The NTSB's narrative final · quoted from the NTSB record

The helicopter impacted power lines while departing from an automobile accident scene. The helicopter was part of a two aircraft team dispatched to the scene of the automobile accident. During the landing approach, the pilot noticed the power lines running parallel to the road; however, he did not consider them to be an unusual hazard at the time. After the passengers were loaded into the helicopter, the pilot took off, drifted toward the wires, and impacted the power lines. The pilot then landed the helicopter in an adjacent field. The pilot stated that at the time the helicopter impacted the wires 'the sun was shining directly into the aircraft' and that 'trash was blowing around.' Another helicopter was dispatched to the scene of the accident to transport the patients to the hospital.
