N399LF

The airframe N399LF is a 2003-built Cessna 750 Citation X (manufacturer: Cessna (Textron Aviation)) bearing serial number 750-0213. It is registered in the United States and recorded in civil registries to UP UP AND AWAY LLC of Broomfield, Colorado, which is the current owner and operator/home base. The airframe presents as a mature, mid-life Citation X example with an indicated market valuation of $5,100,000 consistent with late-model early-2000s airframes in active private or charter roles. Registry entries identify the aircraft as a fixed-wing multi-engine transport operated commercially/private by the listed LLC.

The cabin of N399LF is fitted in a standard executive Citation X arrangement accommodating an executive 9–12 passenger layout with a forward galley and optional aft lavatory, supporting business charter missions and owner-flown long-range trips. Avionics fit for this airframe follows the typical Citation X-era suite, commonly equipped with Honeywell Primus systems, supporting high-speed, high-altitude IFR operations. Typical missions for this airframe profile include transcontinental and point‑to‑point charters within the continental U.S. and offshore range sectors out to its 3,460 nm capability, flown from its owner’s base in Broomfield, Colorado. Maintenance and operation follow Type Certificate and manufacturer guidance for the AE3007C powerplants and Citation X systems, with mid-life refurbishments and component life limits as principal ongoing considerations.

The Cessna 750 Citation X family occupies the high-speed, long-range business jet niche among purpose-built corporate jets, notable for high cruise speeds near 528 kts and service ceilings around 51,000 ft. Competitive models in the same market segment include long-range light-to-midsize jets where buyers balance speed and operating economics; demand for Citation X examples is shaped by their performance and by lifecycle maintenance on the AE3007C engines. Resale and maintenance considerations for a 2003 airframe like N399LF commonly center on engine time, avionics upgrades from the original Honeywell Primus fit, and the overall interior condition in relation to its $5,100,000 market valuation.
