### ATA 71 Engine Mount – Forward Engine Mount Cast Yoke – Inspection/Replacement

Manufacturer(s): Airbus (formerly Airbus Industrie)

Applicability: - A310-204, A310-304 and A 310-308 aeroplanes, and - A300B4-601, A300B4-603, A300B 4-605R, 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, coul d 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.EASA AD No.: 2010-0066

(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 th is 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 (4) Once forward engine mount skinny cast yoke has been replaced by forged yoke P/N 1806M79G01 on an airplane do not install any forward engine mount skinny cast yoke P/N 9383M43G08 or 9383M43G09 or 9383M43G10 or 9383M43G11 on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.
