FAA STC for 7-blade MTV-37 on Piper PA46-600TP and PA46-701TP
MT-Propeller Entwicklung GmbH received the FAA STC SA12438IB for the installation of the "Silent 7" 7-blade propeller MTV-37-1-E-C-F-R(P)/CFR205-353( ) on the Piper PA46-600TP and Piper PA46-701TP powered by the Pratt & Whitney propeller turbines PT6A-42A in PA-46-600TP and PT6A-52 in PA-46-701TP.
This installation is already supplemental type certified by EASA STC 10089486.
MT-Propeller Vice President Martin Albrecht says that the installation features the following advantages:
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.
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.
No active AD, this is a safety record no other manufacturer has achieved so far.
The MT-Propeller fleet is approaching a total of 135 000+ 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 holder of 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.
A factory certified network of 62 service centers provides best service and maintenance all over the world.
This installation is already supplemental type certified by EASA STC 10089486.
MT-Propeller Vice President Martin Albrecht says that the installation features the following advantages:
- Shorter take-off distance by approx. -10 % (SL, ISA conditions)
- Enhanced climb performance by approx. 5 % (SL, ISA conditions)
- Cruise performance increased by 2-3 KTAS
- Significant inside and outside noise reductions
- Comply with the strict German noise regulations 2010 - „Landeplatz Lärmschutz Verordnung“ for unrestricted airport operations in Germany and other European Countries!
