The pilot was landing to the west, on a private, grass airstrip. He stated that as the airplane touched down, he became blinded by the setting sun that was located low on the horizon. The airplane subsequently veered to the right into a tree line, which resulted in substantial damage to both wings and the right main landing gear. The pilot reported that he did not experience any preaccident malfunctions or failures that would have precluded normal operation of the airplane. Winds reported an airport that was located about 30 miles north of the accident site, around the time of the accident, were from 360 degrees at 7 knots.
