Blackhawk Aircraft Modifications says it expects to be able to deliver re-engined King Air 350s that will offer significant performance improvements from the factory models by May of 2017. Blackhawk will begin flight testing a 350 with Pratt & Whitney Canada XP67A engines this month. The airplane came with PT6A-60A engines developing 1050 horsepower and the new mills put out 1,200 horses. The switch also requires a beefier prop and it's working with MT Propeller on the conversion. Some aircraft already have MT five-bladed props and they just need new hubs and spinners. Company VP Bob Kromer outlined the program at NBAA press day in Orlando on Monday.
