EASA AIRWORTHINESS DIRECTIVE 

AD No.: 2010 – 0066

Date: 21 April 2010

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 Airworthiness Directive applies, except in accordance with the requirements of that 

Airworthiness Directive 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) :

A310 and A300-600 aeroplanes

TCDS Number : France N° 145 

Foreign AD : Not applicable 

Supersedure : None 

ATA 71 Engine Mount – Forward Engine Mount Cast Yoke – 

Inspection/Replacement

Manufacturer(s): Airbus (formerly Airbus Industrie) 

Applicability: 

- A310-204, A310-304 and A310-308 aeroplanes, and 

- A300B4-601, A300B4-603, A300B4-605R, A300C4-605R and A300F4-

605R aeroplanes

Reason: 

Airbus, in the frame of the Extended Service Goal (ESG) exercise, has 

demonstrated by post-certification analysis that, among the types of 

yokes in service, one component on the CF6-80C2 forward engine 

mounts (skinny cast yoke) does not meet the Design Service Goal (DSG) 

requirements. 

This condition, if not corrected, could result in a deterioration of the 

structural integrity of the forward engine mount. 

For the reasons described above, this AD requires operators to perform a 

one time inspection of the forward engine mount skinny cast yokes Part 

Number (P/N) 9383M43G08 , 9383M43G09, 9383M43G10 and 

9383M43G11 of GE CF6-80C2 powered aeroplanes and to replace the 

affected skinny cast yokes with forged yokes. 

Upon replacement of the skinny cast yoke, the General Electric CF6-

80C2 Service Bulletin (SB) 72-0222 must be completed as a prerequisite.

Effective Date: 05 May 2010 

Required action(s) 

and Compliance 

Time(s): 

Required as indicated, unless accomplished previously: 

(1) Within 400 Flight Cycles (FC) after the effective date of this AD, 

identify, for each engine, the (P/N) of the engine forward mount 

yoke in accordance with Airbus Operator Telex (AOT) A310-

71A2036 or A300-71A6029, as applicable to aeroplane model. 

(1.1) If skinny cast yoke P/N 9383M43G08 or 9383M43G09 or 

9383M43G10 or 9383M43G11 are found installed on LH and/or 

RH engine, within the same 400 FC, perform a Detailed Inspection 

(DET) on the forward mount skinny cast yoke in accordance with 

Airbus AOT A310-71A2036 or A300-71A6029, as applicable to 

aeroplane model, and: 

(1.2) Within 30 days following the DET send to Airbus: 

- the Component Movement Traceability Sheet (Appendix 3) of 

AOT A310-71A2036 or A300-71A6029, as applicable to aeroplane 

model, 

- the inspection report (Appendix 2) of AOT A310-71A2036 or 

A300-71A6029, as applicable to aeroplane model. 

(2) If as a result of a DET as required by Paragraph (1.1) of this AD 

the forward mount skinny yoke is found ruptured, before the next 

flight, contact Airbus for approved corrective actions in accordance 

with AOT A310-71A2036 or A300-71A6029, as applicable to 

aeroplane model, and accomplish those actions accordingly. 

(3) If as a result of a DET as required by Paragraph (1.1) of this AD 

the forward mount skinny yoke is not found ruptured, within 7 000 

FC after the effective date of this AD, replace the forward engine 

mount skinny cast yoke with a forged yoke P/N 1806M79G01, in 

accordance with AOT A310-71A2036 or A300-71A6029 as 

applicable to aeroplane model, and accomplish the instructions of 

GE CF6-80C2 SB 72-0222 as a prerequisite if not previously 

accomplished. 

(4) Once forward engine mount skinny cast yoke has been replaced 

by forged yoke P/N 1806M79G01 on an airplane do not install any 

forward engine mount skinny cast yoke P/N 9383M43G08 or 

9383M43G09 or 9383M43G10 or 9383M43G11 on that aeroplane.
