The Piper Cheyenne group of turboprop corporate flying machine is focused around the famous Navajo and Chieftain cylinder twins.

In spite of the fact that the first Cheyenne was not conveyed until mid 1974, work on a turboprop variant of the Pressurized Navajo goes back very nearly 10 years prior to the mid 1960s. The model of the Cheyenne flew shockingly on August 29 1969, however Piper needed to upgrade the flight controls to handle the expanded loads on the airframe because of the higher rates. Creation conveyances were further postponed because of flooding at Piper's Lock Haven plant in June 1972.

Certificate had been conceded on May 3 1972, while the first generation air ship (controlled by 462kw/620shp Pt6a-28s) first flew on October 22 1973.

Flautist presented the lower controlled (373kw/500shp Pt6a-11s) and less costly Cheyenne I in 1978, and renamed the first Cheyenne the Cheyenne II. Refinements to the Cheyenne I made in 1983, including more power at elevation, overhauled cowlings and inside, brought about the Cheyenne IA.

In the interim the extended Cheyenne IIXL had been presented in 1979. Contrasted and the standard length Cheyennes, the IIXL was 61cm (2ft) more extended, offered an additional lodge window on the left side, 180kg (400lb) expanded max takeoff weight and 560kw (750shp) Pt6a-135s. An enhanced Iixla was arranged, yet did not enter creation.
