5. Darning. Darning is a sewing procedure used to repair limited size holes, rips, and tears in assorted
airdrop items constructed from textile material. A darning repair may be made either by hand or
sewing machine, depending upon the method preferred and the availability of equipment. Refer to
WP 0012 00, and use the following guidelines.
A darning machine should be used to darn small holes and tears
where fabric is missing.
a. Darning small holes or tears. Darn small holes or tears in the main panel, reinforcement panel,
side flaps, paddle pocket locking stow panel, suspension line protector cover, and locking stow
loop hood if the holes or tears do not exceed ¾-inch in length or diameter. Use size E, nylon
thread, and 7 to 11 stitches per inch.
b. Darning previously patched material. Darning of previously patched material can be performed
provided the darning size limitations prescribed in step a., above, are not exceeded.
c. Machine darning. Proceed as follows:
Using an authorized marking aid of contrasting color, mark a square around the damaged
area and ensure the marking is at least ¼-inch back from each edge of the damaged area.
Darn the damaged area by sewing the material in a back-and-forth manner.
Turn the material and stitch back and forth across the stitching made in procedure 2.,
above, until the hole or tear is completely darned.
If applicable, restencil informational data, gore number(s), or identification marks in
accordance with WP 0014 00.
6. Patching. Patch holes in the suspension line protector cover that exceed ¾-inch in length or diameter.
Proceed as follows:
