwarders, and shippers, since March 2009 to verify that domestic 
screening is being conducted at the requisite levels. As of March 2010 
TSA reported that 68 percent of domestic cargo by weight had been 
screened. After receiving data from screening entities, TSA performs 
preliminary data quality checks, such as viewing the data to identify 
missing or duplicate values. However, TSA does not have a mechanism to 
verify the accuracy of the data reported by the industry.[Footnote 59] 
TSA stated that as part of its compliance inspections for air carriers 
and CCSFs, TSIs check industry screening logs--which include 
information on how and by whom a specific shipment was screened--to 
verify that the required screening levels have been met. However, TSIs 
do not compare these screening logs to the reports that air carriers 
and CCSFs submit to TSA with their screening levels because according 
to senior TSA officials, such comparisons would be significantly 
burdensome to the industry. Specifically, senior TSA officials stated 
that the air carrier reports do not contain details on specific 
shipments, thus verification is not feasible. However, senior TSA 
officials agreed that it is important to verify the accuracy of the 
data reported by the industry through random checks or other practical 
means, and that greater coordination among TSA program and compliance 
officials is necessary to ensure that these checks are taking place. 
The Office of Management and Budget's guidelines for ensuring quality 
of information call for agencies to develop procedures for reviewing 
and substantiating the integrity of information before it is 
disseminated.[Footnote 60] Given that TSA uses the data submitted by 
screening entities to verify its compliance with the mandate as it 
applies to domestic cargo and to report to Congress, ensuring the 
accuracy of the self-reported data is of particular significance. In 
order to do this, TSA could, for example, adopt a program similar to 
CBP's compliance measurement program, which is used to determine the 
extent to which importers are in compliance with laws and regulations. 
As part of this program, CBP conducts regular quality reviews to 
ensure accuracy in findings and management oversight to validate 
results. Verifying the accuracy of the self-reported screening data 
could better position TSA in providing reasonable assurance that 
screening is being conducted at reported levels. 

TSA Requirements Do Not Ensure That In-Transit Cargo Transferred from 
an Inbound to a Domestic Flight Is Physically Screened: 

Cargo that has already been transported on one leg of a passenger 
flight--known as in-transit cargo--may be subsequently transferred to 
another passenger flight without undergoing screening. For example, 
cargo transported on an inbound flight, a significant percentage of 
which is exempt from screening, can be transferred to a domestic 
flight without physical screening.[Footnote 61] According to TSA 
officials, though the agency does not have a precise figure, industry 
estimates suggest that about 30 percent of domestic cargo is 
transferred from an inbound flight. According to TSA officials, the 
agency had determined that additional screening of this cargo was not 
required, in part because an actual flight mimics a screening method 
that until recently was approved for use.[Footnote 62] 

A senior TSA official also stated that because in-transit cargo 
transferred from an inbound flight has flown under a TSA-approved 
passenger aircraft security program, it is in compliance with TSA 
screening requirements. However, a significant amount of inbound cargo 
is exempt from screening.[Footnote 63] In contrast, TSA's policies and 
procedures require all cargo flown on domestic flights to be screened 
at 75 percent, effective May 1, 2010. As a result, despite being flown 
under a TSA-approved security program, in-transit cargo originating in 
foreign countries is not required to be screened at the same levels as 
cargo transported on domestic flights. Therefore, TSA lacks assurance 
that this cargo is being screened in accordance with 9/11 Commission 
Act required screening levels. 

In response to our questions as part of this review, TSA officials 
stated that transporting in-transit cargo without screening could pose 
a vulnerability, but as of February 2010, the agency was not planning 
to require in-transit cargo transferred from an inbound flight to be 
physically screened because of the logistical difficulties associated 
with screening cargo that is transferred from one flight to another. 
However, these logistical difficulties could be minimized if more 
cargo were screened prior to departure from a foreign location. Thus, 
addressing the potential security vulnerability posed by in-transit 
cargo is directly linked to TSA's efforts to secure and screen inbound 
cargo, which is discussed later in this report. Although TSA officials 
stated that they plan to explore measures for screening in-transit 
cargo in the future, these officials did not provide documentation of 
these measures or information on milestones for their implementation. 
A successful project plan--such as a plan that would be used to 
establish such measures--should consider all phases of the project, 
and clearly state schedules and deadlines.[Footnote 64] Developing a 
plan with milestones that addresses how in-transit cargo will be 
screened in accordance with 9/11 Commission Act requirements could 
better position TSA to meet the mandate and reduce potential 
vulnerabilities associated with such cargo. 

Contingency Planning Could Help TSA Identify Alternatives for Meeting 
the Air Cargo Screening Mandate: 

Although TSA faces industry participation and technology challenges 
that could impede the CCSP's success and the agency's efforts to meet 
the 100 percent screening mandate, the agency has not developed a 
contingency plan that considers alternatives to address these 
challenges. As discussed earlier, as of December 2009, the percentage 
of cargo screened by shipper and independent CCSFs remains far lower 
than the percentage TSA cites as the portion these entities should 
ideally screen. Without adequate CCSP participation, industry may not 
be able to screen enough cargo prior to its arrival at the airport to 
maintain the flow of commerce while meeting the mandate. Likewise, 
without technology solutions for screening cargo in a ULD pallet or 
container--which makes up about 76 percent of cargo transported on 
domestic passenger aircraft--industry may not have the capability to 
effectively screen 100 percent of air cargo without affecting the flow 
of commerce. TSA is continuing to work with vendors on developing 
technology to effectively screen ULD pallets and containers, and in 
the interim, is encouraging industry stakeholders as part of the CCSP 
to screen such cargo earlier in the supply chain, before it is loaded 
onto ULDs, but such actions will not ensure that such cargo is 
screened. We have previously reported that a comprehensive planning 
process, including contingency planning, is essential to help an 
agency meet current and future capacity challenges.[Footnote 65] 
Alternatives could include, but are not limited to, mandating CCSP 
participation for certain members of the air cargo supply chain--
instead of relying on their voluntary participation--and requiring the 
screening of some or all cargo before it is loaded onto ULD pallets 
and containers. Developing a contingency plan that addresses the 
participation and technology challenges that could impede the 
screening program's success, and identifies alternate or additional 
security measures to implement in case the program is unable to 
effectively facilitate the screening of sufficient amounts of cargo 
prior to reaching air carriers at the airport, could better position 
TSA to meet the requirements in the air cargo screening mandate. 

