             This Amendment becomes effective on 10 September 2005.
Background:  The Direction Générale de l'Aviation Civile of France has advised that following removal of a tail servo-control for repair, it was reported that a control lever had slipped along the shaft of one of the distributors.  Investigation revealed that the control lever could have totally separated from the distributor shaft, which could result in tail servo-control failure.

             The original issue of this Directive required a one time manual inspection to ensure the integrity of the servo-control assembly.

             This amendment maintains the one time inspections, introduces follow up inspections and torque checks, and includes actions to be performed if tail servo-controls fail those checks detailed in this Directive.

             The original issue of this Directive became effective on 7 January 2005.
