Figure 2-2. Hand Darning Method
(c) Zigzag Sewing. Airdrop 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 irregularly
shaped or have material missing, the repair will be achieved by either darning or patching, as required. A
zigzag sewing repair will be accomplished using a zigzag sewing machine, the specifics cited in Tables 2-2
and 2-3, and the following procedures.
1
Set the sewing machine to the maximum stitch width.
2
Beginning at a point ¼-inch (0.635 cm) beyond one end of the cut or tear, stitch lengthwise along the
damaged area to a point 1/4-inch (0.635 cm) beyond the opposite end of the cut or tear (A, Figure 2-3).
The cited stitching procedure will also apply to an L-shaped cut or tear (B, Figure 2-3).
3
If applicable, restencil informational data or Identification marks as prescribed In paragraph 2 8.c.
NOTE
Holes or tears that exceed 1-inch (2 54 can) in length or 1-inch (2.54
cm) in diameter will not be machine darned or hand darned.
However, any cut or tear may be repaired with zigzag stitching
provided no material adjacent to the cut or tear is missing.
Any hole or tear that exceeds 1-inch (2.54 cm) in length or 1-inch
(2.54 cm) in diameter will be patched.
