A patch will not be applied to a damaged area that has been previously patched.
There is no limitation to the number of patches or size of patch to each canopy panel or gore
panel. However, determination should be made as to the most economical method to be
used, i.e., two or more patches versus one large patch or one large patch versus a panel
replacement. A patch applied to a parachute canopy may extend from radial seam to radial
Sewn patches. There are two types of sewn patches authorized, the basic and miscellaneous. A
basic patch is used to repair damaged cloth when the affected area is no closer than 1 inch from a
radial tape, vent reinforcement tape or skirt reinforcement tape. Should a damaged area be closer
than 1 inch to the cited areas, a miscellaneous patch will be made.
Sewn patches on the canopy will be applied to the inside and may be square or
rectangular in shape.
Using an authorized marking aid of contrasting color, mark a square or rectangle around area
to be patched and insure one side of marked square or rectangle is parallel to warp or filling of
Cut damaged area fabric along lines made in 1 above. Further cut fabric diagonally at each
corner to allow a 112 inch foldback in raw edges. Cut stitching and lay aside or remove any
item which will interfere with miscellaneous patch application.
Make 1/2 inch foldback on each raw edge. Pin and baste each foldback to complete
prepared hole. Basting will be performed using procedures in paragraph 2-17a.
Using 3.8 ounce cotton muslin cloth, mark and cut a patch 2-1/2 inches wider and longer than
inside measurements of prepared hole. Insure patch material is marked and cut along warp
or filling of fabric.
Center patch material over prepared hole and insure warp or filling of patch material matches
warp or filling of fabric being patched. Pin patch material in position.
Make 1/2 inch foldunder on each edge of patch material and baste patch to prepared area.
Basting will be performed using procedures in paragraph 2-17a.
Remove pushpins securing item to the repair table and secure patch by stitching, using the
stitching specifics outlined in table 2-3. Make first row of stitching completely around patch.
Invert canopy and make a second row of stitching around prepared hole. Stitching will be
performed in accordance with paragraph 2-17.
