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 commercial pilot was attempting to depart from a turf runway in gusting, left-quartering headwind conditions. He applied full power and was utilizing a soft-field takeoff technique. As the airplane began to lift off, it encountered a “large wind gust” from the left and departed the runway to the right. The pilot’s remedial actions had “no effect,” and the airplane impacted a row of hangars that ran parallel to the runway. The airplane was destroyed by impact damage and a postcrash fire. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have prevented normal operation.
