Blackhawk Aerospace has received FAA supplemental type certificate (STC) approval for the integration of its XP67A Engine+ upgrade with the Collins Aerospace Pro Line Fusion avionics system. Under the STC, factory Fusion-equipped King Air 350is and 360s are now eligible for Blackhawk Aeropace’s aftermarket XP67A conversion, which increases the power and fuel efficiency of these aircraft.

According to Blackhawk Aerospace, the conversion—which uses Pratt & Whitney Canada PT6A-67A engines—translates to a significant reduction in operational costs and an increase in longevity for King Airs.

“This certification brings significant value to King Air 360 owners and operators, offering a powerful and efficient engine upgrade option,” said Blackhawk Aerospace president Edwin Black. “Integrated with the Pro Line Fusion avionics system, the XP67A Engine+ upgrade enhances the capabilities and market value of these aircraft. This certification effort expands eligibility for more than 300 recently delivered aircraft.”

Compatible with all Pro Line Fusion software phases, the XP67A upgrade is a versatile option for King Air 360 owners. The Phase 3.7 software update as part of the upgrade package brings several benefits, including controller-pilot datalink communications, as well as a Privacy ICAO Address.
