The Cessna CitationJet/CJ series (Model 525) are American turbofan-powered light corporate jets built by the Cessna Aircraft Company in Wichita, Kansas. The Citation brand of business jets encompasses seven distinct "families" of aircraft. The Model 525 CitationJet was the basis for one of these families, which encompasses the CJ, CJ1, CJ1+, CJ2, CJ2+, CJ3, and CJ4 models.
The original Model 525 CitationJet was developed as a replacement for the Citation and Citation I, being launched in 1989. Basically an all new aircraft, the CitationJet used a modified version of the Citation's forward fuselage, but with a new supercritical laminar flow wing, and a new T-tail configured tailplane. It is powered by two Williams FJ44 turbofans, and features EFIS avionics and single pilot certification. The CitationJet's fuselage is 11 inches (27 cm) shorter than the Citation I's, but has a lowered center aisle for increased cabin height. The CitationJet's first flight was on April 29, 1991, with its first delivery on March 30, 1993.
The Cessna Citation CJ4 (Model 525C) is part of the Citation business jet family. It is a stretch extension of the CJ3, adding an additional two feet to the CJ3 cabin. The CJ4 also introduces a different wing design than the earlier models. It borrows the moderately swept wing from the Citation Sovereign. The CJ4 was introduced in 2006. The first CJ4 business jet lifted off from McConnell AFB at Wichita, KS on Monday, May 5, 2008, with the first deliveries starting up in 2010.
