A drive assembly is operable to move control surfaces on wings of an aircraft. The drive assembly may include a gear reduction assembly which is driven by a pair of motors. The drive assembly has output members which are connected with the control surfaces on the wings of the aircraft. Torque limiting brake assemblies are operable between an engaged condition in which they are effective to prevent rotation of output members and a disengaged condition in which the brake assemblies are ineffective to prevent rotation of the output members. Actuator assemblies are connected with the torque limiting brake assemblies. The actuator assemblies are operable to effect operation of the torque limiting brake assemblies from a disengaged condition to an engaged condition in response to transmission of predetermined torques through the actuator assemblies to the output members. The drive assembly may also include one or more shock absorbing clutch assemblies which absorb the kinetic energy of the motors when the torque limiting brake assemblies are actuated to the engaged condition preventing rotation of the output members.
