AIRBUS INDUSTRIE
A310 and A300-600 Aircraft
CF6-80C2 engine aft mount L/H link (ATA 71 )
1. APPLICABILITY:
AIRBUS INDUSTRIE A310 and A300-600, all certified models and all serial numbers fitted with General Electric CF6-80C2 engines.
2. REASON:
This Airworthiness Directive is prompted by a failure of the aft engine mount left link of a CF6-80A3 engine discovered during a scheduled engine removal.
Analyses have shown that the same phenomenon could affect CF6-80C2 engines. This can lead to the aft engine attachment separation with subsequent possibility of engine pivoting and in the worst case its separation.
3. MANDATORY ACTION AND COMPLIANCE TIME:
To prevent a CF6-80C2 engine aft attachment failure, the following measure is rendered mandatory from the effective date of this Airworthiness Directive :
-before January 26th, 1999, unless accomplished previously, apply the actions described in the General Electric Aircraft Engines Alert Service Bulletin CF6-SOC2 S/B 72-A947.
