Proven engine family has provided reliable power for agricultural aviation and firefighting missions for nearly 50 years

RENO, Nev., Nov. 19, 2025 /PRNewswire/ -- The global fleet of Pratt & Whitney Canada PT6A turboprop engines designed specifically for agricultural aviation and firefighting missions have flown more than 1 million hours this year. Since the first PT6A engine model for the aerial application industry was certified in 1977, Pratt & Whitney Canada has developed eight different models, with close to 5,000 engines produced to date. Pratt & Whitney is an RTX (NYSE: RTX) business.

The eight PT6A engine models power aircraft manufactured by Air Tractor and Thrush Aircraft. These single-engine aircraft are used around the world, particularly in the United States, Canada, Brazil, Europe, and Australia, to support a safe, affordable and abundant food supply; control health-threatening pests; promote healthy forests; and fight forest fires.

"Pratt & Whitney Canada has long supported the aerial application industry and the critical missions it serves," says Cedric Gauthier, vice president, Sales and Marketing, General Aviation, Pratt & Whitney Canada. "For nearly 50 years, we have worked in lockstep with airframers, maintainers, aircraft owners and pilots as they pursue missions that help feed the world and protect property from the ever-increasing threat of forest fires. Surpassing more than 1 million hours of flight this year speaks to the unique attributes of the PT6A engine, including its performance, innovation and reliability."

The PT6 engine family remains the benchmark in general aviation, having powered more than 155 different aircraft types and amassing over 500 million flying hours since its introduction in 1963. Today's PT6 engines are up to four times more powerful than the original model, with a 50% improved power-to-weight ratio and up to 20% better specific fuel consumption.

Another Pratt & Whitney Canada engine family, the PW100, powers De Havilland of Canada's iconic DHC-415 and new DHC-515 waterbombers that are instrumental in assisting firefighting missions around the globe, including the California wildfires that occurred earlier this year. Around the globe Pratt & Whitney Canada powered helicopters also help combat forest fires.
