THE PLT THEN MADE 3 HIGH SPEED/LOW ALTITUDE FLY-OVERS ALONG RWY 13. DURING THE 3RD FLY-OVER, THE ACFT WAS OBSERVED TO ROLL TO INVERTED FLT. HOWEVER, WHILE FLYING INVERTED, IT BEGAN TO DESCEND. SUBSEQUENTLY, IT IMPACTED THE GND BESIDE RWY 13, WHILE ON A SE HDG. THE ACFT WAS EXTENSIVELY DAMAGED BY IMPACT & GND FIRE; THE WRECKAGE TRAIL EXTENDED ABOUT 400 FT. WITNESSES RPRTD THE ENGS WERE RUNNING THRU-OUT THE MNVR UNTIL IMPACT. ALSO, WITNESSES RPRTD THAT WHEN THE ACDNT OCCURRED, THERE WAS SOME LIGHT IN THE WEST, BUT THERE WAS DARKNESS TO THE EAST. THE PLT HAD ONLY ABOUT 2 HRS OF DUAL INSTRUCTION IN THIS ACFT, NONE OF WHICH WAS IN AEROBATICS. NO OTHER FLT TIME IN THIS ACFT WAS VERIFIED, THOUGH HE HAD 2 BACK SEAT FLTS IN A SIMILAR MAKE & MODEL OF ACFT.
IMPROPER IN-FLIGHT PLANNING/DECISION BY THE PILOT, AND HIS FAILURE TO MAINTAIN ALTITUDE AND CLEARANCE ABOVE THE TERRAIN, WHILE PERFOMING LOW ALTITUDE, INVERTED FLIGHT. FACTORS RELATED TO THE ACCIDENT WERE: THE LACK OF VISUAL PERCEPTION TO THE PILOT AT DUSK (TWILIGHT), THE PILOT'S OVERCONFIDENCE IN HIS PERSONAL ABILITY, AND HIS LACK OF EXPERIENCE IN THIS AIRCRAFT AND TYPE OF OPERATION.
