j.
Pass the loose end of the replacement vent line through the canopy bridle loop and position the end
of the applicable radial seam on the opposite side of the canopy using the procedures in steps h.
and i., above.
k.
Cut two 6-inch lengths of 9/16-inch wide, type I nylon webbing and wax each webbing end ¼-inch.
l.
Place a 6-inch long webbing lengthwise on the inside of each affected radial seam with the upper
end of each webbing length aligned with the upper edge of the upper lateral band.
m. Ensure each webbing length is centered on the respective radial line and positioned vent line end.
n.
Secure each webbing length with temporary tacking or pushpins.
o.
Working on the canopy outside, secure each positioned end of the replacement vent line to the
applicable radial seam and 6-inch webbing length by stitching a 3/16-inch wide row of double-throw
zig-zag stitching from a point ¼-inch above the upper lateral band to the lower edge of the applicable
vent line end. Stitching will be made using a medium-duty zig-zag sewing machine, size E nylon
thread, and 7 to 11 stitches per inch.
p.
Beginning 6-inches below the upper edge of the upper lateral band, secure each radial line upper
end to the radial seam and 6-inch webbing length by stitching a 6-inch long row of 3/16-inch wide
double-throw zig-zag stitching to the upper edge. Stitching will be made using the procedures
outlined in the REMOVING THE RADIAL LINE paragraph and steps 2t. and 2hh., above.
q.
Remove temporary tacking or pushpins installed in steps c., i., j., and n., above.
r.
Reinstall the upper radial line reinforcement tape removed in step n., above, by restitching according
to original construction details and WP 0045 00, RADIAL LINE REINFORCEMENT TAPE. Stitching
will be made using a medium-duty sewing machine, size E nylon thread, and 7 to 11 stitches per

4. Replacing a Canopy Line. Replace an unserviceable canopy line by fabricating as follows:
a.
Cut and remove all stitching that holds canopy line to canopy.
b.
Remove other items as required, allowing entire line to move freely across lateral bands, through V-
tabs, and within radial seams.
c.
Do not remove V-tabs unless they are damaged.
d.
Cut off damaged line (hereafter referred to as old line) 24-inches below skirt on each side of canopy.
e.
Select a spool of type III nylon cord (hereafter referred to as new line) and wax end of new line.
f.
Insert waxed end of new line into sheath of old line at least 1-inch, and whipstitch, or otherwise
temporarily secure ends together (refer to illustration below).
g.
Grasp cut end of old line at opposite side of canopy skirt and pull old line, working line through V-
tabs and channels and across vent, until end of new line extends approximately 10-inches beyond
link assembly.
