EASA AIRWORTHINESS DIRECTIVE

AD No.: 2012-0182

Date: 11 September 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 

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 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].

Type Approval Holder’s Name :

AIRBUS

Type/Model designation(s) :

A330 aeroplanes

TCDS Number : EASA.A.004

Foreign AD : Not applicable

Supersedure : None

ATA 92 Electric and Electronic Common Installation – Harness 5877VB in 

Section 19.1 – Replacement

Manufacturer(s): Airbus (formerly Airbus Industrie)

Applicability: Airbus A330-201, A330-202, A330-203, A330-223, A330-243, A330-223F,

A330-243F, A330-301, A330-302, A330-303, A330-321, A330-322, A330-323, 

A330-341, A330-342 and A330-343 aeroplanes, manufacturer serial numbers:

1070, 1127, 1133, 1135, 1137, 1138, 1141, 1143, 1145, 1146, 1147, 1149, 

1150, 1151, 1153, 1155, 1156, 1157, 1159, 1160, 1161, 1165, 1167, 1168, 

1169, 1171, 1172, 1173, 1174, 1177, 1178, 1181, 1183, 1184, 1186, 1187, 

1188, 1189, 1191, 1195, 1196 and 1202 inclusive.

Reason: On a production aeroplane, it has been discovered that wires in harness 

5877VB, installed in the Tail Cone (Section 19.1) and connected to the 

Auxiliary Power Unit starter, have a section smaller than required by design.

Section 19 is a flammable fluid leakage zone, adjacent to a fuel tank (trim tank) 

and is open with Section 19.1. The results of the investigation show that this 

issue is a manufacturing quality issue. Airbus identified a list of other 

aeroplanes that are affected.

This condition, if not corrected, could damage the wiring which may create an 

ignition source in an area that may contain fuel vapours, possibly resulting in 

an uncontrolled fire and subsequent loss of the aeroplane.

To address this potential unsafe condition, Airbus developed Service Bulletin 

(SB) A330-92-3116 for aeroplanes in service.

For the reasons described above, this AD requires the replacement of the 

affected wiring harness.
