Adam Aircraft Industries was a company that existed from 1998 until it went bankrupt in 2008. It produced one aircraft, the A500 twin-engine turboprop business aircraft. Seven A500s were made. The A500 design was based on a Burt Rutan prototype, the M-309, which was intended to explore exceptionally safe business aircraft using the configuration of placing two engines on the center line of the aircraft, one pushing from the back and the other pulling from the front. AAI’s principals were George F. Adam and John C. Knudsen; it was located in the Denver area.
The prototype that served as the scaled-down inspiration for the A500 series is now displayed at Wings Over the Rockies Air & Space Museum.
