Blackhawk Modifications has announced that its subsidiary, Vector-Hawk Aerospace, will be offering the company’s Blackhawk XP67A Engine+ Upgrade STC kit for the Beechcraft King Air 350ER. The kit is aimed at special mission applications and was recently approved by the FAA for aircraft at up to 17,500 pounds maximum allowable takeoff weight. Blackhawk is offering the 350ER XP37A upgrade in partnership with Sierra Nevada Corporation.
The upgrade includes two new Pratt & Whitney PT6A-67A engines, new five-bladed composite propeller assemblies and spinners from MT and a True Blue Power lithium-ion battery. According to Blackhawk, the XP67A Engine+ Upgrade provides a 25-30 percent increase in power. “The new Pratt & Whitney PT6A-67A upgrade gives the aircraft an amazing increase in performance, especially for aircraft operated in special missions roles at 17,500 pounds gross weight,” said Blackhawk Modifications CEO Jim Allmon.
Installations will be done primarily at Sierra Nevada Corporation-authorized installation facilities, although the company says field installations are also available. The kit comes with training, support and a five-year/2,500-hour enhanced new-engine warranty.
