Cessna Fanjet 500
Cessna CE-500 Citation
Cessna CE-501 Citation I
Announced in 7 October 1968, Cessna's first business jet, the FanJet 500, made its maiden flight on September 15, 1969. Renamed the Model 500 Citation shortly after the first flight, the eight-seat Model 500 has an overall configuration similar to that of earlier Cessna twins except for its powerplant installation. This featured two 990kg Pratt & Whitney Canada JT15D-1 turbofans, mounted in pods on each side of the rear fuselage just aft of the wing trailing edge.
First flown on 15 September 1969, development flying resulted in a number of changes, and it was not until 1972 that initial deliveries were made. The Citation received FAR Part 25 certification in September 1971 and the first Citation business jet was delivered to Levitz Furniture Corp in 1972.
In 1976 deliveries began of an improved Model 501 Citation I with increased wing span and similarly rated but improved JT15D-1A engines. This was followed soon after by the Citation 1/SP version certificated for single-pilot operation. This had JT15D-1A engines, thrust reversers, and a slightly increased wingspan.
When production ceased in June 1985, 691 Citation Is had been delivered.
