4. Look at the rear of the riser and with the weight (min 20-lbs) of the parachute rig (minus main
parachute) suspended by the riser to be inspected, grasp the release cable housing by the swaged
terminal end fitting with the small grommet in it and slide the end fitting to one edge (either edge) of
the riser. You must NOT be able to move the fitting (do not use excessive force to move the fitting)
completely off the edge of the riser (as depicted in the right illustration below), thus ensuring the
fabric-locking loop is not too long. The length of the fabric locking loop should range as shown below.
5. Periodic Maintenance Procedures. The three-ring release system is a durable item; however; it
requires periodic maintenance and inspection to ensure proper operation. The 3-ring release will be
carefully inspected and cycled (operated) on a regular basis. The procedures below will be
completed every 120-days. This is especially important if the parachute system has not been used
for 120-days or more (such as during the winter). Immediate inspection is required if the system has
been subjected to abuse such as drug across the ground, a water landing, or exposure to a lot of dust
or sand. Perform inspection as follows:
a. Every 120 days operate the 3-ring release assembly on the ground by removing the cutaway
handle. Extract the release cable completely from the housing and disconnect the risers.
