MT-Propeller Says The New Prop Improves Takeoff, Climb, And Cruise Performance

The FAA has issued an STC to MT-Propeller Entwicklung for installation of its next generation 5-blade scimitar composite propeller on Cessna 425 aircraft powered by the P&WC PT6A-112 engines. The prop complies with strict German noise regulations for unrestricted airport operations in Germany and other European countries.

In a news release, the company says the propeller installation provides vibration damping characteristics for "almost vibration free" propeller operations. It has bonded on nickel alloy leading edges for for superior erosion protection of the blades, and is estimated to provide a general performance improvement of 5% on take-off & climb and 3 kts cruise at 1900 rpm.

The prop also has no life limitation and has FOD repairable blades.
