(1)
Stitching. Using heavy duty sewing machine, stitch and restitch 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 directly
over the original stitching, following the original stitch pattern as closely as possible.
(2)
Restencil. As required, restencil identification marking using procedures in paragraph 2-19.
(3)
Splicing. Each of the two riser straps and the spreader bar may be spliced one time as follows:
NOTE
Splicing will be performed on a left riser when the damaged area extends into the parachute
inspection data pocket (log record pocket). When this occurs, a log record pocket from
stock will be installed in this location in accordance with procedures in paragraph 2-32.
(a)
Cut a length of type VI nylon webbing long enough to extend 2 inches beyond each side of damaged
area and sear ends (para. 2-18).
(b)
Center webbing length over damaged area (figure 2-54). Using a heavy duty sewing machine and size 3
nylon thread, secure each end of splice by stitching a single-X-box-stitch formation, with two double
ends, 1/8 inch in from each side edge of splice material. Overstitch each end of splice material by one
stitch on each point of stitch formation. Stitching shall be 5 to 8 stitches per inch.
