The public federal record on N4425S, 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 Andreini Linda J, a co-owned, certificate issued July 31, 2015, expires July 31, 2028. No fractional interest recorded. [1]
Experimental certificate for exhibition, dated December 1, 1998, consistent with the 1997 manufacture year. [1]

N4425S was previously assigned to 1 other aircraft: Air Tractor Inc AT-301 (serial 3010085, cancelled September 7, 1989). 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 N4425S. 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.
