MT-Propeller has received an FAA STC for its scimitar four-blade composite propeller on the Aerostar PA-60-600, -601, -601P, -602P, and PA-60-700P powered by Lycoming IO-540-A, IO-540-S, and TIO-540-U engines.
According to MT-Propeller Vice President Martin Albrecht, advantages of the new prop include:
- Shorter takeoff distance
- Enhanced climb by approximately 3% to 5%
- Cruise performance increased by approximately 3 to 5 knots
- A weight savings of approximately 40 pounds over the original propeller
- No airframe resonance with low engine RPM.
