STC - Data


  • Type of Aircraft: SA26-AT

  • EASA: EASA.A.S.03603 (issued Oct 02, 2008)
  • FAA: SA02782CH (issued May 14, 2009)

  • Applicable Aircraft: M7 Aerospace LP Model SA26-AT
    (Merlin 2B)
  • Engines: TPE331-1-151G, TPE331-1-151G
    modified per FAA STC SE383CH
  • Propeller: MTV-27-1-E-C-F-R(G)/CFR210-58d

  • Advantages:
  • Best vibration damping characteristics
  • Bonded on nickel alloy leading edge for best erosion
    protection of the blades
  • No engine modifications (no cam or beta tube change)
  • Reduced ground roll and take-off distance
  • Improved two engine and single engine climb performance
  • Cruise performance slightly improved by up to 5 kts
  • Approx. 16 lbs less weight than the original metal propellers
  • More ground clearance for less FODs
  • Significant inside and outside noise reductions
  • Aircraft noise level is about 5 dB(A) less than
    with the original metal propellers
  • Cabin noise is reduced by 3 to 4 dB(A) depending on location
  • Unlimited blade life
  • FOD repairable blades
