The Citation CJ4, in brief
Launched in 2010, the Model 525C Citation CJ4 is the largest aircraft in the original CitationJet family — a new, larger-diameter fuselage and an all-new wing set it apart from the CJ1/CJ2/CJ3 line rather than simply stretching an existing airframe. Cessna built roughly 500 CJ4s between 2010 and 2020, when the line was upgraded to the CJ4 Gen2 (later followed by the CJ4 Gen3 in 2026). The CJ4 remains the fastest and longest-range member of the CitationJet family and the only one seating up to 10.
Power comes from two Williams FJ44-4A turbofans, each rated at 3,621 lbf thrust — notably more powerful than the FJ44-3A used on the CJ1/CJ2/CJ3 family. The original CJ4 flies behind Collins Aerospace Pro Line 21 avionics, not the Garmin suite used on the smaller CJ1+/CJ2+/CJ3+ and on the later CJ4 Gen2/Gen3.

Where the CJ4 sits in the CitationJet lineage
The CJ4 is the top of the CitationJet family tree by cabin size and range, sitting above the CJ1/CJ1+/M2, the CJ2/CJ2+, and the CJ3/CJ3+/CJ3 Gen3 — all of which share a narrower fuselage and the smaller FJ44-3A engine. Cessna upgraded the CJ4 twice after the original: the CJ4 Gen2 arrived in 2021 with cabin and technology updates, and the CJ4 Gen3 followed in 2026 with Garmin G3000 PRIME avionics, Emergency Autoland, and factory winglets. The original 2010-2020 CJ4 is the entry point into this family on the used market today.
What financing an original Citation CJ4 looks like
Pre-owned original CJ4s (2010-2020 production) trade broadly from about $5.3M for early 2010-2014 airframes up to roughly $7M-$7.5M for late-production 2019-2020 examples, with avionics options, total time, and engine-program enrollment driving where a given aircraft falls in that range. FLYING Finance structures terms to 20 years with 15%-20% down typical, and can factor an active Williams TAP Blue or similar engine-maintenance program into the underwriting.

Frequently asked questions
How much does a Cessna Citation CJ4 cost?
Pre-owned original CJ4s (built 2010-2020) trade from about $5.3M for early examples to roughly $7M-$7.5M for late-production 2019-2020 aircraft, depending on total time, avionics, and engine-program status.
What’s the difference between the CJ4 and the CJ4 Gen2?
The original CJ4 (2010-2020) uses Collins Aerospace Pro Line 21 avionics. The CJ4 Gen2, introduced in 2021, switched to Garmin G3000 avionics and added cabin technology updates, on the same basic airframe and FJ44-4A engines.

Cessna built approximately 500 original CJ4s between 2010 and 2020, before the line transitioned to the CJ4 Gen2.
