A helicopter struck power lines while departing from an automobile accident scene. The pilot had noted the wires during approach but did not consider them a hazard. The aircraft landed in a field; another helicopter was dispatched for the patients.

Incident Details

A helicopter involved in a two-aircraft team response to an automobile accident scene struck power lines during departure. The helicopter had been dispatched along with another aircraft to assist at the site of the crash. During the landing approach, the pilot observed power lines running parallel to the road but did not view them as an unusual hazard at that time.

After passengers were loaded onto the helicopter, the pilot initiated takeoff. The aircraft drifted toward the wires and subsequently impacted the power lines. The pilot then managed to land the helicopter in an adjacent field.

Pilot's Account

The pilot reported that at the moment of impact with the wires, "the sun was shining directly into the aircraft" and that "trash was blowing around." These conditions may have affected visibility during the maneuver.

Response

Following the incident, another helicopter was dispatched to the scene of the automobile accident to transport the patients to the hospital.
