Analysis narrative
The airplane was observed to enter the traffic pattern on an upwind leg, then turn left on the crosswind leg. However, it remained in the turn which increased in bank, and it started to descend. No change in power was heard as the airplane continued to turn and descend. It struck the ground in a left wing low attitude after completing over 180 deg of turn. The pilot was being treated for high blood pressure. In addition, the autopsy revealed extensive coronary artery disease and evidence of previous heart attacks.
