Who is responsible for ensuring compliance with Airworthiness Directives (ADs)?

The owner or operator of an aircraft is responsible for ensuring compliance with Airworthiness Directives (ADs). This responsibility stems from the regulatory framework governing aviation safety, where ADs are issued by the Federal Aviation Administration (FAA) to address unsafe conditions that could affect the safety of the aircraft.

Owners and operators must monitor and comply with these directives to maintain the safety and airworthiness of their aircraft. They are tasked with ensuring that any required modifications or maintenance associated with an AD are completed in a timely manner. This compliance is crucial to uphold the standards set for safe operation and to prevent potential hazards.

While the manufacturer provides information and sometimes the necessary solutions to address the ADs, and the repair station performs the required maintenance or modifications, the ultimate responsibility lies with the owner or operator to ensure that their aircraft meets all regulatory requirements, including adherence to applicable ADs. The pilot in command, while responsible for the safe operation of the aircraft during flight, does not hold the accountability for maintaining compliance with ADs.
