MT composite propeller cleared for Rotax-powered Diamonds

MT-Propeller received a supplemental type certificate from the FAA for the installation of its MTV-21-A/170-05 two-blade, constant-speed propeller on the Diamond DA20-A1 and HOAC DV20 Katana aircraft powered by the Rotax 912 S3 engine.

The company said the propeller will allow the aircraft to comply with enhanced German noise regulations in addition to damping vibration for smoother operation. The company’s natural composite blades are known for durability, and have no life limitation. The latest Diamond installation had already been approved by the European Union Aviation Safety Agency and Transport Canada Civil Aviation.

MT manufactures 30 certified propeller models ranging from two-blade to seven-blade versions with hydraulically controlled variable pitch for engines up to 5,000 horsepower, and models with two to four blades with electrically controlled pitch meant for engines producing up to 350 horsepower. The company manufactures propellers for piston and turbine-powered airplanes ranging from motorgliders to regional airliners, as well as airships, hovercraft, and wind tunnels.

The company said it holds more than 220 STCs and is an original equipment manufacturer supplier to more than 90 percent of the European aircraft industry and 30 percent of the U.S. aircraft industry.
