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 was conducting aerial observation of his pipeline head gate to check for debris. He overflew the area at 150 feet above ground level (agl) and "observed a light tailwind and no downdraft." He performed a left 360 degree turn and flew over the area a second time between 50 and 60 feet agl. The airplane encountered a "severe downdraft" and settled into terrain. The right wing spar was broken in the impact, as was the right main landing gear and nosewheel. The propeller was destroyed. The pilot reported no mechanical anomalies with the airplane.
