The public federal record on N1971P, 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 Sebesta Kenneth D, an individual, certificate issued August 11, 2023, expires August 31, 2030. No fractional interest recorded. [1]
Standard certificate for utility, dated May 10, 2012, consistent with the 2011 manufacture year. [1]
No earlier tail number is recorded against serial 015 for this model in the deregistered file. [2]
N1971P was previously assigned to 1 other aircraft: Piper PA-18A (serial 18-4205, cancelled August 3, 1962). 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 N1971P. 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.
