1. A check device for a flight actuator primary load path failure detection device of the type that disconnects a position sensor from the primary load path in the event of a primary load path failure, the check device comprising:

  • a mechanical linkage for simulating disconnection of the position sensor by permitting relative movement of at least a first mechanical part of the actuator and a second mechanical part of the actuator that are unable to move relative to one another in normal use without failure of the primary load path, wherein the first and second mechanical parts each include a first part with movement detected by the position sensor of the primary load path failure detection device.
