EASA AIRWORTHINESS DIRECTIVE 

AD No.: 2011-0085 

[Correction: 31 May 2011] 

Date: 12 May 2011 

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) : 

A310 and A300-600 aeroplanes 

TCDS Number : France No 145 

Foreign AD : Not Applicable 

Supersedure : None 

ATA 52 Doors - Forward Cargo Door High Pressure Pipe - Replacement 

Manufacturer(s): AIRBUS (formerly AIRBUS INDUSTRIE). 

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

manufacturer serial numbers (MSN). 

Reason: An A300-600 operator has reported a hydraulic leak at the forward cargo 

door area. After further investigation, the forward cargo door selector valve 

pipe Part Number (P/N) A5231006100300, located in the avionics bay 

opposite to Line Replaceable Unit (LRU) racking, was found cracked. 

This condition, if not detected and corrected, can impact the 90 VU 

avionics LRU, which could result in multiple computer failures, affecting 

flight safety. 

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

aluminium pipe P/N A5231006100300 with a stainless steel pipe P/N 

A5231007000600. 

This AD has been corrected to make clear that the use of Airbus SB A310-

52-2067 and Airbus SB A300-52-6065 at original issue is acceptable to 

comply with paragraph (1) of this AD, unless, inadvertently, the high pressure 

pipe P/N A5231007000600 has been replaced in service, after original issue 

of the SB’s accomplishment, with P/N A5231006100300. 

Effective Date: 26 May 2011

Required Action(s) 

and Compliance 

Time(s): 

Required as indicated, unless accomplished previously: 

(1) Within 30 months or 6 000 flight hours, whichever occurs first after the 

effective date of this AD, replace the aluminium high pressure pipe P/N 

A5231006100300 with a new one, made of Corrosion Resistant 

Stainless Steel (CRES) P/N A5231007000600, in accordance with the 

instructions of Airbus Service Bulletin (SB) A310-52-2067 or SB A300-

52-6065, as applicable to the aeroplane model. 

(2) Aeroplanes that incorporated Airbus Mod 12464 in production have 

been delivered with the new P/N A5231007000600 installed and are 

therefore compliant with the requirements of paragraph (1) of this AD, 

unless the high pressure pipe has been replaced in service after delivery 

of the aeroplane. 

(3) After modification of an aeroplane, as required by paragraph (1) of this 

AD, do not install any aluminium high pressure pipe P/N A5231006100300 

on that aeroplane.
