The Cessna Citation CJ4 Gen2 is the largest and most capable of Cessna's single-pilot CJ line — a natural step up for owners moving from a King Air or TBM who want more speed and range without a two-crew requirement.
Key takeaways
- Largest of the CJ series, single-pilot certified.
- ~2,165 nm range on Williams FJ44-4A engines.
- Gen2 (early 2020s) added an updated cabin and avionics.
About the Citation CJ4 Gen2
The CJ4 Gen2 pairs Williams FJ44-4A engines with a stand-up cabin and a range of roughly 2,165 nautical miles, giving it genuine coast-to-coast capability with a fuel stop and easy regional reach nonstop. It's the fastest and longest-legged of the straight-wing CJ family.
The Gen2 update brought a refreshed interior, wireless cabin technology, and avionics enhancements over the original CJ4. Owner-operators value the single-pilot certification and the vast Citation service network — one of the deepest in business aviation.
It slots neatly between the smaller CJ3+ and the midsize Citations, making it a common first jet for turboprop owners who want jet speed but not the complexity or cost of a crewed midsize airplane.
Ownership Considerations
- Fuel: the FJ44-4A engines burn roughly 150–190 gallons of Jet-A per hour depending on phase.
- Engine program: Williams TAP/program enrollment supports value and eases financing.
- Single-pilot with mentoring: expect a mentor pilot for a first-time jet owner's initial hours.
- Maintenance: extensive Citation/Textron service network.
- Insurance: light-jet premiums, tied to your jet time and training.
What to Check When Buying a Citation CJ4 Gen2
On a CJ4, confirm Williams engine-program enrollment and status, check the Gen2 cabin/avionics configuration, review scheduled-inspection status and any damage/corrosion history, and confirm a clean title. Use a Citation-authorized facility for the pre-buy and settle your type rating and insurance early.
Financing a Citation CJ4 Gen2
The CJ4 Gen2 finances as a light jet on your balance sheet (typically 15–20% down, often 10–15 years with a balloon). Williams engine-program coverage and a clean title are central, and the deep Citation market supports loan-to-value. Expect a type rating and, as a first-time jet owner, a mentor pilot.
