Supersedure : None



### ATA 53 Fuselage –Fuselage Internal Structure at Frame 39.1 - Inspection

Manufacturer(s): Airbus (formerly Airbus Industrie)

Applicability: Airbus A330 aeroplanes, model -342, manufacturer serial numbers (MSN) 0012 and 0017.
Reason: Airworthiness Limitation Item (ALI) task 533105-01-02 is applicable to aeroplanes on which Airbus modification 40391 has not been embodied in production. The requirements associated to this task are applicable to aeroplanes on which Modification Proposal (MP-S10437) has not been embodied. Following a query from an operator, investigations revealed that some MSN, for which Airbus modification 40391 was indicated as fully embodied inside the Aircraft Inspection Report (AIR), did not have Modification Proposal (MP-S10437) which is part of this modification embodied in production. As a result, ALI task 533105-01-02 has not been performed on the MSN listed in the applicability section of this AD, which constitutes an unsafe condition. For the reasons described above, this AD requires repetitive special detailed inspections corresponding to ALI task 533105-01-02 and the accomplishment of the associated corrective actions.EASA AD No.: 2010-0173
