Repair - Sewing Procedures (cont).
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 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, using the following procedures:
(1) Set the sewing machine to the maximum stitch width.
(2) Beginning at a point 1/4 inch beyond one end of the cut or tear, stitch lengthwise along the damaged
area to a point 1/4 inch beyond the opposite end of the cut or tear (A, figure 2-39). The cited
stitching procedure will also apply to an L-shaped cut or tear (B, figure 2-39).
(3) If applicable, re-stencil informational data or identification marks as prescribed in paragraph 2-19.
