What information do Airworthiness Directives (ADs) provide?

Airworthiness Directives (ADs) are essential regulatory documents issued by aviation authorities, primarily the FAA in the United States, to inform aircraft owners and operators about unsafe conditions found in specific aircraft, engines, propellers, or components. The main purpose of an AD is to ensure that these identified safety issues are addressed promptly and effectively through prescribed corrective actions.

Option B is correct because ADs provide public summaries that detail these unsafe conditions, emphasizing the necessity for compliance to maintain aircraft safety and airworthiness. They often outline what the problem is, identify the aircraft affected, and specify the required actions to mitigate the safety risks, which may include inspection, maintenance, or modifications.

The other options do not align with the primary focus of Airworthiness Directives. Summaries of mandatory pilot training, operational weather procedures, and passenger safety measures serve different regulatory and operational purposes within aviation but are not the focus or the content of an AD. ADs are specifically focused on addressing mechanical and safety issues that could compromise the integrity of aircraft operation.
