Accident Overview
The pilot was engaged in practicing acrobatic maneuvers when the incident occurred. Ground witnesses reported that after completing a series of maneuvers, the aircraft entered a spin. The aircraft subsequently recovered from the spin, but during the recovery, the left wing struck the ground. The impact caused an explosion, and a post-impact fire incinerated the cabin/cockpit area.
Witness Accounts
Witnesses on the ground stated that the engine was producing power throughout the series of maneuvers. They observed the spin and the subsequent recovery before the wing struck the ground.
Investigative Findings
Investigators established continuity of the empennage flight controls to the cabin/cockpit area, indicating that control cables remained intact. Examination of the propeller blades showed evidence of rotation at the time of impact, consistent with the engine producing power. No other specific findings were reported.
