Built of
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. The Mite: an all-wood single-seater under fabric. This is how the Mooney M-18 family is built; the FAA does not record construction for each aircraft, and the type certificate data sheet is the authority for this one.

The public federal record on N4121, read the way a buyer, lender or insurer reads it: FAA registration, prior tail numbers keyed on the serial number, reuse of the tail number, recent registry filings, and the NTSB accident record under this and every earlier registration.
