What is required regarding the conditions of the AD for a certified rigger before they may pack a parachute?

The correct choice highlights that the conditions stated in the Airworthiness Directive (AD) permit further operation, which is essential for a certified rigger to ensure that they are compliant with safety regulations and standards. When an AD is issued, it typically contains specific instructions or conditions that must be followed to ensure the continued airworthiness of the equipment, in this case, parachutes. If the AD provides guidelines that allow for further use or operation, it indicates that the rigging process, including packing the parachute, can continue as long as those conditions are met.

Understanding the framework set by an AD is crucial for certified riggers as it provides them with the necessary legal and safety context under which they can perform their duties. Not adhering to these directives could lead to safety hazards, legal issues, or loss of certification, making it imperative for riggers to stay informed about current ADs and their contents.
