N406JS

This entry covers the specific Gulfstream airframe registered as N406JS, a 1999-built Gulfstream G-IV(SP) with manufacturer serial number 1394. The aircraft is owned by G4 LEASING STRATEGIES LLC, an LLC based in Kinston, NC, US, which serves as its operator/home base. The airframe carries a US registration and its documented configuration and avionics reflect retrofit activity such as a DU-885 display upgrade; no separate public record of additional registry events or valuation changes is provided here. Condition highlights are limited to the described 13-passenger executive interior and the installed avionics/engine combination that define its operational capability.

The cabin of this G-IV(SP) is configured in a 13-passenger executive layout featuring a forward dual three-place divan, a mid four-place conference group, and an aft two-place club opposite a single club seat with ottoman, complemented by an aft galley/refreshment center. Avionics fit for this airframe is documented as a Honeywell SPZ-8400 with a DU-885 plane deck (DU-885 upgrade noted), autothrottle PZ-800, and systems including TCAS 7.1, ADS‑B (V2), and FANS 1/A+, enabling modern ATC communication, surveillance, and reduced crew workload. Typical missions for this airframe model and configuration would exploit its long-range (4,220 nm) and high cruise speed (459 kts) for transcontinental and some transoceanic executive transport missions originating from its Kinston, NC base. Maintenance considerations for this specific airframe would focus on the health and supportability of the Rolls‑Royce TAY 611‑8 engines and the upgraded Honeywell avionics suite.

The Gulfstream G-IV(SP) represented in this airframe occupies a performance niche as a long-range, high-speed business jet with transcontinental capability and a high-service-ceiling of 45,000 ft. With twin Rolls‑Royce TAY engines delivering 12,450 lbf thrust each and a 13-seat executive cabin, the type appeals to buyers and charter operators seeking a mix of speed, range, and cabin capacity. Resale and maintenance considerations for this airframe hinge on engine cycle exposure, avionics upgrades such as the DU-885 and ADS-B/FANS compliance, and the condition of the bespoke executive interior, all of which materially affect operational availability and marketability.
