The Piper PA-31T Cheyenne is a twin-engine 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.

Accidents and incidents
[edit]- On April 12, 2015, four people were killed when their Piper PA-31T Cheyenne reported a distress call for smoke in the aircraft upon approaching Fort Lauderdale for landing after taking off from Orlando. The aircraft crashed into a wildlife preserve just short of the airport, causing a large fire killing all on board.[4]
- On April 17, 2017, a Piper PA-31T Cheyenne crashed in a parking lot of a Lidl supermarket in Tires, Portugal. The pilot and one person on the ground were killed in the crash.[5]
- On December 28, 2019, a Piper PA-31T Cheyenne crashed shortly after takeoff, approximately one nautical mile from LFT. The pilot was able to avoid an apartment complex but the aircraft struck a vehicle and a USPS branch on its way down. Four passengers and the pilot were killed on impact. One passenger and one person on the ground were seriously injured, while two additional people on the ground suffered minor injuries.[6] The NTSB released a preliminary report and is investigating the accident.[7]
- On April 20, 2020, a Piper PA-31T Cheyenne N926K crashed just west of Billings Logan International Airport in a local gun and archery establishment. The sole occupant, the pilot, received fatal injuries due to smoke inhalation. A probable cause by some locals favored a possible engine failure upon initial climbout.[8][9]
- On October 22, 2025, a Piper PA-31T Cheyenne crashed shortly after takeoff from Paramillo Airport, Táchira, Venezuela. The two occupants died in the explosion. [10]
