N501RB

The airframe bearing tail number N501RB is a 1990-built Gulfstream G-IV (serial number 1138) manufactured by Gulfstream Aerospace. Owned by the corporation LONE STAR LAND & CATTLE CO of Houston, TX, US, the aircraft is recorded on the US civil register and is associated with a corporate operator profile based in Houston. The airframe's certification and registration actions are noted as United States registration; no additional lease or transfer history is provided. Valuation records list the aircraft at $3,000,000, which reflects its market position as an older, large-cabin business jet with ongoing operational life.

The configuration for this specific G-IV lists a seating capacity of 22, indicating a high-density or mixed-use interior layout tailored for corporate transport or group missions rather than ultra-luxury single-owner executive fit. Typical missions for this airframe profile include transcontinental and offshore operations within its 4,220 nm range capability and cruise performance around 460 kts, operated from the owner’s base in Houston. The twin TAY 611SER engines, each producing 13,850 lbf, support the aircraft’s long-range cruise and high-altitude capability to its 45,000 ft ceiling, factors that influence route planning and maintenance cycles. Specific avionics fit and cabin amenities are not published for this airframe; maintenance and refurbishment considerations for a 1990 Gulfstream G-IV generally center on airframe fatigue, avionics retrofits, and engine program status.

The Gulfstream G-IV family occupies a high-performance large-cabin business jet niche, offering long-range transcontinental capability and comfortable cabin capacity as reflected by this airframe’s 4,220 nm range and 22-seat arrangement. Competing models in similar missions include later-generation Gulfstream variants and long-range business jets from Bombardier and Dassault; however, the 1990-build date and listed value of $3,000,000 indicate notable depreciation relative to newer types. Prospective buyers and operators of this serial often weigh the cost of avionics modernization, engine life limits, and interior refurbishment against the platform’s proven aerodynamic performance and operational ceiling.
