SLACK CHECKER INSPECTION (AR2 Reserve Mounted ONLY)
After every jump and /or repack of the reserve parachute, the parachute rigger is to inspect cable
extension length with the slack checker as follows:
1. The MC-4 must have an AR2 and power cable assembly correctly installed and routed to the reserve
parachute. Ensure that the position of the AR2 in the pocket is the same as when worn by a jumper.
2. Open top flap of parachute to expose the reserve ripcord pins.
3. Slide the metal head of the slack checker under the power cable from the right side so the cable slips
into the curved groove between the metal head and plastic handle. Engage the two contact points on
the hooked end of the slack checker with the mouth of the end fitting of the power cable housing. The
slack checker should be held flat against the parachute pack. The two contact points must be
engaged at all times to ensure proper inspection. (Refer to the illustration below).
4. Grasp the slack checker with the right hand, palm down, and with the thumb pressed into the curved
recess. Grasp the swaged section of the ripcord pin with left hand. Simultaneously rotate the slack
checker and ripcord pin in the directions shown by the arrows. Hold the ripcord pin with the left hand
in a fixed position when it becomes horizontally aligned. (Refer to the illustration below.)
