Why are Airworthiness Directives (ADs) issued by the FAA?

Airworthiness Directives (ADs) are issued by the FAA primarily to address and correct unsafe conditions that have been identified in aviation components, systems, or aircraft. When a potential safety issue is discovered—whether through the routine monitoring of aircraft performance, reported incidents, or new information from manufacturers—the FAA assesses the risk involved. If they conclude that a defect or unsafe condition poses a significant risk to safety, an AD is published to mandate specific actions that must be taken, such as inspections, repairs, or modifications to ensure the safety of the aircraft.

This regulatory mechanism ensures a proactive approach to aviation safety, compelling owners and operators to rectify issues promptly, thereby maintaining a high standard of safety within the aviation industry. The issuance of ADs is a critical part of ensuring that all aircraft continue to meet safety standards throughout their operational lives.
