EASA STC for 4-blade MTV-14 MT-Propeller on Cirrus SR22T
MT-Propeller Entwicklung GmbH received the EASA STC 10089430 for the installation of the scimitar 4-blade MTV-14-D/195-30( ) propeller on the Cirrus Model SR22T powered by a Lycoming TSIO-550-K engine. As an option fluid De-Ice Boots can be installed.
The 3400 lbs Version is already certified by EASA STC 10038566 R6. The FAA and TCCA STCs are in progress.
MT-Propeller Vice President Martin Albrecht says that the installation features the following advantages:
MT-Propeller is the world leading natural composite propeller manufacturer with 30 certified propeller models from 2-blade to 7-blade hydraulically controlled variable pitch propeller, for engines producing up to 5000hp, and 2-blade to 4-blade electrically controlled variable pitch propeller, 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 and hovercraft. MT-Propellers can be developed for nearly every aircraft type from motor gliders to regional airliners.
Fulfilling the highest certification requirements, they are also supplemental type certified on Part 25 aircraft.
No active AD, this is a safety record no other manufacturer has achieved so far.
The MT-Propeller fleet is approaching a total of 125 000+ propeller blades on 34 500+ propeller systems in operation and can look back on accumulated 200 million flight hours in over 45 years.
With the best damage tolerance and repairability, MT-Propeller has the lowest operational cost of any certified composite propeller manufacturer.
MT-Propeller is holding more than 230 STCs worldwide and OEM supplier for more than 90% of the European Aircraft Industry as well as 55% of the US Aircraft Industry.
With the longest industry TBO of 4500 hours or 6 years for the 5-bladed turbo prop, MT-Propeller has proven reliability for years.

MT-Propeller Vice President Martin Albrecht says that the installation features the following advantages:
- Turbine smooth, vibration free propeller operations
- Replaceable Nickel leading edge for best erosion protection of the blades
- Improved engine cooling
- Enhanced climb performance and shorter take-off distance
- Increased static thrust
- Enhanced cruise performance
- Unlimited blade life, Lower cost overhaul and No AD’s
- The 3.600 and 3.400 lbs versions comply with the strict German Noise Regulation “Landeplatz Lärmschutz Verordnung” for unrestricted airport operations in Germany and other European Countries ().
