Probable cause

The loss of engine power for undetermined reasons during an aerial application flight and the unsuitable landing area encountered by the pilot during the subsequent forced landing. An additional cause was the low altitude of an aerial application operation.

Analysis

The airplane impacted an agricultural field during an aerial application flight. Examination of the accident site revealed both fuel tanks were broken open and did not contain any residual fuel. There was no "heavy" fuel smell. The propeller blades were deformed rearwards consistent with no power. The flaps were extended. The main landing gear impacted a ditch and were still attached to the airplane. The left wing impacted an embankment.
