Developed into Cessna 526 CitationJet

The Cessna CitationJet/M2/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+, M2, CJ2, CJ2+, CJ3, CJ3+, CJ4 and CJ4+ models.


The original Model 525 CitationJet was developed as a replacement for the Citation and Citation I, being launched in 1989.[4] 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.[5]

The Cessna Citation CJ1 (also Model 525) was developed as an improved version of the original CitationJet.[6] The CJ1 improved on the CitationJet by adding a more-modern EFIS avionics suite and a moderate increase in maximum takeoff weight. The CJ1 has been replaced by the CJ1+, which shares the same airframe but has an additional updated avionics package, and FADEC to allow the engines to be controlled by computer rather than mechanical controls. The GE Honda HF120 engine is offered as a retrofit to the CJ1.[7]

Cessna Citation M2 at Key West, Florida

The Cessna Citation M2 was launched in September 2011 as a new light business jet, it is based on the then out-of-production CJ1 variant and features a new cabin layout and a more efficient version of the Williams FJ44 engine.[8] It first flew on 9 March 2012.[9]

The initial M2 prototype, which first flew on 9 March, is not considered a conforming airframe; it aircraft will serve as a conforming platform for testing of the Garmin G3000 avionics and Williams FJ44-1AP-21 turbofan engines, which will be its primary role in the certification program. The certification program will involve only one other aircraft, which is expected to join the program in May. The second aircraft (which will be considered completely conforming to the certificated design) will be used for aerodynamics testing.[10]

An M2 may cost around US$2-3 per nautical mile to operate, whereas the G650 and similar may cost $5-6[2]

The Cessna Citation CJ2 (Model 525A) is a 5-foot stretch extension of the Cessna Citation CJ1 (Model 525) first delivered in the year 2000. The 525A comes in two forms, the original CJ2 and the newer CJ2+, which has updated avionics, increased performance, and FADEC controls. The CJ2+ was first delivered in April 2006 and was out of production due to low demand in January 2016.[11]

The Cessna Citation CJ3 (Model 525B) is part of the Citation business jet family. It is a stretch extension of the CJ2, which, in turn, was a stretch of the CJ1. The aircraft was unveiled in September 2002 at the National Business Aviation Association (NBAA) convention. It took its first and second flight on the same day on April 17, 2003. It was FAA certified in October 2004 and delivery of the CJ3 began in December of that year.

The CJ3's cabin comes standard with six club seats in a center-style configuration, although it is customizable to the owner's specifications. The cockpit was originally designed for a single-pilot operation, but it can accommodate up to two crew members. Its flight deck is composed of a Rockwell Collins state-of-the-art avionics system. It has external baggage access for added convenience. There is also a cabin baggage compartment that is accessible in flight. It also features a trailing-link tricycle landing gear.

A CJ4. The 525C CJ4 has the longest fuselage of the CitationJet range

The Cessna Citation CJ4 (Model 525C) is part of the Citation business jet family. It is a stretch extension of the CJ3, adding another 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, Kansas, on Monday, May 5, 2008, with the first deliveries starting up in 2010.[12]

In 2011, the Federal Aviation Administration temporarily grounded the CJ4 and issued an airworthiness directive because of battery fires in the Lithium-Ion original equipment:

We are adopting a new airworthiness directive (AD) for certain Cessna Aircraft Company (Cessna) Model 525C airplanes. This emergency AD was sent previously to all known U.S. owners and operators of these airplanes. This AD requires replacing certain lithium-ion batteries installed as the main aircraft battery with either a Ni-Cad or a lead acid battery. This AD was prompted by a report of a battery fire that resulted after an energized ground power unit was connected to one of the affected airplanes equipped with a lithium-ion battery as the main aircraft battery. We are issuing this AD to correct the unsafe condition on these products.[13]


The CitationJet is a low-wing cantilever monoplane with retractable tricycle landing gear, a pressurized cabin, a T-tail, and is powered by two Williams FJ44 turbofan engines that are pylon mounted on the rear fuselage.
