Former Texas Air Beech 99 N22AT joined the Colgan Airways fleet in April 1971. A year later it was registered N99CA. Sold when the airline merged with Presidential Airways in 1988, the aircraft, maintaining the N99CA registration, would fly with Chaparral Airlines on a short lease (August 1988 - January 1989). After subsequent leases to Alpine Air Express, the airline would buy the aircraft in 1994. It was later stored at Provo, UT and the registration cancelled in 2018.
