Analysis

The acft nosed over during an precautionary landing due to deteriorating weather. The plt had received a weather briefing. The wx conditions deteriorated enroute due to a snow storm and the plt elected to land on a private strip to await improved weather. The airstrip seemed hard packed enough when the plt surveyed it from the air and it did hold up the acft until it decelerated. The right wheel sank into the snow at slow speed and the acft nosed over.
