Scimitar Composite Prop Manufactured By MT-Propeller

EASA has granted an STC (#10054490) to MT-Propeller for the next generation 3-blade scimitar composite propeller MTV-9-B/198-52 on the Rockwell Commander 114, 114A, 114B, 114TC powered by the Lycoming engines IO-540-T4A5D, IO-540-T4B5D, IO-540-T4B5 and TIO-540-AG1A. An FAA STC is in the works, according to the company.

According to the company's certification flight tests, the new 3-blade propeller installation reduces ground roll & takeoff distance over 50 ft obstacle by 98 ft and increases climb performance slightly.

No engine modification is nessecary for the installation of the MTV-9.

The company says testing shows the prop is very smooth in cruise and there is no speed penalty. The propeller weighs about 17.6 lbs less than the original 3-blade metal propeller.

MT-Propeller says its natural composite blades provide significant inside and outside noise reduction for a "jetlike" vibration and noise signature. They have no life limitation and are repairable.

They also provide best vibration damping characteristics for almost vibration free propeller operation and have bonded on stainless steel leading edges for superior erosion protection of the blades, the company says.
