N428KS

This entry covers airframe N428KS, a Gulfstream G-IVSP built by Gulfstream Aerospace in 1999 with manufacturer serial number 1360. The airframe is owned by SN 1360 LLC, an LLC registered in Wilmington, DE, US, and carries a US registration. Current public records do not disclose a multi-owner operational history or notable registry actions beyond its registration to the listed limited liability company. The airframe is conventionally valued at $5,800,000, reflecting its year, model, and typical configuration for late-1990s Gulfstream IVSP examples.

The airframe is fitted with an executive layout cabin that can typically accommodate around 13 to 22 passengers depending on interior refit; the specific installation for N428KS is cited as seating 22 in maximum executive arrangement. Avionics for the platform commonly feature the Collins Pro Line 4 suite, although installations vary by airframe and documentation indicates that avionics fits may not be identical across examples. Typical mission profiles for this range and speed include transcontinental and long overwater executive transport, leveraging a cruise speed near 460 kts and a maximum certified ceiling of 45,000 ft. Based at the owner’s registered location in Wilmington, DE, US, the aircraft’s operations and maintenance considerations follow the common support pathways for Rolls-Royce Tay–powered Gulfstream IVSP airframes.

The Gulfstream G-IVSP represents an upgraded variant within the G-IV family, offering extended range and payload capability relative to earlier G-IV examples. With a transcontinental range of 4,220 nm and high cruise speed, it competes with late-generation large-cabin business jets in the used market where buyer and charter demand target reliable, long-range executive transports. Maintenance considerations for this specific airframe include oversight of the twin Rolls-Royce Tay 611 engines and any airframe-specific avionics or interior refits; resale value near $5.8 million reflects both the airframe’s age (built 1999) and typical market depreciation for late-1990s large-cabin Gulfstreams.
