EASA STC for Piper Meridian with PT6A-135A engine
On the 1st day of the AERO, the MT-Propeller EASA STC for the installation of the PT6A-135A engine in the Piper Meridian was officially handed over by Mr Marco Capaccio, Small Aircraft, Balloons & Airships Section Manager European Union Aviation Safety Agency, to Josef Eberl, MT-Propeller Chief Engineer and Test Pilot, and Martin Albrecht, MT-Propeller General Manager and Test Pilot.
Being the leader in propeller design and the only company that holds more than 220 STCs to install the most modern MT-Propellers with up to 7 blades, the engineers and test pilots decided to take the next step and not only certify a more efficient propeller, but also combine it with a more efficient engine. So they took the Piper Meridian and replaced the original PT6A-42A engine with a PT6A-135A engine.

The advantages of the engine replacement are:
More Efficiency
RANGE
Max. range with max fuel (ISA, MTOW, no wind, one pilot, 45 min fuel reserve)
203 KTAS cruise speed: 1340NM (2479km) @ 30000ft
203 KTAS cruise speed: 1290NM (2387km) @ 28000ft
240 KTAS cruise speed: 1160NM (2146km) @ 28000ft
258 KTAS cruise speed: 960NM (1776km) @ 25000ft
Reduction of Maintenance cost
Changing the engine family from the mid-size to the small-size category, makes an impressive difference in operating costs.
Direct cost per mileage will be similar to the PA46-350P Lycoming-powered Mirage, but with a top speed of up to 260 KTAS @ 30,000 ft.
Noise reduction
The new engine has a speed of 1900 rpm compared to the original speed of 2000 rpm. The certified outside noise is reduced from the original 74,9 db(A) to 66,9 db(A) for 1.999 kg. The inside noise has also been reduced.
The 5-bladed propeller is mandatory for this STC, but in case the 5-blade Quiet Fan Jet MTV-27 propeller is already installed, it can also be used on this conversion.

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.
MT-Propeller is holder of over 220 STCs worldwide and OEM supplier for more than 90% of the European Aircraft Industry as well as 30% of the US Aircraft Industry. More than 30 000 propeller systems with more than 100 000 blades are in service.
180 Million fleet hours where already performed on MT-Propellers.
With the longest industry TBO of 4500 hours or 6 years for the 5-bladed turbo prop MT-Propeller has proven the reliability over years.
A factory certified network of 62 service centers, provides best service and maintenance all over the world.
