STC - Data

  • Type of Aircraft: F 406

  • EASA STC: 10075453 (issued Feb 16, 2021)
  • FAA STC: --

  • Applicable Aircraft: ASI F406
  • Engines: Pratt & Whitney PT6A-112
  • Propeller: MTV-27-1-E-C-F-R(P)/CFR220-55( )

  • Advantages:
  • Best vibration damping characteristics for almost vibration free propeller operation
  • Bonded on wide chord nickel alloy leading edges for superior erosion protection of the blades
  • Smaller diameter of up to 16 cm (6 inch) compared to the original propeller, this means more ground clearance of about 8 cm (3 inch) for less FOD and also more clearance to the fuselage, therefore less cabin noise from the prop tips
  • Take-Off improvement up to 8%, so compared to the original AFM a higher safety for the calculated takeoff run
  • No propeller ADs
  • TBO 4500 hours or 6 years, whatever comes first, for low maintenance costs
  • No rpm restriction for the complete operational range
  • The long-time proven MT-Propeller natural composite blades provide significant inside and outside noise reduction
  • No life limitation and repairable in case of an FOD
  • Comply with the strict German noise regulations 2010 - „Landeplatz Lärmschutz Verordnung“ for unrestricted airport operations in Germany and other European Countries
