MT-Propeller has received an FAA STC for its 3-blade prop on the Piper PA-34-200 Seneca I.
The prop, which weighs about 20 pounds less than the original propeller, is approved for Senecas powered by Lycoming IO-360-C1E6 and LIO-360-C1E6 engines.
According to MT-Propeller Vice President Martin Albrecht, the prop features:
- Bonded on stainless steel leading edge for erosion protection of the blades
- A slightly improved takeoff distance
- Increased ground clearance for less blade tip erosion
- Best vibration damping characteristics for almost vibration free propeller operations
- No rpm vibration restriction
- Unlimited blade life
