1. Restitching. Restitch vertical tape. Using a light-duty sewing machine and size E nylon thread of
contrasting color, stitch over original pattern, 7 to 11 stitches per inch. Lock each row of stitches two-
inches at each end. When vertical webbing stitching has failed and section separation from vertical
webbing has occurred at the leading or trailing edge of ring slots, the repair will be accomplished as
a. Restitch failure in accordance with original construction. Sew a double throw zig-zag stitching across
the width of vertical webbing at leading/trailing edge of ring slot. Zig-zag stitching should be centered
on width of reinforced hem of leading/trailing edge and will be stitched in accordance with WP 0012
00, SEWING PROCEDURES.
b. As an option, if a zig-zag sewing machine is not available, a box stitch pattern (double row stitching at
box ends) 11/4-inches in length may be used. Box should start on reinforced hem of leading/trailing
edge, approximately 1/8-inches from edge of ring, and proceed in length along radial seam of ring.
2. Splicing. Splice damaged vertical tape as follows:
a. Place canopy on a repair table with damaged side of vertical tape facing up and smooth out canopy
material in affected area.
The vertical tape may be spliced an unlimited number of times.
b. Cut a length of ½-inch wide type III nylon tape, long enough to extend 6-inches beyond each side of
damaged area and sear ends as specified in WP 0013 00, SEARING AND WAXING.
