MT-Propeller has received STC from the FAA for the installation of the four-blade natural composite propeller MTV-14-D-C-F/CF188-30() on Cessna 414A series aircraft with or without RAM IV and VII powered by the TSIO-520-N or -NB or TSIO-520-NB engines. This installation is also supplemental type certified by EASA.

MT-Propeller vice president Martin Albrecht says the installation has the following advantages: “Shorter take-off distance by approximately six per cent; enhanced climb by between five and eight per cent; cruise performance increased by approximately three to five kts, depending on altitude and power setting; and approximately 20 lbs less weight than the original propellers.”

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