EASA AIRWORTHINESS DIRECTIVE 

AD No.: 2010-0173 

Date: 17 August 2010 

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 EC 1702/2003, Part 21A.3B. In accordance with EC 2042/2003 Annex I, Part M.A.301, 

the continuing airworthiness of an aircraft shall be ensured by accomplishing any applicable ADs. Consequently, no person 

may operate an aircraft to which an Airworthiness Directive applies, except in accordance with the requirements of that 

Airworthiness Directive unless otherwise specified by the Agency [EC 2042/2003 Annex I, Part M.A.303] or agreed with the 

Authority of the State of Registry [EC 216/2008, Article 14(4) exemption].

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.
