An Airworthiness Certificate remains valid as long as the aircraft is maintained and alterations are performed according to the regulations set forth by the FAA. This means that regular maintenance checks, compliance with any airworthiness directives, and adherence to repair and alteration protocols are essential to keep the certificate in good standing. If an aircraft is not maintained properly or if significant alterations are made without proper guidance, the certificate may be rendered invalid.

While it may seem that an Airworthiness Certificate could be indefinite, it is contingent upon ongoing compliance with maintenance standards, hence why the correct understanding emphasizes the necessity of regulatory conformity. The idea that it is valid until the aircraft is sold or only for a year after issuance reflects misconceptions about the nature of the certificate's validity—it is specifically tied to active compliance and maintenance status rather than these arbitrary timeframes or ownership changes.
