The public federal record on N9156C, 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 Oconnor Dallas, a co-owned, certificate issued November 14, 2002, expires October 31, 2028. No fractional interest recorded. [1]
Restricted certificate for agriculture and pest control, dated June 10, 1993, consistent with the 1993 manufacture year. [1]

N9156C was previously assigned to 1 other aircraft: Cessna 180 (serial 31255, cancelled January 12, 1955). 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 N9156C. CLEAR means the query ran and returned nothing, not that nothing ever happened. [4]
