N423SG

This entry covers airframe N423SG, a 2000-built Hawker 800XP with manufacturer's serial number 258472 registered in the US. The airframe is recorded as a standard-certificate Hawker Beechcraft production example equipped originally with Honeywell turbofan powerplants; detailed public ownership timeline, operator/home base, and notable registry actions are not published. Condition and valuation highlights are not published for this specific tail, though the airframe reflects typical configuration and equipment levels for late-production Hawker 800XP jets of its vintage.

The cabin of N423SG is fitted in a typical eight‑passenger executive layout featuring club seating and a belted divan, an enclosed lavatory and a small galley appropriate for short- to mid-range corporate missions. Avionics fit for this airframe is consistent with Honeywell SPZ/Primus family installations, recognizing that retrofit variations occur and final fitment may differ from original installation records. Typical operations for an 800XP like N423SG would include transcontinental and point-to-point executive transport within its 2,432 nm range and cruise profiles near 430 knots, with operational ceilings up to 41,000 ft used for favorable winds and traffic avoidance. Maintenance considerations follow Hawker Beechcraft recommended programs for the 800XP series, with particular attention to older airframe corrosion inspections, engine hot-section and accessory life limits on the Honeywell TFE731-5BR units, and avionics retrofit compatibility.

The Hawker 800XP family occupies the midsize business jet niche, offering balanced speed, cabin comfort for up to eight passengers, and transcontinental capability in the used market. Competing models in mission and age class include mid-size jets from Bombardier and Gulfstream families, with buyer and charter demand driven by platform age, maintenance history, and avionics modernization like Honeywell SPZ/Primus upgrades. Resale and maintenance considerations for a 2000 Hawker 800XP such as N423SG center on engine shop visit status, landed weight and corrosion history, and the extent of avionics retrofits, all factors that materially influence marketability and operating cost.
