Unsafe Condition

occurrences were reported of cables found worn out; the damage consisted of reduction of the cable diameter near the swaged terminal. This condition, if not detected and corrected, could lead to reduction of the cable strength, possibly resulting in an in-flight loss of the hoist load, injury to persons, or damage to and reduced control of the helicopter.

AI-generated summary from the source AD text. Verify against the official source before acting.

Required Actions

inspect the cable near the swaged terminal for cable diameter restriction, the hook assembly stowage force, and the hook assembly stowage at the up limit. If the cable is not compliant due to cable diameter restriction and the results of the hook assembly stowage force inspection, remove the cable from service or replace the cable with an airworthy part before further hoist operation. Follow certain reinstallation steps and report certain information.
