NOTE
Two methods of stitching are used when repairing and replacing the
suspension line attachment loop. The stitching used when performing
these functions will match those used in the original construction of the
parachute.
REPAIR
Stitch and restitch (WP 0012 00, SEWING PROCEDURES) with size 3 nylon thread that matches the color of
the original stitching, when possible, if the suspension line attachment loop is sewn with a 3-point WW stitch
formation. Stitch and restitch with size FF nylon thread that matches the color of the original stitching, when
possible, if the suspension line attachment loop is sewn with zig-zag stitch formation. Lock all zig-zag
stitching by overstitching at least ½-inch. Restitch directly over the original stitch pattern, following the original
stitch pattern as closely as possible.
REPLACE
Replace an unserviceable suspension line attachment loop by fabricating as follows:
1. Remove the original suspension line attachment loop by cutting the stitching that secures the loop at the
canopy skirt.
2. Cut a 27-inch length of type IV nylon webbing and sear the ends (WP 0013 00, SEARING AND
WAXING).
3. Using a marking aid, mark the webbing at 33/4, 83/4, 131/4, 173/4, 223/4, and 263/4-inches from one end.
Fold the webbing at the 131/4 mark. This allows one end to extend ½-inch beyond the other.
4. Between the two marks that are 5-inches apart, fold the edges of the webbing toward the center of the
webbing.
