Unsafe Condition

Failure of the MLG retraction actuator sliding rod at a number of operating flight cycles lower than the limit value imposed by the MLG manufacturer. This can result in undampened extension of the MLG, leading to higher than usual loads on the MLG attachment, affecting structural integrity and potentially causing MLG failure.

Required Actions

Inspect the MLG retraction actuator sliding rod for defects using a detailed and high frequency eddy current inspection. Replace the MLG retraction actuator if defects exceed specified criteria. Perform repetitive lubrication tasks as required by the revised Airbus A300 Aircraft Maintenance Manual.
