Analysis

The acft was seen to fly erratically before plunging into the lake during an landing attempt. Investigation revealed a history of pre-existing medical problems that could lead to 'a convulsive episode with accompanied loss of consciousness.' An examination of the electrical system revealed that the left magneto was inoperative due to an internally shorted condenser.
