Probable cause

The pilot’s failure to maintain airplane control while maneuvering at low altitude shortly after takeoff.

NTSB narrative

Witnesses reported that shortly after takeoff, the airplane was about 200 to 300 feet above the ground when it made a sudden right turn and banked about 90 degrees. Some witnesses reported that they heard a reduction in engine power just before the right turn followed by an increase in engine power. During the turn, the airplane appeared to stall and enter a spin. The airplane impacted terrain and a fire ensued. Postaccident examination of the airframe and engine revealed no preimpact mechanical failures or malfunctions that would have precluded normal operation.
