A flight control system uses a governor configured to regulate the speed of a rotor in the aircraft through collective pitch control of a rotor blade, and a limiter configured to selectively remove the threshold limit of the governor when the collective pitch control exceeds a threshold limit, so as to permit a pilot full command of the collective above the threshold limit. A buckling restraining assembly is included for maintaining the structural integrity of the brace after the core member has undergone plastic deformation. The plastic sleeve includes a cap portion and an sleeve portion, the cap portion disposed on the top side of the metallic washer coincident with the head of the pin.
