EASA STC for Beech 1900 series with 5-blade MT prop
MT Propeller
Atting, June 2019 - MT-Propeller Entwicklung GmbH has received the EASA STC 10070090 for the Quiet Fan Jet composite propeller MTV-27-1-()-C-F-R(P)/CFR260-65k on the Beech Model no. 1900, 1900C and 1900D powered by two Pratt & Whitney PT6A-65B or -67D Propeller Turbines. The FAA STC has now also been obtained.
MT-Propeller has received the EASA STC for a five blade Quiet Fan Jet composite propeller on the Beech 1900 series of aircraft.
MT-Propeller Vice President Martin Albrecht says, that the installation feature the following advantages compared to the original 4-blade propellers:
- The 5-blade MT-Propeller has a smaller diameter of about 8 inch compared to the original 4-blade propeller, this means more ground clearance of about 4 inch for less FOD and also more clearance to the fuselage, therefore less cabin noise from the prop tips
- Take-Off of the Beech 1900 is improved by 4%, so compared to the original AFM a higher safety for the calculated take-off run
- The MTV-27 has no propeller ADs
- The 5-blade MT-Propeller reduces the propeller noise by up to 5 dB(A)
- The MTV-27 has bonded on wide chord nickel alloy leading edges for superior erosion protection of the blades
- TBO for the MT-Propeller is 4000 hours or 6 years, whatever comes first, for low maintenance costs
- No intermediate inspections are needed between the TBO which requires the propeller removal
- Reduced costs for spare parts, like blades and lower overhaul costs, for the complete propeller assembly
- No rpm restriction for the complete operational range
- 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 an FOD. They also provide best vibration damping characteristics for almost vibration free propeller operation.
About MT-Propeller
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.
