Probable cause
The total loss of engine power due to separation of a carburetor air box support bracket and subsequent airflow obstruction to the carburetor.
NTSB analysis
During an aerial application flight, the engine started to lose power. The pilot elected to perform a precautionary landing to a field. During the precautionary landing, he observed a fence and berm ahead and added power to go over the fence; however, the engine lost all power. During the forced landing, the airplane hit the fence. The postaccident engine examination revealed that a support bracket in the carburetor air box separated and entered the carburetor. The separated piece blocked the venturi and obstructed the airflow within the engine, resulting in the subsequent loss of engine power. An examination of the remaining engine and airframe systems revealed no anomalies.
