Who holds the primary responsibility for compliance with Airworthiness Directives?

The primary responsibility for compliance with Airworthiness Directives (ADs) lies with the aircraft owner or operator. This is because ADs are legally enforceable rules issued by the aviation authority to address safety issues based on conditions found in specific aircraft models, engines, or other aviation products.

Owners and operators must ensure that their aircraft remain in compliance with these directives to guarantee safety and the airworthiness of the aircraft. This entails not only understanding the specific requirements of each AD but also ensuring that any necessary repairs, modifications, or inspections are carried out in a timely manner. Failure to comply with these directives can lead to serious safety implications and could result in legal repercussions for the owner or operator.

While the aircraft manufacturer and aviation authorities such as the FAA are involved in the issuance of ADs and ensuring that they address pertinent safety issues, the ultimate responsibility for confirming compliance rests with those who operate or own the aircraft. Maintenance personnel may assist by performing the required work to address ADs, but they do so under the direction and responsibility of the owner or operator.
