Patent ID: 7607611

Claim:
A flight control surface actuation system, comprising: a first flight control surface actuator adapted to couple to a flight control surface and a static airframe structure, the first flight control surface actuator further adapted to receive a drive force and operable, upon receipt thereof, to move between at least an extended position and a retracted position; a second flight control surface actuator adapted to couple to the flight control surface, the second flight control surface actuator further adapted to receive a drive force and operable, upon receipt thereof, to move between at least an extended position and a retracted position; a pivot arm rotationally coupled to, and configured to pivot relative to, the second flight control surface actuator, and directly rotationally mounted on, and configured to pivot relative to, the static airframe structure; and a pivot arm lock movable between a locked position, in which the pivot arm lock prevents rotation of the pivot arm, and an unlocked position, in which the pivot arm lock does not prevent rotation of the pivot arm.