With regard to the consideration of alternatives to the CCSP, TSA 
reported that it considered requiring air carriers to bear the full 
burden of the screening mandate and also considered creating TSA- 
operated screening facilities at airports, but determined that both 
strategies would result in severe disruptions to commerce because of 
limited airport space for screening. Representatives of the two major 
air carrier associations with whom we spoke stated that additional TSA 
screening by canine teams would be helpful, and industry stakeholders 
have also identified the option of using private companies to provide 
canine screening in order to expand the number of canines available 
for screening. According to TSA, the agency is considering whether to 
pursue this option because of concerns regarding certification of 
canines that have not been trained by TSA and are not handled by TSA 
staff. In addition, TSA officials stated that the agency does not plan 
to provide canine teams as a long-term primary screening method once 
the CCSP grows and industry develops more capacity to screen cargo, as 
industry, not the federal government, is responsible for screening air 
cargo under TSA's regulations. 

TSA officials also stated that alternative or additional screening 
measures will not be necessary because unscreened cargo will simply 
not be transported on passenger aircraft, that is, "will not fly." 
Although this approach would ensure that 100 percent of air cargo 
transported on passenger aircraft is screened, part of TSA's mission 
is ensuring the flow of commerce. Not transporting unscreened cargo 
could place the air cargo transportation industry at risk of 
experiencing economic disruptions, including shifts of cargo to other 
modes of transportation, which could negatively affect the air cargo 
business. In order to help ensure that it fulfills its mission and 
meets the 9/11 Commission Act mandate, TSA could benefit from 
identifying alternative measures in a contingency plan, should it 
become clear that the CCSP will not achieve the screening mandate 
while maintaining the flow of commerce. 

TSA Has Made Progress but Faces Several Challenges and Lacks a Plan 
for Achieving 100 Percent Screening of Inbound Cargo: 

TSA has made progress toward meeting the screening mandate as it 
applies to inbound cargo by taking steps to increase the percentage of 
inbound air cargo that has undergone screening. However, the agency 
faces several challenges in ensuring that 100 percent of inbound air 
cargo is screened, which will prevent it from meeting the mandate by 
the August 2010 deadline. While TSA is aware that it is unable to meet 
the screening mandate as it applies to inbound cargo, it has not yet 
determined when or how it will eventually meet the deadline. 

TSA Has Taken Several Steps to Increase the Percentage of Inbound 
Cargo Being Screened: 

TSA has taken several steps to increase the percentage of inbound air 
cargo being screened. For example, TSA revised its requirements for 
foreign and U.S. air carrier security programs, effective May 1, 2010, 
to generally require air carriers to screen a certain percentage of 
shrink-wrapped and banded inbound cargo and 100 percent of inbound 
cargo that is not shrink-wrapped or banded.[Footnote 66] According to 
our analysis of TSA information, shrink-wrapped and banded cargo makes 
up approximately 96 percent of inbound cargo, which means that a 
significant percentage of inbound air cargo is not required to be 
screened.[Footnote 67] According to TSA, implementation of this 
requirement will result in the screening of 100 percent of inbound 
cargo transported on narrow-body aircraft since none of this cargo is 
shrink-wrapped or banded.[Footnote 68] 

Since TSA does not have the same regulatory reach to the supply chain 
in foreign countries as it does in the United States, it is taking a 
different approach to implementing the screening mandate as it applies 
to inbound cargo. This approach focuses on harmonizing its security 
standards with those of other nations.[Footnote 69] For example, TSA 
is working with foreign governments to increase the amount of screened 
cargo, including working bilaterally with the European Commission (EC) 
and Canada, and quadrilaterally with the EC, Canada, and Australia. As 
part of these efforts, TSA recommended to the United Nations' 
International Civil Aviation Organization (ICAO) that the next 
revision of Annex 17 to the Convention of International Civil Aviation 
include an approach that would allow screening to take place at 
various points in the air cargo supply chain.[Footnote 70] According 
to TSA, ICAO's Aviation Security Panel met in March 2010 to finalize 
revisions to Annex 17, including TSA's proposed revision to add 
"screening" as a supply chain security concept. TSA has also supported 
the International Air Transport Association's (IATA) efforts to 
establish a secure supply chain approach to screening cargo for its 
member airlines and IATA's efforts to have these standards recognized 
internationally.[Footnote 71] 

In addition, TSA is working with CBP to leverage an existing CBP 
system, known as the Automated Targeting System (ATS), to identify and 
target elevated-risk inbound air cargo. ATS is a model that combines 
information from inbound cargo manifest lists and entry declaration 
information into shipment transactions and uses historical and other 
data to help target cargo shipments for inspection.[Footnote 72] While 
CBP currently uses ATS to identify cargo for screening once it arrives 
in the United States, according to officials, TSA has established a 
TSA-CBP working group to focus on using ATS to target inbound air 
cargo for possible screening prior to departure from foreign 
locations. TSA and CBP officials stated that the working group met 
regularly since June 2009, though agency officials did not specify how 
frequently they met. As of February 2010, TSA and CBP officials stated 
that they were conducting an exercise at Dulles International Airport 
for TSA to observe CBP's use of ATS, understand the full capabilities 
of ATS, and determine whether ATS can assist TSA's inbound air cargo 
screening efforts. TSA officials said that they were not in a position 
to provide time frames for completing the exercise since the effort is 
in the early stages. Should TSA determine that ATS is effective for 
targeting the screening of inbound air cargo, TSA plans for air 
carriers to conduct the screening of shipments identified as elevated 
risk prior to the cargo's transport to the United States. The air 
carriers will also be responsible for providing TSA with the results. 
In discussing how a system to target certain, elevated-risk shipments 
for screening will fit into TSA's overall plans to screen 100 percent 
of inbound air cargo, officials stated that ATS would provide an 
additional layer of scrutiny for all cargo entering the United States. 
[Footnote 73] 

To help assess the rigor and quality of foreign screening practices, 
TSA is also in the process of obtaining information from foreign 
countries on their respective air cargo screening levels and 
practices. According to officials, the agency has developed an 
assessment methodology in a question and answer format to collect 
information on each foreign country's air cargo security practices, 
and it has used the new methodology to collect initial information 
from one country. TSA has indicated that it will use the methodology 
to identify key security practices and that the information collected 
will also help determine if these practices are comparable to TSA 
requirements, which will provide TSA with details that can help 
determine how foreign standards align with TSA standards. TSA 
officials indicated that the methodology used to collect the 
information is part of a larger process that will involve collecting 
initial information, analyzing what was received, and submitting 
additional questions to the foreign countries. TSA anticipates storing 
the information gathered in a database, which it has not yet created. 
TSA officials were unable to provide time frames for use of the 
assessment methodology or completing the database because the effort 
is in the early stages. 

