The public federal record on N771W, 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 Kalmar Istvan, an individual, certificate issued June 17, 2021, expires June 30, 2028. No fractional interest recorded. [1]
Experimental certificate for amateur built; the FAA file gives no certificate date and no manufacture year. [1]
No earlier tail number is recorded against serial NB375 for this model in the deregistered file. [2]
N771W was previously assigned to 1 other aircraft: Ogden S J Iii/Gorgas H L Iii VANS RV-4 (serial 3531, cancelled December 12, 1997). 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 N771W. 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.
