Analysis

The pilot reported that, during landing on a road in flat light conditions he drifted to the right after touching down and the right tire struck unplowed snow. The pilot was unable to correct, and the airplane continued to the right into a snow berm. Subsequently, it nosed over sustaining substantial damage to the wings, lift struts, and rudder. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
