N4557N was previously assigned to 1 other aircraft: Boeing N2S-5 (serial 75-8600, cancelled October 2, 1951). 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 N4557N. CLEAR means the query ran and returned nothing, not that nothing ever happened. [4]
