What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Pilot was hovering over power lines at night searching for a landing area / parking lot with the intent to land. It appears that the down-wash from the main rotor blades caused the power lines to make contact with each other creating a short circuit with a subsequent power failure. An FAA aircraft inspection at the pilots home base confirmed no damage to the helicopter. There was no indication of the heli-copter making contact with the power -lines and the pilot has stated that he never saw the lines until after he saw that the lights were out on an adjacent football field and simultaneously noticed sparks coming out of what appeared to be a transformer.
