2. Normal gore section replacement. Gore sections are normally replaced as follows:
a. Remove the damaged section by cutting the section material at a point ½-inch in from the inside edge
of each adjacent seam or lateral band.
b. Cut the remaining fabric diagonally at each corner to allow the raw edges to be folded back.
c. Fold each raw edge back by ½-inch and pin and baste each folded edge to complete area
preparation. Basting will be performed according to the basting and temporary tacking procedures in
WP 0040 00, SEWING PROCEDURES.
d. Position a piece of serviceable parachute cloth, equal to the material used in original gore section
construction, over the prepared area.
e. Cut the cloth piece to a size that will cover the entire prepared area. Allow as many salvaged edges
of the cloth piece to remain as possible. Also allow at least 3-inches of extra fabric to remain on each
Fold under each salvaged edge of the cloth piece to a width equal to the width of adjacent seams and
align the cloth folded edges with the outside edges of adjacent seams or bands. Secure the seams
or bands with pushpins.
g. Fold the raw edges of the cloth pieces as follows:
Fold under the raw edges located adjacent to a lateral band and align the folded edges with the
outside edges of the lateral band. Secure the aligned edges to the applicable lateral band with
Fold under the raw edges located along radial seams that have four rows of stitching and align
the folded edges with the center of the radial seams. Secure the folded edges to the radial
seams with pushpins.
Secure the situated replacement section cloth to the canopy material by basting along each of
the folded edges. Basting will be made according to the basting and temporary tacking
procedures in WP 0040 00, SEWING PROCEDURES.
Remove the pushpins from the edges of the replacement section and secure the section
material to the canopy inside by stitching, according to the details in the illustration below. Use
the stitching procedures in WP 0040 00, SEWING PROCEDURES, with size E nylon thread,
and 7 to 11 stitches per inch.
Turn the canopy right side out and trim the raw edges of the section material to a point ½-inch
from the stitching made in step (4), above.
On the canopy outside, stitch complete around the prepared area using the stitching criteria in
step (4), above.
Reposition the item(s) removed or laid aside in the INSPECTION procedure, above, in the
original location(s) and reattach each item to the canopy by restitching according to original
construction details and WP 0040 00, SEWING PROCEDURES. Use size E nylon thread, and
7 to 11 stitches per inch.
Stencil informational data or other markings on the replacement section using the procedures in
WP 0042 00, MARKING AND RESTENCILLING.
