Claim 11:
12. A linear actuator for moving a control surface, the actuator comprising:
an actuator housing;
a nut and screw assembly mounted with respect to the actuator housing and having a screw that is rotatably drivable about a longitudinal axis to drive a nut assembly along the longitudinal axis; and
a load detent assembly including
an engagement member integral with the screw for common rotation through at least 360 degrees of rotation in either direction of rotation, and
a load detent supported with respect to the actuator housing and having a stoppage member selectively movable relative to the longitudinal axis between a releasing position released from the engagement member and an engaging position interengaged with the engagement member and restricting rotation of the screw relative to the actuator housing,
an actuator when activated for selectively moving the stoppage member from the engaging position to the releasing position, and
wherein the stoppage member is selectively movable by activation of the actuator against a biasing force acting on the load detent that urges the load detent toward the engagement member.
