EASA AIRWORTHINESS DIRECTIVE

AD No.: 2015-0088R1

Date: 02 June 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):

A318, A319, A320 and A321 aeroplanes

TCDS Number: EASA.A.064

Foreign AD: Not applicable

Revision: This AD revises EASA AD 2015-0088 dated 22 May 2015, which cancelled DGAC 

France AD 95-203-072 dated 11 October 1995; and superseded DGAC France 

AD 2001-508 dated 17 October 2001, and AD F-2004-147 (EASA approval ref. 

2004-8601) dated 18 August 2004.

ATA 27 Flight Controls – Elevator Aileron Computers – Replacement / 

Software Update

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: The latest elevator aileron computer (ELAC) standard, L97+, implements

enhanced Angle of Attack (AOA) monitoring in order to better detect cases of

AOA blockage, including multiple AOA blockage.

Two ELAC L97+ versions are currently available, Part Number (P/N)

3945129109 with data loading capability, and P/N 3945128215 without the 

data loading capability. Three existing ADs requiring installation of earlier 

ELAC (software) have been identified and taken into account for cancellation 

by this new AD.

For the reasons described above, EASA issued AD 2015-0088, cancelling

DGAC France AD 95-203-072 (no requirements retained), and partially 

retaining the requirements of DGAC France AD 2001-508, and AD

F-2004-147 (EASA approval ref. 2004-8601), which were superseded, and to 

require replacement of all ELAC with ELAC L97+ standard.

Since that AD was issued, some errors were detected in Appendix 1 of the 

AD, and one P/N ELAC was inadvertently omitted. This AD revises EASA AD 

2015-0088 to correct these errors and to add clarification to paragraph (7).

Restatement of (part of) the requirements of DGAC France AD 2001-508:

(1) For certain A319 and A320 aeroplanes, as identified by MSN in Airbus 

Service Bulletin (SB) A320-27-1135, before 31 December 2002, replace 

all ELAC L80 units with ELAC L81 standard units in accordance with the 

instructions of Airbus SB A320-27-1135.
