Read the full NTSB narrative

On the day prior to the accident, the pilot performed a solo air show flight, and the engine lost power during the taxi after landing. No anomalies were noted that caused the loss of engine power. About one hour prior to the accident flight, the pilot performed a solo air show flight with no anomalies. After the solo flight, the airplane was refueled, and the pilot performed the wing walker performance. Approximately 5 minutes into the performance, the engine lost power. The airplane impacted terrain adjacent to the runway and a postimpact fire ensued. The wing walker, who was located in the front area of the fuselage, sustained multiple burns, and succumbed to her injuries approximately 2 months after the accident. Postaccident examination of the engine and its fuel system revealed no anomalies that would have precluded normal operations. Video and photographic evidence showed from the engine exhaust, prior to the loss of engine power, which can indicate a flooded condition; however, the reason for the flooded condition and loss of engine power could not be determined.