TSA Faces Several Challenges in Meeting the Screening Mandate as It 
Applies to Inbound Cargo: 

While TSA has taken steps to increase the percentage of inbound cargo 
that has undergone screening, the agency faces several challenges in 
meeting the mandate. Consequently, TSA has stated that it will not be 
able to meet the screening mandate as it applies to inbound cargo. For 
example, in a March 4, 2010, hearing before the Subcommittee on 
Homeland Security, House Committee on Appropriations, in responding to 
questions, the Acting TSA Administrator stated that it could take 
several years before 100 percent of inbound cargo is screened. 
According to TSA, screening inbound air cargo poses unique challenges, 
related, in part, to TSA's limited ability to regulate foreign 
entities. As such, TSA officials stated that the agency is focusing 
its air cargo screening efforts on domestic cargo and on screening 
elevated-risk inbound cargo as it works to address the challenges it 
faces in screening 100 percent of inbound cargo. 

Inbound air cargo is currently being screened at lower levels than 
domestic air cargo. For example, while TSA removed almost all its 
screening exemptions for domestic cargo, TSA requirements continue to 
exempt from screening a significant amount of shrink-wrapped air cargo 
transported to the United States, which represents about 96 percent of 
all inbound cargo.[Footnote 74] Effective May 1, 2010, TSA requires 
that a certain percentage of this cargo be screened. In April 2007, we 
reported that TSA's screening exemptions for inbound cargo could pose 
a risk to the air cargo supply chain and recommended that TSA assess 
whether these exemptions pose an unacceptable vulnerability and, if 
necessary, address these vulnerabilities. TSA agreed with our 
recommendation, but beyond expanding its requirement to screen 100 
percent of inbound air cargo transported on narrow-body aircraft and a 
certain percentage of inbound cargo that is shrink-wrapped or placed 
on banded skids, has not yet reviewed, revised, or eliminated 
screening exemptions for cargo transported on inbound passenger 
flights, and did not provide a time frame for doing so.[Footnote 75] 
We continue to believe that TSA should assess whether these exemptions 
pose an unacceptable security risk. TSA officials stated that once the 
modified ATS is in place, screening exemptions will be less relevant 
because air carriers will be more able to target the screening of 
elevated-risk cargo as an interim measure before 100 percent screening 
is achieved. However, the 9/11 Commission Act requires that all air 
cargo be physically screened and does not make exceptions for cargo 
that is not elevated risk. 

TSA faces challenges in meeting the 100 percent screening mandate as 
it applies to inbound air cargo. For example, although TSA is 
authorized under U.S. law to ensure that all air carriers, foreign and 
domestic, operating to, from, or within the United States maintain the 
security measures included in their TSA-approved security programs and 
any applicable security directives or emergency amendments issued by 
TSA, this authority is limited.[Footnote 76] Also, TSA has no legal 
jurisdiction over foreign nations. Specifically, TSA has been 
authorized by Congress to set standards for aviation security, 
including the authority to require that inbound cargo be screened 
before it departs for the United States. However, the agency also 
relies on foreign governments to implement and enforce--including 
conducting actual screening, in some cases--TSA's regulatory 
requirements. 

Harmonizing TSA regulatory standards with those of foreign governments 
may be challenging because these efforts are voluntary and some 
foreign countries do not share the United States' concerns regarding 
air cargo security threats and risks. TSA officials caution that if 
TSA were to impose a strict cargo screening standard on all inbound 
cargo, many nations likely would be unable to meet such standards in 
the near term. This raises the prospect of reducing the flow of cargo 
on passenger aircraft. According to TSA, the effect of imposing such 
screening standards in the near future could result in increased costs 
for international passenger travel and for imported goods and possible 
reduction in passenger traffic and foreign imports. According to TSA 
officials, this could also undermine TSA's ongoing cooperative efforts 
to develop commensurate security systems with international partners. 
TSA's ongoing efforts to harmonize security standards with those of 
foreign nations are essential to achieving progress toward meeting the 
100 percent screening mandate as it applies to inbound air cargo. 

Identifying the precise level of screening being conducted on inbound 
air cargo is difficult because TSA lacks a mechanism to obtain actual 
data on all screening that is being conducted on inbound air cargo. 
TSA officials estimate that 55 percent of inbound cargo by weight is 
currently being screened and that 65 percent of inbound cargo by 
weight will be screened by August 2010.[Footnote 77] However, these 
estimates are based on the current screening requirements of certain 
countries and are not based on actual data collected from air carriers 
or other entities, such as foreign governments, on what percentage of 
cargo is actually being screened.[Footnote 78] For example, if a 
country requires that 100 percent of its cargo be screened, as the 
United Kingdom does, TSA counts all the cargo coming from that country 
as screened. While TSA officials stated that they discuss screening 
percentages with foreign government officials, the agency does not 
conduct any additional data verification to assess whether screening 
is conducted at, above, or below the required levels. In addition, 
because TSA's efforts to complete assessments of other countries' 
screening requirements are ongoing, the agency does not always know 
whether the screening requirements are consistent with TSA standards. 
The DHS Appropriations Act, 2009, requires TSA to report on the actual 
screening being conducted, by airport and air carrier.[Footnote 79] To 
improve data collection efforts, as of May 2010, TSA requires air 
carriers to report on their actual screening levels for inbound air 
cargo, and TSA officials stated that an automated cargo reporting tool 
would be operational in May 2010 for this purpose. The May 2010 
security program changes only require air carriers to report on the 
screening that they conduct and not on the screening conducted by 
other entities in the air cargo supply chain to meet the air cargo 
screening mandate. TSA officials stated that it may be challenging to 
obtain screening data from some foreign governments and other entities 
that conduct cargo screening. As such, TSA officials also stated that 
the agency may still use estimates, such as the current screening 
requirements of certain countries, when reporting data to Congress. 
Officials could not provide information on milestones or time frames 
for obtaining actual screening data for all inbound screening, 
including that conducted by air carriers and other entities in the air 
cargo supply chain, because the agency is still working to overcome 
inbound regulatory challenges. However, establishing time frames for 
implementing a plan is consistent with standard practices for program 
management.[Footnote 80] Finalizing a plan to obtain actual screening 
data could help TSA obtain greater assurance that mandated screening 
levels are being met. 

TSA Has Not Yet Determined How It Will Meet the Screening Mandate as 
It Applies to Inbound Cargo: 

TSA has not yet determined how it will meet the screening mandate as 
it applies to inbound air cargo. Although TSA has taken steps to 
increase the percentage of inbound cargo transported on passenger 
aircraft that is screened, the agency has not developed a plan, 
including milestones, for meeting the mandate as it applies to inbound 
cargo. While TSA officials have stated that the agency does not expect 
to meet the mandate as it applies to inbound cargo by the August 2010 
deadline, TSA has not provided estimates of when the mandate will be 
met or when steps toward its achievement will be completed. Moreover, 
the steps that the agency is taking to enhance inbound air cargo 
security do not fully support the 100 percent cargo screening mandate. 
For example, TSA is focusing on developing its ability to utilize 
CBP's ATS to target elevated-risk cargo for screening. While we 
recognize this as a reasonable step to strengthen inbound air cargo 
security, TSA does not have a plan that articulates how this and other 
steps it is taking will fit together to achieve 100 percent screening. 

