The pilot reported that, she was on approach to land at a private airpark while nearing the end of civil twilight. She keyed the radio microphone multiple times during the approach but was unsuccessful to activate the airpark’s high intensity lighting. During the approach she initiated a go around when she realized that she had aligned with a road instead of the runway. During the go around, the airplane struck powerlines, impacted terrain, and came to rest nose down against a fence. The right wing and the fuselage were substantially damaged. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. Members of the airpark added that shortly after the accident, the airpark’s runway lights were activated and verified to be operational.
