N400ZU

The airframe bearing tail number N400ZU is a Gulfstream G‑IV series business jet built in 1986, carrying serial number 1009. This specific G‑IV is owned by EASTERN STEARMAN INC TRUSTEE (a corporate trustee) based in Leesburg, VA, US, and is registered in the US. The airframe is noted as certificated for up to 22 seats and carries a reported market value of $5,800,000, reflecting its mature age, classic G‑IV systems fit and mid-life maintenance status. Registry records for this airframe emphasize its corporate-trust ownership structure and the aircraft’s continued operation under U.S. registration; no public record of recent ownership transfers or notable incidents is provided in the supplied data.

The cabin is described as a typical executive Gulfstream layout with a forward galley, forward and aft lavatories, cabin length approximately 13.75 m, and width approximately 2.23 m, supporting common 13–19 passenger arrangements while being certificated for up to 22 seats. Avionics fit is the Collins Pro Line 4 suite, a common fit for G‑IV series aircraft that supports long‑range IFR operations and common business-aviation mission profiles such as transcontinental and transoceanic charters. Typical operations for this airframe would include extended-range executive transport and corporate shuttle missions consistent with the aircraft’s 4,220 nm range and 460 kt cruise speed, operating from the owner’s Leesburg, VA area base or similar corporate facilities. Maintenance considerations for this specific airframe reflect the G‑IV’s age: systems like the Pro Line 4 and Tay 611-8 engines require established support and life-limited component tracking.

The Gulfstream G‑IV/G400 family occupies the large-cabin, long-range executive jet niche, offering transcontinental and transoceanic capability in an airframe introduced in the 1980s. Competing models include late‑generation large-cabin types from Bombardier and Dassault of similar era and newer midsize/large-cabin jets in secondary markets. Buyer and charter demand for G‑IV airframes typically centers on value-conscious operators seeking large cabins and long range at modest acquisition cost; resale and maintenance considerations for this airframe include ongoing engine and avionics support for the Rolls‑Royce Tay 611‑8 powerplants and the Collins Pro Line 4 suite, as well as adherence to aging‑aircraft inspection regimes.
