Piper PA-42-1000 Cheyenne 400
The Piper PA-42 Cheyenne 400 was the largest, fastest, and most powerful member of Piper's Cheyenne twin-turboprop family, fitted with high-revving Garrett engines that gave it near-jet cruise speeds. Its pressurised cabin and strong climb performance let it compete for some of the same missions as light jets of its era, at a turboprop's lower fuel cost. Its distinctive high-pitched engine sound, a hallmark of the Garrett TPE331, set it apart from the Pratt & Whitney PT6-powered turboprops common elsewhere in the Cheyenne lineup. Comparatively few were built, making it a rare sight next to Piper's smaller, more common Cheyennes.
Did you know?
Garrett TPE331 engines, like the Cheyenne 400's, are notoriously sensitive to starting technique — a mishandled start can ruin one within seconds.
