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. A motor glider. This is how the Diamond Aircraft HK 36 family is built; the FAA does not record construction for each aircraft, and the type certificate data sheet is the authority for this one.
