Department of the Interior: Office of Aircraft Services and Bureaus Can More Fully Recover and Further Reduce Aviation Program Costs (17-APR-02, GAO-02-460). The Department of the Interior's aviation accident rate has been cut in half since 1975, from 18.8 accident to 8.7 per 100,000 flight hours between fiscal years 1975 and 2000. The department's reduced 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. The undercharge resulted from rates OAS set that were based on flight hour projections of actual usage that turned out to be low. Further, 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 not yet developed a more cost-effective approach for using aircraft, which could potentially lead to additional cost savings. To cut costs, OAS has reduced its staffing levels by 24 percent since 1992. https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-02-460/html/GAOREPORTS-GAO-02-460.htm GAO-02-460 https://www.govinfo.gov/app/details/GAOREPORTS-GAO-02-460 Other Written Product GAO-02-460; Department of the Interior: Office of Aircraft Services and Bureaus Can More Fully Recover and Further Reduce Aviation Program Costs; Aviation Cost analysis Cost control Safety Cessna 206 Amphibian Aircraft De Havilland DHC-2T Beaver Aircraft Civil Service Retirement System Title 43 Section 1467 43 U.S.C. 1467
