N137WS

This airframe, registered as N137WS, is a 1997-built Gulfstream G-IV(SP) with serial number 1307. The airframe is recorded as owned by CF AVIATION TRUST LLC TRUSTEE, a trust/LLC based in Wilmington, DE, US, and is registered in the US. The aircraft carries a valuation of $4,495,000 and is noted in operator listings as configured for 14 PAX charter use, reflecting an operator-driven interior and mission profile change from factory maximum seating.

The cabin is described as a typical 14-passenger executive layout with a forward crew lavatory, full aft galley, and aft passenger lavatory; the airframe is operator-configured for 14 PAX charter use rather than the maximum certified seating. Avionics fit includes FMS 6.1 with WAAS/LPV and FANS 1/A+ (CPDLC), and operator listings reference modern FMS and communications upgrades consistent with long-range charter operations. Typical missions for this configuration include transcontinental and offshore charter flights within the aircraft’s approximately 4,220 nm range and high-speed cruise profile. Maintenance and operational considerations for this airframe reflect its age (manufactured in 1997) and the presence of upgraded avionics and operator-specific cabin refurbishments; these factors influence inspector focus on avionics integration, galley and lavatory systems, and lifecycle items for the Rolls-Royce TAY Mk 610-8 engines.

The Gulfstream G-IV(SP) family occupies a long-range, high-speed executive travel niche, offering transcontinental capability and a 45,000 ft service ceiling. Competitive comparisons typically include other late-1990s large-cabin bizjets offering similar range and speed; buyer and charter demand for well-maintained G-IV(SP) airframes remains driven by cabin condition, avionics upgrades, and engine maintenance status. Resale and maintenance considerations specific to this airframe include its 1997 manufacture date, trust ownership structure, operator-configured interior for 14 passengers, and the documented avionics/comm upgrade path.
