Finnoff Aviation Products is celebrating its 100th delivery of a Pratt & Whitney PT6A-67P engine upgrade for the legacy Pilatus PC-12, the company announced on Monday at NBAA-BACE 2022. 

While the engines are designed and built by Pratt & Whitney Canada (P&WC), Finnoff Aviation (Booth 4185) holds the FAA supplemental type certificate (STC) for the engine upgrade for legacy Pilatus PC-12s. The turboprop single entered service in the 1990s and was originally powered by the P&WC PT6A-67B engine. 

Introduced in 2006, the PC-12NG aircraft comes equipped with the more powerful PT6A-67P engine. Upgrading the engines on legacy PC-12s brings the older aircraft’s performance parameters up to the standards of the newer model. 

The -67P engine provides a 20 percent increase in horsepower during climb and allows the aircraft to travel 15 knots faster during cruise. It also generates about 40 percent more electrical power.

Finnoff, which specializes in PC-12 upgrades, started working on the PT6A-67P upgrade for legacy PC-12s in 2008. In 2012, the company received an STC for the upgrade and completed its first installation.

Other PC-12 upgrades offered by Finnoff include MT-5 and MT-7 propellers, ThrustSense autothrottle installations, P&WC's flight acquisition storage and transmission installations, electrical system upgrades, and TB40 lithium-ion battery systems.
