The public federal record on N789, 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.
Valid registration to Alaska Aviation Museum, a corporation, certificate issued July 9, 2012, expires July 31, 2028. No fractional interest recorded. [1]
Standard certificate; the FAA file gives no certificate date. [1]
No earlier tail number is recorded against serial B-102 for this model in the deregistered file. [2]
N789 was previously assigned to 1 other aircraft: Douglas M-3 (serial 622, cancelled January 2, 1930). Histories keyed to the tail number alone can mix aircraft up; this check keys on the serial number. [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 N789. CLEAR means the query ran and returned nothing, not that nothing ever happened. [4]
