Blackhawk's new PT6A-28 engine upgrade brings new life to the Cheyenne I

Blackhawk Modifications announced FAA approval of another impressive XP engine upgrade option for Cheyenne I operators at NBAA. The new Supplemental Type Certificate (STC) allows for installation of the Pratt & Whitney PT6A-28 engines on the Cheyenne I series in place of the stock PT6A-11. The -28 engines, capable of 620 shp, are flat rated to 500 shp which will allow full power settings to be carried to a much higher altitude. The new performance improvements include greater climb rates, lower time, distance and fuel to climb and faster cruise speeds. A Cheyenne I with this new Blackhawk engine upgrade will achieve the same performance levels as the Cheyenne II series frequenting 250 KTAS, a 25 knot improvement.

Jim Allmon, president and CEO of Blackhawk, is pleased to offer this new economical based engine upgrade to the Cheyenne series. "The Pratt & Whitney PT6A-28 engine is an optimal powerplant for the enduring Cheyenne I that should have been installed from its inception," Allmon said. "For not much more than a typical -11 overhaul, an operator can now attain desirable performance levels which will rejuvenate value and demand. It's a good time to own the celebrated Cheyenne I."

The Blackhawk STC is a bolt-on conversion that utilizes Pratt & Whitney Canada's freshly overhauled or time continued PT6A-28 engines or several variant -28 models that have been converted from PT6A-21 or PT6A-11 engines. The existing three-blade propellers can be retained or an improved four-bladed Hartzell or McCauley propeller is an approved option. The XP28 upgrade comes complete with a new Flight Manual Supplement with full performance charts.

The introductory pricing is based on core exchange and is set for the remainder of 2009 at $475,000. The installation can be completed by any of Blackhawk's distributors encompassing a network of over 50 facilities. Delivery positions are now being reserved.
