EASA AIRWORTHINESS DIRECTIVE

AD No.: 2014-0034

Date: 05 February 2014

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 21.A.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):

A300-600, A300-600ST and A310 aeroplanes

TCDS Numbers: France No. 145 and EASA.A.014

Foreign AD: Not applicable

Supersedure: None

ATA 24 Electrical Power – Wing Electrical Installation – Modification

Manufacturer(s): Airbus (formerly Airbus Industrie)

Applicability: Airbus A300-600, A300-600ST and A310 aeroplanes, all certified models,

all manufacturer serial numbers.

Reason: Following publication of FAA SFAR 88 (Special Federal Aviation Regulation 

88), EASA issued AD 2006-0076 requiring inspection and corrective action to 

improve the explosion risk protection system for the left hand (LH) and right 

hand (RH) wings on A300, A300-600, A300-600ST and A310 aeroplanes.

For A300-600, A300-600ST and A310 aeroplanes, the required detailed visual 

inspections of electrical bundles located in the leading and trailing edges of the 

RH and LH wings and a review of the wing electrical installation on the final 

assembly line have shown that the wing electrical installation does not comply 

with the minimum distance inspection criteria to the surrounding structure in a 

few wing locations.

This condition, if not detected and corrected, could lead to damage on the 

electrical harnesses and on the surrounding structure.

To address this unsafe condition, Airbus developed an improvement of the wing 

electrical installation to prevent possible chafing and subsequent damage to the 

electrical harnesses and surrounding structure.

For the reasons described above, this AD requires installation of new bracket 

assemblies to ensure the clearance between the wiring and the structure, and 

installation of protective split sleeves as mechanical protection to the electrical 

harnesses.
