LAS VEGAS—Pratt & Whitney Canada has introduced what it says is the most powerful and fuel efficient engine on the general aviation market.

The company’s new PT6A-140A turboprop engine and the PT6A-140AG variant deliver 15 per cent more power with 5 per cent fewer fuel consumption.

“Today’s announcement demonstrates our ability to continuously innovate and raise the bar with the PT6A family to make the world’s best engines even better,” Denis Parisien, vice-president of General Aviation at P&WC, said. “There are more than 70 PT6A engine models used for over 125 different aircraft applications around the globe – a testament to the PT6A’s unmatched versatility, performance and reliability.”

The new engine has no mandatory requirements for warm-up or cool-down, something that allows operators to maximize their productivity and efficiency, P&WC, said.

“No one understands the needs of general aviation better than we do,” Parisien added. “We built the industry with the PT6A turboprop engine more than five decades ago and we’ve never stopped innovating since. These two engines are a demonstration of the advancements we’ve made and our focus on delivering the best engines for customers and operators.”

The two new engines are optimized for “hot and high” environments, packing 867 mechanical shaft horsepower and 1,075 thermal mechanical shaft horsepower. They offer full-load take off at maximum power at 111 F, or 44 C.

The company also said its modular design and externally-mounted fuel nozzles make it the easiest engine on the market to access and maintain.

“Simple routine engine inspections can be done while still on-wing, in the field or in the hangar, eliminating surprises, reducing costs and providing peace of mind. More time on-wing and a predictable and planned maintenance environment mean more revenue for operators,” the company said.
