d. Position the webbing on the damaged area. Use a medium-duty sewing machine and size E,
nylon, thread to stitch. Sew webbing in place with four continuous rows of stitching, 7 to 11
stitches per inch. Overstitch the ends of the webbing 2-inches.
e. Reposition apex/vent lines and sew them in place according to original construction.
3. Damage Extending Into Radial Seam:
a. Cut the stitching of the apex/vent line attached to the damaged radial seam and the stitching of the
two vent lines on each side of the damaged seam. Move the lines to one side.
b. Invert the apex and smooth the canopy around the damaged area.
c. Cut a piece of 1-inch tubular, nylon webbing, long enough to extend 1-inch beyond the outside edge
of the second radial seam, on each side of the damaged area. Sear or dip the ends of the webbing.
