What is an Airworthiness Directive?

Understanding Airworthiness Directives

An Airworthiness Directive serves as an official alert to owners and operators of certified aircraft, informing them of a recognized safety issue within a specific aircraft model, engine, avionics, or another system that requires rectification.

An Airworthiness Directive (AD) is a legally enforceable notification issued by aviation authorities. It mandates specific modifications, maintenance actions, or inspections for an aircraft type to ensure or maintain airworthiness.

• Response to Safety Issues: ADs are typically issued in response to discovered safety issues and are based on ongoing aircraft performance monitoring and incident investigations.
• Compliance Requirement: Aircraft operators and owners must comply with these directives to maintain the airworthiness of their aircraft.
• Global Coordination: While issued by national aviation authorities, ADs often have international implications and are closely coordinated with other countries' aviation authorities and manufacturers.

Airworthiness Directives are a fundamental aspect of aviation safety, ensuring that all aircraft are maintained and modified as necessary to meet the highest safety standards.
