The Piper PA-31T Cheyenne is a turboprop development of the earlier PA-31P Pressurized Navajo.

Development[edit]

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.
