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 despite the winds being calm at the surface, shortly after departing for the accident flight he encountered gusty wind above the trees near the airport. He continued around the traffic pattern and planned to land in an area of grass next to the paved runway. During the final approach to land, a sudden gust of wind pushed the airplane to the right of the runway toward trees and a hangar. The pilot described that there was not enough time to initiate a go around before the airplane contacted a tree and then the hangar. The airplane came to rest upside down on the ground and the fuselage and both wings were substantially damaged. The pilot reported that there no preimpact mechanical malfunctions or failures of the airplane that would have precluded normal operation.
