We are adopting a new airworthiness directive (AD) for certain Airbus Model A318-112 and -121 airplanes; Model A319-111, -112, -115, - 132, and -133 airplanes; Model A320-214, -232, and -233 airplanes; and Model A321-211, -212, -213, and -231 airplanes. This AD was prompted by reports that some nuts installed on the wing, including on primary structural elements, were found cracked. This AD requires inspecting to determine if certain nuts are installed or cracked, and replacing the affected nuts if necessary. We are issuing this AD to detect and correct missing and cracked nuts, which could result in the structural integrity of the airplane wings being impaired.
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 the compliance times specified in paragraph (g)(1) or (g)(2) of this AD, whichever occurs later: Do a detailed inspection of the fuel tank areas of the wings to determine if nuts with part number (P/N) ASNA2531-4 are installed or cracked, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A320-57-1153, Revision 02, including Appendices 01, 02, and 03, dated April 6, 2012. Before further flight, replace any missing or cracked nut with P/N ASNA2531-4 with a new P/N ASNA2531-4 nut, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A320-57-1153, Revision 02, including Appendices 01, 02, and 03, dated April 6, 2012.
(1) Within 6 years after the first flight of the airplane.
(2) Within 6 years after the most recent scheduled fuel tank inspection, or within 6 months after the effective date of this AD, whichever occurs later.
Submit a report of the findings of the inspection required by paragraph (h) of this AD to Airbus, at the applicable time specified in paragraph (h)(1) or (h)(2) of this AD. Submit the report using “Appendix 01—Inspection Report,” of Airbus Mandatory Service Bulletin A320-57-1153, Revision 02, dated April 6, 2012.
(1) If the inspection was done on or after the effective date of this AD: Submit the report within 90 days after the inspection.
(2) If the inspection was done before the effective date of this AD: Submit the report within 90 days after the effective date of this AD.
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.