The 9/11 Commission Act requires the establishment of a system to 
screen 100 percent of cargo transported on passenger aircraft, 
including inbound cargo. As we have reported in our prior work, a 
successful project plan--such as a plan that would be used to 
establish such a system--should consider all phases of the project and 
clearly state schedules and deadlines[Footnote 81]. TSA reported that 
it is unable to identify a timeline for meeting the mandate for 
inbound cargo, stating that its efforts are long term, given the 
extensive work it must conduct with foreign governments and 
associations. However, interim milestones could help the agency 
provide reasonable assurance to Congress that it is taking steps to 
meet the mandate as it applies to inbound cargo. A plan that considers 
all phases of the project and clearly states schedules and deadlines 
could help position TSA to better measure progress it is making toward 
meeting the 9/11 Commission Act mandate as it relates to inbound air 
cargo and provide reasonable assurance that its efforts are 
implemented in a relatively timely manner. 

Conclusions: 

Meeting the August 2010 mandate to establish a system to physically 
screen 100 percent of air cargo transported on passenger aircraft is a 
daunting task. In August 2010, unscreened cargo will not be allowed to 
fly on passenger aircraft, but leaving behind such cargo could affect 
the flow of commerce. Although the CCSP should help TSA meet the 
mandate as it applies to domestic cargo, addressing certain challenges 
could strengthen agency efforts and help ensure the CCSP's success. 
For example, TSA might benefit from developing a contingency plan 
should it become clear that participation levels are not sufficient to 
achieve the screening mandate without disruptions to the flow of 
commerce. Establishing milestones for completion of a staffing study 
to determine the number of inspectors needed to oversee CCSP 
participants could provide results that should better position TSA to 
obtain these inspection resources and help ensure that air carriers 
and CCSFs comply with TSA requirements. Moreover, the technology 
challenges TSA faces in screening cargo once it is loaded onto ULD 
pallets and containers highlight the need for a contingency plan in 
the event that industry stakeholders do not have the capacity to 
screen such air cargo. In addition, verifying industry-reported 
screening data could better position TSA in providing reasonable 
assurance that screening is being conducted at reported levels. 
Furthermore, developing a plan and milestones for screening in-transit 
cargo, which is not currently required to undergo physical screening, 
could help ensure that such cargo is screened in accordance with 9/11 
Commission Act requirements and mitigate a risk to the air cargo 
transportation system. Developing a contingency plan that considers 
additional or alternative security measures will better position TSA 
to meet the mandate without disrupting the flow of commerce should it 
become clear that the challenges related to CCSP participation and 
screening technology will hinder the agency's efforts. 

With regard to inbound air cargo, while TSA has taken some positive 
steps to increase the percentage of cargo that is screened, the agency 
could better address the challenges to screening this cargo. For 
example, finalizing its plans to obtain actual screening data for all 
inbound cargo screening, including time frames and milestones, could 
provide greater assurance that mandated screening levels are being 
met. In addition, determining how it will meet the screening mandate 
as it applies to inbound air cargo, including related milestones, 
could better position TSA in providing reasonable assurance that the 
agency is making progress toward meeting the screening mandate in a 
timely manner. 

Recommendations for Executive Action: 

To enhance efforts to secure the air cargo transportation system and 
establish a system to screen 100 percent of air cargo transported on 
passenger aircraft, we are recommending that the Administrator of TSA 
take the following five actions: 

* Establish milestones for the completion of TSA's staffing study to 
assist in determining the resources necessary to provide CCSP 
oversight. 

* Develop a mechanism to verify the accuracy of all screening data, 
both self-reported domestic data and inbound cargo data, through 
random checks or other practical means. For inbound air cargo, 
complete the agency's plan to obtain actual data, rather than 
estimates, for all inbound screening, including establishing time 
frames and milestones for completion of the plan. 

* Develop a plan, with milestones, for how and when the agency intends 
to require the screening of in-transit cargo. 

* Develop a contingency plan for meeting the mandate as it applies to 
domestic cargo that considers alternatives to address potential CCSP 
participation shortfalls and screening technology limitations. 

* Develop a plan, with milestones, for how and when the agency intends 
to meet the mandate as it applies to inbound cargo. 

Agency Comments and Our Evaluation: 

We provided a draft of our report to DHS and TSA on May 19, 2010, for 
review and comment. On June 23, 2010, DHS provided written comments 
from the department and TSA, which are reprinted in appendix I. In 
commenting on our report, TSA stated that it concurred with three 
recommendations, concurred in part with one recommendation, and did 
not concur with another recommendation. For the recommendations for 
which TSA concurred or concurred in part, the agency identified 
actions taken or planned to implement them. Although TSA concurred 
with part of our second recommendation, the actions TSA reported that 
the agency has taken do not fully address the intent of this 
recommendation. 

Regarding our first recommendation that TSA establish milestones for 
the completion of its staffing study to assist in determining the 
resources necessary to provide CCSP oversight, TSA concurred. TSA 
stated that as part of the staffing study, the agency is working to 
develop a model to identify the number of required TSIs and that this 
effort would be completed in the fall of 2010. If this model includes 
an analysis of the resources needed to provide CCSP oversight under 
various scenarios, it will address the intent of our recommendation. 

