MT-Propeller has received the EASA STC 10054488 Rev. 1 for the Cessna 208 Caravan powered by the Honeywell TPE331-12JR propeller turbine with the QFJ five-blade MTV-27-1-E-C-F-R(G)/CFRL270-66 propeller.

With this revision the Cessna 208 and 208B with the five-blade MT-Propeller are now certified for a power rating up to 950shp. The revision of the FAA STC is in progress.

MT-Propeller vice president Martin Albrecht says, that the installation of the five-blade MT-Prope on the Cessna 208 features the following advantages:

- 60 % vibration reduction on aircraft fuselage

- Approximately14 kg (31 lbs) less weight than the original propeller

- Ground roll reduced by 10% approximately 50 m (164 ft)

- Climb improved by 5-8%

- Unbeatable aesthetic ramp appeal

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

Due to its smaller diameter the MT-Propeller for the Cessna 208 has more ground clearance for less blade tip erosion and FODs compared to the original propeller.

The long time proven MT-Propeller natural composite blades provide significant inside and outside noise reduction. They have no life limitation and are repairable in case of a 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 seven-blade hydraulically controlled variable pitch propellers for engines producing up to 5,000hp, 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.
