Pratt & Whitney Canada PW100/PW127

Few numbers matter more to an operator than what hangs on the wing or sits in the nacelle. The Pratt & Whitney Canada PW100/PW127, from Pratt & Whitney Canada, is a turboprop for propeller-driven aircraft flying regional, utility and corporate missions producing 2,750 shp of shaft power, in service since 1983.

The Pratt & Whitney Canada PW100/PW127 is a family of turboprop engines designed for regional airliners and multi-engine turboprops in the 2,000–5,000 shp class. The PW127 variant produces 2,750 shp and is optimized for the ATR 42 and ATR 72 regional turboprop aircraft, offering a high propulsive efficiency and low fuel consumption. The engine family features FADEC on later variants and has accumulated over 100 million flight hours. Its applications include the ATR 42, ATR 72, Bombardier Dash 8 Q400 and CASA CN-235 — and an engine's installed base matters commercially, because a widely flown type means deeper parts availability, more shop options and better residual liquidity.

Turboprop economics revolve around the overhaul interval (TBO), hot-section inspections and whether the engine is enrolled on an hourly maintenance programme — an enrolled engine with documented cycles is worth materially more than an identical unit without them.undefined
