Analysis

According to the pilot, prior to landing on a dry lake bed, he made one low pass to assess the area where he intended to land. He reported that upon touch down, the wheels broke through the hard layer of the landing surface and there was mud underneath. The main landing gear wheels dug into the mud and the airplane nosed over. The airplane sustained substantial damage to the rudder. The pilot reported that there were no mechanical anomalies or malfunctions during the flight with any portion of the airplane that would have prevented normal flight operations.
