Pratt & Whitney Canada PT6C

First run in 1994, the Pratt & Whitney Canada PT6C is a turboshaft from Pratt & Whitney Canada built for helicopters, where power-to-weight and hot-and-high margins decide real capability, producing 1,800 shp of shaft power. It is a mature, widely supported design.

The Pratt & Whitney Canada PT6C is a turboshaft engine variant of the PT6 family, specifically designed for medium and heavy helicopters where high power output and reliability are essential. The PT6C-67 variant powers the Sikorsky S-92 helicopter, delivering 1,800 shp with FADEC and automated health monitoring features. Like all PT6 engines, it uses a reverse-flow annular combustor and a free power turbine for independent rotor speed control. Its applications include the Sikorsky S-92 and AgustaWestland AW139 — and an engine's installed base matters commercially, because a widely flown type means deeper parts availability, more shop options and better residual liquidity.

For turboshafts, buyers weigh power margin at the temperatures and altitudes they actually operate, the cost and interval of module overhauls, and the health-monitoring data available — trend data materially de-risks a purchase. Condition, documentation and programme status are what separate two otherwise identical engines — request a quote above and we'll set out the options by condition: new, overhauled, serviceable or core.
