EASA AIRWORTHINESS DIRECTIVE 

AD No.: 2009-0108 

Date: 05 May 2009 

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 EC 1702/2003, Part 21A.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]. 

Type Approval Holder’s Name : 

AIRBUS

Type/Model designation(s) : 

A340 aeroplanes 

TCDS Number : EASA.A.015 

Foreign AD : Not applicable 

Supersedure : None 

ATA 71 Power Plant – Forward Engine Mount Thrust Links - Inspection 

Manufacturer(s): AIRBUS (formerly AIRBUS INDUSTRIE) 

Applicability: AIRBUS A340 model -211, -212, -213, -311, -312 and -313 aeroplanes, 

all serial numbers. 

Reason: A review of A340 missions has demonstrated that CFM56-5C forward 

engine mount thrust links fitted with oversized bearing will not reach the 

updated link fatigue life limit of 15 500 Flight Cycles (FC) due to an 

increase in bore diameter. 

Oversized bearing repairs have been possible through the 

accomplishment of CMM 71-21-12 Repair 1. The consequent potential 

failure of the affected thrust link would reduce the forward engine mounts 

structural integrity and could eventually lead to engine separation, 

constituting an unsafe condition. 

Consequently, this AD requires : 

- the inspection of the link assembly to identify a possible oversized 

bearing repair and, in case of finding, the application of the associated 

corrective actions, or 

- the repetitive inspection of the forward engine mounts until 

accomplishment of the inspection of the link assembly for the 

identification of a possible oversized bearing repair.

Effective Date: 19 May 2009 

Required action(s) 

and Compliance 

Time(s): 

Required as indicated : 

Within 1 700 FC or 24 months from the effective date of this AD, 

whichever occurs first, apply the actions defined in paragraph 1. OR

paragraph 2. of this AD: 

1. Unless already accomplished, inspect the link assembly for oversize 

bearing repair in accordance with the instructions of AIRBUS Service 

Bulletin (SB) A340-71-4007. 

1.1. If oversized bearings are found installed, before next flight contact 

Goodrich to get appropriate instructions and apply them. 

1.2. If oversized bearings are not found installed, no further action is 

required by this AD. 

2. Perform a detailed inspection of the forward engine mounts and 

thereafter repeat the inspection at intervals not exceeding 1 700 FC or 

24 months, whichever occurs first, from the last inspection until 

accomplishment of the inspection defined in paragraph 1. of this AD, 

which must occur no later than 4 500 FC from the effective date of this 

AD, and apply the associated corrective actions in accordance with the 

instructions of AIRBUS SB A340-71-4007.
