N55YS

This entry covers the specific Hawker 400XP airframe bearing US registration N55YS, a 2004 production example, serial RK-366, manufactured by RAYTHEON AIRCRAFT COMPANY. The aircraft is owned by the corporate operator SUPERIOR AVIATION INC, based in Orlando, FL, US, and carries a US registration; no other ownership transfers or notable registry actions are listed for this airframe. The listing for RK-366 cites a market valuation of $1,500,000, reflecting its status as an in-service light business jet with typical mission equipment and a serviceable executive configuration.

The aircraft is configured in a typical 7–9 passenger executive layout for the model, described on the RK-366 listing as a 4-place center club plus forward/rear facing seats; belted lavatory. Avionics fit for this airframe is listed as Rockwell Collins Pro Line 4, a suite that supports regional to continental mission profiles and common charter/operator routings. Operating from its Orlando, Florida base under corporate ownership, the jet’s performance—combined cruise speed and NBAA IFR ceiling—suits short transcontinental hops, intrastate shuttle work, and business group transport. Maintenance considerations follow the Hawker 400XP lineage, with aftermarket support and component overhauls aligned to the airframe’s JT15D-5R engines and Pro Line 4 avionics installation.

The Hawker 400XP (Beechjet 400A) occupies the light business jet niche, offering relatively high cruise speed and altitude capability for its class. Competitors include other light-cabin jets of similar range and seating capacity; market demand typically comes from corporate flight departments, fractional operators, and charter providers seeking economical transregional capability. Resale and maintenance factors for this RK-366 example center on engine-time, avionics enhancements such as the Pro Line 4 fit, and the aircraft’s overall 2004-vintage market valuation.
