EASA AIRWORTHINESS DIRECTIVE

AD No.: 2014-0234R1

Date: 11 December 2014

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):

A318, A319, A320 and A321 aeroplanes

TCDS Number: EASA.A.064

Foreign AD: Not applicable

Revision: This AD revises EASA AD 2014-0234 dated 24 October 2014, including the 

Correction dated 28 October 2014.

ATA 28 Fuel – Fuel Vent Protector – Inspection / Replacement

Manufacturer(s): Airbus (formerly Airbus Industrie)

Applicability: Airbus A318-111, A318-112, A318-121, A318-122, A319-111, A319-112,

A319-113, A319-114, A319-115, A319-131, A319-132, A319-133, A320-211, 

A320-212, A320-214, A320-215, A320-216, A320-231, A320-232, A320-233, 

A321-111, A321-112, A321-131, A321-211, A321-212, A321-213, A321-231 

and A321-232 aeroplanes, all manufacturer serial numbers (MSN).

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 NACA 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) 786073-1-0 have an increased risk of corrosion due to a manufacturing 

quality issue.

This condition, if not detected and corrected, could lead to circlip failure and 

consequent FVP movement, reducing the flame protector capability of the FVP 

cartridge, possibly resulting in damage to the aeroplane in case of lightning 

impact or fire on ground. 

For the reason described above, EASA issued AD 2014-0234 to require 

identification by serial number (s/n) of the affected FVP P/N 786073-1-0 and 

removal from service.

This AD is revised to clarify that only maintenance records since August 2012 

should to be consulted to demonstrate, as required by paragraph (2), that no 

replacement FVP has been installed.

Effective Date: Revision 1: 18 December 2014

Original issue: 07 November 2014

Required Action(s) 

and Compliance

Time(s):

Required as indicated, unless accomplished previously:

Note: The FVP affected by this AD are those having P/N 786073-1-0, having a 

s/n as listed in Appendix 1 of this AD, and are 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 it is an affected FVP, 

and replace each affected FVP with a serviceable part in accordance with 

the instructions of Airbus Service Bulletin (SB) A320-28-1221.

Table 1 - 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, no

action is required by this AD, provided it is determined that no affected 

FVP has been installed on that aeroplane after July 2012.

In case an affected FVP is installed, or no s/n identification can be made,

within 12 months after 07 November 2014 [the effective date of the 

original issue of this AD], replace the FVP with a serviceable part in 

accordance with the instructions of Airbus SB A320-28-1221.

(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) 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 this 

AD], it is allowed to install on any aeroplane a FVP P/N 786073-1-0

having a s/n as listed in Appendix 1 of this AD, provided the FVP is 

marked with “Amdt B”.
