AFAC Mexico Authorizes MT-Propeller’s 5-blade Propeller for King Air 90 Models

MT-Propeller received the AFAC Mexico validation IA-SA00148IB of the EASA STC #10046759 Rev.2 for the installation of the next generation Quiet Fan Jet 5-blade scimitar composite propeller for the Beechcraft King Air B90, E90, C90, C90A, C90GT, C90GTi models. It also includes those with the Blackhawk Conversion powered by PT6A-20, -20A, -21, -27, -28, -135A engines and other TC/STC approved PT6A series engines which do not exceed the propeller TCDS.
This installation is already certified by the FAA, EASA, Transport Canada, DGCA India and ANAC Brazil.

  • According to MT-Propeller Vice President Martin Albrecht the propeller installation on the King Air 90 provides the following advantages:
  • Best vibration damping characteristics for almost vibration free propeller operations
  • Bonded on nickel alloy leading edge for superior erosion protection of the blades
  • General performance improvement of 5% on takeoff and climb, 2-3 knots cruise with 1,900 rpm
  • No propeller speed restrictions on ground while operating in low idle
  • More ground clearance for less FODs
  • Lower ITTs during startup for less engine wear
  • Unbeatable esthetic ramp appeal
  • Significant cabin noise and vibration reduction

All models comply with the strict German noise regulations 2010 – “Landing Site Noise Abatement Ordinance” for unrestricted airport operations in Germany and other European countries.

Fulfilling the highest certification requirements they are also supplemental type certified on Part 25 aircraft.

With the longest industry TBO of 4,500 hours or six years for the 5-bladed turboprop MT-Propeller has proven the reliability over years. The high technology natural composite blades have no life limitation and can be repaired even in case of FOD.
