How To Repack A Parachute: A Master Rigger's Step-by-Step Guide

Repacking a parachute requires meticulous attention to detail, adherence to strict manufacturer specifications, and a controlled, clean workspace. Whether you are maintaining a skydiving rig, an emergency reserve, or a tactical deployment system, following a standardized technical inspection and packing cycle ensures peak deployment reliability and life-saving performance.

Pre-Operation & Equipment Checklist

Executing a safe and legally compliant repack workflow demands a designated packing area free of moisture, abrasive debris, and direct UV exposure. For certified civilian emergency reserves and sport skydiving rigs, operations must adhere to Federal Aviation Administration (FAA) Part 65 standards or equivalent international civil aviation authorities, executed under the supervision of an appropriately rated FAA Senior or Master Parachute Rigger.

• Essential Gear and Tools: Packing table or specialized smooth packing floor, lead weight or packing bags, pull-up cords (minimum two high-tensile nylon lines), temporary packing pins (straight and bent), tension-locking tool or brake pullers, digital or analog scale for pull-force verification, and an inspection logbook.
• Prerequisite Knowledge and Standards: Comprehensive familiarity with the specific container and canopy manufacturer owner manuals, understanding of container closing loops, and certified authorization or direct supervision under a licensed rigger.
• Time and Environmental Benchmarks: Allocate approximately 60 to 90 minutes for a meticulous inspection and pack job. Ensure relative humidity in the packing space remains below 65 percent to protect nylon fabrics and lines from moisture degradation.

Step-by-Step Rig Inspection and Packing Workflow

Step 1: Complete Component Airworthiness Inspection

Spread the canopy and harness-container system completely on the packing floor to execute a thorough 100-point physical inspection. Examine every inch of the suspension lines, bridle, pilot chute, deployment bag, and container grommets for fraying, chemical contamination, UV damage, or broken stitching.

1. Inspect all suspension lines sequentially from the connector links down to the canopy attachment points, checking for snagged or pulled threads.
2. Verify that the closing loops, particularly the main activation and reserve container closing loops, show no signs of excessive abrasion or core slippage.
3. Check the condition of the ripcord assembly or reserve static line (RSL) to ensure uninterrupted mechanical travel and secure hardware attachment.

Warning: Never pack a parachute that shows structural damage, grease contamination, or excessive wear on the suspension lines. Damaged components must be replaced immediately with manufacturer-approved parts.

Step 2: Canopy Flaking and Suspension Line Organization

Gather the canopy by the connector links or control lines and flake the fabric cleanly to establish symmetrical folds before packing. Proper flaking guarantees that deployment forces distribute evenly across the canopy surface, mitigating the risk of line-over malfunctions or hard openings.

1. Flake the nose and tail sections alternately, pulling the leading edge clean and bringing the stabilizers together down the centerline.
2. Carefully pull the suspension lines down toward the container, ensuring that lines A, B, C, and D remain completely clear of twists and separate freely from the connector links to the cascade points.
3. Flake the lower half of the canopy and perform the traditional "S-fold" or rolling technique to ready the fabric for placement into the deployment bag.

Pro-Tip: Use weighted bags or lead shot bags to hold down flaked canopy panels securely on the packing surface as you work your way up to the apex.

Step 3: Placing the Canopy into the Deployment Bag

Fit the prepared canopy securely inside the deployment bag while maintaining consistent tension on the suspension lines to prevent premature line dump during the initial extraction phase.

1. Dress the flaked canopy into the deployment bag cleanly, keeping the apex centered and avoiding any bunching of fabric in the corners.
2. S-fold the remaining tail and fabric neatly into the top of the bag, tucking the material underneath the deployment bag flap or locking tabs.
3. Stow the excess suspension lines securely using the rubber bands or stow channels on the deployment bag, leaving only enough line exposed to reach the container cleanly without slack.

Step 4: Securing the Container and Final Pin Insertion

Place the packed deployment bag into the main or reserve container tray and systematically route the closing sequence according to the manufacturer manual.

1. Position the pilot chute and bridle correctly within the top of the container tray, checking that the spring or collapsible mechanism operates without binding.
2. Route the closing loop through the container grommets sequentially—typically starting from bottom to top or following the designated 1-2-3-4 pin sequence.
3. Insert the temporary packing pin through the closing loop to secure the flaps under tension, then carefully seat the pilot chute and close the final main container flap.

Common Inspection Failures and Field Fixes

• Root Cause: Suspension line twists discovered during the flaking process.
  
  
  • Actionable Fix: Disconnect the affected lines at the links (if permitted) or meticulously walk the twists out back to the canopy hem to guarantee a straight, untangled deployment path.
• Root Cause: Frayed or fuzzy closing loops threatening premature failure during pin pull.
  
  
  • Actionable Fix: Discard the worn loop immediately and tie a brand-new closing loop to exact factory-specified length using approved cordage.
• Root Cause: Excessive humidity or moisture exposure detected within the canopy fabric.
  
  
  • Actionable Fix: Hang the canopy in a climate-controlled, well-ventilated room out of direct sunlight for 24 hours to completely dry the nylon before attempting any packing procedures.

Frequently Asked Questions

How often does a parachute need to be repacked?

Emergency and reserve parachutes must be inspected and repacked by a certified rigger every 180 days, regardless of whether they have been deployed. Main parachutes used in sport skydiving do not have a legally mandated calendar limit in many jurisdictions, but rigging best practices recommend regular inspection and maintenance every 30 to 60 days.

Can a skydiver pack their own main parachute?

Yes, in many jurisdictions, a licensed skydiver with a valid rating is legally permitted to pack their own main parachute. However, reserve parachutes must always be packed by a certified parachute rigger due to the critical nature of emergency deployment systems.

What causes a hard opening during parachute deployment?

Hard openings are typically caused by improper slider placement, a loose closing loop, incorrect packing techniques that allow the canopy to de-furl too rapidly, or excessive deployment airspeeds. Ensuring the slider remains fully up against the canopy skirts and verifying proper line stowage prevents this issue.

Why is zero-porosity nylon critical for parachute canopies?

Zero-porosity nylon limits air permeability through the fabric, ensuring that internal pressure builds rapidly upon deployment. This controlled pressurization creates a stable, predictable glide angle and reliable opening characteristics.
