AD 97-22-13 Airworthiness Directives; Airbus Model A320 and A321 Series Airplanes

Models named: A320, A321 series. Read the applicability below — it usually turns on serial or part numbers too.

Model A320 and A321 series airplanes, on which Airbus Modification 24612 or Airbus Service Bulletin A320-31-1080 has not been accomplished; 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 (c) 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.

Required as indicated, unless accomplished previously. To prevent severely reduced controllability of the airplane during approach, accomplish the following: (a) At the applicable time specified in either paragraph (a)(1) or (a)(2) of this AD, revise the Limitations Section of the FAA- approved Airplane Flight Manual (AFM) to include the information specified in Airbus A320/A321 Flight Manual Temporary Revision 9.99.99/20, dated June 14, 1994. Note 2: This may be accomplished by inserting a copy of Airbus A320/A321 Flight Manual Temporary Revision 9.99.99/20, dated June 14, 1994, in the AFM. When this temporary revision has been incorporated in the general revisions of the AFM, the general revisions may be inserted in the AFM, provided the information contained in the general revisions is identical to that specified in Temporary Revision 9.99.99/20. (1) For Model A320 series airplanes: Revise the AFM within 10 days after October 7, 1994 (the effective date of AD 94-20-02, amendment 39-9030). (2) For Model A321 series airplanes: Revise the AFM within 10 days after the effective date of this AD. (b) Within 6 months after the effective date of this AD, install a new, improved flight warning computer (FWC) in accordance with Airbus Service Bulletin A320-31-1080, Revision 01, dated July 12, 1996 or Revision 2, dated October 24, 1996. Prior to further flight after accomplishing this installation, remove the AFM revision required by paragraphs (a) of this AD. (c) 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, Standardization Branch, ANM-113, FAA, Transport Airplane Directorate. Operators shall submit their requests through an appropriate FAA Principal Operations Inspector, who may add comments and then send it to the Manager, Standardization Branch, ANM-113. Note 3: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Standardization Branch, ANM-113. (d) 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. (e) The installation shall be done in accordance with Airbus Service Bulletin A320-31-1080, Revision 01, dated July 12, 1996, or Airbus Service Bulletin A320-31-1080, Revision 02, dated October 24, 1996.
