Detailed inspection of the reserve parachute is the most critical part of the repacking process. If a defect is overlooked at this stage, the rest of the work becomes irrelevant. This is not just a visual observation; it is a systemic check that guarantees the system will not fail you in a high-stress situation.
Here is an in-depth and extensive overview of the inspection phase:
1. Canopy Inspection
The canopy is your "aerial brake." Any small hole can turn into a major tear under the pressure of airflow.
The "Backlighting" Method: This is the only way to find micro-damages. You must pass each fabric panel between a strong light source (such as a window or a lamp) and your eyes. The light will reveal structural irregularities, needle punctures, or areas worn out by the sun.
Seam Control: Pay special attention to the points where the lines connect to the canopy. Check the integrity of the stitching—ensure no threads are broken or "frayed."
Foreign Objects: Ensure that no insects, sand, or plant debris are trapped within the fabric layers. Organic substances cause rot and chemical damage to the fabric.
2. Lines Inspection
The lines carry the entire load during the moment of deployment (Opening Shock). Damage to them means a collapse of the system.
Friction Burns: If the parachute was previously deployed or packed incorrectly, the lines may have rubbed against each other. Look for "hardened" or discolored areas—these are signs of burns, which cause the line to lose 50–70% of its strength.
Chemical Damage: Check the surface of the lines for stains. Gasoline, oil, or even acid left by insects decomposes the material from the inside.
Search for Knots: Ensure there are no small "parasitic" knots on the lines. Any knot on a line acts as a stress concentrator, and the line will snap exactly at that point during opening.
3. The Connection (Bridle & Hardware)
This is the "bridge" between the pilot and the parachute. If the bridge breaks, the parachute will fly away without you.
Bridle Condition: Check the integrity of the main connecting strap (Bridle). There should be no abrasions, which usually occur due to friction against the harness.
Shackle and Carabiner: If the connection is made with a metal shackle, check for micro-cracks or rust. Make sure the shackle screw is tightly fastened and secured with a plastic "O-ring" (stopper) so that it does not rotate and damage the strap.
Harness Attachment Points: Do not forget to check the spot on the harness where the parachute is attached. Ensure that the seams of the suspension system are in perfect condition.
Why is this stage decisive?
Inspection is the moment you "vow" that this equipment will work. While other stages of the repacking process (organizing, replacing elastics) are mechanical, inspection requires an analytical approach. A pilot who goes through this stage superficially puts their own life at risk.
