While flying westbound along US Highway 2, the pilot made an elevator input in the homebuilt, experimentally certificated Smith Mini DSA-1 aircraft, and became aware that the control stick had no effect on pitch attitude. After an initial climb, the aircraft transitioned into a descent and the pilot retarded the throttle to idle and bailed out, parachuting safely to the ground. A post-crash examination was unable to locate the one-quarter inch diameter bolt, which connects the control stick push rod to the elevator actuating bellcrank. The loss of this bolt would result in a disconnection between the pilot's control stick and the elevator, and the subsequent inability by the pilot to maintain pitch control of the aircraft.
Probable Cause: The separation/loss of the bolt and castle nut which connected the elevator bellcrank to the control stick pushrod resulting in a disconnect between the cockpit and the control surface and ultimately, the pilot's total loss of pitch control.
