MT-Propeller Entwicklung GmbH has yet received the EASA STC #10043965 for the next generation 3-blade scimitar composite propeller MTV-9-B/200-58 on the Gipps Aero GA8 optional also with the weight increase to 1905kg MTOW, powered by a Lycoming I0-540-K1A5 engine. This STC ist also valid for the GA8 TC320 and the FAA STC is already in progress. 

MT-Propeller Vice President Martin Albrecht says that the installation of the 3-blade MTV-9 Propeller on the GA8 provides a general performance improvement. 

Flight tests have shown, that the take-off distance is enhanced by approx. 2 %, climb performance by approx. 3 % and the cruise performance is enhanced by 2 to 3 kts. All tests are performed with MTOW at SL, ISA conditions.

The MTV-9 for the GA8 has approx. 25lbs less weight, compared to the original 3-blade propeller.

Natural composite blades have excellent vibration damping characteristics for almost vibration free propeller operation and a significant inside and outside noise reduction. 

Bonded on stainless steel leading edges provide best erosion protection of the blades.

These special blades are repairable in case of a FOD.

MT-Propellers have no life limitation and their construction provides maximum durability and reliability and they are suitable for all weather operation.
