LAS VEGAS, NV – October 9, 2017 – Through Blackhawk Modifications’ subsidiary government and military sales division, Vector-Hawk Aerospace (VHA), the companies have teamed with Sierra Nevada Corporation (SNC) to offer the Blackhawk XP67A Engine+ Upgrade STC Kit for the King Air 350ER at 16,500 and 17,500 pounds maximum allowable takeoff weight (MTOW).

Specifically developed for military and government operations, the offering will include two factory-new Pratt & Whitney Canada (P&WC) PT6A-67A engines, new MT 5-bladed composite propeller assemblies and spinners, and a True Blue Power lithium-ion battery. Training, support, and a five year/2,500 hour enhanced new-engine warranty are also included.

“Blackhawk is proud to be teamed with a company like SNC on this program,” said Jim Allmon, Blackhawk’s President and CEO. “With Blackhawk’s engineering and branding expertise coupled with SNC’s military and government reach, this program will prove to be highly successful. Our government and military division, Vector-Hawk, was instrumental in the facilitation of the program, and my congrats go to VHA President, Pete Franks, for his efforts to team us with SNC.”

The XP67A will provide a 25-30% increase in power, which translates into improved climb and cruise performance for King Air 350ERs especially on hot days at high altitudes. Although the PT6A-67A will produce a 400 thermodynamic SHP increase over the stock PT6A-60A, the Blackhawk Engine+ Upgrade will actually reduce the overall weight of the aircraft by about 18 pounds.

“Sierra Nevada Corporation is excited to work with Vector-Hawk and Blackhawk, world leaders in aircraft performance improvements, to offer this capability for greatly increased performance in high-density altitude areas of operation,” said Tim Owings, Corporate Vice President of SNC’s Integrated Mission Systems business area. “This will truly be a game changer, offering increased safety, performance, and mission capability.”

Testing is underway at Blackhawk Headquarters in Waco, TX, and is expected to be completed in the first quarter of 2018. Once approved, SNC will have exclusivity to provide the Blackhawk Engine+ Upgrade STC Kit to the Special Missions market for U.S. and most foreign governments/military aircraft weighing 16,500 lbs. and above. SNC will complete the installations at their network of authorized install facilities.
