The FAA is adopting a new airworthiness directive (AD) for certain Airbus airplane models identified above. This AD requires inspecting to determine if a certain actuator is installed in the pilot's or co-pilot's seat, and doing applicable corrective actions. For certain actuators, the AD also requires replacing rotors on both vertical and horizontal movements with new rotors, and replacing the clutch cap with a new cap. This AD results from a report of heavy wear at the driving gear of the rotor shaft end of the electrical driven motor on certain actuators of the pilot's and co-pilot's seats. We are issuing this AD to prevent uncommanded movement of the pilot's or co- pilot's seat during takeoff or landing, which could result in interference with the operation of the airplane and consequent temporary loss of airplane control.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 56 months after the effective date of this AD, inspect to determine if an actuator identified in Table 2 of this AD is installed in the pilot's or co-pilot's seat, in accordance with Part 1, Paragraph D., “DESCRIPTION,” of Sogerma-Services Service Bulletin TAAI1-25-617, dated February 1, 2005. If any actuator identified in Table 2 of this AD is found installed, within 56 months after the effective date of this AD, do the applicable corrective actions in accordance with Paragraph D., “DESCRIPTION,” of the service bulletin.

Note 1: Sogerma-Services Service Information Letter SIL-TAAI1-25-059, dated February 8, 2005, and Airbus Operator Information Telex SE 999.0040/05/FB, dated May 27, 2005, are additional sources of service information for inspecting the seats.
For Messier-Bugatti actuators identified in Table 2 of this AD: Concurrently with the applicable corrective action required by paragraph (f) of this AD, replace the rotors on both vertical and horizontal movements with new rotors, and replace the clutch cap with a new cap, in accordance with Messier-Bugatti Service Bulletin 4136290004-25-05 or 4136290005-25-02, both dated April 2005, as applicable.
Although Sogerma-Services Service Bulletin TAAI1-25-617, dated February 1, 2005, specifies sending certain information to the manufacturer, this AD does not require that action.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
