Analysis

The pilot was spraying a field approximately 10 feet agl parallel to telephone lines. The main rotor blades clipped the telephone lines and the helicopter descended into the ground. The skids became embedded in a row of irrigation pipes and the aircraft nosed over and came to rest inverted. The pilot reported that there were no mechanical malfunctions with the aircraft prior to the accident.
