Developed into Cessna 526 CitationJet

The Cessna CitationJet/M2/CJ series (Model 525) are light business jets part of the Cessna Citation family, built by the Cessna Aircraft Company in Wichita, Kansas. Its variants are marketed under the CJ, CJ1, CJ1+, M2, CJ2, CJ2+, CJ3, CJ3+, CJ4 and CJ4+ names.

Design[edit]

The CitationJet is a low-wing cantilever monoplane with retractable trailing-link 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. 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 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.

Model 525[edit]

CitationJet
Model 525 serial numbers 0001 to 0359, powered by Williams FJ-44-1A turbofans, are marketed as the CitationJet. Being launched in 1989, it was developed as a replacement for the Cessna Citation I.[4] The CitationJet's first flight was on April 29, 1991, with its first delivery on March 30, 1993.[5]
CitationJet CJ1
Model 525 serial numbers 0360 to 0599 are marketed as the CitationJet CJ1 and are powered by the same Williams FJ-44-1A. It was improved with a more-modern EFIS avionics suite and a moderate increase in maximum takeoff weight.
CitationJet CJ1+
Model 525 serial number 0600 and higher are marketed as CitationJet CJ1+ and are powered by Williams FJ-44-1AP turbofans. With the same airframe, it has an updated avionics package and FADEC engine control.
Citation M2
Model 525 marketed as Cessna Citation M2 are powered by improved FJ44-1AP-21 turbofans offering 10 to 15% more cruise thrust and up to 5% more hot-and-high thrust, and are equipped with modern Garmin G3000 avionics replacing Rockwell Collins Pro Line 21.[6] Launched in September 2011, it is based on the then out-of-production CJ1 variant and features a new cabin layout and a more efficient FJ44 version.[7] The initial M2 prototype first flew on 9 March 2012. It was not a conforming airframe but was testing the Garmin G3000 avionics and Williams FJ44-1AP-21 turbofans. One another aircraft was expected to join the certification program in May 2012 to be used for aerodynamics testing.[8]

The GE Honda HF120 engine is offered as a retrofit to the CJ/CJ1/CJ1+.[9]

Model 525A[edit]

CitationJet CJ2
Model 525A serial numbers 0001 to 0299, marketed as the CitationJet CJ2 is a 5-foot stretch of the CJ1 (Model 525) powered by Williams FJ44-2C turbofans and first delivered in 2000.
CitationJet CJ2+
Model 525A serial numbers 0300 and higher, marketed as the CitationJet CJ2+ and first delivered in April 2006, offer increased performance with updated avionics and Williams FJ44-3A-24 turbofans with FADEC control. In 2014, Cessna started offering an upgrade package for the CJ2+ called Alpine Edition. It incorporates Garmin G3000 avionics and new cabin stylings similar to those introduced by Cessna to the CJ1+ when it became the M2.[10] The CJ2 went out of production due to low demand in January 2016.[11]

Model 525B[edit]

CJ3 side view, seven windows
CitationJet CJ3
Model 525B are marketed as the CitationJet CJ3 are a further stretch of the CJ2 powered by Williams FJ-44-3A turbofans. Unveiled at the September 2002 National Business Aviation Association convention, it first flew on April 17, 2003, was FAA certified in October 2004 and deliveries began in December of that year. The cockpit with Rockwell Collins avionics is designed for single-pilot operation but can accommodate two crew members. Its customizable cabin typically has six club seats in a center-style configuration with an accessible in flight baggage compartment and external baggage access.

Its wing design comes from the moderately swept wing of the Citation Sovereign.[14] Powered by Williams FJ44-4A turbofans, it has a maximum range of 2,165 nmi (4,010 km). Its cabin is 21 inches longer than the CJ3 and can seat up to nine persons plus one in the cockpit. It was introduced in 2006, first lifted off on May 5, 2008, from McConnell AFB in Wichita, Kansas and first deliveries starting up in 2010.

In 2011, the Federal Aviation Administration temporarily grounded the CJ4 and issued an airworthiness directive because of fires in the original Lithium-ion battery 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.[15]
