REPAIR
1. Restitching. Stitching and restitching made on parachute canopies should be accomplished with size E
nylon thread that is contrasting in color to the fabric being stitched or the original thread being restitched.
If contrasting color thread is not available, thread of matching color may be used, providing all other
specifications are met. Straight stitching and restitching should be locked by at least two-inches at each
end of a stitch row, when possible. Restitch directly over the original stitching and follow the original
stitch pattern as closely as possible.
2. Darning. Darn a hole or tear in a gore section that does not exceed ¾-inch in length or diameter as
prescribed in WP 0014 00, SEWING PROCEDURES, using size E nylon thread. Each gore section may
be darned three times.
3. Patching. Use a patch to repair holes that exceed ¾-inch in length or diameter using the sewn patch.

Limitations. The following limitations apply to the 100-foot cargo parachute.

The limitations prescribed for parachute canopy patching will be
stringently adhered to under all circumstances and without any
deviations.
NOTE
When repairing parachute canopies, cloth nylon, parachute, 1.6 Oz.,
type II (twill weave) or type III (ripstop nylon) may be used in lieu of each
other.
