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. This is how the Diamond Aircraft DA 40 Diamond Star family is built; the FAA does not record construction for each aircraft, and the type certificate data sheet is the authority for this one.
