N400RJ was previously assigned to 1 other aircraft: Beech 65-80 (serial LD-127, cancelled October 6, 2014). 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 N400RJ. CLEAR means the query ran and returned nothing, not that nothing ever happened. [4]
