Propellor upgrade for PC12 boosts performance
PC12 upgrade specialist Super Legacy XP Limited is the first Pilatus PC12 operator worldwide to install and obtain full certification for the MT47 Seven Blade propeller (the Slient 7) on its PC12 Super Legacy demonstration aircraft
This 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.
The heart of the Super Legacy concept is a Finnoff upgrade that replaces the standard PT6A-67B engine with a new 67P power plant, warrantied for seven years by P&W. Adding a further 200hp to a lighter weight airframe, the Super Legacy 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, Super Legacy XP is on track to upgrade and modify four PC12 aircraft to Super Legacy standard for EMEA delivery during 2021/2.
Super Legacy Director Stephen Williams said: “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 US$2-million lower than the latest factory PC12, 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 PC12 owners of all variants, including the NG, who want improved performance from their personal or corporate aircraft.”
Martin Albrecht, Vice-President at MT Propeller Company and champion aerobatic test pilot commented: “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’.”
Enhancing the performance and versatility of aircraft is key to improving their longevity in the market. In May this year, the PC12’s capabilities were further enhanced when ASU obtained an STC for night vision imaging system use on the plane.
