Hawker Beechcraft King Air F90-1 Specs and Description

Aircraft Description


In January 1964, the first Beechcraft 65-90 took to the air. Based on the piston-engined Model 65 Queen Air, the -90 featured then-new Pratt & Whitney Canada PT6A turboprop powerplants in place of the earlier 65’s Lycoming 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 powered by the PT6A-21. In April 1972, Beech announced the E90, which was powered by the PT6A-28 flat-rated to 550 shp. This model was followed in 1979 by the King Air F90 which featured the T-tail of the 200-series King Air, and a new wing derived from that of the 100-series, and four-bladed propellers driven by a pair of PT6A-135’s. Production of the King Air F90 ran from 1979 through 1983, when the F90-1 was introduced utilizing PT6A-135A engines. The F90-1 was produced from 1983 to 1985 during which time 33 aircraft were manufactured.


The King Air F90-1 is powered by a pair of Pratt & Whitney Canada PT6A-135A turboprop engines rated at 750shp each, driving four-bladed, full-feathering, reversible, constant speed propellers. Engine inspection interval 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.

Design Features

The King Air F90-1 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 wheeled 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 F90-1 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.
