OAS Mission Statement

The Office Aviation Services (formerly the NBC-Aviation Management Directorate (AMD)) was established by the Secretary of the Interior on July 1, 1973 to "Raise the safety standards, increase the efficiency, and promote the economical operation of aircraft activities in the Department of the Interior." In this capacity, OAS serves both the Secretary and the nine DOI bureaus as primary customers. Leveraging its resident wealth of Office of Aviation Services experience and expertise and in keeping with the Departmental management excellence initiatives and the President’s Management Agenda, OAS also serves the aviation needs of numerous other Federal agencies. OAS’s mission is to provide our customers with higher quality (Better), more cost-wise (Cheaper) aviation services at lower cycle times (Faster) that result in increased operational performance and fewer losses (Safer) than any one of them can provide for themselves. A component of the DOI Office of the Secretary (OS), OAS is led by a Director who reports to the Deputy Assistant Secretary for Public Safety, Resource Protection and Emergency Services (PRE).
