Probable cause

The pilot failed to maintain minimum required airspeed for slow flight (vs), resulting in a stall with insufficient altitude to recover. A contributing factor was the Piper pilot's unannounced fly-by, which diverted the Cessna pilot's attention.

Analysis

The pilot was descending his airplane while in slow flight with 10 degrees flaps in a downwind track to look at property that he planned to purchase. A second airplane flew by his airplane at the low altitude and banked away sharply. The accident airplane's wings wobbled, the nose dropped and it impacted into an open wheat field.
