APRX 15 MIN AFTER THE PLT TOOK OFF, HE WAS FLYING OVER THE airport AT ABOUT 400 FT AGL WHEN WITNESSES HEARD A 'LOUD NON-METALLIC' SOUND FROM THE VEHICLE. AT ABOUT THAT TIME, IT ENTERED A LEFT DESCENDING TURN. REPORTEDLY, THE VEHICLE MADE ABOUT 3 TURNS, AND DURING EACH TURN, THE BANK ANGLE INCREASED. AT APRX 200 FT AGL, THE PLT RELEASED HIS PARACHUTE, BUT THE CANOPY NEVER BLOSSOMED.THE VEHICLE IMPACTED IN A LEFT WING DOWN, NOSE LOW ATTITUDE. AN EXAM REVEALED THAT THE RIGHT WING FABRIC WAS TORN IN A MANNER THAT WAS CONSISTENT WITH AN IN-FLT SEPARATION. THE OUTBOARD COMPRESSION SUPPORT TUBE WAS FOUND 15 FT FROM THE MAIN WRECKAGE.
