The public federal record on N50831, 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 Graf David R, an individual, certificate issued June 27, 2018, expires June 30, 2028. No fractional interest recorded. [1]
Experimental certificate for operating light-sport previously certificated; the FAA file gives no certificate date and no manufacture year. [1]

N50831 was previously assigned to 1 other aircraft: Cessna 150J (serial 15069583, cancelled April 5, 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 N50831. 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.
