The Office of Aviation Services (OAS) is an internal aviation department of the U.S. Department of the Interior (DOI). Established in 1973, its mission is to raise safety standards, increase efficiency, and promote economical operation of aircraft activities within the Department. OAS manages, maintains, and operates DOI's government-owned and commercially contracted aircraft fleet, including Uncrewed Aircraft Systems (UAS), to support various DOI missions and trains bureau personnel. This is not a public flight school or aircraft rental service.