TSA concurred in part with our second recommendation that the agency 
develop a mechanism to verify the accuracy of domestic and inbound 
screening data, including obtaining actual data on all inbound 
screening. TSA concurred with the need to capture data for inbound 
cargo and stated that as of May 1, 2010, the agency issued changes to 
air carriers' standard security programs that require air carriers to 
report inbound cargo screening data to TSA. However, as noted in this 
report, these requirements apply to air carriers and the screening 
that they conduct and not to the screening conducted by other 
entities, such as foreign governments. Thus, TSA will continue to rely 
in part on estimates to report inbound cargo screening levels. We 
recognize that it may be challenging for TSA to obtain cargo screening 
data from foreign governments; however, the agency could require air 
carriers to report on cargo screening for all inbound cargo they 
transport, including the screening conducted by foreign governments or 
other entities. This would be similar to air carriers' domestic cargo 
screening reporting requirements which require air carriers to report 
on cargo that they screen as well as cargo screened by CCSFs. We 
continue to believe that it is important for TSA to obtain data for 
all screening conducted on inbound cargo so that it can provide 
assurance to Congress that this cargo is being screened in accordance 
with the 9/11 Commission Act screening mandate. TSA stated that 
verifying the accuracy of domestic screening data will continue to be 
a challenge because there is no means to cross-reference local 
screening logs--which include screening information on specific 
shipments--with screening reports submitted by air carriers to TSA 
that do not contain such information. We acknowledge TSA's potential 
challenges in cross-referencing screening logs with screening reports 
and have modified the report to reflect this challenge. However, as 
noted in this report, TSA could consider a quality review mechanism 
similar to the compliance measurement program used by CBP, which 
includes regular quality reviews to ensure accuracy in findings and 
management oversight to validate results. TSA could also develop 
another mechanism for verifying the accuracy of the screening data 
through random checks--other than those of the screening logs--or 
other practical means. Doing so would address the intent of our 
recommendation. Given that the agency uses these data to report to 
Congress its compliance with the screening mandate as it applies to 
domestic cargo, we continue to believe that verifying the accuracy of 
the screening data is important so that TSA will be better positioned 
to provide reasonable assurance that screening is being conducted at 
reported levels. 

TSA concurred with our third recommendation that TSA develop a plan 
for how and when the agency intends to require the screening of in-
transit cargo. TSA stated that the agency has implemented changes, 
effective August 1, 2010, that will require 100 percent of in-transit 
cargo to be screened unless it can otherwise be verified as screened. 
TSA's action is an important step toward addressing the potential 
security vulnerability associated with in-transit cargo and if 
implemented effectively, will address the intent of our 
recommendation. Because this is a significant change and potentially 
operationally challenging, it will be important to closely monitor the 
industry's understanding and implementation of this requirement to 
help ensure that 100 percent screening of in-transit cargo is being 
conducted. 

TSA did not concur with our fourth recommendation to develop a 
contingency plan for meeting the mandate as it applies to domestic 
cargo that considers alternatives to address potential CCSP 
participation shortfalls and screening technology limitations. TSA 
stated that a contingency plan is unnecessary since effective August 
1, 2010, 100 percent of domestic cargo transported on passenger 
aircraft will be required to be screened. The agency also stated that 
there is no feasible contingency plan that can be implemented by TSA 
that does not compromise security or create disparities in the 
availability of screening resources. However, the agency noted that 
several alternatives are available to and are currently being 
exercised by industry. The agency also stated that TSA developed the 
CCSP in collaboration with industry stakeholders to alleviate the 
burden on airlines to screen 100 percent of cargo while still meeting 
the mandate. We disagree that a contingency plan is unnecessary and 
unfeasible. As noted in this report, although TSA's approach would 
ensure that 100 percent of domestic cargo transported on passenger 
aircraft is screened, not transporting unscreened cargo could 
negatively affect the flow of commerce. In addition, while we 
recognize the CCSP as a positive and critical step toward achieving 
the screening mandate as it applies to domestic cargo, we continue to 
believe that there are feasible alternatives that TSA should consider 
to address potential CCSP participation shortfalls and screening 
technology limitations. Such alternatives discussed in this report 
include mandating CCSP participation for certain members of the air 
cargo supply chain and requiring the screening of some or all cargo 
before it is loaded onto ULD pallets and containers. Effective May 1, 
2010, TSA embraced one of the alternatives cited in this report by 
requiring freight forwarder CCSFs to screen all cargo before it is 
loaded onto ULD pallets and containers. Expanding this requirement to 
additional industry stakeholders could be a feasible alternative to 
address both CCSP participation shortfalls and screening technology 
limitations. Moreover, although many industry stakeholders may support 
the CCSP, key partners in the program--shippers--have not joined the 
program at the levels targeted by TSA, thus jeopardizing its success. 
Therefore, we continue to believe that it is prudent that TSA consider 
developing a contingency plan for meeting the air cargo screening 
mandate without disrupting the flow of commerce. 

Finally, in regard to our fifth recommendation that TSA develop a plan 
for how and when the agency intends to meet the mandate as it applies 
to inbound cargo, TSA concurred and stated that TSA is drafting 
milestones as part of a plan that will generally require air carriers 
to conduct 100 percent screening by a specific date. If implemented 
effectively, this plan will address the intent of our recommendation. 

In addition, DHS noted in its written comments that CCSFs have 
reported to TSA that they have the capacity to screen nearly the 
entire remaining unscreened cargo volume and that air carriers have 
reported to TSA that they do not anticipate any major disruptions to 
the transport of air cargo on August 2010. We were not able to verify 
these assertions because TSA did not provide supporting documentation. 
It is also important to note that having the potential capacity to 
screen air cargo does not ensure that this screening will take place 
when the 100 percent screening mandate goes into effect in August 2010. 

TSA also provided us with technical comments, which we considered and 
incorporated in the report where appropriate. 

As we agreed with your offices, unless you publicly announce the 
contents of this report earlier, we plan no further distribution until 
2 days from the report date. At that time, we will send copies to the 
Secretary of Homeland Security, interested congressional committees, 
and other interested parties. The report also will be available at no 
charge on the GAO Web site at [hyperlink, http://www.gao.gov].

Appendix I: Comments from the Department of Homeland Security: 

U.S. Department of Homeland Security: 
Washington, DC 20528: 

June 22, 2010: 

Mr. Steve Lord: 
Director, Homeland Security & Justice Issues: 
U.S. Government Accountability Office (GAO): 
441 G Street, NW: 
Washington, DC 20548: 

Dear Mr. Lord: 

Thank you for the opportunity to review and comment on GAO 10-446, the 
draft report titled: Aviation Security: Mt Has Made Progress But Faces 
Challenges in Meeting the Statutory Mandate for Screening Air Cargo on 
Passenger Aircraft. The Transportation Security Administration (TSA) 
appreciates the professionalism demonstrated by GAO's team members in 
conducting this difficult and broad-ranging review. TSA also values 
the investigative panel's review of this agency's efforts to enable 
the air cargo industry to achieve the 100 percent air cargo screening 
mandate of the Implementing Recommendations of the 9/11 Commission Act 
(9/11 Act). 

Since August 2007, when TSA was tasked with establishing a system to 
screen 100 percent of cargo transported on passenger aircraft, we have 
implemented a major new security program called the Certified Cargo 
Screening Program (CCSP), issued regulations and security program 
amendments to incrementally increase the level of screening of cargo 
transported on passenger aircraft departing U.S. locations, engaged in 
a broad-based campaign to educate industry on the 100 percent 
screening requirement and the benefits of CCSP participation, and 
significantly increased the number and types of technologies approved 
for screening air cargo to support the screening mandate. 

