    Manufacturer(s):                 Airbus

    Applicability:                   Airbus A380-841, A380-842, and A380-861 aeroplanes, all manufacturer
                                     serial numbers (MSN), except aeroplanes on which Airbus modification
                                     71738 has been embodied in production.

    Reason:                          Reboots of the Acquisition and Flight Data Interface Application (AFDIA)
                                     software of the Centralized Data Acquisition Module (CDAM) have been
                                     reported.
                                     Investigations have revealed that the content of the non-volatile memory had
                                     been corrupted, which causes the unit to reboot continuously.
                                     This condition, if not corrected, could result in a deficiency in systems used
                                     to assist in the enquiry following an accident or serious incident, preventing
                                     them to perform their intended function.
                                     For the reasons described above, this AD requires the installation of the
                                     updated AFDIA software, which ensures correct operation of the CDAM.

    Effective Date:                  01 February 2012

    Required Action(s)               Required as indicated, unless already accomplished:
    and Compliance

                                       AD No.: 2012-0011



                                       Date: 20 January 2012

                                       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

    Manufacturer(s):                Airbus

    Applicability:                  Airbus A380-841, A380-842, and A380-861 Aeroplanes, manufacturer serial
                                    numbers (MSN): 0003, 0005 through 0017 inclusive, 0019 through 0023
                                    inclusive, 0025 through 0030 inclusive, 0033, 0034, 0038, 0040, 0041, 0043,
                                    0045 and 0051.

    Reason:                         During an inspection on an in-production aeroplane, the following non
                                    conformities have been discovered on an APU air intake duct access cover
                                    cut-out:
                                        - Missing epoxy resin around the inserts and at the edge of the air
                                             intake duct wall cut-out, and
                                        - Missing epoxy adhesive at the edges of the air intake duct wall cut-
                                             out.
                                    It was found that these materials have not been applied on a specific group of
                                    aeroplanes due to an incorrect quality process during production. However,
                                    the fire sealant ensures continuing proper fire protection.
                                    In addition, it has been identified that task 49-16-00-210-801-A of the Airbus
                                    A380 Aircraft Maintenance Manual (AMM), titled “General Visual Inspection of
                                    inner surfaces of Air Intake Duct and P-Seal at Housing/Duct Interface”, did
                                    not contain instructions to apply fire sealant compound for the in-service
                                    installation procedure of the APU air intake duct inspection access cover.
                                    The investigation has shown that the in-service accomplishment of this
                                    incorrect AMM task in combination with the absence of epoxy resin and
