RESEARCH NOTES
About N15Y
Compiled with AI assistance from the public sources listed below, November 2025. Not checked against the aircraft's logbooks.
Overview
This entry covers the Gulfstream airframe bearing registration N15Y, a production Gulfstream G-IV (G-IV SP) completed in 1997 with manufacturer serial number 1318. The airframe is recorded as owned by Apa Stream LLC, an LLC based in New York, NY, US, and is registered to the United States. Current ownership by Apa Stream LLC is the principal documented change in the aircraft’s registry history available in the supplied data. No additional public valuation or condition history is provided for this specific airframe.
Operations & Cabin
The cabin on this airframe is configured in an executive layout and certificated for up to 22 seats, arranged with forward and aft service/galley areas and a lavatory; the internal fit is described as operator-configurable. Typical mission profiles for an airframe with a 4,220 nm range and 460 kts cruise speed include transcontinental and North Atlantic crossings or high-capacity executive transport on medium- to long-range sectors. The twin Rolls-Royce TAY 611-series engines provide the thrust necessary for sustained high-altitude operations up to 51,000 ft, a capability commonly exploited on higher-altitude, fuel-efficient cruise profiles. The operator base is noted as New York, NY, and operations from that hub would support heavy use on coast-to-coast or international charter and corporate missions.
Model & Market Context
The Gulfstream G-IV (G-IV SP) family occupies the large-cabin, long-range business jet niche, offering higher range and cabin capacity compared with mid-size types while competing with late-model Gulfstream variants and long-range offerings from Bombardier and Dassault. With a certificated capacity up to 22 seats on this airframe, demand tends toward corporate shuttle and high-capacity executive roles as well as charter operators seeking transcontinental capability. Prospective buyers and operators typically weigh the airframe’s age (built 1997) against maintenance history, avionics fit, and engine cycle life for the Rolls-Royce TAY series when considering acquisition or resale.
