TM 10-1670-269-23&P    0011 00 0011 00-1 UNITE MAINTENANCE 24-FOOT DIAMETER TROOP CHEST RESERVE (T-10R) PARACHUTE AND THE MIRPS SALT-WATER CONTAMINATION TEST THIS SECTION COVERS: Inspection INITIAL SETUP: Equipment Condition Layout on packing surface or other suitable area Personnel Required 92R (10) Parachute Rigger INSPECTION Look for a white crystalline residue.  If evidence of salt-water/fresh water contamination is found, refer to the procedures detailed below: Rinsing Parachute Assembly Immersed in Salt-Water.  If the parachute, or any of its components, has been immersed in salt-water in excess of 24-hours it will be condemned.  Additionally, if the parachute, or any of its components, has been immersed in salt-water for a period less than 24-hours, but cannot be rinsed within 48-hours after recovery, it will also be condemned, unless the following actions are performed.  Upon removal from the salt-water, the parachute is placed in a single heavy-duty plastic trash bag, the top of the bag secured closed and kept in a wet state until a rinse can be performed following normal rinse procedures.  The bag must be doubled when outside temperatures exceed 85 degrees F.   The bags must be inspected after transport and storage to insure the bag did not get torn and the assembly was allowed to dry.  Parachutes recovered using this method must be rinsed NLT than 7-days after the salt-water immersion or be condemned.  However, if the cited time limitations can be met, then immediately upon recovery, suspend or elevate the parachute assembly in a shaded area and allow it to drain for at least 5-minutes.  Do not attempt to wring the fabric or the suspension lines.  Within 48-hours after recovery, under the supervision of a qualified parachute rigger (92R), rinse the recovered parachute assembly as follows: 1.    Place the parachute assembly in a large watertight container filled with a suitable amount of fresh, clean water to cover the assembly. NOTE If the salt-water-soaked parachute assembly is too large to be placed into a rinsing container, then the rinsing process will be affected by applying fresh, clean water to the assembly using a hose. 2.    Agitate the container contents by hand for 5-minutes. 3.    Remove the parachute assembly from the container and suspend or elevate it in a shaded area, allowing a 5-minute drainage period.  Do not attempt to wring the fabric or the suspension lines. 4.    Repeat the procedures in steps 1. through 3., detailed above, twice, using fresh, clean water for each rinse. 5.    After the third rinse, allow the parachute assembly to drain thoroughly.  Upon completion of draining, dry the assembly in accordance with the Drying Fabric Items procedures detailed below. 6.    When dried, perform a technical/rigger-type inspection of the parachute assembly.  Corroded metal components, or corrosion-stained fabrics or suspension lines, will be either repaired or replaced as prescribed by the MAC in WP 0044 00.
