Factual narrative
THE PLT RPRTD THAT WHILE HE WAS PERFORMING AEROBATICS AT AN AIRSHOW, THE ACFT'S ENG MOMENTARILY LOST POWER DURING INVERTED FLT AT THE TOP OF A LOOP. HE WAS UNABLE TO COMPLETE THE LOOP. SUBSEQUENTLY, THE ACFT CONTACTED THE RWY IN A LEVEL ATTITUDE WHILE IT WAS STILL DSCNDG IN A HI SPEED STALL. IT BCM AIRBORNE AGAIN, THEN IMPACTED ON ITS RGT WING, CARTWHEELED & CAME TO REST AGAINST THE ARPT PERIMETER FENCE. WITNESSES SAID THERE WAS NO APPARENT ATTEMPT BY THE PLT TO ABORT THE LOOP. ABOUT 'TWO THIMBLES FULL' OF FINE SAND LIKE SUBSTANCE WAS FOUND IN THE SEDIMENT BOWL. NO PREIMPACT PART FAILURE OR MALFUNCTION WAS FOUND.
