5-blade prop OK’d for Socata TBM

By Janice Wood · June 21, 2011 ·

MT-Propeller Entwicklung GmbH has received an FAA STC for the next generation 5-blade scimitar composite propeller MTV-27-1-E-C-F-R(P)/CFR225-55f on the Socata Model TBM700 A, B, C1, C2, N with the P&WC PT6A-64, -66D engine.

The new STC provides increased performance (5% improved takeoff and climb, 3-5 kts cruise with 1800 rpm), and is suitable for all weather operations, according to company officials.

According to company officials, the new prop also:

  • Reduces the weight by approximately 7 lbs compared with the original metal propeller
  • Provides a cooler ITT on ground with condition lever at low and high idle position
  • Has no propeller speed restrictions on ground while operating in low idle
  • Gives more ground clearance for less FODs.
  • Provides cabin noise and vibration reduction
  • The natural composite blades have no life limitation and can be repaired even in case of a FOD.
