- Built of
- steel tube, wood and fabricA 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 biplane of the 1920s and 1930s: steel-tube fuselage, wooden wings, fabric covering. This is how the Waco CSO 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 N671N, 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.
Registration status is "N-number assigned, not registered, pending cancellation". An aircraft cannot be operated on an invalid or expired registration; resolve this with the FAA before any transaction. [1]
Standard certificate; the FAA file gives no certificate date and no manufacture year. [1]
No earlier tail number is recorded against serial 3140 for this model in the deregistered file. [2]
No other airframe has carried N671N according to the deregistered file. [2]
No bills of sale, loans or releases have reached the registry in recent weeks. The index covers only recent filings; older liens are in the records file. [3]
No NTSB investigation records located under N671N. CLEAR means the query ran and returned nothing, not that nothing ever happened. [4]
These live in the FAA aircraft records file (every document ever filed against the aircraft) and, for larger aircraft, the International Registry. Part of the full report.
AD compliance against the logbooks and flight-activity reconciliation are researched layers of the full report.
