N513LS

This airframe, registered as N513LS, is a Gulfstream IV built in 1991 with manufacturer serial number 1178. The airframe is recorded as owned by SPEC AIR LLC, based in Saint Petersburg, FL, US, and is registered in the US civil registry. The aircraft’s recorded valuation is $3,500,000, and public records do not indicate additional prior owners or transfer events; current ownership is held by SPEC AIR LLC. As a 1991 Gulfstream IV, this airframe represents a mature, well-documented corporate transport with typical registry history for aircraft of its vintage.

The airframe is certificated for 22 passengers, while typical executive layouts for the Gulfstream IV are cited as accommodating 13–14 passengers in three cabin sections configured with a forward galley, mid-cabin seating area, and an aft lavatory; this reflects the certificated capacity versus common VIP interior fits. Operator base activity would be centered on Saint Petersburg, FL, US, consistent with the listed owner location. Typical mission profiles for this airframe include long-range corporate transport and transcontinental or intercontinental charters within the aircraft’s 4,220 nm range capability and high-speed cruise of 459 kts. Maintenance considerations for this specific airframe are consistent with the Rolls‑Royce Tay 611‑8 engine type and airframe age; detailed avionics fit or specific in-service configurations for N513LS are not published in the provided data.

The Gulfstream IV family occupies the large-cabin, long-range corporate jet niche, offering transcontinental range and high cruise speeds suitable for executive transport missions such as those this airframe performs. Competitors in the same performance bracket include late-model large-cabin business jets offering similar range and passenger capacity. Given the 1991 build year and the $3,500,000 valuation, resale and maintenance outlooks typically reflect age-related refurbishment, engine program status, and interior reconfiguration potential relative to market demand for vintage long-range business jets.
