What should be done when the actions required by an AD are completed?

When the actions required by an Airworthiness Directive (AD) are completed, it is essential to document the completion in the aircraft records. This documentation serves several critical purposes.

Firstly, it ensures compliance with regulatory requirements, demonstrating that the operator has addressed the airworthiness concern as specified by the AD. Regulatory bodies require thorough record-keeping to track compliance and safety measures taken on an aircraft.

Secondly, having a documented record of completed AD actions provides crucial information for future maintenance and inspection activities. It offers a detailed history of what has been performed on the aircraft, which can be important for current and future operators, maintenance personnel, and during audits or inspections by aviation authorities.

Lastly, maintaining accurate records fosters accountability and reliability, as all parties involved in the operation and maintenance of the aircraft can reference the documented actions taken in response to airworthiness directives. This is vital for the ongoing safety and operational integrity of the aircraft.
