Hawker Beechcraft King Air C90A Specs and Description

Background/History

The Beechcraft 65-90 accomplished its first flight in January 1964. Based on the piston-engined Model 65 Queen Air, the -90 featured a pair of the new Pratt & Whitney Canada PT6A turboprop powerplants in place of the earlier Model 65’s Lycoming piston engines. A subsequent pressurized model was developed and designated the King Air 90. Many variants followed including the A90 and B90 powered by the PT6A-20 engine. The C90 series began in 1971 and incorporated the -20 engine, but in 1976 production switched to the 550shp PT6A-21 and continued with this engine variant through the follow-on C90-1 in 1982. The C90-1 was able to utilize higher ITT limits on the -21 engine due to a strengthened empennage, which resulted in higher cruise airspeeds and improve performance. It also incorporated improved cabin pressurization and a beefed-up airstair door. Before production ceased on the C90 in 1982, 507 aircraft were delivered.
