Brand new project - Piper Meridian converted to a PT6A-135A turbine
Having ideas how to make aircraft quieter and more efficient, MT-Propeller took the Piper Meridian as a new program, replacing the original PT6A-42A engine with a PT6A-135A engine. Initial flight test data show basically the same performance, reduced noise with a maximum propeller RPM of 1900 and an increased range of:
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
The flight tests were performed with a 5-bladed Quiet Fan Jet MTV-27 Propeller, the propeller is already certified on the original Piper Meridian and can be used also – if already installed – on this conversion.
Maintenance cost will be reduced by installing the new engine.
Changing the engine family from the mid-size category to the small-size, makes an impressive difference for the operating cost.
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. EASA certification is planned for second quarter of 2024 with the FAA STC following.
