N501RX

This entry covers airframe N501RX, a Cessna 501 Citation I/SP built in 1978 with serial 501-0060. The airplane is registered in the US and is owned by BRIXTEL JET LLC, an LLC based in Glendive, MT, US. Recent listings and registry data indicate the airframe is offered with a valuation around $550,000, and documentation highlights an executive interior with convertible seating options. Commercial listings note convertible 5–6 passenger arrangements and a 5‑seat passenger commercial listing variation.

The specific cabin of N501RX is configured in an executive layout with a club/forward arrangement commercially listed as a five‑seat passenger configuration, while sales materials and listings advertise convertible five–six passenger arrangements. The cabin also includes an aft belted potty and a refreshment center as noted in the listing description. Avionics fit on this airframe combines modern Garmin navigation components — dual GNS‑480 WAAS — with Garmin GTX transponders supporting ADS‑B and a Garmin GMX‑200 weather display, supplemented by a Sperry SPZ‑500 autopilot/flight director; Collins DME and radar are listed as options on recent advertisements. Based in Glendive, Montana, the airframe is suitable for regional executive missions and short‑to‑mid‑range charters consistent with its range and seating.

The Cessna 501 Citation I/SP occupies a light twin-jet niche as an early Citation variant, offering transcontinental capability for eight seats at modest acquisition cost compared with newer models. Competitors historically include other light business jets powered by small turbofans, and prospective buyers assess this airframe on avionics upgrades, interior refurbishment, and engine maintenance status. Resale and maintenance considerations center on age (1978 manufacture), the cost of comprehensive inspections and upgrades, and the value proposition reflected in the listed $550,000 asking price.
