N999NB

This airframe, registered as N999NB, is a 1994-built Gulfstream G-IV(SP) constructed by Gulfstream Aerospace with constructor serial number 1234. The aircraft is registered in the US and is listed under the corporate owner STOCKHAM CONSTRUCTION INC, located in Cotati, CA, US.

Notable registry actions or valuation history beyond the current registration are not published in the supplied data.

The subject airframe, N999NB, configured with 22 seats, reflects the higher-capacity cabin layout typical of Gulfstream G-IV(SP) long-range business transports; specifics of the interior finish, exact cabin layout or avionics fit are not published in the provided dataset. With a certified ceiling of 45,000 ft and a long-range capability of 4,220 nm, typical mission profiles for this airframe would include transcontinental and extended offshore hops from its base in Cotati, CA, US, operating under corporate flight operations. Maintenance considerations for this specific aircraft follow those of the G-IV(SP) platform—particularly engine care for the twin Rolls-Royce Tay 611-8 powerplants—while records of recent inspections, modifications or refurbishments are not provided.

The Gulfstream G-IV(SP) occupies a long-range business jet niche, offering high cruise speed (459 kts) and extended range suitable for intercontinental corporate travel; in this case the airframe’s 4,220 nm range and 45,000 ft ceiling underline that capability. Competitors to the G-IV(SP) historically include later-generation large-cabin business jets that target similar transcontinental missions, and buyers often weigh acquisition and maintenance costs of older airframes (this example being a 1994 serial 1234) against upgrade or refurbishment requirements. Resale and operator demand for a corporate-registered G-IV(SP) such as N999NB tend to be influenced by maintenance history, interior condition and engine hours on the Rolls-Royce Tay units, details of which are not published in the supplied data.
