N583AJ

This entry covers airframe N583AJ, a Gulfstream G‑IV built in 1992 with manufacturer serial number 1184. The airframe is listed on the U.S. registry and is registered to KOT AVIATION LLC, an LLC based in Brea, CA, United States, which serves as the operator/home base for this airframe. Maintenance and registry records for this specific serial indicate continuous operation in the corporate charter/owner-operated sector. Notable listing references identify avionics entries under Honeywell SPZ series designations for this aircraft.

The cabin of this G‑IV is outfitted as a 13‑passenger executive configuration: a forward four‑place club, a mid two‑place club opposite a three‑place divan, and an aft four‑place conference/grouping, with forward and aft lavatories and an aft galley. Avionics fit for this specific airframe references Honeywell SPZ series (noted as SPZ‑8000 / SPZ‑8400 in listings) augmented by Collins navigation and communications components, supporting common corporate flight operations and long‑range IFR capability. Typical mission profiles for this installation would include intercontinental and transcontinental executive transport consistent with a 4,220 nm range and 460 kt cruise speed, operating from the owner/operator base in Brea, CA, United States. Maintenance considerations focus on airframe and engine program continuity for Rolls‑Royce Tay powered G‑IVs and avionics modernization paths tied to the SPZ/Collins architecture.

The Gulfstream G‑IV family occupies the large‑cabin, long‑range corporate transport niche, offering transcontinental performance and cabin comfort for up to thirteen passengers in this example. Competing models in its era and mission class include large-cabin jets from Bombardier and Dassault; buyer and charter demand for well‑maintained G‑IVs centers on proven range, cabin flexibility, and mature support networks. Resale and maintenance considerations for this airframe emphasize Tay engine programs, avionics upgrade potential from the SPZ series, and continuity of records for the 1992 serial 1184.
