N450LR

This entry documents the specific Gulfstream IV airframe bearing tail number N450LR, a Gulfstream G-IV built in 1988 with manufacturer's serial 1013. The aircraft is registered US and currently owned by AVIATION COMPANY INC, a corporation based in Cheyenne, WY, US; the airframe’s ownership has remained under corporate registry without publicized fractional changes. Valuation records for this airframe list a current estimate of $3,000,000, reflecting its age, equipment fit and market position among late-1980s large-cabin business jets.

The airframe is typically outfitted in a 14-passenger executive cabin configuration while being certificated up to ~19–22 passengers, allowing flexibility for executive transport or higher-density charter operations. The installed avionics suite is listed as Honeywell SPZ-8000, though airframe-specific suites and upgrades can vary and affect dispatch reliability and modernization status. Operated from its owner’s home base in Cheyenne, WY, US, the aircraft’s mission profile is consistent with transcontinental and transborder executive missions; with a 4,216 nm range and a cruise of 459 kts, it supports long-haul nonstop sectors typical of Gulfstream IV operations. Maintenance considerations for this specific airframe reflect its late-1980s build year, avionics modernization choices and the twin Rolls-Royce Tay engines’ lifecycle programs.

The Gulfstream G-IV occupies a large-cabin, long-range niche, offering higher passenger capacity and range relative to smaller business jets of its era. Competing models historically include other long-range corporate jets from manufacturers offering similar transcontinental capability; buyer and charter demand for a 1988 G-IV is influenced by refurbishment level, avionics upgrades such as the Honeywell SPZ-8000, engine maintenance status and overall time-on-type. Resale and maintenance considerations for this airframe center on certified passenger capacity flexibility, legacy-systems upkeep, and the impact of modernization on the listed market value of $3,000,000.
