a. Restitching. Stitch and restitch broken or loose stitching with size 3 nylon thread which matches the
color of the original stitching, when possible. Lock all straight stitching by backstitching at least 112 inch.
Restitch by overstitching each end of the stitch formation by 1/2 inch. Restitch directly over the original
stitching, following the original stitch pattern as closely as possible. Stitch according to para. 2-19 and table 2-3.
b. Splicing. A vent line hole reinforcement may be spliced an unlimited number of times as follows:
A vent line hole reinforcement is located on both the outside and the inside of the
end panel at the bridle end of the bag.
Cut a length of 1 23/32-inch wide, type XII nylon webbing long enough to extend 1 inch beyond
each side of the damaged area and sear the ends.
Center the webbing length over the damaged area and, if required, fold the webbing to conform
to original construction details. Secure the full length of the splice by stitching according to
original construction details. Stitching will be made with a medium-duty sewing machine using
size E nylon thread, 5 to 8 stitches per inch.
