There is no limitation to the number of patches or size of patch to each canopy gore section or gore
panel. However, determination should be made, of the most economical method to be used, i.e.,
two or more patches versus one large patch or one large patch versus a section replacement. A
patch applied to a parachute canopy may extend from radial seam to radial seam.
(b) Making a basic patch. A basic patch is used to repair damaged cloth when the affected area is no
closer than 1 inch from a radial seam or lower lateral band. Should a damaged area be closer than 1 inch to
the cited areas, a miscellaneous patch will be made as detailed in paragraph (c). There are two methods which
may be used to apply a basic patch and the procedures for performing each method are outlined in paragraphs
1 and 2 as follows:
NOTE
A basic patch applied to the parachute canopy by sewing will be square or
rectangular in shape. A parachute canopy basic patch constructed from
adhesive nylon parachute mending cloth may be shaped, rectangular or
triangular as required.

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 in figure 2-107.) Apply a sewn patch as follows:
a
Place the reparable item 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.
b
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 warp or
filling of the material.
c
Cut the damaged area fabric along the lines made in k, above. Further cut the fabric
diagonally at each comer to allow a 1/2-inch foldback in the raw edges.
d
Make a 1/2-inch foldback on each raw edge. Pin and baste each foldback to complete the
prepared hole. Basting will be performed using the procedures in paragraph 2-19a.
e
Using the same type material as in original construction, mark and cut a patch 2 1/2-inches
wider and longer than the inside measurements of the prepared hole.
f
Center the patch material over the prepared hole and insure the warp or filling of each patch
material matches the warp or filling of the fabric being patched. Pin the patch material in
position.
g
Make a 1/2 -inch fold under on each edge of the patch material and baste the patch to the
prepared area. Basting will be performed using the procedures in paragraph 2-19a.
h
Remove the pushpins securing the canopy to the repair table and secure the patch by
stitching, using the applicable details in figure 2-107 and paragraph 2-19b. Make the first row
of stitching completely around the patch. Turn the canopy over and make a second row of
stitching around the prepared hole. Stitching will be performed in accordance with paragraph
2-19b.
