N121AT

This entry covers airframe N121AT, a production Cessna 750 Citation X built in 1998 with serial number 750-0057. The aircraft is registered in the US and is recorded as owned by JEA MEDIA LUNA SURFACE LP, a partnership based in Bearden, AR, US; this ownership represents the principal known registry action for the airframe. The airframe's configuration and maintenance status have produced an estimated market value of $3,500,000, reflecting its age, equipment baseline and the secondary market for late-1990s ultra-long-range business jets. The operator/home base is tied to the owner's location in Bearden, Arkansas, and there are no other publicly documented registry transitions or notable incidents for this specific tail in the available data.

The cabin for this airframe follows a typical executive layout with double-club seating configurable for 8–12 occupants and the option for a divan; exact disposition varies by interior fit-out for N121AT. Avionics were originally delivered with a Honeywell Primus 2000 suite; operators commonly retrofit later to Primus Elite or equivalent modern avionics during lifecycle upgrades, though retrofit status for this serial is not detailed beyond the original fit. Typical missions for this Citation X include transcontinental and intercontinental executive transport within its 3,070 nm range at high-speed cruise around 525 kts, taking advantage of a 51,000 ft ceiling for efficient, high-altitude cruise. Maintenance considerations for this specific aircraft reflect the Citation X program standards, including required attention to the AE3007C engines and avionics modernization when preparing the airframe for continued commercial or private operation.

The Cessna 750 Citation X occupies a high-speed, long-range niche among late-1990s large-cabin business jets, distinguished by one of the fastest civil-transport cruise capabilities in its era. Competitors historically include other long-range business jets offering similar transcontinental performance, and resale demand typically favors airframes with updated avionics and well-documented maintenance histories. For a 1998 serial like 750-0057, buyers and charter operators will weigh the cost of potential avionics upgrades and remaining engine cycles against the airframe's inherent performance advantages, with those factors heavily influencing maintenance planning and resale valuation.
