FIGURE EIGHT TIE
NOTE
When the extraction parachute is used as an “extraction parachute”, the breakcord tie
will be one turn double, type I, ¼-inch cotton webbing. When the extraction parachute
is used as a “drogue parachute,” the breakcord tie will be one turn single, ½-inch
tubular nylon.
1. Figure Eight Tie
a. Cut one 60-inch length of ½-inch tubular nylon webbing and one 12-inch length (doubled) of ticket #8/7
cotton thread.
b. Thread the end of a 60-inch length of ½-inch tubular nylon up through the bottom left and up through the
top left bag-closing loop.
c. Equalize the ends and thread both ends through the cutter knife between the blade and the reinforcing
safety bar.
d. Cross the ½-inch tubular nylon at the cutter knife and thread the bottom running end up through the
bottom right bag-closing loop. Thread the top running end down through the top right bag-losing loop.
e. Draw the figure eight as tight as possible and secure between the right bag-closing loops with a
surgeon’s knot, locking knot and an overhand knot in the running ends. Trim ends to 2-inches.
f. Safety tie the cutter knife by passing the 12-inch length of one turn double ticket #8/7 cotton thread
around the crossed ½-inch tubular nylon and through the holes above the reinforcing safety bar of the
cutter knife. Secure with a surgeon’s knot and locking knot (Figure 1).
