New prop approved for Diamond DA42

By General Aviation News Staff · December 10, 2021 ·

MT-Propeller has received an FAA STC for the installation of a new scimitar design 3-blade hydraulically actuated constant speed propeller on Diamond DA42s powered by two Technify Motors GmbH TAE 125-01, TAE 125-02-99, or TAE 125-02-114 engines or Austro Engine GmbH 4E-B.

With this upgrade the original DA42s can feature the same modern propellers as those on the latest models from the factory, MT-Propeller officials said.

According to MT-Propeller Vice President Martin Albrecht, features include:

  • Vibration damping characteristics for almost vibration free propeller operation
  • No engine modifications
  • Ground roll and takeoff distance over 50 foot obstacle reduced by approximately 131 feet
  • Climb performance improved by 10%.
  • 2 to 3 knots more speed (for Technify engines).

The MT-Propeller natural composite blades have no life limitation and are repairable in case of a FOD, company officials add.

The installation is already certified by EASA and TCCA Canada.
