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. However, if the cited time limitations can
be met, then immediately upon recover, 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 recover, 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.
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
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) 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 Maintenance Allocation Chart (MAC) in WP 0044 00.
7. Record any repair, immersion, and rinsing in the parachute log record as shown in WP 0003 00.
