MT-Propeller Entwicklung GmbH has received the validation of SCT Mexico for the EASA STC EASA.A.S.03217 for the Quiet Fan Jet composite propeller MTV-27-1-N-C-F-R(P)/CFR260-65a on the Pilatus PC-12 powered by P&WC PT6A-67B or PT6A-67P.

This installation ist already supplemental type certified by EASA, FAA and Transport Canada.
MT-Propeller President Gerd Muehlbauer says, that the installation of the 5-bladed MT-Propeller features the following advantages:
  • – Ground roll distance reduced by approx. 15%
  • – Take-off distance over 50 ft obstacle reduced by approx. 5%
  • – Climb performance improved
  • – Cruise performance improved by up to 5 kts versus the PC-12 POH/AFM
    – More ground clearance for less FODs
  • – Approx. 4 lbs less weight than the original metal propeller
  • – Aircraft noise level is about 4 dB(A) less than with the original metal propeller
  • – Cabin noise is reduced by 6 to 7 dB(A) depending on location
No engine modification is necessary.
The MT-Propeller natural composite blades provide significant inside and outside noise reduction. They have no life limitation and are repairable in case of an FOD. They also provide best vibration damping characteristics for almost vibration free propeller operation and have bonded on nickel alloy leading edges for superior erosion protection of the blades.

SupportsMT-Propeller is the world leading natural composite propeller manufacturer with 30 certified propeller models from 2-blade to 6-blade hydraulically controlled variable pitch propeller, for engines producing up to 5000hp, and 2-blade to 4-blade electrically controlled variable pitch propeller, for engines producing up to 350hp as well as two blade fixed pitch propellers.

The high performance, light weight and durable MT-Propellers can be used on aircraft with piston engines and propeller turbines, as well as on airships, wind tunnels or hovercraft. MT-Propellers can be developed for nearly every aircraft type from motor gliders to regional airliners. Fulfilling the highest certification requirements they are also supplemental type certified on Part 25 aircraft.
MT-Propeller is holder of over 210 STCs worldwide and OEM supplier for more than 90% of the European Aircraft Industry as well as 30% of the US Aircraft Industry. 20,000 propeller systems with more than 69,000 blades are in service. 130 Million fleet hours where already performed on MT-Propellers. 36 years ago, the first MT-Propeller was shipped.
