Claim:
1. An actuation system for a flight control surface of an aircraft, comprising: a support frame for supporting a flight control surface, the support frame being configured to be mounted to an airframe structure of the aircraft for movement between a first position and a second position to move and operate the control surface; an actuation mechanism configured to effect movement of the support frame between the second position and the first position; and a detection device for detecting a problem or a fault in the actuation mechanism, the detection device comprising a deflector configured to deflect or skew the support frame away from or out of the first position in the event of a problem or fault in the operation of the actuation mechanism, wherein the deflector comprises at least one biasing member for generating a biasing force acting against a moving force of the actuation mechanism to deflect or skew the support frame out of the first position.
