Unsafe Condition
An incorrectly machined body on the cable assembly could prevent the barrel assembly from fully engaging in the body cavity, leading to disengagement of the cable from the barrel, failure of the tail rotor pitch control, and subsequent loss of control of the helicopter.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Within 25 hours time in service (TIS), inspect each cable assembly for a false cut on the body of the barrel assembly. If a false cut is found, inspect the cable assembly daily for separation of the barrel assembly from the body. If separation is detected, replace the cable assembly before further flight. Within 50 hours TIS, replace the cable assembly with an airworthy one that does not have a false cut in the body.
