a. General. A canopy line is a length of nylon cord which extends from a point of attachment on a
connector link assembly on one side of the canopy, up through a canopy radial seam channel, across the
canopy vent, and down through a canopy radial seam to a connector link assembly on the opposite side of the
canopy. As a result of the routing, a canopy line length is divided into segments which are referred to as
suspension line, radial line, and vent line. The procedures that follow include the repair and replacement of
individual segments of the canopy line and the entire canopy line.
b. Repair.
(1) Restitching. Stitch and restitch with thread, nylon, size E, that is contrasting in color to the fabric
being stitched or original thread being restitched. If contrasting color thread is not available, thread
of matching color may be used, providing all other specifications are met. Straight stitching and
restitching should be locked by at least two inches at each end of the stitch row when possible. Zig-
zag restitching should extend at least two inches at each end of a stitch row when possible. Zig-zag
restitching should extend at least 1/4 inch into undamaged stitching at each end, when possible.
Restitch directly over the original stitching and follow the original stitch pattern as closely as
possible.
CAUTION
The radial line portion of a canopy line will not be spliced. Whenever a
canopy line is to be spliced, the splice will be located either above the upper
lateral band or below the lower lateral band.
(2) Splicing a type IV coreless nylon cord suspension line. A suspension line made from type IV coreless
nylon cord will be spliced as follows:
(a) Cut and remove the damaged portion of the line.
