How often must the Certificate of Airworthiness be re-validated?

The Certificate of Airworthiness must be re-validated once a year to ensure that an aircraft remains in a condition for safe operation. This annual re-validation process typically involves a thorough examination of the aircraft to ensure it complies with the applicable safety standards and regulations set forth by the aviation authority.

Regular re-validation not only confirms the physical airworthiness of the aircraft but also serves as a preventive measure to catch any potential issues that could compromise safety before they develop into more significant problems. The annual requirement is a standard practice in aviation to maintain safety and reliability.

While maintenance activities may influence the validity of the airworthiness certificate, it is the annual requirement that is a consistent and fundamental part of aviation regulations for ensuring that all aircraft remain safe to operate throughout their operational lives.
