The public federal record on N146ET, 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.

The cause is documented in the FAA aircraft records file, which the full report obtains. [1]
No earlier tail number is recorded against serial HA3046 for this model in the deregistered file. [2]
No other airframe has carried N146ET according to the deregistered file. [2]
