This airframe, registered as N909JS, is a 2002-built Gulfstream G-IV (G-IV SP / G400) with manufacturer serial number 1488. The airframe is owned by Potomac Air LLC, a corporation based in Bethesda, MD, US, and carries a United States registration (US).

The airframe configuration supports up to 22 seats, indicating a high-density or corporate shuttle interior for the Gulfstream G-IV (G-IV SP / G400) platform rather than a sparse long-range VIP layout. Typical missions for this airframe profile include medium- to long-range point-to-point business or charter operations within the aircraft’s 4,220 nm range and cruise at 459 kts, operating from its operator base in Bethesda, MD, US. Avionics fit and specific cabin amenities for this serial 1488 airframe are not detailed in the provided data; maintenance considerations focus on the twin Rolls-Royce TAY 611-series powerplants producing 12,450 lbf each, which dictate scheduled engine inspections and support cycles for continued serviceability.

The Gulfstream G-IV (G-IV SP / G400) occupies a long-established position in the large-cabin, long-range business jet market, offering transcontinental capability with a service ceiling of 45,000 ft. Its performance niche compares with other late-model large-cabin jets offering similar ranges and cruise speeds, attracting buyers or charter operators seeking a combination of speed and passenger capacity; in this case the 22-seat fit emphasizes group transport. Resale and maintenance considerations for this platform center on engine support for the Rolls-Royce TAY series, avionics retrofits for older airframes, and market demand driven by operator needs for range, payload, and cabin configuration.
