Analysis

As the pilot made a spray pass over a rice field the engine began backfiring, then lost power. The pilot jettisoned the chemical and attempted to land on a dirt road. The airplane collided with trees as he maneuvered for landing. Post accident engine examination revealed a crack in the number 4 cylinder near the exhaust valve.
