The root cause of this defect is due to an incorrect manufacturing process. A spoiler piston rod bearing breakage experienced during aircraft operation can lead to the associated hydraulic system loss and spoiler extension to the zero hinge moment in flight. The spoiler extension generates bank angle and consequently modify the A/C trajectory. The critical consequences are identified for the final approach phase, the magnitude dependant upon the position of the failed spoiler.
