Airworthiness Directive

AD No.: 2016-0114

[Correction: 23 June 2016]

Issued: 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 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 [Regulation (EU) 1321/2014 Annex I,

Part M.A.303] or agreed with the Authority of the State of Registry [Regulation (EC) 216/2008, Article 14(4) exemption].

Design Approval Holder’s Name:

AIRBUS

Type/Model designation(s):

A318, A319, A320 and A321 aeroplanes

Effective Date: 29 June 2016

TCDS Number(s): EASA.A.064

Foreign AD: Not applicable

Supersedure: This AD supersedes EASA AD 2014-0234R1, dated 11 December 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. 

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 instructions 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 AD 2014-0234R1, which 

is superseded, and requires additional work for aeroplanes already modified in accordance with 

Airbus SB A320-28-1221 original issue or Revision 01.

This AD is republished to remove a misleading adjective in paragraph (5) or the Required Action(s) 

and Compliance Time(s).

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 it is an 

affected FVP, and replace each affected FVP with a not affected part in accordance with the 

instructions of 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, 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.

(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 786073-1-0 having a s/n as listed in Appendix 1 of this AD, 

provided the FVP is marked with “Amdt B” (see Note 2 of this AD).

Note 2: Accomplishment of ZODIAC Aerotechnics SB 786073-28-002, original issue, is an acceptable 

means to upgrade the FVP with Amdt B.

New Requirements of this AD:

(5) For an aeroplane on which an FVP was visually inspected or replaced in accordance with the 

instructions of SB A320-28-1221 original issue or Revision 01, within 6 months after the 

effective date of this AD, apply sealant on nuts and bolts of the NACA duct assembly, on which 

that FVP is installed, in accordance with the instructions defined as “Additional Work” in SB 

A320-28-1221, Revision 2.
