MT-Propeller Entwicklung GmbH has received a letter of acceptance of the FAA STC #SA03525NY for the next generation five-blade scimitar composite propeller MTV-27-1-E-C-F-R(P)/CFR260-65b on the Beech King Air 300/350 series (Beech 300, 300LW, B300, B300C) powered by P&WC PT6A-60A engines.

The installation is also certified by EASA, Transport Canada and ANAC Brazil.

MT-Propeller president Gerd Muehlbauer says, this propeller installation is a great improvement to the Beech King Air 300/350 series.

The new five-blade MT-Propellers provide a performance improvement of approximately 8% in take-off and climb and 4-5 kts 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 five-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 a FOD.

MT-Propellers have no life limitation and their construction provides maximum durability and reliability and they are suitable for all weather operation.

The multiple blade design has an unbeatable esthetic ramp appeal and the best weight to price ration in the industry.

All models comply with the strict German 2010 "Landeplatz Lärmschutz Verordnung" noise regulations for unrestricted airport operations in Germany and other European countries.

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. 

MT-Propeller is the holder of over 210 STCs worldwide and the OEM supplier for more than 90% of the European aircraft industry as well as 30% of the US aircraft industry. Over 18,000 propeller systems with more than 68,000 blades are in service.

130 million fleet hours have already been performed on MT-Propellers. The first MT-Propeller was shipped 35 years ago.
