Airworthiness Directive

An Airworthiness Directive (AD) is an official notice issued by aviation safety authorities, such as the FAA or EASA, that mandates specific actions to address safety concerns in aircraft, engines, or parts. These directives are based on findings that identify potential risks or defects that could compromise safety. Operators must comply with ADs by inspecting, repairing, or replacing affected components within specified timeframes. Essentially, ADs serve as proactive safety measures to ensure aircraft remain safe to fly and maintain standards for all safety-critical parts throughout their operational life.
