Blackhawk XP28 Engine Upgrade for the King Air C90The Blackhawk XP28 is a simple, bolt-on upgrade for the King Air C90 that replaces existing PT6A-21 engines with current generation PT6A-28. The existing PT6A-21 engines are overhauled and upgraded to a PT6A-28 through an STC developed by Atlantic Turbines. The engines are then installed on the C90 airframe under Blackhawk’s STC to give your King Air more horsepower at altitude, like the popular E90.
