Who can pack, maintain, or alter the auxiliary parachute of a single harness dual parachute pack?

The correct answer is that only an appropriately certificated and type-rated parachute rigger can pack, maintain, or alter the auxiliary parachute of a single harness dual parachute pack. This requirement is in place to ensure safety and compliance with aviation regulations.

Parachutes are complex devices that require a deep understanding of their mechanics and appropriate packing techniques to function safely and effectively. A certificated rigger has undergone specialized training and testing that equips them with the knowledge necessary to handle parachute systems securely. This includes understanding the specific design and operational characteristics of different parachute types, including auxiliary parachutes.

Having a skilled rigger pack or maintain the parachute ensures that it is done correctly, minimizing the risks associated with parachute malfunction during a jump. The complexities involved with such tasks, including the discrepancies between various parachute designs and the precise handling techniques required for safe operation, underscore the importance of using qualified personnel.

This level of responsibility cannot be entrusted to anyone without proper certification and type rating, as doing so could lead to dangerous situations or accidents.
