The Model 525 CitationJet (CJ) is Cessna's entry into the light jet bizjet market and belongs to the Citation family brand that encompasses a plethora of solutions to suit the buyer. Developed from the earlier Citation II mark, the new design flew for the first time on April 29th, 1991 and entered production that same year. Over 2,000 of the type have been built to date, claiming for itself customers from all over the world. The CitationJet was itself evolved to become the Model 526 CitationJet, a twin-jet primary trainer geared towards the military market - just two were built however.
The CitationJet uses a proven monoplane arrangement. The mainplanes are set low at the sides of the tubular fuselage. The flight deck is positioned aft of a long, slender nosecone and the tail unit comprises a T-style plane arrangement which seats the horizontal planes at the extreme top of the sole vertical place. The engines were purposely positioned as far aft in the design as possible to mitigate, and mush as possible, noise bleeding into the passenger section. A conventional, retractable and wheeled undercarriage is used for ground-running. Beyond the twin pilot sitting (side-by-side), the aircraft can ferry up to six passengers in comfort.
The CitationJet followed the outgoing Citation I mark which was retired from the Cessna offerings after some 700 were delivered and the new design was formally announced in October of 1989. After its first-flight in 1991, federal certification followed in October of 1992 and the first round of deliveries to awaiting customers was had in March of 1993. In testing, the platform proved itself a worthy successor to the original form - being faster under less power while still retaining its economical approach.
The initial Model 525 forms were powered by the Williams FJ44-1A non-afterburning turbofan engine and these were followed by the CJ1 mark with Rockwell Collins Pro Line 21 series avionics as well as an increase to MTOW. The CJ+, achieving certification in 2005, was next and these switched to the Williams FJ44-1AP turbofan engine (with the General Electric - Honda HF120 being made optional later for retrofit) and added Full Authority Digital Engine Control (FADEC) engine control. The M2 of 2011 included a reworked cabin, uprated FJ44-1AP-21 turbofan engines, and Garmin G3000 avionics.
Model 525A covered the CJ2 of 2000 with its Williams FJ44-2C engines and five-foot lengthening, the CJ2+ of 2006 with modernized avionics and FJ44-3A-24 engines with improved performance, and the short-lived CJ2+ Alpine Edition upgrade option of 2014 with Garmin G3000 avionics and reworked cabin.
The Model 525B encompassed just the CJ3 and CJ3+. The CJ3 of 2002 was the CJ2 with added length and Rockwell Collins avionics while the CJ3+ of 2014 was its upgrade with Garmin G3000 suite.
The Model 525C of 2006 covers the CJ4 with new wings, FJ44-4A turbofan engines, and improved performance. Its upgrade (CJ4 Gen2) was announced in February 2020.
The CitationJet has been formally succeeded in the Cessna product line by the newly-announced "Citation M2 Gen2". Cabin improvements are at the center of the product overhaul with deliveries set to begin in early 2022.
October 2021 - Cessna has announced the Citation M2 Gen2 as a formal upgrade to the Citation M2 light jet line.
