(c) Divide the center of the canopy vent lines into two equal groups and insert 3 inches of the cloth
between the two groups (A, figure 2-58).
(d) Extend the opposite end of the cloth down toward the inside of the vent lines and around both vent
line groups to serve the vent lines (B, figure 2-58).
(e) At a point 1 inch back from each outside edge of the vent line serving cloth, secure each end by
making a tie around the vent lines with a 24-inch length of type I cotton webbing (C, figure 2-58).
Make the tie with 2 turns single and secure the tie with a surgeon's knot and a locking knot. Trim tie
ends to 2 inches.
(2) Attaching center line to canopy vent lines.
(a) Pass one loop of the center line around the center of the vent lines.
(b) Pass the opposite end of the center line through the end loop routed around the vent lines. Draw the
center line length through the loop until a snug girth hitch is formed around the vent lines (figure 2-
59).
(c) S-fold the center lines, and place them as far as possible inside the canopy.
(d) Reconnect the canopy bridle loop to the stationary post.
(3) Applying tension.
(a) Insure that the two risers are attached to the body of a ¾ inch shackle (clevis) and the applicable nut
and screw are installed on the clevis.
(b) Connect the 3/4-inch clevis to a tension device and apply tension.
NOTE
A tension jack, chain hoist, power winch or a vehicle may be used as a tension
device when applying tension to the parachute canopy.
(4) Folding the gores. Fold the canopy gores into two groups of 32 gores each as follows:
(a) At a point 1 feet below the canopy skirt, position a large circulating fan in a manner that will allow the
fan air stream to partially inflate the canopy. Turn fan on.
(b) With the fan operating and rigger number 1 holding the canopy skirt at least shoulder high to allow
the canopy to partially inflate, rigger number 2 will move through the canopy inside to the canopy
vent and pull the center line length back through the canopy to within approximately 6 inches of the
canopy skirt.
