PC-12 upgrade specialist Super Legacy XP has become the first PC-12 operator worldwide to install and obtain full certification for the MT47 seven blade propeller on its Super Legacy demonstration aircraft.

The process culminated in flight performance tests conducted in Germany and high-altitude take-offs at Europe's uppermost airports, Samedan in Switzerland and Courchevel Altiport, with its runway ‘resembling a ski jump’. The latest propeller from MT, combined with the Super Legacy speed cowling, demonstrated significant performance improvements in takeoff roll, accelerate stop distance, rate of climb and cruise speed. A complete change of harmonics also brings additional cabin comfort to the aircraft.

The heart of the Super Legacy concept is a Finnoff upgrade that replaces the standard PT6A-67B engine with a new PT6A-67P power plant, warrantied for seven years by P&W. Adding a further 200hp to a lighter weight airframe, the demonstrator outperforms the PC12-NG in several key parameters.

London based Super Legacy XP Limited is the European, Middle East and Africa distributor for the individual upgrade components, engine, propeller, speed cowl and Skandia cabin noise reduction system. With over 50 upgrades performed mainly in the US, the company is on track to upgrade and modify four PC-12 aircraft to Super Legacy standard for EMEA delivery during 2021 and 2022.

Director Stephen Williams says: “I'm delighted with the results of our project with MT and the installation of the Silent 7 propeller. When coupled with a price tag for a finished aircraft almost $2million lower than the latest factory PC-12, and a much shorter waiting list, the Super Legacy offers a sensible choice for aircraft buyers seeking both performance and value. Our upgrade components also offer compelling options for existing PC-12 owners of all variants including the NG who want improved performance from their personal or corporate aircraft.”

Martin Albrecht, VP at MT Propeller adds: “It became clear when our static thrust tests went off the scale of our meter that the additional blades of the Silent 7 were going to make a significant uplift in performance. This was proven in flight and the reduction in tip speed and vibration now confirms a significant improvement in noise and comfort; hence our label the Silent 7.”
