N63ES

The airframe bearing registration N63ES is a 1995-built Gulfstream G-IV-SP, manufacturer Gulfstream Aerospace, serial number 1261. It is registered in the United States to owner NICEAIR LLC, an LLC based in Polson, MT, US, which appears as the current recorded owner on the registry. The airframe has been presented in operator materials as a charter-configured jet, and registry notes indicate a maximum seating capability of 22; operational listings report a more typical commercial charter fit. There are no public notations of major historic incidents in the supplied data, and the aircraft’s configuration and avionics are consistent with continued business and charter operations.

This specific G‑IV‑SP is fitted with a three‑zone executive cabin layout, including forward and aft lavatories and a full aft galley, and is described on operator pages in a reported 14‑passenger charter configuration while the registry records seating capability up to 22. Avionics are listed as the Honeywell SPZ‑8000, a typical fit for GIV/GIV‑SP airframes, supporting long‑range IFR charter missions and coast‑to‑coast transcontinental flights consistent with the type’s performance. Based in Polson, Montana by owner registration, the aircraft’s mission profile would commonly include business group transport and on‑demand charter legs at medium to long range; maintenance considerations follow the G‑IV family norms for TAY‑powered airframes, including engine and APU support and avionics commonality.

The Gulfstream G‑IV‑SP occupies a mid‑to‑large business jet niche with transcontinental range and higher cruise speed relative to light jets, making it competitive against earlier Falcon 900 and Challenger 601 series types. With a certified ceiling of 45,000 ft, a cruise of 459 kts and a 4,091 nm range, it remains attractive for fractional owners and charter operators seeking intercity and international capability without moving into ultra‑long‑range types. Market considerations for this 1995 airframe include aging‑aircraft maintenance requirements, parts and engine support for the Rolls‑Royce TAY 611SER, and resale dynamics tied to cabin refurbishment and seating configuration (14–19 typical vs. 22 max reported).
