The public federal record on N4370Y, 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 Egan Tim, an individual, certificate issued March 21, 2025, expires March 31, 2032. No fractional interest recorded. [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 489548546 for this model in the deregistered file. [2]
N4370Y was previously assigned to 2 other aircraft: Piper PA-46-310P (serial 468408080, cancelled November 12, 1991); Piper PA-25-260 (serial 25-4853, cancelled April 15, 1969). 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]
