Highlights

The Department of the Interior has cut its aviation accident rate in half since 1975--from 18.8 accidents to 8.7 per 100,000 flight hours. The department's lower accident rate can be attributed to the implementation of a standard aviation operating policy and to aviation safety standards that exceed the Federal Aviation Administration's requirements. The Office of Aircraft Services (OAS) has not fully recovered aviation program costs. From fiscal years 1999 to 2000, OAS has charged bureaus about $4 million less than actual costs, representing an undercharge of about two percent. OAS set rates that were based on flight hour projections of actual usage that turned out to be low, and OAS did not include all the cost elements that needed to be considered. Periodic monitoring of the rates and actual costs would ensure that all costs are recovered. OAS has yet to develop a more cost-effective approach for using aircraft. To cut costs, OAS has reduced its staffing levels by 24 percent since 1992.

Recommendations

Recommendations for Executive Action

Agency Affected Recommendation Status
Department of the Interior To ensure that all program costs are fully recovered and to improve the rate-setting process, the Secretary of the Department of the Interior should direct OAS to obtain forecasts of future usage from the bureaus and use these forecasts, as well as other relevant information, to set rates.
Closed – Implemented
In August 2003, OAS implemented a new planning process to determine the projected flight hours to be used for rate setting purposes. OAS and the DOI Bureaus established a goal for actual aircraft use to be within plus or minus 10 percent of the projected use. Variances of greater than 10 percent will be analyzed and futures aircraft rates adjusted as needed.
Department of the Interior To ensure that all program costs are fully recovered and to improve the rate-setting process, the Secretary of the Department of the Interior should direct OAS and the bureaus, upon completion of the rate-setting process and calculation of associated payments, to determine whether the rates recovered all costs and, if not, whether adjustments in the process used to calculate the rates are necessary.
Closed – Implemented
Actual aircraft costs exceeding more than plus or minus 10 percent of the estimated costs will be reviewed to establish the relative accuracy of cost and inflation data used in the rate computation and to identify factors contributing to the variance.
Department of the Interior The Secretary of the Department of the Interior should instruct the directors of OAS and of each bureau to improve scheduling and use of aircraft and establish performance measures to monitor and assess progress.
Closed – Implemented
OAS published a strategic plan to address GAO's recommendations. This plan includes performance goals and measures related to aircraft scheduling and use. The plan will be implemented during 2004 and 2005.
