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, she set up for a normal approach to runway 17. Just before initiating the landing flare, transitioning through an altitude of about 15 ft above ground level (agl), the airplane encountered a wind gust. The left wing lifted to a near vertical attitude and the pilot manipulated the throttle full forward to go-around. The airplane was too low to avoid the trees adjacent to the runway. The wings were substantially damaged when the airplane collided with several trees and came to rest nose-low with the nose gear collapsed. The pilot reported that there were no pre impact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
