N138SP2000 Cessna Citation X

Overview

This entry documents the individual airframe N138SP, a Cessna 750 Citation X built in 2000 with serial number 750-0138. The airframe is owned by Fixed Gear 2 LLC, a corporate owner based in Seattle, WA, US, and is registered in the US registry.

Operations & Cabin

The cabin of this airframe typically conforms to an 8-12 executive layout with double-club seating, a forward galley and options for an aft lavatory, and this specific aircraft is fitted to accommodate 12 seats in line with that executive configuration. Avionics for the airframe are consistent with the Honeywell Primus-era fit common to 2000-series Citation X examples, though later avionics upgrades for individual aircraft are possible and not specifically recorded here. Operating from a corporate base in Seattle, WA, the aircraft’s performance, long range and high cruise speed, suits transcontinental business missions and higher-altitude, high-speed point-to-point executive transport. Maintenance considerations for this serial include the AE3007C engine family support and typical Citation X airframe systems, with corporate ownership implying managed maintenance programs rather than an airline-style regime.

Model & Market Context

The Cessna 750 Citation X occupies a performance niche as a high-speed, long-range executive business jet within Textron Aviation’s lineup, delivering transcontinental capability with a service ceiling of 51,000 ft and cruise near 525 kts. Competing models in the market historically include other ultra-long-range or high-speed large-cabin business jets; buyer demand for early 2000s Citation X airframes is influenced by airframe condition, engine cycles on the AE3007C engines, and available retrofit/avionics upgrade paths.
