STC - Data


  • Type of Aircraft: Beech 1900 series

  • EASA STC: 10070090 issued June 03, 2019
  • FAA STC: i.p.
  • TCCA Canada: Letter of Acceptance of the EASA STC

  • Applicable Aircraft: Beechcraft A100/200/300/1900
    Model: 1900, 1900C, 1900D
  • Engines: PT6A-65B and -67D
  • Propeller: MTV-27-1-()-C-F-R(P)/CFR260-65k

  • Advantages:
  • Best vibration damping characteristics
    for almost vibration free propeller operations!
  • Bonded on wide chord nickel alloy leading edges for superior erosion protection of the blades
  • Smaller diameter of about 8 inch compared to the original 4-blade propeller, this means more ground clearance of about 4 inch for less FOD and also more clearance to the fuselage, therefore less cabin noise from the prop tips
  • Take-Off improved by 4% , so compared to the original AFM a higher safety for the calculated take-off run
  • No propeller ADs
  • Propeller noise reduction by up to 5 dB(A)
  • TBO 4000 hours or 6 years, whatever comes first, for low maintenance costs
  • No intermediate inspections are needed between the TBO which requires the propeller removal
  • Reduced costs for spare parts, like blades and lower overhaul costs, for the complete propeller assembly
  • 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.
