What happened
A private pilot operated a recently purchased aircraft for local sightseeing flights over an airport. The flight included rides for bystanders on the ground. During the final segment of the operation, witnesses observed the aircraft executing an aerobatic maneuver consistent with either a loop or an Immelmann turn.
The aircraft climbed to an inverted position as part of this maneuver. However, it fell out of the intended flight path and began to turn counter-clockwise. The aircraft completed two full counter-clockwise rotations before impacting the ground.
