Piper PA-41 Cheyenne 400LS
Piper designed this Cheyenne model in the early 1980s to compete with the pro-posed King Air 350, but ran out of money for development and certified it to lower weight and speed than its ultimate capability. Only 45 were made between 1984 and 1991, although a handful more came out of the Piper factory for Lufthansa trainers.
The PA-41 differs from other, Chieftain-based, Cheyennes with a new airframe and pair of 1000 shp Garrett TPE 331-14-801 big block engines. Counter-rotating Dowty Rotol composite propellers of 106 in diameter transfer the power to the air, giving the 400LS more speed and range than some small jets, with those capabilities being given more weight than large numbers of passengers.
Engines: 2 x Garrett TPE 331-14-801, 1000 shp