TSA has certified over 720 entities as Certified Cargo Screening 
Facilities (CCSFs) since the CCSP was initiated as a pilot program in 
2008, These entities currently are screening more than 40 percent of 
the cargo, by weight, carried on passenger aircraft departing U.S. 
airports. They have reported to TSA that they have the capacity to 
screen nearly the entire remaining unscreened volume as we approach 
the August 2010 deadline. Additionally, air carriers are continuing to 
invest in screening equipment, and have also reported that they do not 
anticipate any major disruptions. 

In October 2008, TSA began increasing the level of screening required 
on cargo transported on passenger aircraft in the United States by 
establishing a requirement to screen 100 percent of cargo transported 
on narrow body aircraft. This measure fully protects 96 percent of all 
domestic passenger aircraft flights, which carry more than 86
percent of all aircraft passengers in the United States. Subsequent 
updates to TSA security programs required 50 percent screening by 
February 1, 2009. and most recently, 75 percent screening by May 1, 
2010. Both levels have been successfully met by industry. 

TSA has reached out to more than 100,000 entities on the 100 percent 
screening requirement and the CCSP, working largely through major 
industry associations to engage stakeholders through webinars, 
conferences, newsletters, articles and advertisements in trade 
journals and the popular press. 

When the 9/11 Act was passed, no equipment had been tested or approved 
specifically for cargo screening. TSA has since created an approved 
technologies list that contains more than 50 technologies, including 
Advanced Technology (AT) X-ray capable of screening large cargo 
configurations, as well as Explosives Trace Detection (ETD), Explosive 
Detection Systems (EDS), and most recently Electromagnetic Devices 
(EMD). 

While industry has not yet achieved 100 percent screening for 
international inbound cargo due to the challenges of implementing a 
supply chain screening program internationally, TSA intends to require 
an increased level of screening for international inbound cargo as we 
continue to facilitate industry's achievement of 100 percent screening 
in the next few years. A combination of incremental increases in the 
screening requirements for carriers as well as recognition of foreign 
national cargo security programs, are key components of that strategy. 

TSA appreciates the work of GAO in its review of TSA Air Cargo 
Programs, and we will continue to address the issues identified by 
GAO. Our continued progress demonstrates our commitment to TSA's 
mission of securing our Nation's transportation systems and ensuring 
the freedom of movement of people and commerce. TSA's specific 
responses to GAO's recommendations are below. 

Recommendation 1: Establish milestones for the completion of TSA's 
staffing study. 

TSA concurs. As part of the Transportation Security Inspector (TSI) 
study, TSA is working to develop a demand model to be used to identify 
the number of TSIs needed at a particular location based on various 
factors, to include the number of regulated entities, such as CCSFs. 
This is expected to be completed in the Fail of 2010. TSA has already 
established an interim model that determines a ratio of inspectors to 
entities and that also considers other factors, such as cargo volume. 
TSA has already used the interim model in order to develop a plan for 
deployment of 50 TSI-Cargo (TSI-C) in fiscal year 2010. 

Recommendation 2: Develop a mechanism to verify the accuracy of all 
screening data, both self-reported domestic data and inbound cargo 
data, through random checks or other practical means. For Inbound 
cargo data, complete the agency's plan to obtain actual data, rather 
than estimates, on all inbound screening, including establishing 
timeframes and milestones for completion of the plan. 

TSA concurs in part. TSA concurs with the need to capture data for 
inbound cargo and as of May I, 2010, TSA issued changes to the 
standard security programs that require this data to be reported to 
TSA. However, the ability to verify the accuracy of screening data 
provided by regulated parties will continue to be a challenge. While 
TSI-C's can obtain specific screening logs for screening activity, 
there is currently no means to cross-reference local screening logs 
(which provide information as to how and by whom a particular shipment 
was screened) with carrier-level reports. Carrier reports themselves 
are a compilation of statistics provided by multiple locations. No 
specific shipment numbers are required as part of this process, and to 
add such a requirement would be a significant burden to industry. TSA 
will verify the accuracy of this data through random checks and 
inspections of screening logs. 

Recommendation 3: Develop a plan, with milestones, for how and when 
the agency intends to require the screening of in-transit cargo. 

TSA concurs. TSA has already taken significant steps to accomplish 
this objective, and has implemented changes to the Foreign Air Carrier 
Model Security Program and the U.S. Aircraft Operator Standard 
Security Program; effective August 1. 2010, 100 percent of all cargo 
transported on passenger aircraft from U.S. airports will be required 
to be screened. 

Recommendation 4: Develop a contingency plan for meeting the mandate 
as it applies to domestic cargo that considers alternatives to address 
potential CCSP participation shortfalls and screening technology 
limitations. 

TSA does not concur. Effective August 1, 2010, 100 percent of all 
cargo transported on passenger aircraft from U.S. airports will be 
required to be screened; to develop a contingency plan that suggests 
otherwise is unnecessary. TSA contends that there is no feasible 
contingency plan that can be implemented by TSA that does not 
compromise security or create disparities in the availability of 
screening resources among airports and/or commodity sectors. However, 
based on each entity's business model, there are alternatives that an 
entity can use including earlier shipment delivery times by air 
carriers for unscreened cargo, as well as the use of all cargo 
aircraft or surface alternatives. TSA has developed the CCSP in 
collaboration with industry stakeholders to alleviate the burden on 
airlines to screen 100 percent of cargo while still meeting this 
mandate. Industry supports this decision to screen cargo earlier in 
the supply chain before reaching the airlines. 

Recommendation 5: Develop a plan, with milestones, for how and when 
the agency intends to meet the mandate as it applies to inbound cargo. 

TSA concurs. TSA is drafting a set of milestones that will require all 
carriers to attain 100 percent screening by a specific date, unless 
other national cargo security programs are submitted, reviewed, and 
accepted as providing commensurate levels of security. We will be 
happy to share this plan with GAO when it is completed. 

Sincerely yours,

[8] There are about 450 commercial airports in the United States. TSA 
classifies airports into one of five categories (X, I, II, III, and 
IV) based on various factors, such as the total number of takeoffs and 
landings annually, the extent to which passengers are screened at the 
airport, and other special security considerations. In general, 
category X airports have the largest number of passenger boardings, 
and category IV airports have the smallest.

[18] All-cargo aircraft are aircraft that transport only cargo. 

[19] These cargo statistics were provided by TSA from the Bureau of 
Transportation Statistics. 

[20] H.R. Conf. Rep. No. 111-298, at 79 (2009). In fiscal year 2009, 
TSA allocated 85 proprietary canine teams--teams that are owned and 
operated full-time by TSA staff. TSA also has agreements with local 
law enforcement agencies, such as local police departments, for some 
of their canine teams to operate part-time in the air cargo 
environment. The transfer of 35 local law enforcement teams to TSA 
would increase the number of allocated TSA proprietary canine teams to 
120. TSA tests technologies in laboratory and operational 
environments, evaluates the performance and effectiveness of 
technology against preset standards, and upon successful completion of 
the assessments, deploys the technology at airports and air cargo 
facilities. 

