TM 10-1670-293-23&P 0011 00 Change 1 0011 00-2 NOTE Once the USL and USL extension has been used in a parachute deployment from an aircraft, the webbing while under tension will stretch, therefore never returning to its original manufactured dimension. That original manufactured dimension is what determines the static line length serviceability at the in-service inspection. NOTE For the USL, when laying out the static line to form the girth hitch, ensure the green ID marking thread of the webbing is on the top. 1. Attaching the USL to the deployment bag. a. Position the deployment bag with the stow loops facing up and pass the 6-inch buffer loop of the USL clockwise, halfway through the deployment bag reinforcement webbing. b. Pass the 3½-inch loop end of the USL through the 6-inch buffer loop, counterclockwise, until a taut girth-hitch is formed.
