The public federal record on N505TA, 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.
Registration status is "Registration pending, pending cancellation". An aircraft cannot be operated on an invalid or expired registration; resolve this with the FAA before any transaction. [1]
Experimental certificate for amateur built, dated May 7, 2016, consistent with the 2016 manufacture year. [1]
No earlier tail number is recorded against serial C00427 for this model in the deregistered file. [2]
N505TA was previously assigned to 1 other aircraft: Airbus Industrie A300 B4-203 (serial 271, cancelled May 13, 2010). 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 N505TA. 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.
