MT Propeller has received an FAA STC to install its Quiet Fan Jet 5-blade propeller on Beech King Air 300s and 350s.
The STC is for King Airs powered by Pratt & Whitney PT6A-60A/-67A engines and a maximum takeoff weight up to 17,636 pounds.
According to MT-Propeller President Gerd Muehlbauer, the new prop:
- Provides an 8% improvement in takeoff and climb and an additional 4 to 5 knots in cruise
- Has no propeller speed restrictions on the ground while operating in low idle
- Has more ground clearance for less FOD
- Has FOD repairable blades
- Provides “significant” cabin noise and vibration reduction
- Has no life limitation
