Built of
composite
The airframe is composite: carbon fibre or glass fibre set in resin, moulded in large pieces with few joints, which gives smooth shapes but needs different inspection and repair methods from metal. Carbon-fibre fuselage and wings, the first airliner built mostly of composite. This is how the Boeing 787 Dreamliner family is built; the FAA does not record construction for each aircraft, and the type certificate data sheet is the authority for this one.
