How often must a chair-type parachute be packed by a certificated rigger?

Chair-type parachutes must be packed by a certificated rigger at least every 120 days to ensure their reliability and safety during use. This requirement is in place to maintain the integrity of the parachute system, as factors such as humidity, degradation of materials, and wear and tear can affect performance. Regular inspections and repacking by a qualified rigger help to mitigate any risks associated with parachute deployment.

The timeframe of 120 days strikes a balance between operational readiness and the need for thorough inspection and maintenance, ensuring that parachutes remain in optimal working condition. This standard is crucial for both recreational and professional skydivers who depend on their equipment for safety.
