N159WW

This airframe, registered as N159WW, is a 1999-built Gulfstream G550, serial number 578. It is recorded in the U.S. registry and is listed as owned by WILLAS WINGS LLC of Prescott, AZ, US, reflecting a single corporate ownership entry in public records. The airframe configuration and registry data list a total of 20 seats, a figure noted in the registry that may differ from typical outfitting counts for the model. Aside from standard U.S. registration, no additional transfers or notable historical events are recorded in the supplied data.

The cabin for this specific G550 is described as an executive long‑range layout with a typical outfitting of 14–18 passengers, while the registry lists 20 seats, indicating a possible variance between certified seating and common interior configurations. Avionics are fitted with Gulfstream PlaneView, supporting long-range business missions and modern navigation/communication requirements. Based from Prescott, AZ, US under ownership of WILLAS WINGS LLC, the aircraft’s performance envelope and fuel capacity make it suited to transcontinental and intercontinental point-to-point executive transport consistent with a 6,750 nm range and high cruise speed. Maintenance and operational considerations for this airframe would follow Gulfstream and Rolls-Royce support practices typical of BR710-powered G550s, with attention to long‑range mission systems and executive cabin preservation.

The Gulfstream G550 family occupies the long‑range large‑cabin business jet market niche, offering a high cruise speed of 488 kts and a maximum operating ceiling of 51,000 ft, enabling extended non‑stop routes and favorable en route performance. Primary competition comes from other ultra‑long‑range large-cabin types; market demand historically favors well‑maintained, avionics‑current airframes like those equipped with Gulfstream PlaneView. Buyers and charter operators place premium value on documented ownership history, engine model and hours, and interior condition—factors that directly influence maintenance planning and resale prospects for a 1999 serial 578 airframe.
