Description
There is simply no other single-pilot certified light jet that can compete for speed,
range, eight passenger capacity and payload capability for anywhere near the price of
this superb Citation S/(Super)II. The runway, high-hot take-off, and climb
performance are extraordinary. Great Engine Times Remaining! Low Total Time!
Fresh Phase I-V Inspections just done 6/2025 at a cost of over $240,000. Excellent
Maintenance and Ownership History! Freon Air, Garmin Upgrades, Thrust Reversers!
The S/II ("Super II," or S550) is the souped-up version of the basic Citation II CE-550.
There were 159 of the S-II’s built from 1984 to 1989. They had the more powerful JT-15D-4D engines which had the same take off thrust but produced more thrust at cruise altitude.
This more powerful engine combined with increased wingspan and the same computer-aided design/manufactured supercritical airfoil design that was then used on all subsequent
Citation V CE-560’s, when coupled with aileron and flap gap seals, along with recontoured
fuselage and nacelle fairings, kicked cruise speeds up by 18-20 knots over the older Citation
II CE-550’s to 403 KTAS, while a larger (862-gallon) fuel capacity permitted 300 nm more
range than the CE-550 for range as great as 1,978 nm. These represent tremendous
improvements in performance, given that the S/II's engines and thus block fuel flows, were
virtually the same as those of the basic Citation II.
S/IIs are distinguished by their swept wing-root cuffs and their use of the TKS "weeping
wing" ice protection system for wing and horizontal stabilizer leading edges. Before the
S/II, all Citations used pneumatic boots for deicing outboard portions of the wing and
electrically heated anti-ice elements on the inboard sections.
The U.S. Navy liked the S/II so much that it bought 15 of them for use in training radar
intercept officers. To obtain more speed, the Navy ordered its S/IIs with wingspans 5 feet 8
inches shorter than standard models. In Navy jargon, an S/II was called a T-47A.
And NetJets launched their now famous fractional jet ownership program with the S-II
which formed the backbone of their start-up operation, and they owned 45 of this model
and they knew a thing or two about bang-for-the-buck performance.
New, S/IIs sold for between $3.5 million to $3.75 million. Today, there are 135 of these still
flying and as of 4/2025 there are 8 for sale ranging in price from $650,000 up to $1,795,000
depending on engine times and inspection status.
