Buy it if
You will fly with two pilots, your trips are mostly one to four passengers under about 1,100 nm, and you value short-runway access and range per dollar over cabin size.

Sits between the Citation II (550) ($895k) and the Citation Ultra (560) ($2.19M).
Fuel is the biggest line at 300 hours a year; pilots is the biggest fixed cost.
Assumptions
~300 hr/yr, two professional pilots, United States, price basis 09/27/2026: total $956k-$1322k/yr. Fuel None gph @ $7.52/gal. Split fields are midpoints of researched ranges; full ranges and sources in.
Why 65 on purchase value & resale: Below 70: capability per dollar is good, but liquidity and economic-obsolescence exposure are worse than typical for the cohort.

What to know before you buy
Engines & programs
2 x Pratt & Whitney Canada JT15D-4B turbofans, 2,500 lbf takeoff / 2,375 lbf max continuous each (stock).
JT15D-4B: 3,500 hr overhaul interval with mid-life hot section (~1,750-1,800 hr). Extension routes exist (on-condition up to ~5,200 hr with approved monitoring per BJT; TBO Extension claims up to +2,300 hr; SkyWay FLEX ~$23,220 in fees, HSI extra).
Known issues
Two pilots required for all flying; the FAA is rescinding CE-500 single-pilot exemptions, S550 included, effective Sept 28, 2026.
Little payload with full tanks: ~520-760 lb on S550-0086 and later, ~120-370 lb on earlier serials.
Small, aging fleet (160 built, 94 US-registered) with high-time airframes, an S550-unique TKS system, and no confirmed ESP/JSSI engine coverage.
Corrosion hot spots under the lavatory, at the entry-door threshold and around belly antenna bases (PlanePHD); TKS fluid anti-ice system (panel porosity, pump, fluid) unique to the S550 within the 550 line; fuel boost pump wiring and fire bottle wiring ADs; A/C compressor motor brush fire AD with 500-hr repetitive brush replacement; hail damage history on at least one listed aircraft.
Before you buy
Support & programs
No confirmed airframe program for the legacy S550: Textron ProAdvantage/ProParts eligibility for the S550 not shown; JSSI Tip-to-Tail eligibility not confirmed.
Phase-type program: Phases 1-4 each 300 hr/24 mo; Phase 5 1,200 hr/36 mo (major, historically $75k-$200k in 2011 dollars for the Citation II family); calendar items (fire bottles, O2, ELT, halon hydro, transponder/pitot-static); structural/crack inspections from 5,000-10,000 hr, relevant because current listings show 7,955-13,811 hr airframes.
The full review
Our take
More fuel and range than a Citation II: 863 US gal usable and roughly 1,340-1,430 nm with four passengers.
Short-runway Citation performance: 3,350 ft balanced field at 13,200 lb (B/CA 1984) and a direct climb to FL410 at max weight.
Low entry price: priced stock-engine asks of $760K-$1.595M, median $949K (Sept 27, 2026), with Garmin, RVSM and ADS-B retrofit paths approved for the S550.
“The Citation S/II is what Cessna built in 1984 when it wanted more out of the Citation II without changing the cabin.”
The Citation S/II is what Cessna built in 1984 when it wanted more out of the Citation II without changing the cabin. It kept the II's fuselage and CE-500 type rating but added a supercritical wing with swept root cuffs, gap seals and cleaner fairings, JT15D-4B engines, TKS fluid ice protection in place of rubber boots, and 863 US gallons of usable fuel, 121 more than the II according to the type certificate data sheet. Only 160 were built from 1984 to 1988. The S/II cost about $3.3 million new in 1986 against $2.6 million for a straight II, and Cessna put the II back into production. The Citation V then stretched the S/II.
Pilot's take
The catch for anyone coming from single-pilot Citations is crew. The S/II was always a two-pilot airplane with an exemption layered on top, and the FAA is withdrawing that exemption. If you're paying two pilots anyway, the range and short-field numbers are strong for the money. If you wanted to fly it yourself, look at a Part 23 single-pilot jet instead.
Who this is for · A small operator or owner with a professional crew (or an owner-pilot paired with a qualified second pilot) flying roughly 150-350 hours a year on regional trips who wants Citation runway performance and more range than a Citation II for under $1 million.
