N188SA1990 Gulfstream IV

Overview

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.

Operations & Cabin

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.

Model & Market Context

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. 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.
