The agricultural airplane was on its first swath run of a boll weevil eradication flight when the engine cowling separated and struck the propeller and engine. The engine lost power, and the pilot executed a forced landing to a cotton field. During the landing roll, the aircraft 'spun' around. The FAA inspector reported that the fractured engine cowling support bracket had a 'dull surface like it had been broken for a while.' Examination of the aircraft's engine revealed that four push rod tubes were bent.
Probable Cause: The separation of the engine cowling due to a fractured support bracket, which resulted in the cowling striking and bending four engine push rods causing a loss of engine power. A factor was the lack of suitable terrain for the forced landing.
