The crown line assembly includes seven panels with the pilot chute bridle line being secured along the junction of two panels and webbing member secured along other junction lines between panels. Pilot chute bridle attachment loops are connected to the webbing members and pass through a loop on the bridle. Thong-disc attachment loops are also secured to the webbing members and pass through the loops on the crown lines and then engage the thongs on the thong-disc assembly.
