Blackhawk Aerospace announced on Wednesday that it has started FAA certification flight testing for its new Pilatus PC-12 XP67P Engine+ Upgrade program. The program replaces the PC-12’s stock Pratt & Whitney Canada PT6A-67B engine with the PT6A-67P model. The -67P offers higher internal turbine temperature (ITT) limitations and produces 142 more thermodynamic horsepower than the -67B, which the company noted will allow an upgraded aircraft to maintain full power to FL250.
