Pratt & Whitney Canada is now providing its PT6C-67D powerplant for the Bell UH-1H helicopter engine conversion program under an STC held by Alaska's Temsco Helicopters. “We have developed a strong working relationship with Temsco and we will put the full resources of P&WC at the disposal of UH-1H operators who opt for the engine conversion," said P&WC vice president of marketing Irene Makris.

The PT6C-67D engine's advantages include a 20 percent increase in takeoff power, a 25 percent increase in maximum continuous power, a 25 percent increase in payload range, and a 25 percent reduction in fuel consumption, P&WC said. "Each factory-new engine is equipped with an electronic engine control for precise and fast rotor governing with a hydro-mechanical back-up feature that provides for safe engine control and ease of helicopter operation," the OEM said. "It also records and downloads engine performance, life usage and exceedances metrics from the engine’s data control unit."

The engine carries a factory warranty of 1,500 hours or four years. Maintenance intervals are set at 2,000 hours for hot section inspection and 4,000 for overhaul, according to P&WC.
