steel tube, wood and fabric
A welded steel-tube fuselage and wooden wings, all covered in fabric: the construction of the 1930s and 1940s, which makes wood rot and fabric age the inspection items. A glider of wood and fabric, with a steel-tube fuselage frame on some versions. This is how the Bowlus BA-100 family is built; the FAA does not record construction for each aircraft, and the type certificate data sheet is the authority for this one.
