EASA AIRWORTHINESS DIRECTIVE

AD No.: 2013-0165

Date: 25 July 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 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):

A310 aeroplanes

TCDS Number: France n° 145

Foreign AD: Not applicable

Supersedure: None

ATA 29 Hydraulic Power – Electrical Motor Pump Electrical Routing and 

Hydraulic Pipes – Modification

Manufacturer(s): Airbus (Formerly Airbus Industries)

Applicability:

Airbus A310 aeroplanes, all certified models, all manufacturer serial numbers

on which Airbus Modification No 04797 has been embodied in production or

those on which Airbus Service Bulletin (SB) A310-29-2091 has been embodied 

in service.

Reason: An A310 operator reported an electrical arc and a large hydraulic haze in the 

Left Hand (LH) Main Landing Gear (MLG) wheel bay that occurred during 

ground operation.

The analysis of the occurrence revealed that this was likely caused by chafing 

between a hydraulic high pressure hose and electrical wiring of the Green 

Electrical Motor Pump (EMP).

This condition, if not detected and corrected, could result in an undetected and

uncontrolled fire in the LH MLG wheel bay.

For the reason described above, this AD requires modification of the electrical 

routing and installation of reinforced hydraulic pipes.

Effective Date: 08 August 2013
