N421QS

The airframe bearing tail number N421QS is a 2008-built Gulfstream G450 (GIV‑X), serial 4114, manufactured by Gulfstream Aerospace Corporation. The airframe is owned by NJI SALES INC, a corporation based in Oklahoma City, OK, US, and is registered in the United States under a US registration. The airframe’s corporate ownership and US registration mark the principal administrative ties and operating base for this specific G450. The aircraft’s valuation is listed at $11,000,000, reflecting market positioning for a 2008 G450 with the specified equipment set.

The cabin of this airframe is configured in a typical three‑zone executive layout and is commonly fitted for 12–14 pax, though it is certified to accommodate up to 22 seats depending on interior fit. Avionics are installed as Honeywell Primus Epic / Gulfstream PlaneView, with options for HUD and Enhanced Vision available in the G450 family; this airframe carries that installed avionics baseline. Operationally, the aircraft is suitable for transcontinental and long‑overwater missions consistent with its 4,350 nm range and high‑speed cruise of 459 kts, and its owner’s location in Oklahoma City, OK, US suggests regional corporate or charter operations based from that area. Maintenance considerations align with the G450’s twin Rolls‑Royce Tay powerplants and the support network for Gulfstream airframes.

The Gulfstream G450 (GIV‑X) occupies a mid‑to‑large cabin, long‑range business jet niche, offering high cruise speed, transcontinental range, and a 45,000 ft service ceiling. Competing models in the segment include later large‑cabin Gulfstreams and other long‑range types, with buyer and charter demand influenced by cabin size, avionics fit such as Honeywell Primus Epic / Gulfstream PlaneView, and engine support for the Rolls‑Royce Tay 611‑8C. Resale and maintenance considerations for this 2008 airframe, serial 4114, center on the aircraft’s maintenance history, avionics options, and overall condition as reflected in the stated $11,000,000 valuation.
