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 aircra ft shall be ensured by accomplishing any applicable ADs.

### 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 2011EASA AD No : 2011-0085

EASA Form 110 Page 2/2 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 requir ements 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.
