Zig-Zag Sewing. (Refer to Tables 2-2 and 2-3). Air delivery items, except the canopy, made from textile
materials that have sustained cut or tear damage may be repaired by zig-zag sewing provided the applicable damaged

point 1/4 inch beyond the opposite end of the cut or tear (A, figure 2-38). The cited stitching procedure will also apply to
an L-shaped cut or tear (B, figure 2-38).
