What are the privileges of a certificated Senior Parachute Rigger related to parachute maintenance?

The privileges of a certificated Senior Parachute Rigger primarily include the ability to pack and maintain parachutes, but do not extend to performing major repairs on any type of parachute. Therefore, the correct choice highlights that they may pack or maintain any parachute except for major repairs.

In terms of parachute maintenance, "packing" refers to the process of folding parachutes in a specific way so they deploy correctly during use, while "maintaining" generally involves routine inspections and repairs that do not reach the level of major repairs, which might include structural changes or significant alterations.

Understanding the limitations of a Senior Parachute Rigger is crucial for safety and compliance with aviation regulations, ensuring that all equipment is suitable for operation while adhering to the established safety standards. This distinction emphasizes the responsibility that comes with the privilege of parachute rigging and highlights the importance of having different tiers of certification for various levels of expertise and tasks within parachute maintenance.
