N420KM

This airframe, registered as N420KM, is a 2004-built Cessna 750 Citation X with manufacturer serial number 7500234. Owned by 420 AVIATION LLC, a corporation based in Seattle, WA, US, the airframe appears in US civil registration and is operated in the executive transport category. The airframe’s listed market value is $5,000,000, reflecting its age, configuration and engine type. Notable registry data for this airframe centers on its corporate ownership and continued operation as a fixed-wing multi-engine executive jet.

The aircraft is typically furnished in an executive layout accommodating 8–12 executive seats in a forward galley and enclosed aft lavatory arrangement consistent with the Citation X example operator interior. It is equipped with Honeywell Primus-class avionics (Primus 2000/Primus-series typical for Citation X), supporting high-speed, long-range business missions up to 3,390 nm and cruise at approximately 460 kts. Based on its US registration and corporate ownership, routine operations are consistent with corporate transport and charter-type missions, with maintenance and crewing practices aligned to support high-altitude, transcontinental flights to the aircraft’s 51,000 ft ceiling. The configuration emphasizes executive comfort and mission flexibility rather than high-density seating.

This specific airframe belongs to the Cessna (Textron Aviation) Citation X family and reflects the type’s emphasis on high-speed, long-range executive transport within the fixed-wing multi-engine category. Performance figures such as a 460-kt cruise and 3,390-nm range position the aircraft for demanding corporate point-to-point missions where speed and altitude capability are prioritized. For buyers and operators, considerations include ongoing maintenance of Rolls-Royce AE 3007C1 engines and avionics lifecycle (Primus-series), with resale and operational economics influenced by age (2004 build) and the prevailing market value of $5,000,000 for this serial.
