What happened
The pilot conducted two separate approaches toward the east end of a grass airstable. During the initial approach, the pilot performed a touch-and-go maneuver. On the second approach, the aircraft did not make contact with the ground but instead maintained a low altitude while flying over the length of the runway.
At the conclusion of this second approach, the pilot executed a steep pull-up, gaining an altitude of several hundred feet. Following this climb, the pilot entered a steeply banked right turn to reverse course. After completing the reversal, the pilot initiated a rapidly descending slip directed toward the west end of the runway. Immediately after terminating the slip, the aircraft struck 40-foot-high power lines situated approximately 20 feet from the runway threshold.
