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 departing to the southwest in the tailwheel-equipped airplane. He reported that shortly after liftoff the airplane encountered a gust of wind that "blew the aircraft sideways." Despite the pilot's control inputs, he was unable to recover and the airplane impacted the ground in a nose-low, right bank attitude. The airplane sustained substantial damage to both wings and fuselage. The pilot reported that the winds at the time of the accident were from 200 degrees at 13 knots, gusting to 37 knots. The pilot reported that there were no mechanical deficiencies with the airplane prior to the accident. He noted in his written statement that the accident could have been prevented if he had postponed the departure until wind conditions improved.
