Parachute mending cloth is not authorized on the T-11R canopy. Use no more than two mending
cloth patches on a canopy section. Limit the size of the finished patch to 10-inches. Round the
corners of the patches to 1-inch radius. Use size E nylon thread, and sew a row of 7 to 11
stitches per inch, 1/16-inch in from the outer edge of the patch. Table 3 prescribes sizes of

2. 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 step 3. There are three
methods that may be used to apply a basic patch; the procedures for performing each method are
outlined in steps a. and b., 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.
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 deployment bag may be patched on either the inside or the outside.
