Blackhawk Aerospace has certified its 30th major powerplant and ancillary product STC. The milestone STC covers Blackhawk’s XP67A Engine+ upgrade for the Beechcraft King Air 300, which is on display at this week’s EAA AirVenture in Oshkosh, Wisconsin. “This STC represents the pinnacle of achievement for Blackhawk, raising the bar of performance and value standards to the highest levels yet,” said Blackhawk president and CEO Jim Allmon.

Blackhawk also recently received EASA and British Civil Aviation Authority certifications for the True Blue Power TB44 lithium-ion battery for the King Air 350 series twin turboprop. “The TB44 is a great example of the cutting-edge technology that Blackhawk supports in addition to our engine performance upgrades,” Allmon added.

According to Blackhawk, its XP67A Engine+ upgrade—which includes five-blade composite propellers—improves the King Air 300’s available horsepower by 25 percent, increasing speed by up to 50 ktas, and reaching FL350 within 19 minutes versus 42 minutes in a “stock” King Air 300.
