MT-Propeller has received FAA STC for the Quiet Fan Jet MTV composite propeller on the Quest Kodiak 100 series powered by the Pratt & Whitney PT6A-34. This installation is already certified by EASA and TCCA.
VP Martin Albrecht says that the installation feature the following advantages: take-off improvement by 20 per cent; no propeller speed restrictions on ground while operating in low idle; lower ITTs during start-up for less engine wear; significant cabin noise up to five dB(A) and vibration reduction; unbeatable aesthetic ramp appeal; compliance with the strict 2010 Landeplatz Lärmschutz Verordnung German noise regulations for unrestricted airport operations in Germany and other European countries; and maximum rpm reduction to 2000 rpm with increased torque for 750 shp.
Due to the smaller diameter of the MT-Propeller compared to the original metal propeller the Kodiak 100 series has more ground clearance for less blade tip erosion and FODs. The MT blades also provide significant inside and outside noise reduction. They have no life limitation and are repairable in case of a FOD, and low vibration damping characteristics for almost vibration free propeller operation and have bonded on nickel alloy leading edges for superior erosion protection of the blades.
