Analysis

According to the pilot in the low-wing, experimental, amateur-built airplane, he landed on a backcountry strip. During the taxi about 15mph, the left wing and the right wing struck separate fence posts. The pilot reported that the fence posts were surrounded by vegetation and not visible. He continued his taxi to parking and shut the engine off. The airplane sustained substantial damage to the leading edge and the ribs on both wings. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
