CESSNA CITATION CJ1 / CJ1+
The CJ1 was designed for people who actually use their aircraft
The story of the CJ1 starts with the CitationJet Model 525.
The prototype first flew in 1991. FAA certification followed in 1992, and the first customer aircraft was delivered in 1993.
The CJ1 came later, in 2000.
Cessna took the basic 525 concept and developed it into an aircraft that could work very well for a small business, an owner-pilot or a private operator who needed a jet for regular travel.
That idea still holds up.
You can leave your office, get to the airport, fly above the weather and arrive much closer to the place where you actually need to be.
No airline timetable.
No connection.
No spending half a day getting somewhere that takes a couple of hours in a business jet.
That is the value of the CJ1.
Specifications That Created a Category
• Range: 2,408 km (1,300 nm) - practical for regional operations;
• Speed: 720 km/h (389 knots) - efficient, not fast;
• Capacity: 5 - 7 passengers in the compact cabin;
• Engines: Williams FJ44-1AP (1,900 lbf) - efficient, simple, reliable;
• Operating cost: ~$1,000/hour - half of competitors.

The CJ1+ arrived in 2005 with Williams FJ44-1AP engines, FADEC and updated avionics.
Three CJ1 facts worth knowing
  • The first one is a little surprising.
The aircraft people now call the CJ1 comes from the Model 525 CitationJet that first flew in 1991. The first customer delivery was in 1993.
  • The second matters when comparing aircraft.
The CJ1 was certified in 2000. The CJ1+ followed in 2005 with FADEC-equipped FJ44-1AP engines and updated avionics.
  • The third is relevant to today's buyer.
The CJ1 has not simply been left behind as an old aircraft. Textron Aviation announced an OEM-supported Garmin avionics upgrade for the model in 2025.
So an older airframe does not automatically mean an old cockpit.
Cessna CitationJet CJ1 / CJ1+ competitors
Before buying a CJ1 jet for sale, I would also look at the aircraft competing for the same mission.

Embraer Phenom 100EX / Published range: about 1,178 nm. / Passengers: up to 8, depending on configuration.

Hawker 400XP / Published range: about 1,500 nm. / Passengers: up to 8, depending on configuration.

Learjet 35 / Range: approximately 1,500 nm class. / Passengers: commonly around 6, depending on configuration.

And then there is the Citation CJ2.
If you regularly need more passengers, more cabin or more range, the CJ2 deserves a place in the conversation.
If you do not, why buy the larger aircraft?
That is the question.
The Verdict
The Cessna Citation CJ1 is a small jet with a very clear job.
Carry a small group of people.
Move them quickly.
Operate at altitude.
Get them closer to where they need to be.
And do it without buying a larger aircraft simply because it has more seats.
That is why the CJ1 remains interesting on today's pre-owned market.
The CJ1+ adds meaningful engine and avionics changes, and modern avionics upgrades are available for the CJ1. The 525 family also has a long operating history behind it.
