Overview
Program history
Piper developed the Cheyenne 400LS from the PT6-powered Cheyenne III family, within a product line that began with the company’s first turbine-aircraft certification in 1972. Its certified designation is PA-42-1000. The Cheyenne range evolved through differing cabin lengths, powerplants and equipment, so performance and loading limits depend on the exact model and installation.
