MT-Propeller Entwicklung GmbH has received the Letter of Acceptance of the FAA STC #SA03525NY for the next generation 5-blade scimitar composite propeller on the Beech King Air 300/350 Series powered by the P&WC PT6A-60A engines.
The installation is also certified by EASA, Transport Canada and ANAC Brazil.
The new 5-blade MT-Propellers provide a performance improvement of approximately eight percent in takeoff and climb and four to five knots in cruise on this aircraft type. There are no propeller speed restrictions on ground while operating in low idle. The ITTs are lower during start-up for less engine wear. Due to the smaller diameter of the 5-blade construction, it has more ground clearance for less FODs.
The MTV-27 Propeller has also bonded on nickel alloy leading edges for superior erosion protection of the blades. Natural composite blades provide best vibration damping characteristics for almost vibration free propeller operation and a significant cabin noise reduction. These special blades are repairable in case of FOD.
MT-Propellers have no life limitation, their construction provides maximum durability and reliability and they are suitable for all weather operation.
All models comply with the strict German noise regulations 2010 – “Landeplatz Lärmschutz Verordnung” for unrestricted airport operations in Germany and other European countries.
