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 the approach to land, the sun was directly in his eyes. He added that the airplane drifted to the left and the left wing struck a tree. The airplane continued to the left, struck more trees, and came to rest off the left side of the runway. The airplane sustained substantial damage to both wings and the fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
