The public federal record on N4311Z, 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.

CLEARRegistration and identity

Valid registration to Weeks Kermit A, an individual, certificate issued June 27, 1991, expires August 31, 2027. No fractional interest recorded. [1]

ATTENTIONAirworthiness certificate

No airworthiness certificate is on file. Usual for a newly registered aircraft, a project, or an aircraft that has not flown since a change of registration; ask for the certificate. [1]

CLEARPrior registrations of this airframe

No earlier tail number is recorded against serial 11-880-202 for this model in the deregistered file. [2]

ATTENTIONTail number reuse

N4311Z was previously assigned to 2 other aircraft: Piper PA-28-181 (serial 2890070, cancelled August 11, 1988); Piper PA-18-150 (serial 18-8621, cancelled February 8, 1968). Histories keyed to the tail number alone can mix aircraft up; this check keys on the serial number. [2]
