The helicopter pilot reported that, shortly after liftoff to the north from his property, he saw coyote tracks and "wanted to inspect." To better observe the coyote, he maneuvered at a low altitude, which led him to cross over a power line. After crossing the power line for a third time, he spotted the coyote, turned left, diverted his attention from the power line, continued to turn left, and the main rotor blades struck the power line. He maintained control of the helicopter and landed without further incident.
The helicopter sustained substantial damage to the main rotor blades.
The pilot reported that there were no preimpact mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
Probable Cause: The pilot's failure to maintain clearance from the power lines.
