Which document outlines the airworthiness directives (ADs) for an aircraft?

The correct document that outlines the airworthiness directives (ADs) for an aircraft is indeed found in the aircraft’s service bulletin. Service bulletins are issued by manufacturers and contain important information regarding aircraft maintenance, safety, and compliance with regulatory requirements, including airworthiness directives.

Airworthiness directives are legally binding regulations issued by the Federal Aviation Administration (FAA) or other aviation authorities that mandate certain maintenance or modifications to ensure the continued airworthiness of the aircraft. While the maintenance manual, pilot's operating handbook, and inspection report all contain essential information for the operation and upkeep of an aircraft, they do not specifically outline the airworthiness directives. Instead, the service bulletin is the document that provides the necessary updates and instructions that operators must follow regarding AD compliance. This link between service bulletins and airworthiness, specifically in the context of ADs, highlights the importance of these documents for maintaining safety and regulatory adherence in aviation operations.
