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, just prior to landing at an off-airport site, he was distracted by sunlight reflecting off a nearby river. As the main landing gear touched down, the right wing hit a tree root, and the rear wing spar sustained substantial damage. The pilot indicated that there were no preaccident mechanical anomalies with the airplane. He stated that the accident could have been prevented had he landed the opposite direction because there were no obstacles on that approach.
