Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that he was participating in a "bean bag drop" competition at the airfield. He was flying from the left seat while his right-seat passenger was to drop the bean bag onto the target. He overflew the runway at 70 feet above the ground and banked right to see where the bean bag landed. There was a left-to-right crosswind that pushed him farther right than anticipated. As the airplane approached tall trees at the edge of the airfield, the pilot banked further right to avoid them. The airplane stalled, descended, and collided with the ground. The airplane sustained substantial damage to the fuselage and wings. The pilot reported no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
