Applicability*9

Model A330-301, -321, -322, -341, and -342 series airplanes on which Airbus Modification 45631 has not been installed; and Model A340-211, -212, -213, -311, -312, and -313 series airplanes [[Page 1911]] on which Airbus Modification 45485 has not been installed; certificated in any category. Note 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been otherwise modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (b) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.

Compliance

Required as indicated, unless accomplished previously. To prevent uncommanded movement of the trimmable horizontal stabilizer (THS), which could result in reduced controllability of the airplane, accomplish the following: (a) Within 500 flight hours after the effective date of this AD, perform an operational test of the THS override mechanism to determine if the override system functions correctly, in accordance with paragraph (a)(1) or (a)(2) of this AD, as applicable. Repeat the operational test thereafter at intervals not to exceed 500 flight hours. (1) For Model A330 series airplanes: Perform the operational test in accordance with Airbus Service Bulletin A330-27-3051, dated February 13, 1997; and, prior to further flight, repair any discrepancy in accordance with this service bulletin. (2) For Model A340 series airplanes: Perform the operational test in accordance with Airbus Service Bulletin A340-27-4058, dated February 13, 1997; and, prior to further flight, repair any discrepancy in accordance with this service bulletin. (b) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, International Branch, ANM-116, FAA, Transport Airplane Directorate. Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, International Branch, ANM-116. Note 2: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the International Branch, ANM-116. (c) Special flight permits may be issued in accordance with sections 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 21.197 and 21.199) to operate the airplane to a location where the requirements of this AD can be accomplished. (d) The actions required by this AD shall be done in accordance with Airbus Service Bulletin A330-27-3051, dated February 13, 1997 (for Model A330 series airplanes); or A340-27-4058, dated February 13, 1997 (for Model A340 series airplanes); as applicable. This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51.
