Model & Market Context
The airframe bearing tail number N120JJ is a 1995 Gulfstream G-IV (G-1159A) built as serial 1264 by Gulfstream Aerospace Corporation. The airframe is recorded as owned by AVIATION SALES ASSOCIATES LLC, an LLC based in Costa Mesa, CA, US, and is registered in the United States; this transfer and current registration are notable events in the aircraft's limited public record. As a fixed-wing multi-engine business jet, N120JJ is presented with a market value of $3,000,000, reflecting its age, configuration and maintenance status at the time of valuation. The combination of serial, year and ownership places this specific G-IV within the later-production examples of the G-1159A family.
The cabin of this G-IV airframe is configured for up to 22 seats, consistent with high-density corporate or charter layouts that prioritize passenger capacity for medium- to long-range missions. Typical missions for N120JJ would encompass transcontinental and intercontinental routes within its 4,220 nm range at cruise speeds near 459 kts, operating from the owner/operator base in Costa Mesa and other regional business airports. Avionics fitment and specific interior appointments for this serial are not published in the provided data, but maintenance considerations center on the twin Rolls-Royce Tay 611-series engines and aging-system inspections typical of mid-1990s Gulfstream airframes. Operationally, the aircraft’s 45,000 ft ceiling supports efficient long-range cruise profiles and charter or corporate timetables requiring speed and altitude flexibility.
The Gulfstream G-IV (G-1159A) family occupies a performance niche as a large-cabin, long-range business jet introduced to serve transoceanic corporate missions with a balance of speed, range and passenger capacity. Competing models in its era and secondary market include earlier Gulfstream types and large-cabin competitors offering similar mission capability; buyers often compare lifecycle costs and avionics modernisation needs. For an airframe like N120JJ, resale considerations hinge on engine status, interior refurbishment and avionics upgrades; with a listed value of $3,000,000, prospective purchasers weigh maintenance cycles for the Tay 611-series engines and the cost of bringing cabin and systems to current standards.
