Analysis

The pilot stated that he was spraying a rice field and flying into the early morning rising sun. He reported that he did not see the power lines or poles due to the sun glare. After the collision, the pilot noted some control difficulties and attempted a run-on landing. The helicopter skids dug into the soft soil and the helicopter nosed over.
