The public federal record on N400EF, 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 Bye Aerospace INC, a corporation, certificate issued June 26, 2026, expires June 30, 2033. No fractional interest recorded. [1]
No airworthiness certificate is on file. Usual for a newly registered aircraft, a project, or an aircraft that has not flown since a change of registration; ask for the certificate. [1]
No earlier tail number is recorded against serial 0001 for this model in the deregistered file. [2]
N400EF was previously assigned to 1 other aircraft: Gates Learjet Corp. 35A (serial 561, cancelled July 13, 2005). 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 N400EF. 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.
AD compliance against the logbooks and flight-activity reconciliation are researched layers of the full report.
