N188SA

The airframe bearing tail number N188SA is a Gulfstream IV (G-IV) built in 1990 with manufacturer serial 1150. It is recorded as owned by Alliance Aviation Group LLC, a limited liability company based in Wilmington, DE, US, and is registered in the US. The airframe underwent a notable interior refresh and was fitted with an executive cabin in 2003, and its reported market valuation is $2,950,000, reflecting its age, systems fit and refurbishment history.

This specific Gulfstream IV (G-IV) is configured in a refurbished 2003 executive layout accommodating up to 13 passengers: a forward four‑place club, a mid three‑place divan opposite a two‑place club, and an aft four‑place conference group; the interior also includes a forward crew lavatory, an aft lavatory, and a full aft galley. The airframe carries a Honeywell SPZ 8000 avionics suite equipped with HUD/EVS, TCAS 7.1, TAWS, and dual UNS-1LW FMS, enabling precision long‑range operations and enhanced situational awareness for crew. Typical mission profiles for this configuration would include transcontinental and transoceanic executive transport within the type’s long‑range capability, operated from the owner’s Wilmington, Delaware base for corporate or charter duties. Maintenance considerations for this airframe center on older-generation Rolls‑Royce Tay engines and systems lifecycle items tied to its 1990 manufacture date, though avionics and cabin updates mitigate operational obsolescence.

The Gulfstream IV (G-IV) occupies a long‑range, large‑cabin business jet niche with a cruise speed around 459 kts and intercontinental range near 4,220 nm, competing with late‑generation Bombardier Challengers and early Global Express variants for mission flexibility. Buyer and charter demand for well‑equipped, refurbished G‑IVs typically emphasizes cabin finish, avionics modernization and engine condition; resale values like $2,950,000 reflect market depreciation for 1990 airframes balanced against upgrades such as HUD/EVS and a 2003 executive interior. Prospective operators weigh maintenance timelines for the Rolls‑Royce Tay engines and component life‑limits against the platform’s proven operating economics and cabin capacity.
