Attach 15-Foot Modified Universal Static Line (USL) and Universal Static Line (USL) Extension to
the Deployment Bag
Once the 15-foot modified Universal Static Line (USL) and the USL Extension has been
used in a parachute deployment from an aircraft, the webbing, while it is under tension,
will stretch, therefore never returning to its original manufactured dimension. That original
manufactured dimension is what determines the serviceability at the in-service inspection.
When laying out the 15-foot Modified USL or the USL extension to form the girth hitch,
ensure the green ID marking thread of the webbing is on the top.
1. Attaching the 15-foot Modified USL to the deployment bag.
a. Position the deployment bag (figure 14, item 1) with the stow loops (figure 14, item 2) facing up.
Pass the 6-inch buffer loop (figure 14, item 3) of the static line (figure 14, item 4) left to right,
halfway through the deployment bag reinforcement webbing (figure 14, item 5) ensuring that you
go through both plies.

b. Pass the 3-inch loop end (figure 15, item 1) of the static line (figure 15, item 2) through the 6-
inch buffer loop (figure 15, item 3), counterclockwise until a taut girth hitch is formed.
