N429SA

This airframe, registered as N429SA, is a Gulfstream G-IV (G‑IV SP) built in 1998 with manufacturer serial number 1314. It is recorded as owned by SUPERIOR AMBULANCE AVIATION INC, a corporate owner based in Elmhurst, IL, US, and is entered on the US civil register (US). The airframe’s age and corporate air-medical ownership suggest operational use tailored to long-range passenger or special-mission work; valuation and condition summaries are Not published. No other public registry actions or prior ownership transfers are provided in the supplied data.

The cabin for this Gulfstream G‑IV airframe is listed as a typical executive layout accommodating 14–19 passengers, though the exact interior can vary by installation and mission fit. Avionics are reported as Honeywell SPZ‑8000 / SPZ‑8400, depending on cockpit upgrade status, which supports modern navigation and communications appropriate for long-range, high‑speed operations. With a mission radius enabled by a 4,220 nm range and cruise of 460 kts, the aircraft is capable of transcontinental or long overwater sectors, consistent with corporate transport or dedicated air‑ambulance deployment by its Elmhurst‑based operator. Maintenance requirements will reflect the airframe’s 1998 manufacture date and the two Rolls‑Royce RB.183 Tay (611 series) turbofan engines, with lifecycle and component support influencing operating availability.

The Gulfstream G‑IV (G‑IV SP) occupies a high‑end long‑range business jet niche characterized by high cruise speed, significant payload for its class, and transcontinental capability as demonstrated by this airframe’s 460 kts cruise and 4,220 nm range. Typical buyers and operators value the combination of cabin capacity (here 14–19 seats in executive form), established airframe maturity, and available avionics upgrade paths such as the Honeywell SPZ‑8000 / SPZ‑8400. Market and resale considerations for a 1998 serial 1314 airframe include the condition of the Rolls‑Royce RB.183 Tay (611 series) engines, avionics modernization level, and interior refurbishment status, all of which materially affect demand and operating economics.
