Analysis

The pilot said that after completing an EMS mission, while enroute back to the home base, he thought he saw smoke on the ground, and decided to make a closer, visual check. Cruising initially at 1000 AGL, he began a cruise descent to better inspect the smoke. The helicopter struck power lines about 60 feet AGL. An emergency autorotation was attempted and a hard landing was made in a shallow river.
