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 0012 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.
a. Sewn patches. There are two types of sewn patches authorized, the basic and miscellaneous. A
basic patch is used to repair damaged cloth when the affected area is no closer than 1-inch from a
radial webbing upper lateral band or lower lateral band. Should a damaged area be closer than 1-
inch to the cited areas, a miscellaneous patch will be made.
Sewn patches on the canopy will be applied to the inside and may be
square or rectangular in shape.
When a miscellaneous canopy patch is used, cut stitching and remove
or lay aside items that may interfere with patch application. Refer to
applicable item repair paragraph for proper procedures.
Using a marking aid of contrasting color, mark a square or rectangle around area to be patched
and ensure one side of marking square or rectangle is parallel to warp or filling of fabric.
