## Analysis

THE ACFT COLLIDED WITH THE GROUND WHILE PERFORMING AEROBATIC MANEUVERS. THE PLT HAD SCHEDULED A NUMBER OF AEROBATIC FLTSFOR VARIOUS PEOPLE. DURING THE LAST FLT OF THE DAY THE AIRCRAFT CRASHED IN A ALT OPEN, PLOWED FIELD. WEATHER WAS NOT A FACTOR. THE AIRCRAFT IMPACTED THE GROUND IN A 30 DEGREE NOSE DOWN ATTITUDE AND TRAVELED FORWARD 35 FT AFTER IMPACT. THE EMPENNAGE WAS NOT DAMAGED. THE WINGS WERE DESTROYED BUT REMAINED ATTACHED TO THE FUSELAGE. THE ACFT REMAINED UPRIGHTTHE ENGINE REMAINED ATTACHED BUT THE ENGINE MOUNT WAS COLLAPSED. THE FLOOR AND THE LANDING GEAR WERE COLLAPSED. THE INTEGRITY OF THE FLT CONTROL SYSTEM WAS ESTABLISHED. THERE WAS NO EVIDENCE OF AN IN-FLT FAILURE OF THE STRUCTURE OR POWERPLANT. THE OCCUPANTS HAD WORN THEIR SEAT BELTS AND SHOULDER HARNESS WHICH WERE INTACT. BOTH OCCUPANTS RECEIVED FATAL TRAUMATIC INJURIES. THERE WAS NO EVIDENCE OF PRE-IMPACT FACTORS WHICH MIGHT HAVE DETRACTED FROM THE PLTS ABILITY TO OPERATE THE ACFT. THE TOXICOLOGICAL REPORTS FOR BOTH OCCUPANTS WERE NEGATIVE FOR DRUGS AND ALCOHOL.
