Do Unused Parachutes Need Repacking? Frequency and Importance
Do Unused Parachutes Need Repacking? Frequency and Importance
The necessity of repacking unused parachutes, even if they have never been deployed, cannot be overstated. Whether used for skydiving, military missions, or other aerial operations, regular repacking ensures safe and reliable deployment. This article will explore the guidelines for repacking frequency, the reasons behind it, and industry practices observed in real-world scenarios.
Frequency Guidelines
According to industry standards, unused parachutes should be repacked periodically:
For most types of parachutes, especially those used in skydiving: Every 180 days (6 months). For military and some specialized parachutes: Every 12 months, though this can vary based on specific regulations and usage.Reasons for Repacking
Moisture and Contamination
Over time, moisture can accumulate in the parachute, leading to mold or mildew which can degrade the fabric and lines. Contaminants like dust and oils can also affect performance, necessitating thorough repacking to prevent these issues.
Regular repacking allows for a careful inspection of the parachutes' lines and fabric. This helps to identify any wear, fraying, or damage that may have occurred since the last packing, ensuring that the parachute remains in optimal condition.
Proper Deployment
Regular repacking ensures that the parachute is packed correctly, which is crucial for reliable deployment. An improperly packed parachute can lead to malfunctions during descent, putting the user at significant risk. Proper packing is the foundation of safe operation.
Regulatory Compliance
Many aviation and skydiving organizations have strict regulations regarding parachute maintenance to ensure safety. Adhering to these guidelines is not only important for compliance but also for maintaining the highest standards of safety and performance.
Real-World Experience
A Real-World Case Study: The Navy Parachute Loft
My first job out of boot camp was in a US Navy parachute loft. Here, unused parachutes were repacked every 90 days. Parachutes were circulated through a distribution center, with student pilots drawing a chute for each flight and returning it afterward. Instructors had assigned chutes. The base used various types, such as backpacks for T28s and chest chutes for SNBs (Navy Airboats).
My role involved collecting chutes to be inspected and repacked, hanging them to dry, and assisting with the packing process. To open the chutes, we needed to pull the ripcord handle, which required significant force. However, everyone accomplished this task smoothly.
Consistency is Key
The US Navy's strict repacking schedule of every 90 days is a testament to the importance of regular maintenance. Chutes were not repacked more than once every three months to ensure optimal condition and reliable performance.
Industry Best Practices
Following the repacking frequency guidelines is crucial for ensuring that parachutes operate safely and effectively. For most types of parachutes, the maximum time between packing and repacking should be every 180 days. Chutes that have not been repacked in this time are at a significant risk of not opening properly, which can lead to severe consequences.
Conclusion
In conclusion, the repacking of unused parachutes is a critical component of maintaining safety and performance. Whether used for recreational skydiving, military operations, or other aerial activities, adhering to the recommended frequency guidelines is essential. Regular repacking helps prevent moisture and contamination, ensures line and fabric integrity, and guarantees proper deployment. Complying with these practices aligns with industry standards and regulatory requirements, making them a non-negotiable part of parachute maintenance.
