NOTE
Both the upper and lower portions of the orifice edge reinforcement
may be spliced once per gore.
REPAIR
Splice a damaged orifice edge reinforcement as follows:
1. Place the canopy on the repair table with the damaged area up; smooth the area around the damaged
orifice edge reinforcement.
2. If only the orifice edge reinforcement is damaged, cut a length of type III, nylon tape, long enough to
extend 4-inches beyond each side of the damaged area. Sear the ends of the tape. Center the tape
over the damaged area, and stitch according to the original construction and Table 2, WP 0012 00.
3. If damage to the orifice edge reinforcement extends into gore section(s), and requires replacement of
the section(s), place the canopy on the repair table, smooth the damaged area, and pin the section(s)
to the table. Be sure the radial and diagonal seams are straight. Cut the orifice edge reinforcement,
close to the radial seams (or radial and diagonal seams) that border the damaged area. Cut a length
of type III, nylon tape, long enough to extend 4-inches beyond each radial seam (or each radial seam
and diagonal seam) involved. Sear the ends of the tape. Baste the 4-inch ends of the tape in place.
Replace the gore section(s) adapting procedures in WP 0036 00. Use the tape as a guide for
trimming the edge of the new section(s). Turn-under the raw edge ½-inch, and stitch the tape in place
using the same sewing machine, thread, and stitch range as specified in step 2., above.
