THE AMATEUR BUILT AIRCRAFT WAS CONDUCTING AEROBATIC MANEUVERS WHEN IT DESCENDED INTO THE TERRAIN. A POST ACCIDENT EXAMINATION OF THE AIRFRAME REVEALED THAT THE PITCH (ELEVATOR) CONTROL LINKAGE UNDER THE PILOT'S SEAT, AT THE BELLCRANK, WAS MISSING A BOLT. THERE WAS NO EVIDENCE OF AN INFLIGHT FAILURE IN THIS AREA AND BOTH THE TORQUE TUBE AND ROD END SHOWED NO INDICATION OF DAMAGE. THE BOLT WAS NOT LOCATED.
Probable Cause: IMPROPER MAINTENANCE, BY PERSON OR PERSONS UNKNOWN, TO THE ELEVATOR CONTROL SYSTEM WHICH ALLOWED A BOLT ATTACHING THE ELEVATOR CONTROL ROD TO THE PITCH BELLCRANK TO BECOME DISCONNECTED DURING FLIGHT.
