N121AP

The airframe bearing tail number N121AP is a 1994 Gulfstream G‑IVSP, serial number 1239, delivered as part of Gulfstream Aerospace Corporation's G‑IVSP production run. It is currently owned by CROSSLAND GLOBAL SKY LLC, an LLC based in Rogers, AR, US, and is registrered in the US. There are no additional public registry events listed here beyond the current ownership; the most readily available valuation places the airframe at $4,464,389, reflecting market and condition assumptions for a 1994 G‑IVSP.

The cabin on this G‑IVSP is described as a typical executive layout and commonly supports 12–14 executive passengers in a forward double‑club, mid divan and aft conference configuration while retaining certificated seating up to 22. Avionics fit varies by airframe but reported installations for G‑IVSP examples include Honeywell SPZ‑8000 IFCS, Collins communications/navigation suite and Rockwell Collins TDR‑94D Mode S transponder; the specific fitment on N121AP follows these typical G‑IVSP installations unless otherwise noted. Operated from its owner’s base in Rogers, AR, US, the aircraft’s range and cruise performance support transcontinental U.S. missions and long‑range executive charters or corporate transport. Maintenance considerations for this airframe would align with legacy Rolls‑Royce Tay powerplants and late‑model G‑IVSP avionics configurations.

The Gulfstream G‑IVSP family occupies the large-cabin, long‑range executive market niche, offering transcontinental capability with high cruise speeds and altitudes up to 45,000 ft. Typical competitors include other large-cabin business jets offering similar range and passenger capacity; demand is driven by corporate and charter buyers seeking cabin comfort and intercontinental reach. For a 1994 airframe such as N121AP, resale and maintenance considerations focus on airframe hours, engines (Rolls‑Royce Tay 611‑8) status, avionics retrofits, and overall refurbishment to match contemporary operator expectations.
