Cessna Citation I / 500: Complete Specs, Performance, and Buyer's Guide (2026)
The Cessna Citation 500 and its successor variants (Citation I and Citation I/SP) is the founding aircraft of the entire Cessna Citation family, with production running from 1971 to 1985. Powered by twin Pratt & Whitney Canada JT15D-1 (later JT15D-1A) turbofan engines producing 2,200 lbf each, the Citation 500/I delivers up to 1,328 nautical miles of range (Citation I with updated configuration), 348 ktas typical cruise, and a 41,000 ft service ceiling (improved from 35,000 ft on original 500s). A total of 689 Citation 500, Citation I, and Citation I/SP aircraft were built before production ended in 1985. Pre-owned market today: $300,000 to $1.25 million (latter for Sierra Industries Eagle II-converted aircraft).
For owner-operators wanting the lowest-cost entry into certified twin-jet ownership, the Citation 500/I family remains uniquely positioned. The tradeoff is dated 1970s technology and modest performance.

History: The "Slowtation" That Made Cessna
In October 1968, Cessna announced plans to build an eight-place business jet specifically designed for operations from shorter airfields. The strategic positioning was novel: rather than competing with existing jets like the Sabreliner and HS.125, the Citation aimed to compete with light-to-medium twin turboprops.
Development timeline:
- October 1968: FanJet 500 announced
- September 15, 1969: First flight (prototype FanJet 500)
- September 9, 1971: FAA certification as Citation 500
- 1976: Citation I update with extended wing, thrust reversers, higher gross weight, 41,000 ft ceiling
- 1977: Citation I/SP (Model 501) single-pilot variant
- 1985: Production ends after 689 total aircraft
Cessna had spent $35 million (then half the company's worth) developing what initially looked like a slow jet. Industry observers were skeptical. Learjet salesmen mocked the Citation as the "Nearjet" and "Slowtation." But the gamble paid off: by 2018, Cessna had built roughly one-third of all business jets in service worldwide.
Citation 500 vs Citation I vs Citation I/SP
| Variant | Years | Engines | Ceiling | Pressurization | Key Notes |
|---|---|---|---|---|---|
| Citation 500 | 1972-1976 | JT15D-1 (2,200 lbf) | 35,000 ft | 7.6 psi | Original certification |
| Citation I | 1976-1985 | JT15D-1A | 41,000 ft | 8.6 psi | Longer wing, thrust reversers |
| Citation I/SP (501) | 1977-1985 | JT15D-1A | 41,000 ft | 8.6 psi | Single-pilot certified |
The Citation I/SP was a major innovation for the era: a twin-engine jet certified for single-pilot operation, opening jet ownership to a much broader buyer pool.
Cabin Interior
The Citation cabin is small by modern standards but generous for the early 1970s light-jet era:
| Cabin Measurement | Value |
|---|---|
| Cabin Length | 12 ft 8 in |
| Cabin Width | 4.92 ft (59 inches) |
| Cabin Height | 4.33 ft (52 inches) |
Seating Configurations
Original Citations offered 5, 6, or 7 passenger main cabin layouts. The standard Citation 500 typically seated 5 passengers plus 2 pilots, totaling 7 occupants.
Baggage
- Nose baggage: 17 cu ft
- Cabin internal storage: 40 cu ft
- Total: 57 cu ft (less than the current Citation Mustang's 63 cu ft)
Performance
Speed and Range
| Performance Metric | Citation 500 | Citation I |
|---|---|---|
| Max Cruise Speed | 332 ktas | 348 ktas |
| Range (NBAA IFR) | 911 nm | 1,328 nm |
| Service Ceiling | 35,000 ft | 41,000 ft |
| Balanced Field Length | 3,851 ft | 3,500 ft (with mods) |
Climb
The Citation I climbs at 2,719 fpm with both engines at full power.
Engines
Two Pratt & Whitney Canada JT15D turbofans, each producing 2,200 lbf of thrust. The JT15D family was based on Cessna's experience with the T-37 Tweet twinjet trainer.
Engine TBO: 3,500 hours. Overhaul cost approximately $350,000 for a pair (relatively expensive vs hours of life).

| Sierra Eagle II Conversion (any year) | Up to $1,500,000 |
Mission Profile
Best fit profiles:
- Lowest entry into twin-engine jet ownership: $300K-$700K acquisition cost
- Owner-Operators With Sierra Eagle II Upgrade: Performance comparable to modern light jets
- Single-Pilot Operators (I/SP): Cost-effective owner-flown jet
- Operators Willing to Invest in Engine Programs: 3,500-hour TBO requires planning
Less suited if:
- You need long-range missions (970 nm typical with 4 pax in stock Citation I)
- You require modern avionics
- You want low-cost engine TBOs
- You need quiet cabin (original JT15D engines are loud)
- You require fast cruise (stock 348 ktas is the slowest in the Citation family)
Pros and Cons
What the Citation 500/I Does Well
- Lowest-cost entry into twin-jet ownership
- Single-pilot certified (I/SP variant)
- Excellent short-field performance (3,500 ft strip)
- Citation parts and service network supports the type
- Founder of the Citation family with extensive service history
- Sierra Industries conversions deliver near-modern performance
Tradeoffs to Understand
- Slowest cruise in Citation family (348 ktas)
- 970 nm realistic range with 4 passengers (stock)
- 3,500 hour engine TBO with expensive overhauls
- 1970s avionics (extensive retrofit market)
- Cabin smaller than modern VLJs
- Original Citation 500 limited to 35,000 ft ceiling
Frequently Asked Questions
How far can a Citation I fly?
The Citation I has a maximum range of 1,328 nautical miles at altitude with 1,562 lb payload and 45-minute reserves. Realistic range with 4 passengers is approximately 970 nautical miles.
What is the difference between Citation 500 and Citation I?
The Citation I (1976) added a 38-inch wingspan extension, thrust reversers, JT15D-1A engines, higher gross weights, 41,000 ft service ceiling (up from 35,000 ft), and increased cabin pressurization (8.6 psi vs 7.6 psi) over the original Citation 500.
Is the Citation I single-pilot certified?
The standard Citation 500 and Citation I require two pilots. The Citation I/SP (Model 501, 1977+) is the single-pilot certified variant.
What is the Sierra Eagle II conversion?
The Eagle II is a Williams FJ44 engine retrofit by Sierra Industries that delivers 35% more cruise thrust, 40% lower fuel burn, 54 knots faster cruise, and the ability to climb directly to 43,000 ft. Approximately 175 Citation 500/I aircraft have received Sierra conversions.
Why is the Citation I called the "Slowtation"?
Cessna's choice of turbofan engines and straight wings made the Citation cruise significantly slower than other business jets of its era (Learjet and Sabreliner). Industry observers nicknamed it the "Slowtation," though Cessna's actual marketing name references Citation, the champion American Thoroughbred racehorse who won the 1948 Triple Crown.
Can the Citation I be operated on short runways?
Yes. With thrust reversers and the Citation I upgrade, the aircraft can operate from 3,500-ft runways and even unpaved turf strips. The Sierra Eagle II conversion enables 3,000-ft operations.
The Bottom Line
The Cessna Citation 500/I family is the founding aircraft of the world's largest business jet family. At pre-owned pricing of $300,000 to $1.25 million, the Citation 500/I remains uniquely positioned as the lowest-cost entry into twin-engine jet ownership. The tradeoffs are real: dated technology, slow cruise, expensive engine overhauls, and modest range. But for value-focused operators (particularly with Sierra Eagle II conversions), the Citation 500/I remains a viable platform.
