PC12 - The World's first fully certified MT47 "Silent 7" upgrade.

PC12 upgrade specialist Super Legacy XP Limited are the first Pilatus PC12 operator worldwide to install and obtain full certification for the MT47 Seven Blade propeller on their PC12 Super Legacy demonstration aircraft.

This process culminated in-flight performance tests conducted in Germany and high-altitude take-off’s 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 Super Legacy.

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 7 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 $2million 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, VP 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.”

Super Legacy XP Limited are distributors for Finnoff Aviation Products, MT Propeller Company, American Aviation Speed Cowl, Skandia Sound Systems, and Garmin Avionics.


The Pilatus PC-12 Super Legacy XP aircraft provides a value driven alternative to the purchase of a factory new aircraft: extra performance, comfort and safety but lower capital and lower absolute depreciation than a new aircraft.

Formed in 2018 Super Legacy XP Limited is based at Denham and Biggin Hill airports in the UK, and Cannes in the South of France. As distributors for Finnoff Aviation Products, MT Propeller Company, American Aviation Speed Cowl, Skandia Sound Systems, and Garmin Avionics, Super Legacy works with these partners to assemble and deliver customized PC12 aircraft. The company also supplies the upgrade components to existing Pilatus PC12 owners wishing to upgrade their existing aircraft.

The new EASA certified Flight Manual Supplements of the upgraded Super Legacy XP enable added power, capability, and luxury to the PC-12-45/47 Legacy series aircraft as a turn-key solution. These enhancements to power plant, propeller, cabin soundproofing and interior detail combine to provide superior levels of performance. Coupled with familiar (Garmin) avionics and a seven-year Pratt & Whitney extended power plant warranty the Super Legacy XP provides outstanding value to both private owners and commercial charter operators.
