EASA AIRWORTHINESS DIRECTIVE

AD No.: 2013-0202

Date: 05 September 2013

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

Supersedure: This AD supersedes EASA AD 2011-0202 dated 13 October 2011.

ATA 32 Landing Gear – Landing Gear Control and Interface Unit Wiring –

Modification

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, A320-111, 

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.

Reason: After a push back from the gate, an A320 aeroplane was preparing to initiate

taxi, when an uncommanded nose landing gear (NLG) retraction occurred,

causing the nose of the aeroplane to hit the ground. Investigations revealed

that the retraction was caused by a combination of a power interruption to

Landing Gear Control and Interface Units (LGCIU) and an internal hydraulic 

leak through the landing gear (LG) selector valve 40GA.

Deeper investigations have revealed that LGCIU power interruption appears

during engine start at each flight. Even though no incident has been reported in 

service, it has been determined that a non-compliance to the safety objective 

exists when combined with a dormant single failure of the selector valve seal 

leaking.

This condition, if not corrected, could lead to further incidents of untimely

unlocking and/or retraction of the NLG which, while on the ground, could result 

in injury to ground personnel and damage to the aeroplane.

To address the possible hydraulic leak of the LG selector valve, EASA issued

AD 2007-0065, currently at Revision 2.

To address the risk of untimely unlocking and/or retraction of the NLG, EASA 

issued AD 2011-0202 to require installation of a power interruption protection 

circuit to the LGCIU and accomplishment of associated modifications.

Since that AD was issued, it has been discovered that additional work is 

necessary to adequately correct this unsafe condition and consequently, Airbus 

issued Service Bulletin (SB) A320-32-1346 to Revision 05. An update of the 

maintenance programme is required as well, following the required 

modification.

For the reason described above, this AD retains the requirements of EASA AD 

2011-0202, which is superseded, and requires certain additional actions, as 

defined in the revised Airbus SB, as applicable to aeroplane model, and an

update of the approved maintenance programme.

Effective Date: 19 September 2013

Required Action(s) 

and Compliance

Time(s):

Required as indicated, unless accomplished previously:

(1) Within the compliance time as specified in Table 1 of this AD, as applicable 

to aeroplane configuration, modify the aeroplane in accordance with the

(A319CJ) aeroplanes, in accordance with the instructions of Airbus SB 

A320-32-1349 Revision 03, as applicable to aeroplane model.
