MT three-blade Seneca prop is cleared by EASA
MT-Propeller is a leading natural composite propeller manufacturer with 30 propeller models from two-blade to seven-blade hydraulically controlled variable pitch propellers. Its latest offering can propel the Piper Seneca.
The Seneca is afforded corrosion protection by the three-blade propeller.

MT-Propeller has received EASA STC for the three-blade MTV-12 prop on the PA-34-200 Seneca I powered by Lycoming IO-360-C1E6 or LIO-360-C1E6 engines. The FAA STC is in progress.

MT-Propeller VP Martin Albrecht says that the installation features the following advantages: best vibration damping characteristics for almost vibration free propeller operations; bonded on stainless steel leading edge for best erosion protection of the blades; takeoff 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.

MT-Propeller is a leading natural composite propeller manufacturer with 30 propeller models from two-blade to seven-blade hydraulically controlled variable pitch propellers for engines producing up to 5,000hp, 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.

The high performance, light weight and durable MT-Propellers can be used on aircraft with piston engines and propeller turbines, as well as on airships, wind tunnels or hovercraft. MT propellers can be developed for nearly every aircraft type from motor gliders to regional airliners.

Fulfilling the highest certifications requirements, they are also supplemental type certified on Part 25 aircraft.

MT-Propeller is the holder of over 220 STCs worldwide and the OEM supplier for more than 90 per cent of the European aircraft industry as well as 30 per cent of the US aircraft industry. More than 25,000 propeller systems with over 87,000 blades are in service, and 180 million fleet hours have been performed on MT-Propellers.

MT-Propeller has also received EASA STC for the three-blade MTV-12 propeller on the Piper PA-23-235, PA-E23-250 and PA-23-250 powered by Lycoming O-540-A-series, Lycoming IO-540-C-series, Lycoming TIO-540-C-series (PA-23-250, PA-E23-250) or Lycoming O-540-B-series (PA-23-235) engines. Again, the FAA STC is in progress.
