The public federal record on N5121Y, 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.

N5121Y was previously assigned to 1 other aircraft: Piper PA-23-250 (serial 272153, cancelled October 15, 1981). 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 N5121Y. CLEAR means the query ran and returned nothing, not that nothing ever happened. [4]
