Narrative:While applying herbicide to a rice field, during the pull up at the end of a spray pass, the agricultural airplane's engine lost power. During the ensuing forced landing, the airplane touched down in a field and rolled into a hedgerow of trees. Examination of the engine by a mechanic revealed a discontinuity in the propeller governor control. The threads on the push-pull rod which retain the rod end that bolts to the propeller governor were stripped, and the rod end had separated from the rod. According to the mechanic, the separation of the rod end probably resulted in the reported loss of engine power, since the governor is 'spring loaded' to a high pitch (low rpm) setting. No other discrepancies with the engine were noted, and it was placed on a test stand and ran 'with no problems.'
Probable Cause: The partial loss of engine power due to the disconnection of the propeller governor control as a result of the stripped threads on the propeller governor control push-pull rod. A factor was the lack of suitable terrain for the forced landing.
