Unsafe Condition

Movement of the plain journal bearings to the outside of the main rotor swashplate sliding sleeve. This could limit movement of the collective and result in subsequent loss of control of the helicopter.

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

Required Actions

Visually inspect the position of the upper plain journal bearing to ensure it is flush with the sliding sleeve. Visually inspect the lower plain journal bearing to ensure it is recessed 2 millimeters from the sliding sleeve. If either bearing is not correctly positioned, replace the swashplate assembly with an airworthy one before further flight. Replacing the swashplate assembly with a later design (P/N L623M2005103) constitutes a terminating action.
