N840JH

This entry covers airframe N840JH, a factory-built Cessna S550 Citation S/II delivered in 1987 with serial number S550-0144. The aircraft is registered in the United States and is owned by N501BZ LLC, a Boca Raton, Florida–based corporation; the owner's corporate registration and location are notable elements of the airframe’s registry record. Operator and home base activities are centered in Boca Raton, FL, and registry remarks include listing references to a Bravo upgrade in cabin configuration. Public listings for this specific airframe highlight service history and condition notes consistent with a maintained executive Citation S/II of this vintage.

The cabin on N840JH is configured in a six–to–eight place executive club layout, with listings noting the Bravo upgrade as an interior variant; this supports typical light corporate transport and owner-flown business missions. Avionics fit includes a Universal 890R EFIS, dual Universal UNS-1LW FMS units, Sperry SPZ autopilot, a Collins communication and navigation suite, Collins TDR-94D Mode S transponder, Collins weather radar and TCAS, enabling IFR cross-country and airways operations to the airframe’s published range and ceiling. Typical mission profiles for this specific aircraft would include transcontinental U.S. hops and regional international legs within the ~2,000 nm radius while operating from Boca Raton as an owner-corporation base. Maintenance considerations for this airframe reflect the Williams FJ44 powerplant and the avionics suite modernization relative to original 1987 systems, as implied by the EFIS and dual FMS installations.

The Cessna S550 Citation S/II represented a light-class, twin-engine business jet niche focused on short- to mid-range corporate travel, with performance such as 403 kts cruise and a 43,000 ft ceiling appealing to owner-operators and charter fleets. Competing models in this segment historically included similar light jets offering low single-pilot operating costs and executive cabins; demand centers on buyers seeking efficient point‑to‑point regional capability. For resale and maintenance of this specific airframe, factors include the Williams FJ44 engine commonality, updated avionics package, and documented cabin upgrade, all of which affect serviceability and market appeal for prospective corporate or charter operators.
