Analysis

According to the pilot, during a landing at an airstrip, he did not realize that he was not centered on the airstrip. The pilot reported that the left wing tip struck a tree during the approach to land. He reported that he tried to control the airplane after the initial impact, however the left wing impacted a second tree, and the airplane collided with the terrain coming to rest in the brush. The airplane sustained substantial damage to both wings. The pilot reported that there were no mechanical failures or anomalies prior to or during the flight that would have prevented normal operation.
