a. The sewn patch. The primary method of applying a basic patch is by sewing. When using this
method of patching on a parachute canopy, the patch will be applied to the inside of the canopy
(the sewn patch is shown below). Apply a sewn patch as follows:
(1)
Place the canopy inside out on a repair table, smooth the fabric around the damaged area,
and secure the item to the table with pushpins. Do not pin the damaged area.
(2)
Using an authorized marking aid of contrasting color, mark a square or rectangle around the
area to be patched and insure that one side of the marked square is parallel to the wrap or
filling of the material.
(3)
Cut the damaged area fabric along the lines made in step (2), above. Further, cut the fabric
diagonally at each corner to allow ½-inch foldback in the raw edges.
(4)
Make a ½-inch foldback on each raw edge. Pin and baste each foldback to complete the
prepared hole. Basting will be performed using the procedures listed in the beginning of
this WP.
(5)
Using the same type of material as in original construction, mark and cut a patch 2½-inches
wider and longer than the inside measurements of he prepared hole.
(6)
Center the patch prepared material over the prepared hole and insure the wrap or filling of
each patch material matches the wrap or filling of the fabric being patched. Pin the patch
material in position.
(7)
Make a ½-inch foldunder on each edge of the patch material and baste the patch to the
prepared area. Basting will be performed using the procedures in this WP.
(8)
Remove the pushpins securing the canopy to the repair table and secure the patch by
stitching, using the applicable details in the illustration above and this WP. Make the first
row of stitching completely around the patch. Turn the canopy right side out and make a
second row of stitching around the prepared hole. Stitching will be performed in
accordance with this WP.
