Records check free · 2 to understand · 3 clear

The public federal record on N121R, 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.

CLEARRegistration and identity

Valid registration to Herzog Contracting CORP, a corporation, certificate issued May 9, 1991, expires May 31, 2027. No fractional interest recorded. [1]

ATTENTIONAirworthiness certificate date

The airworthiness certificate on file is dated April 18, 1979, 36 years after the 1943 manufacture year. A re-issued certificate commonly follows export and re-import, a rebuild, or a return to the register after cancellation. The cause is documented in the FAA aircraft records file, which the full report obtains. [1]

CLEARPrior registrations of this airframe

No earlier tail number is recorded against serial 75-5510 for this model in the deregistered file. [2]

ATTENTIONTail number reuse

N121R was previously assigned to 1 other aircraft: Aeroflite Autogyro DGH-1 (serial 1, cancelled May 18, 1965). Histories keyed to the tail number alone can mix aircraft up; this check keys on the serial number. [2]

NOTERecent registry documents

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]

CLEARAccident and incident record

No NTSB investigation records located under N121R. CLEAR means the query ran and returned nothing, not that nothing ever happened. [4]

PENDINGTitle chain, liens and 337 forms

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.

PENDINGAirworthiness directives and utilization

AD compliance against the logbooks and flight-activity reconciliation are researched layers of the full report.
