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, during an instrument meteorological conditions flight, he chose to accomplish an area navigation approach. He reported that he descended to his minimum descent altitude of 800 ft, decreased the airspeed, and began looking outside the cockpit for the runway. He recalled that the visibility was 3/4 mile, and that, about 20 seconds later, the airplane struck tree tops. The pilot immediately executed the missed approach procedure and made an approach to an alternate airport. The right wing sustained substantial damage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
