In January 1964, the first Beechcraft 65-90 took to the air. Based on the piston-engined Model 65 Queen Air, the -90 featured the then-new Pratt & Whitney Canada PT6A turboprop powerplants in place of the earlier 65’s Lycoming IGSO-480-A1E6 flat-six piston engines. A pressurized model was developed, and was designated the King Air 90. Many variants followed including the PT6A-20 powered A90 and B90, and the C90 series powered by the PT6A-21. The E90, introduced in 1972, was essentially an upgraded C90 powered by a pair of PT6A-28 turboprop engines. The F90 introduced in 1979 was powered by the PT6A-135 engines which were flat-rated to 750 shp and featured the T-tail of the King Air 200 series. A total of 203 were produce.
The King Air F90 is powered by a pair of Pratt & Whitney PT6A-135 turboprop engines flat-rated to 750shp each, driving a pair of four-blade, full-feathering constant speed propellers. Inspection interval on the engines is 3,600 hours
A typical avionics installation for the King Air F90 includes dual Collins VHF 20A comms, dual VIR 30 navs, DME, ADF, Sperry SPZ 200A flight director/autopilot, dual Collins TDR 90 transponders, and Bendix RDR 1200 color weather radar
The King Air F90 is a pressurized, twin-engine turboprop business aircraft configured as a cantilever low-wing monoplane with a T-tail. It has retractable tricycle landing gear with a single nose wheel and dual wheels on each main landing gear. Entry is provided by a large airstair door located on the port side of the aft fuselage. The aircraft utilizes dual bleed air pressurization and heat. The four-bladed propellers have lower tip speeds, resulting in reduced cabin noise levels.
The King Air F90 can accomodate up to eight passengers, although it is more commonly configured for six passengers, with four seats arranged in a club, one seat across from the door, and a belted lavatory seat. An airstair door is located aft of the wing on the port side of the fuselage and the baggage compartment is in the aft cabin beyond the lavatory. Cabin height is 4.8ft., cabin width is 4.5ft. and cabin length is 12.7ft.
