## EASA AIRWORTHINESS DIRECTIVE

AD No

. : 2015 - 0036 R1

Date: 3 1 March 2015

Note: This Airworthiness Directive (AD) is issued by EASA, acting in accordance with Regulation (EC) No 216/2008 on behalf of the European Community, its Member States and of the European third countries that participate in the activities of EASA under Article 66 of that Regulation. This AD is issued in accordance with EU 748/2012, Part 21.A.3B. In accordan ce with EU 1321/2014 Annex I, Part M.A.301, the continuing airworthiness of an aircraft shall be ensured by accomplishing any applicable ADs. Consequently, no person may ope rate an aircraft to which an AD applies, except in accordance with the requirements of that AD, unless otherwise specified by the Agency [EU 1321/2014 Annex I, Part M.A.303] or agreed with the Authority of the State of Registry [EC 216/2008, Article 14(4) exempt ion].

. Reason: During A320 family Extended Service Goal full scale fatigue tests, it was demonstrated that the inspection thresholds defined in the current Structural Repair Manual (SRM) for the A320 family skin repairs are insufficient to detect possible cracks becoming after repairs. The findings are limited to 1.2 mm fuselage skin and cover for all cut

- out external repairs. The internal repairs are not af fected. This condition, if not detected and corrected , could affect the structural integrity of the fuselage at the repaired skin area(s). To address this potential unsafe condition, Airbus issued Alert Operators Transmission (AOT) A53N007

- 14 to provide inspection instructions. For the reasons describe d above, EASA issued AD 2015

- 0036 to require a one - time inspection of the affected areas and, depending on findings, accomplishment of applicable repair instructions

. Since that AD was issued, operator s have questioned the inspection threshold for A318 aeroplanes (not yet in the Airbus AOT) , which is actually identical to th at for A319 aeroplanes. In addition, an error has been detected in paragraph (1), since external doublers may have been installed in the affected area by aEASA AD No.: 2015

. Such doubler installation s are also subject to the inspection requirements of this AD , which is therefore revised to provide clarification s , correcting paragraph (1) and i ntroducing a Note

. Effective Date: Revision 1: 07 April 2015 Original issue: 17 March 2015 Required A ction(s) and Compliance Time(s) : Required as indicated, unless accomplished previously: (1) Within the compliance time defined in Airbus AOT A53N007

- 14 , as applicable (see Note 1) , or within 350 flight cycles after 17 March 2015 [ the effective date of the original issue of this AD ] , whichever occurs later , identify whether any fuselage external skin (doubler) installations have been accomplished on fuselage sections 11, 12, 13, 14, 16 and/or 17 , and, for each of the repai r ed 1.2 mm fuselage skin areas, as applicable, accomp lish an Ultrasonic (US) inspection from external , or a Low Frequency Eddy Current ( LFEC ) inspection from internal , in accordance with the instructions of Airbus AOT A53N007

- 14. A review of aeroplane maintenance records is acceptable to make th e identification of an affected repair , provided those records can be relied upon for the purpose of this requirement. Note 1: For A318 aeroplanes, the applicable inspection threshold (not in the Airbus AOT at original issue ) is identical to that for A319 aeroplanes. (2) As an alternative to the LFEC or US inspection as required by paragraph (1) of this AD, a o ne - time High Frequency Eddy Current (HFEC) inspection in acc ordance with Non

. (3 ) The i nspection as required by paragraph (1) of this AD can be delayed , provid ed that repetitive Detail ed Visual In spection s (DVI), or High Frequency Eddy Current (HFEC) inspections are accomplished within the compliance time s defined in, and in accordance with the instructions of , Airbus AOT A53N007

( 4 ) If, during any US or LFEC inspection as required by paragraph (1 ) of this AD , or during the HFEC inspection as specified in paragraph (2) of this AD, or during any DVI or H FEC inspection as required by paragraph ( 3 ) of this AD, as applicable, any crack is found, before next flight, accomplish an applicable repair in accordance with the instructions of Airbus AOT A53N007
