The public federal record on N4256, 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 Castleberry Robert F, an individual, certificate issued June 7, 2024, expires June 30, 2031. 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 SL-1 for this model in the deregistered file. [2]
No other airframe has carried N4256 according to the deregistered file. [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 N4256. 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.
AD compliance against the logbooks and flight-activity reconciliation are researched layers of the full report.
