The public federal record on N4977E, 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 Wyllie Ashton R J Trustee, an individual, certificate issued September 15, 2018, expires September 30, 2028. No fractional interest recorded. [1]
The airworthiness certificate on file is dated August 1, 1983, 32 years after the 1951 manufacture year. A re-issued certificate commonly follows export and re-import, a rebuild, or a return to the register after cancellation. The cause is documented in the FAA aircraft records file, which the full report obtains. [1]
No earlier tail number is recorded against serial 254 for this model in the deregistered file. [2]
No other airframe has carried N4977E according to the deregistered file. [2]
1 document received recently: Bill of sale (evidence of ownership) (September 29, 2026). [3]
No NTSB investigation records located under N4977E. 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.
