RESEARCH NOTES

About N1624K

Compiled with AI assistance from the public sources listed below, November 2025. Not checked against the aircraft's logbooks.

Overview

This entry concerns airframe N1624K, a Gulfstream G-IV SP built in 2001, serial number 1457. The aircraft is listed as owned by the corporate entity 4KLA LLC based in Pittsfield, MA, US, and operates on a US civil registration (US). Acquired and operated by 4KLA LLC as a corporate executive transport, the airframe is presented in operator material with a 16-place executive cabin; specific public records of major registry actions or a published valuation for this airframe are not published. Condition highlights beyond the operator listing are not published.

Operations & Cabin

Operator listings show N1624K configured in a 16-place executive layout with forward and mid cabin seating, a full aft galley, and enclosed forward and aft lavatories, reflecting a typical long-range corporate interior for the type. Avionics are reported as the Honeywell SPZ-8000 suite in line with the typical Gulfstream G-IV/G-IV SP fit; the operator site notes that the specific avionics fit for this airframe is not published. With a design range of 4,091 nm and a cruise speed near 459 kts, missions for this airframe are consistent with transcontinental and short intercontinental executive transport from the operator’s base in Pittsfield, MA, US. Maintenance considerations follow the twin Rolls-Royce Tay 611-8 support environment and standard Gulfstream heavy-airframe inspection cycles; detailed maintenance status for this specific airframe is not published.

Model & Market Context

The Gulfstream G-IV SP occupies the long-range large-cabin corporate jet niche, offering transcontinental capability and a high cruise speed compared with midsize business jets. Typical competitors include late-model large-cabin types offering similar range and speed; buyer and charter demand for this model centers on operators seeking mature platform performance with established maintenance networks. Resale and operating considerations for this airframe reflect its 2001 build year and the need for continued Rolls-Royce Tay engine support and Gulfstream-type avionics and interior refurbishment cycles.
