Who holds the primary responsibility for compliance with Airworthiness Directives?

The primary responsibility for compliance with Airworthiness Directives (ADs) rests with the aircraft owner or operator. This is because the owner or operator is ultimately responsible for ensuring that the aircraft is maintained in a condition that meets regulatory standards for safety and airworthiness. Airworthiness Directives are legally enforceable regulations issued by the FAA that instruct aircraft owners and operators to take specific actions regarding maintenance, inspections, or modifications to correct identified safety issues.

While the FAA issues ADs and the manufacturer may provide additional guidance or support, it is the responsibility of the owner or operator to ensure that the directives are followed to maintain the airworthiness of the aircraft. The pilot in command is responsible for the safe operation of the aircraft during flight but does not hold the same level of responsibility for compliance with ADs as the owner or operator.