[21] A weapon of mass destruction could include nuclear, biological, 
chemical, or radiological devices. 

[22] See 49 U.S.C. § 44901(g)(5). EDS uses computer-aided tomography X-
rays to examine objects inside baggage and identify the characteristic 
signatures of threat explosives. ETD requires human operators to 
collect samples of items to be screened with swabs, which are 
chemically analyzed to identify any traces of explosive material. 
Certified explosives detection canine teams have been evaluated by TSA 
and shown to effectively detect explosive devices. Physical search 
together with manifest verification entails comparisons between air 
waybills and cargo contents to ensure that the contents of the cargo 
shipment match the cargo identified in documents filed by the shipper. 

[23] TSA exempts some categories of air cargo from physical screening 
and requires alternative methods of screening, such as verifying 
shipper and cargo information and visually inspecting the cargo 
shipment, rather than opening the shipment and physically searching 
its contents or screening it with technology. TSA determines whether 
domestic cargo is subject to alternative methods of screening based on 
professional judgment and the results of the air cargo vulnerability 
assessments. For the purposes of this report, the phrase "exempt 
cargo" and the word "exemption" refer to cargo that is subject to such 
alternative screening measures. Narrow-body aircraft, such as Boeing 
737s and Airbus 320s, are defined by fuselage diameter, and most 
narrow-body aircraft have only one aisle. Narrow-body aircraft that 
fly in the United States do not carry ULDs that allow packages to be 
consolidated in a container or pallet. Wide-body aircraft are also 
defined by fuselage diameter and can carry ULDs. 

[24] According to statistics provided by TSA from the Bureau of 
Transportation Statistics, narrow-body aircraft make up 97 percent of 
passenger flights and transport more than 90 percent of passengers 
traveling on domestic passenger flights. 

[25] Details on TSA's screening exemptions are Sensitive Security 
Information and are not discussed in this report. 

[26] 49 C.F.R. §§ 1544.205(g)(1)(ii), 1546.205(g)(1)(ii). 

[27] The agency issued an interim order in December 2008 to allow 
shippers and other entities that were previously not regulated by TSA 
to screen, accept, and transfer air cargo. 

[28] 74 Fed. Reg. 47672, September 16, 2009. 

[29] A security threat assessment is a check of personnel against 
intelligence records and databases, including terrorist watch lists, 
and a limited immigration check, to verify that they do not pose a 
security threat. 

[30] Beginning in August 2010, at the 100 percent screening deadline, 
TSA officials told us that freight forwarder CCSFs will also be 
required to screen 100 percent of cargo being delivered to wide-body 
aircraft. 

[31] TSA refers to CCSP outreach coordinators as principal cargo 
security analysts. 

[32] Under the IFR, TSA plans to engage TSA-approved third-party firms 
to validate and certify CCSP applicants. TSA refers to these third- 
party validators as third-party assessment validation firms. According 
to TSA officials, CCSP outreach coordinators plan to manage the 
oversight and certification of the third-party validators. 

[33] The other industry association officials with whom we spoke did 
not comment on this issue. 

[34] GAO, Aviation Security: Preliminary Observations on TSA's 
Progress and Challenges in Meeting the Statutory Mandate for Screening 
Air Cargo on Passenger Aircraft, [hyperlink, 
http://www.gao.gov/products/GAO-09-422T] (Washington, D.C.: Mar. 18, 
2009). 

[35] Initially, the Air Cargo Screening Technology Pilot, or the 
Indirect Air Carrier technology pilot as it is named in the IFR, was 
limited to high-volume freight forwarders (i.e., freight forwarders 
processing at least 200 shipments annually per location that contain 
cargo consolidated from multiple shippers). However, in November 2008, 
TSA issued a second announcement seeking additional high-volume 
freight forwarders and independent cargo screening facilities to apply 
for the pilot. Moreover, entities that do not participate in the pilot 
will not receive TSA funding to purchase screening technology. 

[36] In December 2009, TSA extended the expiration date of the 
approved technologies to January 2012. For the purposes of this 
report, when discussing TSA's approved or qualified technology lists, 
X-ray refers to X-ray, advanced technology X-ray, or both. 

[37] The qualification process will also test future technologies not 
currently on the approved list once they mature and become approved. 

[38] TSA canine teams conduct primary and secondary screening of 
cargo. Primary screening counts toward meeting the air cargo screening 
mandate. Secondary screening provides spot checks of the screening 
already conducted by air carriers and CCSFs. TSA could not provide a 
breakdown of the 145 million pounds of cargo between primary and 
secondary screening. Based on 2008 cargo totals, 145 million pounds of 
cargo represents about 3 percent of domestic air cargo. 

[39] In fiscal year 2010, TSA projects a total of 805 canine teams in 
aviation, mass transit, and maritime systems. In the fiscal year 2011 
budget justification, TSA is requesting funding for an additional 275 
explosives detection canine teams to operate in the area of aviation 
security. 

[40] The DHS Appropriations Act, 2009, requires TSA to report to the 
House and Senate Appropriations Committees quarterly on the actual 
screening conducted, by airport and air carrier. See Pub. L. No. 110- 
329, § 515(d), 122 Stat. 3574, 3683. 

[41] Through an agreement with the House and Senate Appropriations 
Committees, TSA did not provide a 1st Quarter report. 

[42] Details on TSA's covert testing program are Sensitive Security 
Information and are not discussed in this report. 

[43] The CCSP allows air cargo industry stakeholders, such as an air 
cargo handling agent, to establish independent cargo screening 
facilities to provide screening services for shippers or freight 
forwarders that have not joined the program and do not want the air 
carriers to screen their cargo. These independent facilities screen 
cargo for a fee, according to CCSP guidelines. For the purposes of 
this report, we refer to independent cargo screening facilities as 
independent CCSFs. 

[44] The screening percentages in figure 4 have been rounded to the 
nearest percentage point. However, the actual percentages for March 
2010 sum to 68 percent. 

[45] According to TSA, as of March 2010, the agency had certified 397 
freight forwarder CCSFs, 143 shipper CCSFs, and 43 independent CCSFs 
out of an estimated population of 4,500 freight forwarders at 12,000 
locations and 15,000 shippers at 2 million locations. 

[46] A freight forwarder's size is determined by its annual sales. For 
example, a freight forwarder with $5 million or less in annual sales 
is considered to be small. 

