What must a certificated parachute rigger verify before packing a parachute subject to an Airworthiness Directive?

The correct choice emphasizes the importance of verifying that the Airworthiness Directive (AD) permits further operation of the parachute in question. An AD is issued when a specific safety issue is identified, and it outlines the necessary actions that must be taken to ensure aircraft safety. Therefore, before packing a parachute affected by an AD, it is crucial for a certificated parachute rigger to confirm that the parachute is still considered airworthy and can be safely used in accordance with the directive.

This ensures compliance with aviation safety regulations and helps prevent potential hazards during parachute operations. Understanding and adhering to the guidelines set by an AD is paramount for the safety of both the parachutist and the aircraft.

The context of the other options adds valuable insight into the requirements for parachute rigging. While verifying that a Master Rigger has approved any deviations, confirming the type of parachute, or ensuring thorough inspections are all important aspects of parachute operations, the primary concern when dealing with an AD is ensuring that further operation is permitted.
