a. Repair. 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 1/2 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. Replacement. Replace a damaged riser extension tie loop or tie strap by fabricating using the following
procedures, as applicable:

Remove a damaged tie loop by cutting the loop material at a point adjacent to the stitch
formation located on each end of the loop.
Cut a length of 1-inch wide, type XVII nylon webbing long enough to extend 1/2 inch beyond
the stitch formation located at each end of the original loop. Sear the webbing ends.
Center the webbing length in the original loop location with the ends extending over the original
loop stitch formations by 1/2 inch. Secure each end of the webbing by stitching according to
original construction details. Stitching will be made with a heavy-duty sewing machine using
size 3 nylon thread, 5 to 8 stitches per inch.
(2) Riser extension tie strap.
Cut and remove a suitable amount of stitching that secures each end of the tie strap between
the corners of the riser extension cover and the bag horizontal end strap.
Remove the tie strap by cutting the stitch formations which secure the strap to the bag
horizontal end strap.
Cut a 22-inch length of 1 -inch wide, type XVII nylon webbing and sear the ends.
