A system for monitoring for pushrod faults in an aircraft includes a pushrod; a sensor (36) mounted on the pushrod (34), the sensor (36) wirelessly transmitting measured pushrod load data; a receiver (44) receiving the measured pushrod load data; a model (42) receiving flight data and generating a modeled pushrod load profile; and a fault detector (46) comparing measured pushrod load data to the modeled pushrod load profile to detect a pushrod fault.
