On short final, the crew noticed that the airplane had restricted up-elevator movement. They initiated a go-around and used power to control pitch for landing. Excessive descent rate and airspeed resulted in a hard landing. Postincident examination revealed a loose upper elevator stop bolt that had contacted a stringer, preventing further movement of the control column. Sixteen flights earlier, maintenance records show extensive work done to the elevator quadrant. During this work, hardware was 'loosely installed' on the quadrant so as to not be lost. The position of a nut run down on the bolt is close to the appearance of a nut properly torqued.
Probable Cause: inadequate maintenance installation and inspection of the elevator flight control system which led to restricted flight control elevator movement due to a loose bolt.
