What GAO Found

Federally owned aircraft are operated by agencies to fulfill their diverse missions. As of July 2016, 11 federal agencies owned 924 aircraft, excluding those that are loaned/leased/provided to other entities. This inventory included:

  • 495 airplanes,
  • 414 helicopters,
  • 14 unmanned aircraft systems (commonly known as drones), and
  • 1 glider.

Of the 11 civilian agencies, the Department of State owned the most aircraft (248), and the National Science Foundation owned the least (3). Agencies reported spending approximately $661 million to use and maintain owned aircraft in fiscal year 2015. Agencies reported using aircraft for a variety of purposes, including law enforcement, scientific research, firefighting, and other activities.

Of the 924 owned aircraft, 88 were non-operational in July 2016. Agencies consider an aircraft to be non-operational when it cannot economically be returned to airworthiness. Non-operational aircraft can be used for parts, put on display, or be destroyed, among other things. Aircraft that were owned and operational as of July 2016 were used for an average of 275 flight hours in fiscal year 2015. These aircraft ranged from 0 flight hours to 1,279 in fiscal year 2015. Flight hours is the most common metric for aircraft use, although some aircraft also report alert or research and development hours. Agencies reported spending approximately $652 million in fiscal year 2015 to use and maintain aircraft that were owned and operational as of July 2016. Agencies typically report their costs in four cost categories: maintenance, overhead, fuel/oil, and crew. Agencies do not report the cost of depreciation.

GAO provided a draft of this report to the Departments of Agriculture, Commerce, Energy, Homeland Security, Interior, Justice, State, and Transportation; the National Aeronautics and Space Administration; the National Science Foundation; and the Tennessee Valley Authority for comment. We received technical comments from the Departments of Agriculture and Justice, which we incorporated as appropriate.

Why GAO Did This Study

This report summarizes recent information on the composition and characteristics of federally owned civilian aircraft. GAO reviewed and analyzed both published and unpublished Federal Aviation Interactive Reporting System (FAIRS) data that agencies reported to GSA. To provide historical perspective on aircraft costs and inventory, we reviewed and summarized data published by GSA in FAIRS reports from FY2011 through FY2015. To provide more detailed and recent information, we analyzed unpublished FAIRS data on individual aircraft that were in agencies' reported inventories as of July 2016. In addition to analyzing FAIRS reports and data, we also reviewed agencies' Inspectors General (IG) reports from FY2011 through June 2016; examined relevant regulations and guidance on the acquisition of civilian federal aircraft; and requested information on aircraft missions from the 11 civilian agencies that own aircraft.
