(g) Fold the raw edges of the cloth piece as follows:
Fold under the raw edges located adjacent to a lateral band and aline the folded edges with
the outside edges of the lateral band. Secure the alined edges to the applicable lateral band
Fold under the raw edges located along radial seams that have four rows of stitching and
aline the folded edges with the center of the radial seams. Secure the folded edges to the
radial seams with pushpins.
(h) Secure the situated replacement section cloth to the canopy material by basting along each of the
folded edges. Basting will be made according to the procedures in paragraph 2-19a.
Remove the pushpins from the edges of the replacement section and secure the section material to
the canopy inside by stitching, according to the details in figure 2-110. Use the stitching procedures
in paragraph 2-19b, with size E nylon thread, 7 to 11 stitches per inch.
Turn the canopy right side out and trim the raw edges of the section material to a point 1/2 inch from
the stitching made in step (i), above.
(k) On the canopy outside, stitch completely around the prepared area using the stitching criteria in step
Reposition the item(s) removed or laid aside in step (1)(b), above, in the original location(s) and
reattach each item to the canopy by restitching according to original construction details and
paragraph 2-19b. Use a light-duty sewing machine and size E nylon thread, 7 to 11 stitches per inch.
(m) Stencil informational data or other markings on the replacement section using the procedures in
(3) Modified gore section replacement. If a gore section that is located next to the lower lateral band on a
bias-constructed canopy does not have damage extending into a corner that is bounded by the lower lateral
band and a radial seam, the section may be replaced using a modified method as follows:
(a) When removing the damaged section, cut the section material diagonally across the corner. Allow
the corner material of the original section to remain intact and also allow a sufficient amount of
material to remain to preclude the replacement section overlapping the pocket band.
(b) Except for the procedure in step (a), above, complete the section replacement using the applicable
procedures outlined in paragraph b(2), above, and the details in figure 2-111.
When replacing a gore section on a bias-constructed canopy using the
modified replacement method, it is not necessary to remove the V-tab from
the radial seam located alongside the damaged section.
