(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 paragraph (3). There are three methods
which may be used to apply a basic patch and the procedures for performing each method are outlined in
paragraphs (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 (The sewn patch is shown in figure 2-75.)
Apply a sewn patch as follows:
1 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.
2 Using an authorized marking aid of contrasting color, mark a square or rectangle around the area to
be patched.
3 Cut the damaged area fabric along the lines made in 2 above. Further cut the fabric diagonally at
each corner to allow a 112 inch foldback in the raw edges.
4 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 2-17a.
5 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.
