General Electric Company CF6-80E1 Series Turbofan Engines
This AD applies to General Electric Company (GE) CF6-80E1 series turbofan engines. These engines are installed on, but not limited to, Airbus Industrie A330 series airplanes.
The FAA is adopting a new airworthiness directive (AD) for General Electric Company (GE) CF6-80E1 series turbofan engines installed on Airbus Industrie A330 series airplanes. This AD requires a check of the holding torque of the thrust reverser actuation system (TRAS) locks, and if necessary a visual inspection of the TRAS lock flexible drive shafts, within 10 flight cycles after all aborted takeoffs in which the thrust reverser was deployed. This AD results from reports of operators finding several damaged TRAS lock flexible drive shafts during inspections and checks of the drive shafts. We are issuing this AD to prevent inadvertent in-flight deployment of the thrust reverser, which can result in loss of control of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified unless the actions have already been done.
(f) Within 10 flight cycles after all aborted takeoffs in which the thrust reverser was deployed, do the following:
(1) Perform a check of the holding torque of the TRAS locks.
(2) Based on the results of the holding torque check, perform a visual inspection of the TRAS lock flexible drive shafts if necessary.
(3) Replace any damaged flexible drive shafts or locks.
(g) Information on performing a check of the holding torque of the TRAS locks, and a visual inspection of the TRAS lock flexible drive shafts, can be found in the Airbus A330 Aircraft Maintenance Manual, Task 72-00-00-200-850.
