N554SL

This airframe, registered as N554SL, is a 1998-built Gulfstream G-IV with serial number 1343 manufactured by Gulfstream Aerospace. The jet is recorded as owned and operated by STEWART AVIATION SERVICES LLC, an Alabama-based LLC located in Birmingham, AL, US, and is registered in the US. Condition and valuation records indicate an estimated market value of $5,800,000, with typical executive outfitting and aftermarket variations affecting individual airframe condition and equipment baselines. Currently carrying US registration and operated from Birmingham, Alabama under corporate ownership.

The cabin for this Gulfstream G-IV is described as a typical executive layout with a forward galley and options for forward and aft lavatories; it is certified for up to 22 seats but is commonly fitted for 12–16 executive passengers. Avionics fit on this airframe is typically the Collins Pro Line 4, though aftermarket suites and panel upgrades vary by individual airframe and operator configuration. Operationally the jet’s long-range capability of 4,220 nm and cruise speed of 460 kts support transcontinental and near-transoceanic executive and charter missions from its Birmingham base. Maintenance considerations reflect the G-IV family’s twin Rolls-Royce Tay powerplants and the logistics of keeping avionics and interior refurbishments current to sustain charter and corporate marketability.

The Gulfstream G-IV occupies a long-range large-cabin business jet niche, offering high cruise speed and transcontinental range relative to mid-size competitors. Competing models typically include later Gulfstream variants and large-cabin types from Bombardier and Dassault; resale value and buyer demand hinge on interior condition, avionics modernization such as the Collins Pro Line 4, and engine maintenance status for the Rolls-Royce Tay 611 pair. At an estimated value of $5,800,000, this airframe’s marketability will depend on documented maintenance, interior configuration, and any prospective upgrades to avionics or cabin amenities.
