There were no injuries to the private pilot, nor his passenger, and the helicopter was substantially damaged. The flight was originating at the time. According to the pilot, the helicopter was landed on a street in a residential area.

After the collision, directional problems were experienced with the helicopter and an autorotation was made back to the street, which resulted in a hard landing.
