Piper PA-31T Cheyenne

The Piper Cheyenne family of turboprop corporate aircraft is based on the popular Navajo and Chieftain piston twins. The Piper PA-31T Cheyenne is a turboprop development of the earlier PA-31P Pressurized Navajo. The Cheyenne series of business aircraft was one of the most successful Piper products. The development of the Cheyenne began in the mid-1960s when Piper made a decision to redesign the „Navajo” to use turbines instead of piston engines.  The resulting PA-31T Cheyenne was introduced in 1974.

Originally, the aircraft was an upgraded version of the Pressurized Navajo equipped with two Pratt & Whitney Canada PT6A-28 turboprop engines. Later, the aircraft was further refined and developed, including aerodynamic improvements and fuselage extensions. The PA-31T led to the development of the PA-42 Cheyenne III and IV.
