EASA AIRWORTHINESS DIRECTIVE

AD No.: 2015-0028R1

Date: 29 May 2015

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 EU 1321/2014 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 

[EU 1321/2014 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) :

A330 and A340 aeroplanes

TCDS Numbers: EASA.A.004, EASA.A.015

Foreign AD : Not applicable

Revision : This AD revises EASA AD 2015-0028 dated 24 February 2015.

ATA 52 Doors – Potable Water Service Panel Access Door Latching 

Mechanism – Modification

Manufacturer(s): Airbus (Formerly Airbus Industrie)

Applicability: Airbus A330-201, A330-202, A330-203, A330-223, A330-243, A330-301,

A330-302, A330-303, A330-321, A330-322, A330-323, A330-341, A330-342, 

and A330-343 aeroplanes, all Manufacturer Serial Number (MSN), except those 

on which Airbus modification (Mod) 201715, or Airbus Mod 201796, or Airbus 

Mod 201938 has been embodied in production.

Airbus A340-211, A340-212, A340-213, A340-311, A340-312, A340-313,

A340-541, A340-542, A340-642 and A340-643 aeroplanes, all MSN.

Reason: Several cases have been reported in which the potable water service panel 

access door was lost during flight, causing damage to the trimmable horizontal 

stabilizer. The results of subsequent investigations showed that these events 

were due to failure of the latching mechanism of the potable water service panel 

access door.

This condition, if not corrected, could lead to further cases of in-flight loss of the 

potable water service panel access door, possibly resulting in injury to persons 

on ground and/or damage to the aeroplane.

To address this condition, Airbus developed a modification and published 

Service Bulletin (SB) A330-52-3086, SB A340-52-4094 and SB A340-52-5019, 

to provide instructions for in-service accomplishment of that modification.

Consequently, EASA issued AD 2015-0028 to require modification of the 

potable water service panel access door 164AR for A330/A340-200/-300 

aeroplanes or 154BR for A340-500/-600 aeroplanes, which includes installation 

of reinforced hinge screws and more robust latches.

Since that AD was issued, it was determined that aeroplanes that have

embodied Airbus Mod 201938 (Improvement of latching mechanism of potable 

water service panel) are also not affected by the requirements of this AD.

For the reason described above, this AD is revised to exclude post-mod 201938 

aeroplanes from the Applicability.
