Finnoff Aviation, at NBAA 2022, celebrated the 100th re-engining of a Pilatus PC-12 aircraft. Â Their re-engining program for older model PC-12 aircraft replaces the existing PT6 with a new Pratt & Whitney Canada PT-6A-67P engine, providing improved thrust, increased speed, and better time to climb for the aircraft. Â Chris Finnoff and his team briefed the media at NBAA 2022, and a video of the press briefing follows:
The PC-12 has been a phenomenal success since its introduction in 1991, with multiple upgrades over its life. The first three series of the PC-12, 41, 45, and 47 have the PT6A-67B series engine.  The current NGX or 47E series has the PT6A-67P engine.  The addition of the PT6A-67P brings older PC-12s up to the performance of today’s models, with substantially improved time to climb (without a steep climb) and higher airspeeds. Chris Finnoff and his team are experts in the PC-12 market and have found that many buyers find that acquiring a used PC12 from the 41, 45, or 47 models and re-engining it with the Finnoff STC is a way to gain the performance of a new aircraft at a lower cost.
Finnoff also has an STC with MT Propellers for a 5-blade prop and also offers a 7-blade alternative to improve the performance of legacy PC-12s. In addition, a new accessory gearbox with two 300-amp generators is included. Â Finnoff Aviation has always been “all things PC-12” and recognized experts in aircraft. Â They obtained the STC in 2012 when a few legacy PC-12 engines were nearing overhaul but found customers who appreciated the performance increase. Â Today, as many customers consider whether to overhaul or gain improved performance from replacement engines, their retrofit business is robust, as evidenced by the completion of the 100th conversion. Â The engines come with a factory 5-year or 2,500-hour warranty, which Finnoff Aviation extends to 7 years or 2,500 hours. Â
Finnoff also provides additional options, including a ThrutSense Autothrottle from IS&S, a single or dual TB40 Lithium-ion battery system, a second lead-acid battery, an installation of the P&WC FAST data acquisition and analysis package, an electrical system upgrade, and MT 5 or 7 blade propellers.
