3. Fold the canopy back towards the top of the container
and spread the canopy sideways to fill out the width of the
container. [Figure 5-56] Make two folds between the
lower edge of the diaper and the lower end of the closing
loop. [Figure 5-57]

4. Lay the remainder of the canopy and apex across the
middle of the container and fold in an appropriate manner
to fill the empty area of the container on the pack tray
stiffener below the diaper. [Figure 5-58]
CLOSING THE CONTAINER
1. Close the bottom flap of the container first, threading
the pull-up cord through the grommet at the upper end of
the bottom flap. Place the canopy protector flaps into
position as shown in figure 5-59.
2. Close the top flap, being sure to push the canopy and
diaper into the corners of the container while closing.
Thread the upper pull-up cord through the upper grommet
on the top flap.

3. Thread the lower pull-up cord through the lower grommet
on the top flap making sure the canopy protector flaps
are in position. [Figure 5-60] Pull the lower pull-up cord
through both grommets until the closing loop appears and
install a temporary pin.
4. Pull the upper pull-up cord through the grommet until
the upper closing loop appears and install a temporary
pin. [Figure 5-61]
5. Compress the pilot chute between the rubber bumpers
and make sure the pilot chute canopy fabric is tucked
into the coils of the spring. Thread the pull-up cords
through the grommets in the grommet strap. Removing
one temporary pin at a time, pull up the closing loops
and secure the pilot chute in place with two temporary
pins. [Figure 5-62] Close the Velcro® on the top and
bottom flaps.
6. Close the right side flap. Close the left side flap and
install the ripcord pins. [Figure 5-63]
7. Seal the last pin according to the manufacturer’s
instructions or in an approved manner.
RIPCORD PULL FORCE
The correct packing is the most important aspect of
repacking a parachute, but the cosmetic appearance of the
container is important as well. This is true both for a pilot
emergency and a sport piggyback system. Pilots want
their parachute as snug and as flat as possible to keep the Figure 5-60. Closing bottom flap.

Take a length of seal thread approximately 20 inches
long. Fold in half and make two lark’s head knots around
the ripcord cable adjacent to the shank of the ripcord pin.
[Figure 5-65] Pass one end of the thread through the seal
and then under the pin on the opposite side of the locking
loop or cone. [Figure 5-66] Bring the end back through
the second hole in the seal and tie a knot with the other
end of the thread. [Figure 5-67] Leave enough slack in
the thread to allow for movement of the pin without
parachute comfortable when in use. Skydivers want theirs
as snug and streamlined as possible so it stays closed during
free fall. The key to these requirements is to make sure
the pilot chute is held down securely. To do that, the closing
loop needs to be as short as the rigger can make it and
still meet the requirements for the maximum pull force.
Under the TSO system, the maximum allowable pull
force for the ripcord is 22 pounds. Most riggers develop a
feel for the closing of the container and what the resultant
force will be. However, new riggers need to check their
packing technique to measure the pull force, which is
done without a seal or thread.
Start by having someone put on the parachute to replicate
the real shape and conformity of the parachute system. To
pull the ripcord while the parachute is lying on the table is
not realistic. The rigger then takes the ripcord handle
from the pocket and attaches a calibrated scale to it.
[Figure 5-64] Ideally, a recording scale should be used to
register the maximum force during the pull. Next, the rigger
needs to pull the ripcord in a smooth, quick motion,
duplicating the motion of the user and the test requirements
of the TSO. Take note of the force required to pull
the ripcord pin(s) clear of the locking loop(s) and activate
the system. If the force is less than 22 pounds, the rigger
can then re-close the container and seal the ripcord. If the
force is over 22 pounds, the rigger must make whatever
