4. Background and Changes.

A. Background: The DOI OAS is responsible for the calculation of the Department of the Interior aircraft accident rate. An accurate accident rate requires an accurate reporting of all flight time accumulated by aircraft that are under the operational control of the Department. This includes flights that may be of no cost to the Department. However, there are times when Interior employees fly on aircraft that are not under the operational control of the Department. If an accident occurred during one of these flights, it would not be chargeable to the Department. Flight time from flights that are not under the operational control of the Department should not be reported.

B. Changes: Replace 351 DM 4.F.(1) with the following language: Reporting Requirements. All use of aircraft under the operational control of the Department shall be reported by the using bureau, utilizing an Aircraft Use Report (Form OAS-23). Refer to 14CFR 1.1, “General definitions." If the flight is at no cost to DOI, "Not for Payment Purposes" shall be noted in the "Other Charges/Credits" section of the OAS-23.
