Abstract: An assembly for use with an aerodynamic decelerator for an aerial vehicle, such as a parachute, the assembly having a lead line with a first end and a second end, with the first end structured for attachment to the aerial vehicle, and an energy absorbing assembly having a first end attached to the second end of the shock cord and a second end structured for attachment to the parachute, the energy absorbing assembly in one implementation including an elongate flexible filament having first and second ends attached, the first end attached to the lead line and the second end attached to a decelerator. The first and second ends are attached to each other with rip-stitching, the first and second ends structured to break apart from each other in response to a load exerted by deployment of the parachute.
