The NTSB's narrative final · quoted from the NTSB record
The pilot had completed a swath run, and was maneuvering for another swath run, when he experienced problems in controlling the airplane in a right turn. He reported 'the high wing (left wing) very violently came over the top like a snap roll.' This had occurred on the previous two right turns. On the third turn, he made an extended turn with 'plenty' of airspeed, and prevented the wing from going all the way over by applying full left forward stick and left rudder. The airplane descended rapidly. The pilot reported that the airplane 'stalled' just before impact; however, he stated it did 'not stall during the [right] turn.' The pilot also reported that the wind was out of the northeast at 5 knots gusting to 10 knots, and that he possibly encountered wind shear. Examination of the airplane and engine did not disclose any mechanical anomaly. Control continuity was established to all flight controls.
