 VALUE KA ADDED Blackhawk Receives FAA Approval of New
                Engine Upgrade Program for KA300
Blackhawk Aerospace announced that the Federal Aviation Administration (FAA) has issued a Supplemental Type Certificate (STC) for the XP67A Engine+ Upgrade for both the 14,000 and 12,500 lb. gross weight versions of the King Air 300. This upgrade removes the standard 1050 shaft horsepower (SHP) PT6A­60A engines and Hartzell 4­blade metal propellers and replaces them with factory­new 1200 SHP PT6A­67A engines and Hartzell 5­blade composite propellers.
The company says the advantages of the upgrades are more available power from the PT6A­67A engines and more available thrust from the advanced shape and aerodynamics of the Hartzell 5­blade composite propeller for superior performance, noise abatement and weight reduction. The results from combining these two products delivers the best performing King Air on the planet.
From the first flight test to the receipt of the STC, Blackhawk’s engineering team completed the task in just nine months and flew 80 hours of certification flights. During flight testing, the power pairing delivered
