Unsafe Condition
The spoiler actuators installed in positions No. 3 to 7 on A300-600 and A300-600ST aircraft have a defined life limit of 55,750 flight hours. Due to Extended Service Goal (ESG) activities, this life limit can be reached in service, potentially leading to the loss of controllability of the aircraft if all three hydraulic circuits are impacted by affected actuators.

Required Actions
Replace the spoiler actuators with serviceable units before exceeding the life limit of 55,750 flight hours. Use Smiths Service Information Letters SIL 27-01 and SIL 27-02 to calculate the total flight hours accumulated on each spoiler actuator.
