The public federal record on N250JK, 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 Konitz Thomas Lyle, an individual, certificate issued May 21, 2024, expires May 31, 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 CCK-1865-0014 for this model in the deregistered file. [2]
N250JK was previously assigned to 1 other aircraft: Kristich John FIREFLY (serial 10015, cancelled date not given). 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 N250JK. 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.
