The TPE331 is not your ordinary engine, with the mechanics to operate more efficiently at higher altitudes and shorter runways. With more than 14,000 TPE331 engines flying around the world today, it’s no wonder why it’s been the leading choice for aircraft owners for more than 50 years.

  • Faster throttle response - single shaft design
  • Better fuel efficiency – higher pressure ratio
  • Lower cost of ownership - Conklin & de Decker
  • Longer maintenance intervals – no need for special FAA program
  • Quieter flyover - meets new German Airfield Noise Protection Order
  • Higher gearbox rating
  • Single exhaust
  • Simpler to operate - automatic one-button starting, single red line, torque and temperature limiting
  • No inlet particle separator - less hardware and much less performance penalty in icing conditions
  • Clean installation – access to all LRUs for maintainability


Seeing is believing. That’s why we think you should see the savings for yourself. Your turboprop engine is an investment, not something you should have to worry about replacing every time the going gets tough. Get an engine that was designed to withstand the harshest flying environments and stop spending money on an engine that you’ll have to replace the next time you blink your eyes.
