Probable cause

Improper in-flight planning/decision by the pilot and his failure to maintain airspeed, which resulted in an inadvertent stall/mush onto snow covered terrain beside the runway. The adverse weather conditions and snow covered terrain were related factors.

Analysis

The pilot missed his first (sdf) approach & diverted to another airport, where he missed an ILS approach. En route to a 3rd airport, he passed over his original destination & obtained visual contact with the airport. He stated he flew the length of the runway to check visibility & noticed a cloud near the approach end. He entered a down wind leg for runway 34 & turned base approximately half way down the runway length. During a tight turn from base to final approach, the airplane stalled/settled to the ground. It subsequently touched down on snow covered terrain off the left side of the runway, damaging the landing gear, belly & prop.
