N151SD

This airframe, registered as N151SD, is a 1994-built Gulfstream Gulfstream G-IV SP (G-IV-SP), constructor serial 1249. The aircraft is owned by Aviation Company Inc, a corporation based in Cheyenne, WY, US, and operates on the United States registry. Operator home-base activity and line operations reflect the corporate ownership; no notable registry actions published. The airframe's market valuation is recorded at $1,995,000, indicating mature asset condition consistent with its model year and typical G‑IV/SP market depreciation.

The cabin on this specific airframe follows a typical three‑zone executive layout, with configurations for 13–19 passenger arrangements common to the model; the installed fit indicates a corporate transport role focused on executive missions. Avionics for this airframe align with common GIV/GIV‑SP installations, including Honeywell SPZ‑8000 and Collins ProLine variants, supporting long‑range, high‑altitude operations and advanced navigation/communication capability. Typical mission profiles for N151SD would include transcontinental and transoceanic executive flights enabled by its 4,220 nm range and cruise at 459 kts, operating from its corporate base in Cheyenne and similar continental hubs. Maintenance considerations reflect Rolls‑Royce Tay engine support and airframe‑age systems updates typical for a 1994 Gulfstream SP variant.

The Gulfstream G-IV SP (G-IV-SP) occupies the long‑range, large‑cabin executive transport niche, offering higher cruise speed and altitude capability relative to many midsize business jets, exemplified by its 45,000 ft service ceiling. Competing models occupy overlapping mission envelopes but may differ in cabin volume or operating cost; buyer and charter demand for late‑model G‑IV/SP airframes is influenced by avionics modernization, engine shop visit cycles for Rolls‑Royce Tay units, and overall asset condition. Resale and maintenance considerations for this airframe center on documented owner/operator support, retrofit potential for avionics, and the recorded market value of $1,995,000 relative to fleet peers.
