Which packing interval is required for an approved parachute to be eligible for emergency use?

• A. 180 days
• B. 90 days
• C. 365 days
• D. 60 days

Answer: (A)

Regular repacking of an approved parachute is required to ensure it will deploy reliably in an emergency. The packing interval for an emergency parachute is 180 days, meaning it must be repacked (and inspected by a qualified parachute rigger) at least every six months. This interval is set because the fabric, lines, and knots can deteriorate, loosen, or suffer damage over time, and periodic repacking includes a thorough check for wear, moisture exposure, UV damage, and proper stowage. Keeping the parachute within this six‑month window helps ensure it will function correctly when needed.

Shorter intervals (like 60 or 90 days) would add unnecessary maintenance without providing proportional safety benefits, while a full year (365 days) risks undetected deterioration. The 180‑day cycle represents a practical balance between safety and maintenance practicality.
