The NTSB's narrative final · quoted from the NTSB record

Witnesses reported seeing the airplane performing aerobatic maneuvers just prior to the accident. As the airplane was completing a loop, it impacted terrain in a wings level, nose high attitude. There was no evidence of pre-impact mechanical malfunctions observed during the subsequent examination of the engine or the control system that would have precluded normal operation.
