Abstract
A detection system for detecting failure in a primary load path of a flight control actuator and annunciating engagement in a secondary load path of the flight control actuator. The failure in the primary load path causes axial movement in a secondary rod of the secondary load path. The detection system includes a secondary mounting assembly that guides axial movement of the secondary rod; and a sensor that electronically detects relative axial displacement between the secondary rod and the secondary mounting assembly upon a primary load path failure and annunciates transition to engagement in the secondary load path.
