Approach and Stall
The pilot reported that he approached the airport midfield from the east, flew over the wind sock, and interpreted the wind direction as originating from the southeast. He then turned the airplane northbound and executed a downwind leg for runway 17.
As the airplane turned from the base leg to final approach, the pilot recognized that the airplane began to 'stall out.' He added full power after the stall began; however, the airplane continued to 'stall and pancake to the ground.' Subsequently, the airplane impacted a chain link fence.
Post-Accident Observations
The pilot reported that he observed the wind sock immediately after the accident, and the winds had changed, indicating winds originating from a northerly direction. He further stated that 5 minutes later he noticed that the winds were once again from the south.
Weather Conditions
The pilot reported the weather conditions as 'moderate turbulence' and 'a lot of updrafts and downdrafts that day.'
