2-17. Repair Procedures (CONT).
(3) Applying a miscellaneous canopy patch. A miscellaneous canopy patch, which may be irregularly
shaped, is used to repair damaged canopy material when the location of the damaged area requires the patch
to extend into or over a seam, reinforcement, or lateral band. Ascertain the type of patch required for the
canopy, using the details In figure 2-77. A canopy gore section that cannot be patched with a basic patch as
outlined in paragraph (2), above, will be patched with a miscellaneous patch. Apply a miscellaneous patch to a
gore section as follows:
NOTE
Adhesive nylon parachute mending cloth will not be used in the construction or
application of a miscellaneous canopy patch.
(a) Place the canopy inside out on a repair table, smooth the fabric around the damaged area,
and secure the damaged gore section to the table with pushpins. Do not pin the damaged
area of the gore section.
(b) As required, cut the applicable stitching to remove or lay aside items which may interfere
with the patching process.
(c) Using an authorized marking aid of contrasting color, mark a rectangle or triangle around the
damaged area. Make the mark 1/2 inch from any adjacent seam, reinforcement, or lateral
band.
(d) Prepare the damaged area hole by cutting along the marks made in (c), above. Also make a
diagonal cut at each corner of the formed hole to permit a foldback of each raw edge.
(e) To complete hole preparation, make a 1/2-inch foldback of each raw edge. Pin and baste
each edge foldback using the procedures in paragraph 2-17a.
(f) Using the same type material as In original canopy construction, mark and cut a patch 2 1/2-
inches wider and longer than the inside measurements of the prepared hole.
(g) Center the patch material over the prepared hole. Pin the patch material in position.
(h) Make a 1/2-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 paragraph 2-17a.
