9-174. Reach forward over the jumper’s shoulders and grasp a riser assembly in each hand just above the No. 1 (large) riser release rings. Since these are like items of equipment, either riser assembly can be inspected first. However, for this talk through begin the inspection with the left riser assembly. Give the left riser assembly a sharp tug to the rear. Open the left hand to form an “L.” Apply upward pressure with the left thumb and trace the riser assembly rearward to where it disappears into the main pack tray, insuring it is not twisted, cut, or frayed. Leave the left hand in place and with the right hand, conduct the same inspection on the right riser assembly. Ensure an Army Parachute Log Record is present in either riser assembly.9-175. An overall inspection of the pack tray must be conducted to ensure the pack tray is free of grease, oil, dirt, mud, or tears. Place both hands, fingers and thumbs extended and joined, palms facing the pack tray, on the top left corner of the pack tray. The left hand is the control hand and the right hand is the working hand. With the head and eyes six-to-eight inches away from the working hand, trace across the top pack closing flap, down the right pack closing flap, and across the bottom pack closing flap. Turn the working hand over so the pinky finger leads the way and trace up the left pack closing flap until skin-to-skin contact is made with the control hand. Raise the control hand up out of the way and trace where the control hand had been. With both hands, fingers and thumbs extended and joined, palms facing the jumpmaster, issue the command, “ARCH YOUR BACK.”
