The highly successful Citation Jet was developed as a replacement for the Citation and Citation I. Cessna announced the Citation Jet at the annual NBAA convention in 1989. The Citation Jet is an updated version of the Citation 500. The fuselage is the same but it has a new T-tail and a new supercritical laminar flow wing. All Citation Jets are equipped with two Williams Rolls FJ44 engines with paddle thrust reversers.
The CJ1+ continued the process of improvements to the “CJ” line with further enhancements to the engine with two FJ 44-1AP engines and somewhat higher weights. Also added is an upgraded Collins Pro Line 21, as found in the CJ3. Other improvements include LED lighting in the cabin, redesigned seats, and updated cabin appointments.
The first flight of the CJ1+ took place in October 2004, with certification and deliveries commencing in 2005.
