i.
Working at the canopy vent and using a suitable marking aid, mark the original radial line at the
upper edge of the upper lateral band.
j.
Pull 10-inches of the damaged radial line from the upper end of the radial seam and cut the line
length at a point 6-inches below the mark made in i., above.
k.
Pull the original radial line up through the radial seam until the attached replacement line length
extends 2-inches beyond the upper edge of the upper lateral band.
l.
Cut the replacement radial line length even with the upper edge of the upper lateral band.
Temporarily secure the line end to the upper lateral band with tacking or pushpins.
m. Cut a 6-inch length of 9/16-inch wide, type I nylon webbing and wax each end by ¼-inch.
n.
Place the webbing length lengthwise over the original radial seam upper end on the canopy inside
and align the webbing upper end with the upper edge of the lower lateral band.
o.
Secure the webbing length in position using temporary tacking or pushpins.
p.
Place the loose end of the original vent line on the radial seam outside, adjacent to the replacement
radial line.
q.
Align the mark made in step i., above, with the upper edge of the upper lateral band.
r.
Secure the vent line loose end and the upper end of the replacement radial line to the radial seam
using temporary tacking or pushpins.
s.
Working on the outside of the canopy top, secure the 6-inch long webbing seam by making a row of
3/16-inch wide double-throw zig-zag stitching from ¼-inch above the upper lateral band to the end of
the vent line. Stitching will be made using size E nylon thread, 7 to 11 stitches per inch with a
medium-duty zig-zag sewing machine.
t.
Beginning at a point 6-inches below the upper lateral band upper edge, secure the 6-inch long
webbing and the upper end of the replacement radial line by stitching a 6-inch long row of 3/16-inch
wide double-throw zig-zag stitching to the upper edge of the upper lateral band. Stitching will be
made using a medium-duty zig-zag sewing machine and size E nylon thread, 7 to 11 stitches per
inch.
u.
Remove temporary tacking or pushpins installed in steps n. and o., above.
