N779XZ

This article describes a single airframe registered as N779XZ, a Boeing widebody completed in 2020 bearing manufacturer serial number 65800. The airframe was built by the Boeing Company and is owned by Boeing Co (a corporation based in WA, United States) and is registered in the US. The aircraft has remained in manufacturer ownership and has been used in test and cabin systems development rather than in commercial airline service. Notable registry actions include its designation and maintenance as a manufacturer test asset rather than transfer to an operator or lessee.

The airframe carries a passenger interior installed in a test/cabin configuration, described as a roughly 130-seat test layout used specifically for cabin systems testing rather than a line-fit airline configuration. Its mission profile is therefore focused on systems validation, cabin systems integration, and in-service emulation flights operated from a manufacturer base in the United States. Avionics and operational fit are retained in a test and development standard appropriate to Boeing test operations rather than a commercial airline fit; maintenance cycles and airworthiness processes follow manufacturer test-asset procedures. Because the airframe is configured for test work, its usage emphasizes flight-test sorties, cabin systems trials, and related ground support rather than revenue passenger service.

The airframe is a member of the Boeing 777-9 family, a modern widebody platform positioned for long-range, high-capacity operations with advanced engines and aerodynamic features. With twin GE9X engines rated at 105,000 lbf each and a range of 7,285 nm, the type competes in a market niche against large twin-aisle models offering enhanced fuel efficiency and passenger capacity. Buyer and charter demand for production 777-9 airframes centers on major carriers and large cargo operators; resale and maintenance considerations for this test airframe are shaped by its non-standard cabin fit and manufacturer ownership, which affect conversion costs and time-to-entry for commercial service.
