RESEARCH NOTES
About N145RT
Compiled with AI assistance from the public sources listed below, November 2025. Not checked against the aircraft's logbooks.
Overview
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.
Operations & Cabin
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.
Model & Market Context
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.
