d. Zig-Zag Sewing. (Refer to Tables 2-2 and 2-3). Air delivery items, except parachute canopies, made from
textile materials that have sustained cut or tear damage may be repaired by zigzag 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, using the following procedures:
(1) Set the sewing machine to the maximum stitch width.
(2) Beginning at a point 114-inch beyond one end of the cut or tear, stitch lengthwise along the damaged
area to a point 114-inch beyond the opposite end of the cut or tear (A, figure 2-34). The cited stitching
procedure will also apply to an L-shaped cut or tear (B, figure 2-34).
(3) If applicable, restencil informational data or identification marks as prescribed in paragraph 2-20.
