2. Other parachute items. Stitching and restitching on other parachute items constructed from cloth,
canvas, and webbing should be accomplished with thread that matches the color of the original
stitching, when possible. All straight stitching should be locked by backstitching at least ½-inch.
Restitching should be locked by overstitching each end of the stitch formation by ½-inch. Zig-zag
stitching does not require locking; however, zig-zag restitching should extend at least ¼-inch into
undamaged stitching at each end, when possible. Restitching should be made directly over the original
stitching; follow the original stitch pattern as closely as possible.
(Refer to Tables 1 and 2). Components of the T-10C/T-10D, except parachute canopy, that have sustained
cut or tear damage, may be repaired by zig-zag sewing, provided the applicable damaged area does not
have any material missing and the cut or tear is straight or L-shaped. Should the damaged area be irregular
shaped or have material missing, the repair will be achieved by either darning or patching, as required. A
zig-zag sewing repair will be accomplished using a zig-zag sewing machine, with the following procedures:
1. Set the sewing machine to the maximum stitch width.
2. Beginning at a point ¼-inch beyond one end of the cut or tear, stitch lengthwise along the damaged
area to a point ¼-inch beyond the opposite end of the cut or tear.
3. The cited stitching procedure will also apply to an L-shaped cut or tear.
