### ATA 56 Windows – Fixed Windows / Windshield Heating Connectors – Inspection / Replacement Manufacturer(s): Airbus (Formerly Airbus Industrie) Applicability: Airbus A330 - 201, A330 - 202, A330 - 203, A330 - 223, A330 - 223F, A330 - 243, A330 - 243F, A330 - 301, A330 - 302, A330 - 303, A330 - 321, A330 - 322, A330 - 323, A330 - 341, A330 - 342 and A330 - 343 aeroplanes, all manufacturer serial numbers (MSN)

. Airbus A340 - 211, A340 - 212, A340 - 213, A340 - 311, A340 - 312, A340 - 313, A340 - 541, A340 - 542, A340 - 642 and A340 - 643 aeroplanes, all MSN

. Reason: Several operators reported cases of burning smell and/or smoke in the cockpit during cruise phase leading in some cases to diversion. Findings show ed that the cause of these events is the burning of the Saint - Gobain Sully (SGS) windshield connector terminal block. This condition, if not corrected, could significantly increase the flight crew workload which would, under some flight phases and/or circumstances constitute an unsafe condition. To address this unsafe condition, Airbus published 3 different Service Bulletins (SB) and EASA issued AD 2011 - 0242 (later corrected) which require d the identification of the installed windshields and replacement of the affected part. Since issuance of that AD, a new occu r rence in service led Airbus to iden tify a new batch of affected parts

. For the reasons described above, t his AD retains the requirements of EASA AD 2011 - 0242, which is superseded, and requires identification and replacement of the additionally identified windshield s .EASA AD No.: 20 13 - 0 256
