Unsafe Condition
desynchronization of one of the three rudder servo actuators, which, if combined with an engine failure, could result in the loss of the related hydraulic system and could cause the loss of one of the two synchronized actuators. This condition could create additional fatigue loading and possible cracking of the attachment fittings and could result in the inability of the remaining synchronized actuator to maintain the commanded rudder deflection, leading to reduced controllability of the airplane.
