The public federal record on N91945, 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 Marine Aviation Museum INC, a co-owned, certificate issued June 7, 2002, expires August 31, 2027. No fractional interest recorded. [1]
The airworthiness certificate on file is dated June 16, 1993, 41 years after the 1952 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]
No earlier tail number is recorded against serial 126882-SF85 for this model in the deregistered file. [2]
N91945 was previously assigned to 2 other aircraft: Cessna 182M (serial 18259965, cancelled June 26, 1970); Piper J3C-65 (serial 16365, cancelled February 24, 1956). 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]
