The NTSB's narrative final · quoted from the NTSB record
Witnesses observed the weight-shift-control aircraft flying at a low altitude down the river, and the solo student pilot waving to people on the ground. As the airplane approached a set of transmission wires about 100 feet above the ground, the pilot banked the airplane sharply right to avoid them. One witness said the bank angle was more than 90 degrees. It is likely that the pilot was unable to maintain control of the airplane during this maneuver as it lost altitude. The airplane subsequently struck another set of wires about 30 feet above the ground and cartwheeled to the ground.
