MT-Propeller Entwicklung GmbH has received EASA STC 10062000 for the new scimitar four-blade composite propeller MTV-14-B-C-F/CF(L)188-30g on the Aerostar PA-60-600, -601, -601P, -602P and PA-60-700P equipped with Lycoming IO-540-S1A5-MM, IO-540-AA1A5-MM and (L)TIO-540-U2A engines. The FAA STC is in progress.

MT-Propeller vice president Martin Albrecht says, that the installation features the following advantages:

- Shorter take-off distance

- Enhanced climb by approx. 3% to 5% (SL, ISA conditions)

- Cruise performance increased by approx. 3 to 5 kts (MTOW, ISA conditions)

- Approx. 40 lbs less weight than the original propellers

- No airframe resonance with low engine rpm.

The MT-Propeller natural composite blades provide significant inside and outside noise reduction. They have no life limitation and are repairable in case of an FOD.

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

MT-Propeller is the world leading natural composite propeller manufacturer with 30 propeller models from two-blade to six-blade hydraulically controlled variable pitch propellers for engines producing up to 5000hp, and two-blade to four-blade electrically controlled variable pitch propellers for engines producing up to 350hp as well as two blade fixed pitch propellers.
