EASA AIRWORTHINESS DIRECTIVE

AD No.: 2013-0196

Date: 28 August 2013

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 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 AD applies, except in accordance with the requirements of that AD, 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].

Design Approval Holder’s Name:

AIRBUS

Type/Model designation(s):

A330 and A340-200/300 aeroplanes

TCDS Number: EASA.A.004, EASA.A.015

Foreign AD: Not applicable

Supersedure: None

ATA 92 Electric and Electronic Common Installation – Harness at 

Door 3 Area – Modification

Manufacturer(s): Airbus (formerly Airbus Industries)

Applicability: Airbus A330-201, A330-202, A330-203, A330-223, A330-243, 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) on which Airbus 

Modification (Mod) No 48825 is embodied in production, except those on which 

Mod No 52485 or Mod No 40161 or Mod No 201669 are embodied.

Airbus A340-211, A340-212, A340-213, A340-311, A340-312 and A340-313 

aeroplanes, all MSN on which Airbus Mod No 48825D42865 is embodied in 

production, except those on which Mod No 55606 or Mod No 40161 are 

embodied.

Reason: On the production line, electrical harnesses 1523VB and 1524VB have been 

found in contact with hatrack rod at Frame (FR) 53.7 between stringers (STR) 

14 and 15. It was concluded that there is a risk of chaffing between these 

harnesses and the surrounding structure, which could lead to a short circuit on 

two oxygen chemical generator containers in different wiring routes. 

Consequently, the electrical opening of all the containers connected to these 

routes would not be possible, resulting in a malfunction of up to two thirds of the 

affected containers.

This condition, if not corrected, could lead, in case of a sudden 

depressurisation event, to lack of oxygen supply, possibly resulting in injuries to 

aeroplane occupants.

To address this potential unsafe condition, Airbus developed two modifications

of the routing of the affected harnesses.
