I ssued : 15 June 2016

Note: This Airworthiness Directive (AD) is issued by EASA, acting in accordance with Regulation (EC) 216/2008 on behalf of the European Union , 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 Regulation ( EU ) 748/2012, Part 21.A.3B. In accordance with Regulation ( EU ) 1321/2014 Annex I, Part M.A.301, the continuing airworthiness of an aircraft shall be ensured by accomplishing any applicab le 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 [ Regulation ( EU ) 1321/2014 Annex I, Part M.A.303] or agreed with the Authority o f the State of Registry [ Regulation ( EC ) 216/2008, Article 14(4) exemption]

Reason: On each aeroplane wing, a NACA duct assembly is installed, including a Fuel Vent Protector (FVP) which is used as flame arrestor. This FVP is maintained in its NA CA duct assembly by a circlip (also known as C

- clip). Following a wing water pressure test, the FVP is removed and dried with heat. During an inspection after this test, several circlips were reported to be discoloured. Investigation revealed that a batch of circlips fitted on some FVP Part Number (P/N) 786073

An agency of the European Union Page 2 of 4 This condition, if not detected and corrected, could lead to circlip failure and consequent FVP movement, reducing the fl ame protector capability of the FVP cartridge, possibly resulting in damage to the aeroplane in case of lightning impact or fire on ground.

Airbus issued Service Bulletin (SB) A320

- 28

- 1221, providing instructions for identification by serial number (s/n) and removal from service of the affected FVP P/N 786073

- 1

- 0, and EASA issued AD 2014

- 0234, later revised, to require those actions and to implement installation requirements for the FVP.

After that AD was issued, one step in the FVP re

- installation instr uctions was identified as missing. Consequently, Airbus revised SB A320

- 28

- 1221 to provide instructions for sealant installation on some nuts and bolts on the NACA duct assembly.

For the reasons described above, this AD retains the requirements of EASA A D 2014

- 0234R1, which is superseded, and requires additional work for aeroplanes already modified in accordance with Airbus SB A320

Required Action(s) and Compliance Time(s): Required as indicated, unless accomplished previously:

Restatement of the Requirements of EASA AD 2014

- 0234R1 : Note 1: For the purpose of this AD, an “affected FVP” is a FVP having P/N 786073

- 1

- 0, s/n as listed in Appendix 1 of this AD, and that is not marked with “Amdt B”.

(1) For an aeroplane having a MSN as listed in Table 1 of this AD, within 30 months, or 7 500 flight hours, or 5 000 flight cycles, whichever occurs first since Airbus date of manufacture of the aeroplane, inspect each FVP P/N 786073

- 1

- 0 on the aeroplane to determine whether i t is an affected FVP, and replace each affected FVP with a not affected part in accordance with the instructions of SB A320

– Affected Aeroplanes listed by MSN

5438, 5441, 5444, 5445, 5447, 5457, 5459, 5460, 5461, 5463, 5464, 5469, 5473 to 5478 inclusive, 5481, 5482, 5483, 5485 to 5488 inclusive, 5490 to 5493 inclusive, 5495 to 5505 inclusive, 5507 to 5515 inclusive, 5517, 5518, 5520 to 5527 inclusive, 5530, 5536, 5539, 5541, 5544, 5547, 5551, 5553 and 5556.

(2) For an aeroplane having a MSN not listed in Table 1 of this AD, within 12 months after 07 November 2014 [the effective date of the original issue of AD 2014

- 0234], accomplish the actions as required by paragraph (2.1) and (2.2) of this AD.

(2.1) Determine whether an affected FVP has been installed on that aeroplane after July 2012.EASA AD No.: 201 6

An agency of the European Union Page 3 of 4 (2.2) If, after the determination as required by paragraph (2.1) of this AD, an affected FVP, installed after July 2012, is found, or if no s/n identification can be made, replace that FVP with a not affected part in accordance with the instructions of Airbus SB A320

- 28

- 1221 or contact Airbus for approved instructions and accomplish those instructions accordingly

.
(3) A review of aeroplane delivery or maintenance records is acceptable to identify the FVP s/n, in lieu of the inspection as required by paragraph (1) of this AD, or in lieu of the determination as required by paragraph (2.1) of this AD, as applicable, provided those records can be relied upon for that purpose, and the s/n of the FVP can be conclusively identified from that review.

(4) From 07 November 2014 [the effective date of the original issue of AD 2014

- 0234], it is allowed to install on any aeroplane a FVP P/N 786073
