Read the full NTSB narrative

THE ULTRALIGHT WAS OBSERVED BY WITNESSES ON THE DOWNWIND LEG OF THE TRAFFIC PATTERN FOR LANDING. THE ACFT WAS FLYING LEVEL AT ABOUT 300 FT AGL WHEN IT STARTED A SERIES OF ROLLER-COASTER MANEUVERS WHICH INCREASED INTO A STEEP ASCENT AND NOSE OVER FOLLOWED BY A DESCENDING DIVE INTO THE GROUND. THE ENGINE NOISE, WHICH SOUNDED AS IF IT WERE AT FULL POWER, DID NOT CHANGE NOR DID ANY OF THE OBSERVERS SEE ANY OBJECTS FALL FROM THE ACFT. A PARACHUTE WORN BY THE PLT WAS NOT DEPLOYED. POST ACCIDENT EXAMINATION OF THE WRECKAGE DID NOT REVEAL ANY PREIMPACT FAILURES OF THE AIRFRAME OR ENGINE. THE AUTOPSY DID NOT REVEAL ANY PREIMPACT CONDITIONS WHICH WOULD HAVE INTERFERED WITH THE PLTS CONTROL OF THE VEHICLE.
