| This Airworthiness Directive becomes effective on 7 June 2007. |
| Background: | This AD is in response to a manufacturing non-conformity found on one batch of servo-control cap P/N 800137. A defective servo-control may not stop the rotation of the distributor sleeve which could cause untimely movements of the servo-controls which are used on the main and anti-torque rotors. This can lead to loss of control of the helicopter. |
