Blackhawk Earns STC for King Air 300 Engine Upgrade

The package includes replacement of the PT6A-60A engines with new, higher-rated PT6A-67As, and swapping the four-blade Hartzell props for five blades.

The most visible improvement in Blackhawk Aerospace's newly-certified XP67A upgrade for the King Air 300 is the replacement of the four-bladed Hartzell propellers with five-bladed versions. Under the cowlings, the company swapped out the stock PT6A-60A engines with new uprated PT6A-67A engines, resulting in what it describes as "the best performing King Air on the planet." The package lists at $1,787,000, but early birds can shave $100,000 of the cost by ordering before Sept. 31.
