The airframe is aluminium: sheet metal over a riveted frame, the way most aircraft have been built since the 1940s. The Duchess twin. This is how the Beechcraft 76 Duchess family is built; the FAA does not record construction for each aircraft, and the type certificate data sheet is the authority for this one.
