Airbus Model A330-200 and -300, and A340-200 and -300 Series Airplanes
This AD applies to Airbus Model A330-201, 202, -203, -223, and -243; A330-301, -302, -303, -321, -322, -323, -341, -342, and -343; A340-211, -212, and -213; and A340-311, -312, and -313 airplanes, certificated in any category; except airplanes on which Airbus Modification 50138 was done during production.
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A330-200 and -300, and A340-200 and -300 series airplanes. This AD requires modifying certain rotary actuator assemblies for the leading edge slat. This AD results from a leak found at the seal of the torque limiter output shaft of the Type A rotary actuator of leading edge slat No. 1. We are issuing this AD to prevent a decrease in the torque limiter function, which could result in degradation and damage to the attachment bolts of the leading edge slat, loss of the slat, and consequent reduced control of the airplane.
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 38 months after the effective date of this AD: Modify any Type A rotary actuator assembly for the leading edge slat having part number (P/N) 954A0000-01 or 954A0000-02, or P/N 954B0000-01, as applicable, by doing all the applicable actions in accordance with the Accomplishment Instructions of Airbus Service Bulletin A330-27-3100, Revision 01, dated May 23, 2005; or A340-27-4106, Revision 01, dated May 23, 2005; as applicable.
(g) Modification of any Type A rotary actuator assembly for the leading edge slat having P/N 954B0000-01, in accordance with Airbus Service Bulletin A330-27-3105 or A340-27-4110, both Revision 02, both dated October 10, 2005; as applicable; is acceptable for compliance with the corresponding modification specified in paragraph (f) of this AD.
Note 1: Airbus Service Bulletins A330-27-3100 and A340-27-4106 refer to Goodrich Actuation Systems Service Bulletin 954-27-M954-07, Revision 2, dated August 9, 2004; and Airbus Service Bulletins A330-27-3105 and A340-27-4110 refer to Goodrich Actuation Systems Service Bulletin 954-27-M954-06, Revision 2, dated May 20, 2004; as additional sources of service information for modifying the rotary actuator assembly for the leading edge slat.
As of the effective date of this AD, no Type A rotary actuator assembly for the leading edge slat having P/N 954A0000-01, -02, or 954B0000-01 may be installed unless the part has been modified in accordance with the actions required by paragraph (f) or (g) of this AD, as applicable.
(i) Modifications done before the effective date of this AD in accordance with Airbus Service Bulletins A330-27-3100, dated October 30, 2002; A330-27-3105, dated October 30, 2002, or Revision 01, dated March 27, 2003; A340-27-4106, dated October 30, 2002; or A340-27-4110, dated October 30, 2002, or Revision 01, dated March 27, 2003; as applicable; are acceptable for compliance with the corresponding requirements of paragraphs (f) and (g) of this AD, as applicable.
