REPAIR
1. Preparation for Patching. Prepare the radial seam for patching as follows:
a. Place the canopy on a repair table with the damaged side of the radial seam facing up.
b. As required, cut the applicable stitching to remove or lay aside items, which may interfere with the
patching process.
c. Smooth the canopy material surrounding the damaged area and secure the undamaged portion
of the seam to the table with pushpins. Do not pin the damaged area of the seam.
d. Using the same type material as in original canopy construction, bias-cut a rectangular patch 3 ½-
inches wider and 4-inches longer than the damaged area. If one piece of material is not long
enough to achieve the required size, join additional pieces of bias-cut material with ½-inch wide
lapped seams.
NOTE
Patch material for a damaged area that does not exceed 1-inch
need not be bias cut.
2. Patching Radial Seam. There is no limit to the length of a patch made on a canopy radial seam. In
addition, a radial seam may be patched on both the inside and the outside of a canopy, as required.
Patch a damaged radial seam as follows:
a. Fold the patch material in half lengthwise and align the raw edges.
b. Make a ½-inch fold-under on the raw edges of the patch material and baste the fold-under using
the procedures in WP 0014 00.
c. Make a 1-inch fold-under on each end of the patch material and baste each fold-over using the
procedures in WP 0014 00.
