Model & Market Context
This airframe, registration N98LT, is a Gulfstream G-IV SP manufactured by Gulfstream Aerospace with manufacturer serial number 1278. The aircraft is owned by 98LT LLC, a corporation based in Austin, TX, and is registered in the United States. Registered to 98LT LLC in Austin, TX, the airframe’s public registry history and notable previous operators are not published. Current valuation data lists the airframe at $5,800,000, reflecting its condition and market position within mature large-cabin business jets.
The aircraft carries an executive 12-seat cabin layout typical for this airframe, configured for corporate transport and long-range point-to-point missions. Specific avionics fit and interior certification details for this serial are not published, but the Gulfstream G-IV SP platform is commonly found with business avionics suites tailored for long-range IFR operations. Typical operations for this airframe include domestic and transcontinental flights originating from its owner’s base in Austin, Texas, executing missions that exploit the type’s long-range capability and high cruise speed. Maintenance for this airframe would follow Gulfstream-recommended heavy checks and engine shop visits for the Rolls-Royce Tay 611-8 powerplants, with attention to aging-airframe inspection items consistent with its market valuation.
The Gulfstream G-IV SP occupies a long-range large-cabin niche, offering transcontinental and intercontinental capability with a cruise speed near 459 kts and a practical range of 4,220 nm. Competing models historically include later-generation large-cabin business jets and long-range derivatives from Bombardier and Dassault; buyers seeking this specific performance often balance acquisition cost against operating age and inspection history. Resale and maintenance considerations for this airframe center on engine life, scheduled structural inspections, and interior refurbishment potential given the 12-seat executive configuration and the listed market value of $5,800,000.
