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 planned to depart from a 2,250 ft turf/gravel runway with expected wind conditions of 5 to 10 knots. After he arrived to the airplane, the pilot observed high wind conditions, with gusts to 40 knots. The pilot elected to depart and as the airplane passed over trees during the initial climb, he noticed high, gusty wind conditions, which he made full control inputs to counter. The airplane entered into sink and it subsequently impacted terrain, which resulted in substantial damage to the right wing and right horizontal stabilizer. The pilot reported that there were no mechanical malfunctions or failures that would have precluded normal operation, and that he should have delayed the departure based on the high wind conditions.
