The public federal record on N104CK, 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 Connally Douglas R, an individual, certificate issued April 28, 2024, expires April 30, 2031. No fractional interest recorded. [1]
Experimental certificate for amateur built, dated July 12, 2023, consistent with the 2023 manufacture year. [1]

N104CK was previously assigned to 1 other aircraft: Lockheed L-1011-385-1-15 (serial 193N-1193, cancelled September 2, 2009). Histories keyed to the tail number alone can mix aircraft up; this check keys on the serial number. [2]
