MT-Propeller Entwicklung GmbH has received the Venezuelan letter of acceptance of the FAA STC SA03487AT for the Piper PA-42-1000 (Cheyenne 400LS) equipped the Quiet Fan Jet composite propeller MTV-27-1-E-C-F-R(G)/CFR(L)250-103.

This installation is already supplemental type certified by FAA, EASA and ANAC Brazil. 75 percent of the world wide PA42-1000 fleet is already converted.

MT-Propeller President Gerd Muehlbauer says, that the installation features the following advantages:

- Take-off distance over 50 ft obstacle reduced by approx. 5% (SL, ISA, MTOW)

- Enhanced climb by approximately 3% (SL, ISA conditions, MTOW) increasing by altitude

- Enhanced cruising speeds by approximately 5 kts + (ISA, FL250, 11500 lbs GW)

- Approximately 52 lbs less total weight than the original propellers 

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.

MT-Propeller is the world leading natural composite propeller manufacturer with 30 propeller models from two-blade to six-blade hydraulically controlled variable pitch propellers for engines producing up to 5000hp, and two-blade to four-blade electrically controlled variable pitch propellers 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 certifications requirements they are also supplemental type certified on Part 25 aircraft.
