MT-Propeller Entwicklung has received the FAA STC SA00037IB for the three-blade MTV-12-B-C-F/CF(L)183-59( ) propeller on the Piper PA-34-200 Seneca I powered by Lycoming IO-360-C1E6 and LIO-360-C1E6 engines. This installation is already certified by EASA STC 10076572.

Vice president Martin Albrecht says the installation features the best vibration damping characteristics for almost vibration-free propeller operations; bonded on stainless steel leading edge for best erosion protection of the blades; take off distance slightly improved; up to 20 lbs less weight than the original propeller; unlimited blade life; increased ground clearance for less blade tip erosion; and no rpm vibration restriction.