[47] TSA's Regulatory Activities Plan establishes the minimum number 
of inspections, depending on airport size and other factors, TSIs are 
to conduct for each type of regulated entity. 

[48] During the 90-day nonenforcement period following certification-- 
during which CCSFs are not required to screen at mandated levels while 
they are developing their screening systems--TSA field offices may 
also require TSIs to visit CCSFs in their areas of responsibility to 
provide guidance on the TSA screening requirements that the entities 
must implement. TSA field offices are to schedule comprehensive 
inspections after the 90-day period expires. 

[49] According to TSA data, inspectors conducted 553 comprehensive 
inspections of CCSFs from February 1, 2009, through February 22, 2010, 
as the program was developing. Therefore, in the next year, inspectors 
will need to at least double their comprehensive inspections of CCSFs 
to reach the 1,166 target. Additional CCSFs and extra comprehensive 
inspections will further affect this increase. 

[50] We analyzed inspection data from February 1, 2009, through 
February 22, 2010. As of February 22, 2010, TSIs had performed 
inspections on 68 percent (392 of 576) of all certified CCSFs and 
approximately 77 percent (392 of 508) of those eligible for inspection 
that were beyond the 90-day nonenforcement period. We also calculated 
that as of February 22, 2010, 146 CCSFs had received two annual 
inspections. Because CCSFs are not eligible for inspection within 90 
days of certification, and some CCSFs had been certified for less than 
6 months and had not had their second required annual inspections, we 
calculated that 445 CCSFs were enrolled approximately 6 months prior 
to February 22, 2010, and at least 285 CCSFs were enrolled 9 months 
prior to February 22, 2010. 

[51] Details on the number and type of CCSF compliance inspection 
violations are Sensitive Security Information and are not discussed in 
this report.

[63] TSA requirements to screen inbound cargo will be discussed in 
further detail in a later section of this report. Details on TSA's 
screening exemptions are Sensitive Security Information and are not

screening exemptions, see GAO, Review of the Transportation Security 
Administration's Air Cargo Screening Exemptions Report, [hyperlink,

[65] [hyperlink, http://www.gao.gov/products/GAO-03-736]. 

[66] Details on TSA's screening requirements are Sensitive Security 
Information and are not discussed in this report. Prior to May 1, 
2010, TSA generally required air carriers to screen 50 percent of 
nonexempt inbound cargo transported on passenger aircraft and a 
certain percentage of all inbound cargo transported on passenger 
aircraft. 

[67] Banded cargo is cargo with heavy-duty metal, plastic, or nylon 
bands that secure all sides of the cargo shipment or secure the cargo 
shipment to a skid. While TSA officials could not provide a precise 
estimate of what percentage of inbound cargo this shrink-wrapped or 
banded cargo represents, about 96 percent of inbound cargo arrives in 
the United States on wide-body aircraft--the vast majority of which is 
transported on shrink-wrapped or banded skids. 

[68] According to statistics provided by TSA from the Bureau of 
Transportation Statistics, in 2008, narrow-body flights made up 69 
percent of inbound flights and transported 45 percent of inbound 
passengers. 

[69] TSA does not regulate foreign freight forwarders, or individuals 
or businesses that have their cargo shipped by air to the United 
States. The term harmonization is used to describe countries' efforts 
to coordinate their security practices to enhance security and 
increase efficiency by avoiding duplication of effort. Harmonization 
efforts can include countries mutually recognizing and accepting each 
other's existing practices--which could represent somewhat different 
approaches to achieve the same outcome--as well as working to develop 
mutually acceptable uniform standards. 

[70] ICAO is a specialized agency of the United Nations with the 
primary objective to provide for the safe, orderly, and efficient 
development of international civil aviation. 

[71] IATA is an industry association that represents about 230 air 
carriers constituting 93 percent of international scheduled air 
traffic. IATA's approach, called Secure Freight, is an attempt to 
create an air cargo industry comprising certified secure operators in 
secure supply chains operating to international cargo security 
standards recognized by relevant state authorities. A pilot of the 
Secure Freight program is scheduled to begin in the first half of 2010. 

[72] Air carriers departing from any foreign location in the Americas, 
including Mexico, Central America, and areas of South America north of 
the equator, must submit manifest information to CBP no later than the 
time of flight departure (the time at which wheels are up on the 
aircraft and the aircraft is en route directly to the United States). 
In the case of air carriers departing from any other foreign location, 
CBP requires that manifest information be submitted 4 hours prior to 
the flight's arrival in the United States. Unlike TSA's planned 
efforts to screen cargo prior to departure, CBP screens cargo once it 
enters the United States. 

[73] We have previously reported on TSA and CBP efforts regarding 
securing inbound cargo and recommended that the agencies improve 
coordination and information sharing. TSA and CBP's collaboration on 
ATS is a response to this recommendation. In addition, CBP created the 
International Air Cargo Strategic Plan in June 2007 to assist the 
agency in increasing aviation security related to inbound air cargo. 
For more information, see GAO, Aviation Security: Federal Efforts to 
Secure U.S.-Bound Air Cargo Are in the Early Stages and Could Be 
Strengthened, GAO-07-660 (Washington, D.C.: Apr. 30, 2007). 

[74] Details on TSA's screening requirements and exemptions are 
Sensitive Security Information and are not discussed in this report. 

[75] [hyperlink, http://www.gao.gov/products/GAO-07-660]. 

[76] See 49 U.S.C. §§ 44903, 44906; see also 49 C.F.R. §§ 1544.3, 
1546.3. Although TSA security requirements follow the ICAO standards 
and recommended practices, TSA may subject air carriers operating to, 
from, or within the United States to any requirements necessary and 
assess compliance with such requirements, as the interests of aviation 
and national security dictate. See 49 U.S.C. § 44906. 

[77] This includes both exempt and nonexempt cargo, under TSA's 
definitions. Since the screening of inbound cargo is conducted based 
on the standards of each individual country, it may not be conducted 
in accordance with TSA standards. For example, at least one country 
allows the use of large X-ray machines to inspect entire pallets of 
cargo that will be transported on passenger aircraft, without 
requiring the pallets to be broken down. In addition, two European 
countries use canines in a different manner than TSA to inspect air 
cargo for explosives. Specifically, these countries are using the 
Remote Air Sampling for Canine Olfaction technique, which involves the 
use of highly trained dogs to sniff air samples collected from air 
cargo or trucks through a specially designed filter. Such screening 
standards may produce different results from TSA's screening 
standards. See GAO-07-660 for more details. 

[78] According to TSA officials, the agency does not know the 
screening requirements for every country that transports air cargo 
into the United States. TSA assumes that other countries are in 
compliance, at a minimum, with TSA's regulation that a certain 
percentage of inbound air cargo be screened.
