Originally designed in 1959 and certified in 1965, the TPE331 was our first turboprop engine. Developed for multiple applications within military, regional airline, agricultural and general aviation aircraft, the series now includes 18 engine models and 106 configurations.
Today, with more than 13,000 engines delivered and more than 122 million hours of flight time, the TPE331 is one of the most reliable and proven turboprop engines in the world.
Pilots flying TPE331-powered aircraft enjoy exceptional horsepower response and best-in-class fuel economy. Additional TPE331 benefits include quick throttle response for shorter take-offs, good power-to-weight ratio and long maintenance intervals.
Several conversion programs are available to enable aircraft to:
Take off shorter
Cruise farther or faster
Improve fuel efficiency
Lower overall operating costs
