History
The Cessna Citation II (Model 550) series of Citation jets are light corporate jets built by Cessna. Stretched from the Citation I, it was announced in September 1976, first flew on January 31, 1977 was certified in March 1978. The II/SP is a single pilot version, the improved S/II first flew on February 14, 1984 and the Citation Bravo upgraded with new avionics and P&WC PW530A turbofans on April 25, 1995, while the United States used it as the T-47. Production ceased in 2006 after 1184 were delivered.
Design
The Citation II (Model 550) stretches the Citation I fuselage by 3ft 9in, increasing seating capacity to 10 and baggage capacity. Wingspan was increased, its larger fuel capacity and more powerful, 2,500 lbf Pratt & Whitney Canada JT15D4 engines provided higher cruise speeds and longer range.
Development
The stretched Citation was announced in September 1976, it first flew on January 31 1977 and FAA certification was awarded in March 1978, the II/SP is the single pilot version. A total of 688 aircraft were delivered.
The improved Citation S/II (Model S550) was announced in October 1983 and first flew on February 14, 1984, before certification in July. It gained a supercritical airfoil developed for the Citation III and JT15D4B turbofans. It replaced the II from 1984, but the II resumed production from late 1985, and both were built until the Bravo introduction. Deliveries of the S/II amount to 160.
The improved 2,500 lbf JT15D-4B has higher temperatures components, allowing more thrust at higher altitudes. It could seat 11 people and fuel capacity was increased to 5820 lbs. TKS fluid de-icing was used on airfoils leading edges in addition to bleed air for the engines.
Variants
Citation II
Model 550 is a larger stretched development of the Model 500 first produced in 1978. Initially replaced by the S/II in production, but was brought back and produced side-by-side with the S/II until the Bravo was introduced.
T-47A
Model 552 is the military designation of the Citation II. The United States Navy purchased 15 T-47A aircraft as radar system trainers.
Citation II/SP
Model 551 is certified for single-pilot operations.
Citation S/II
Model S550 incorporated a number of improvements, especially an improved wing. Replaced the II in production.[2][10]
Citation Bravo
Model 550 is an updated II and S/II with new PW530A engines, landing gear and Primus 1000 avionics.[11][12] The last Citation Bravo rolled off the production line in late 2006, ending a nearly 10-year production run of 337 aircraft.
