Honeywell continues to hone turboprop engine for 50th anniversary

This year Honeywell marks the 50th anniversary of its TPE331 turboprop engine, which powers single-engine aircraft around the world. Designed from scratch for the military, the engine was developed for multiple applications across military and general aviation. With more than 1,000 shaft horsepower, it is the most cost-effective and powerful engine in its class with the lowest cost of ownership. In addition, its simple single-shaft design provides an instant throttle response and best-in-class hot-and-high performance.

Since the first commercial version of the engine received its type certification from the Federal Aviation Administration in 1965, the series now includes 18 models and 106 configurations. More than 13,500 TPE331 engines have been delivered to date, logging more than 122 million hours of flight time. It is one of the most reliable and proven turboprop engines, known for its shorter takeoffs, improved fuel efficiency and lower operating costs compared with competing turboprop engines. The TPE331 has also been awarded the highest overall average score in a product support survey by Aviation International News magazine since 2010 and was named Best New Product by Twin Commander in 2013.

Honeywell continues to work with airplane manufacturers across the aerospace industry to ensure the TPE331 will meet the needs of the aviation community for the next 50 years.
