A system and methods for actuator fatigue monitoring is disclosed. At least two measured actuator forces are received from at least two actuators respectively, and a hybrid force is calculated. The hybrid force is calculated based on a force fight of the at least two actuators calculated based on the at least two measured actuator forces, and a monitored actuator force among the at least two measured actuator forces. An air load of the at least two actuators is estimated based on the at least two measured actuator forces, and a fatigue anomaly is determined based on the hybrid force and the air load.
