What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23)While on a glider pleasure flight with a non pilot passenger the aircraft struck a powerline. The pilot reported that his approach was inititally too high. He added flaps and extended spoilers in an effort to correct the high approach. Once established on a normal glide path then encountered an unexpected sink rate. The pilot retracted spoliers and increased airspeed trying to clear the powerlines. He stated that, at the time, he believed his corrective action would clear the lines and allow a normal landing. The glider continued to sink until it struck the powerlines.
