N503UP

This airframe, registered as N503UP, is a 2003-built Cessna 560XL Citation Excel with serial number 560-5326. The airframe is owned by the corporate operator WHEELS UP PARTNERS LLC, based in New York, NY, and registered in the United States. The airframe matches the mid-life population of Citation Excels from the early 2000s and carries a typical operator fit and registry history for a corporate fleet aircraft; ownership under a well-known membership charter/management company is the defining recent change in its provenance. There are no public indications of unusual damage history or extraordinary valuation adjustments beyond normal market influences for its model year and configuration.

The cabin of this airframe is laid out in a typical mid-size configuration with club seating and a mix of forward- and rear-facing arrangements, configured to accommodate up to 13 passengers for short‑to‑medium‑range missions. Avionics are installed in the common Honeywell Primus suite associated with Excel/XLS operator fits, though specific panel and optional equipment can vary by operator. With a cruise speed of 441 knots and a range near 1,858 nautical miles, the aircraft is routinely used for cross‑country corporate flights, membership charter legs, and business shuttles from its New York base; maintenance follows the standard type‑certificate and operator programs for the 560XL. As a corporate‑owned airframe, it typically operates under structured maintenance and tracking regimes appropriate for fleet aircraft, which supports predictable dispatch reliability and charter availability.

The Cessna 560XL Citation Excel occupies the mid-size, light-to-midsize business jet niche, offering higher speed and cabin comfort than light jets while remaining less complex and costly than larger cabin class types. Competing models include the Learjet 60XR, Embraer Legacy 450/500 family, and older Gulfstream/Gulfstream-shrunken types in charter and owner-operator markets. With twin PW545 engines producing 3,952 lbf each and a service ceiling of 45,000 feet, the airframe balances performance and operating economics; resale and charter demand for Excel-series airframes remains steady among buyers seeking a blend of range, speed, and cabin capacity without the acquisition and operating costs of larger heavy jets.
