MT-Propeller has received an EASA STC for a 3-blade natural composite propeller on the Piper PA-28R series, powered by Lycoming IO-360-B, IO-360-C or IO-360-C engines.
The FAA STC is in progress.
According to MT-Propeller President Gerd Muehlbauer, the installation features:
- Up to 10 kg lighter than the original propeller
- Cooler CHTs by up to 35°C (95°F)
- Unlimited blade life
MT-Propeller manufactures 30 certified propeller models from 2-blade to 7-blade hydraulically controlled variable pitch propellers for engines producing up to 5000 hp, and 2-blade to 4-blade electrically controlled variable pitch propeller for engines producing up to 350 hp, as well as two blade fixed pitch propellers.
I was talking to an MT representative at Oshkosh last year about an electric constant speed prop for a Grumman Cheetah with a Lycoming O 320 engine.
He told me that it could be done with a field approval. If that is correct can you give me a price for this conversion and what the system entails.
Nice job MT.
