How often is the summary of Airworthiness Directives published?

The summary of Airworthiness Directives (ADs) is published annually. This annual publication compiles and summarizes all the ADs that were released during the previous year, providing aviation maintenance personnel and organizations with essential updates on regulations that may affect aircraft design, operation, and maintenance. This annual summary is crucial for ensuring compliance and keeping abreast of safety requirements in the aviation industry. The other options suggest more frequent or less frequent publications, which do not align with the established schedule for AD summaries. Understanding this timing ensures mechanics stay informed about necessary actions and compliance related to aircraft safety.
