The public federal record on N478J, 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". 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; the FAA file gives no certificate date and no manufacture year. [1]
No earlier tail number is recorded against serial MK3X04 for this model in the deregistered file. [2]
No other airframe has carried N478J according to the deregistered file. [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 N478J. 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.
