An Airworthiness Directive (AD) is a legally binding regulation issued by a national aviation authority (e.g., FAA in the US) to correct an unsafe condition in an aircraft, engine, propeller, or appliance. ADs mandate specific inspections, repairs, or modifications that must be performed within a certain timeframe to ensure the continued safe operation of affected aircraft. Compliance with ADs is mandatory for all operators.
