McGregor, Texas-based turboprop upgrader Blackhawk Modifications
Inc. has received final FAA approval for the installation of 750
shp Pratt &Whitney Canada PT6A-135A engines on the Beech King
Air C90A/B and E90. With this approval, Blackhawk's STC now covers
all 90-series King Airs, as well as the Cessna Conquest I. Installation
of the 135A engines can increase a King Air's cruising speed
by as much as 50 kt, depending on model, and greatly improves rate
of climb and single-engine performance, and hot-and-high capability.
Blackhawk has already modified 18 Conquest Is, two King Air C90s
and two C90As, and has a Conquest, C90A and C90B in the works. Blackhawk
is at Booth 5287 here at NBAA.
