About the King Air® F90
The evolution that led to the King Air® F90 began with the Model C90 which was introduced in 1971. The C90 featured an increased wingspan over the B90 by 4 ft 11 in to 50 ft 3 in. Maximum Take-off weight was increased to 350 lb to 9,650 lb and upgraded with PT6A-20A engines. During this time the Model E90 was also introduced, broadly similar outside having PT6A-28 engines. Further refinements of the series would produce the Model F90 and follow-on Model F90-1.
The F-models took the Model 200 King Air® T-tail and combined it with the fuselage and wings of the E90. The engine used was the PT6A-135 of 750 shp (560 kW) driving four-bladed propellers. On January 16th, 1978, The F90 prototype flew for the first time. 203 production versions would follow between 1979 and 1983, with the F90-1 superseding the F90 that year.
The F90-1 was built with redesigned engine cowlings, upgraded PT6A-135A engines, hydraulic landing gear, and triple-fed electrical bus. Only 33 were built by the time production on the model was terminated in 1985.
