N537XX

This article describes a specific Bombardier Learjet 40XR airframe registered as N537XX, delivered in 2005 with manufacturer serial number 2022. The airframe is owned by 945HC LLC, an LLC based in Cypress, TX, US, and is registered in the US; no further prior owner history or notable registry actions are published in the provided data. The subject aircraft is valued at approximately $2,800,000 based on the supplied figure, reflecting its mid-2000s manufacture and typical market positioning for light business jets of its vintage.

The aircraft features a flat-floor executive cabin outfitted in an executive club seating arrangement for 6–7 passengers, a forward galley and an enclosed aft lavatory, consistent with the Learjet 40XR cabin specification. Avionics are listed as Honeywell Primus 1000 in typical fit; DU‑875/UNS‑1E upgrade options have been reported on similar airframes, which may affect navigation and flight-deck capabilities if installed on this specific serial. Typical mission profiles for this airframe include short- to mid-range executive transport within its 1,862 nm range and high-speed cruise at 436 kts, often used for business trips between regional hubs. Operating from its owner’s base in Cypress, TX, US, maintenance and operational considerations would align with Honeywell TFE731-20BR engine support and scheduled inspections typical for Bombardier light jets of this era.

The Bombardier Learjet 40XR occupies the light, high-performance end of the business-jet market, offering high cruise speed and a 51,000 ft ceiling relative to cabin size and range. Competing models include later light-cabin jets that emphasize either longer range or more modern avionics suites; buyer demand often targets operators valuing speed and climb performance over transcontinental range. Resale and maintenance considerations for this serial reflect age since 2005, engine model commonality (Honeywell TFE731 series), and any avionics upgrades such as the DU‑875/UNS‑1E if installed, all of which influence marketability and operating cost.
