The public federal record on N999AT, 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.

ATTENTIONTail number reuse

N999AT was previously assigned to 1 other aircraft: Learjet Inc 45 (serial 494, cancelled February 14, 2020). Histories keyed to the tail number alone can mix aircraft up; this check keys on the serial number. [2]
