Analysis
The pilot reported that he observed a thin layer of snow that covered his destination runway. He performed a normal approach and landing, but after landing he impacted a snow drift on the runway. The airplane nosed over and came to rest inverted which resulted in substantial damage to the wing and tail structure. The pilot reported no mechanical malfunctions or failures that would have precluded normal operation.
