N145RT

This entry describes Gulfstream G‑IVSP airframe N145RT, built in 2001 with manufacturer serial number 1439. The airframe is a factory-built Gulfstream G-IVSP (Gulfstream IV-SP) assembled by Gulfstream Aerospace and is currently registered in the United States; it is registered to TVPX Aircraft Solutions Inc Trustee with the trustee entity located in North Salt Lake, UT, US. The aircraft has been maintained as a 13‑place executive transport and listings for this airframe have emphasized its avionics and long-range capability. No additional public registry actions beyond the current trustee registration and standard U.S. registration data are included in the supplied record.

The cabin of N145RT is a 13‑place aft galley executive layout consisting of a forward 4‑place club, a mid 3‑place divan opposite a 2‑place club, and an aft 4‑place conference group opposite a credenza, configured for executive transport and charter missions. Avionics as reported include a PlaneDeck DU‑885 with Sperry SPZ‑8400 EFIS, Honeywell autopilot/flight guidance upgrades, triple Collins VHF communications, FANS over Iridium STC capability and ADS‑B Out capability, with additional detailed avionics items noted in listing specifications. Typical mission profiles leverage the airframe’s long range and high cruise speed for transcontinental or transoceanic point‑to‑point executive flights from its operator base in North Salt Lake, Utah, or other U.S. hubs. Maintenance considerations for this airframe would center on Tay 611‑8 engine programs and avionics STC currency given the FANS/Iridium fit.

The Gulfstream G‑IVSP sits in the large, long‑range business jet segment, offering high cruise speed and extended range that compete with models such as the Bombardier Challenger 604/605 and early Gulfstream G450 variants. Buyers and charter operators value the G‑IVSP for its combination of range (4,220 nm), speed (459 kts), and proven airframe systems, while resale and maintenance considerations typically focus on engine shop visit cycles for the Rolls‑Royce Tay series and the avionics upgrade status (notably FANS/Iridium and ADS‑B Out) which affect international dispatch capability and marketability.
