The NTSB's narrative final · quoted from the NTSB record

Neither the pilot nor the pilot-rated passenger provided written statements about the circumstances of the accident. Witnesses reported that the airplane was maneuvering over a freeway when it struck a series of power lines (about 45 feet above ground level) and subsequently impacted terrain. One witness reported that the airplane was maneuvering “extremely low” to the ground and appeared to be doing several low turns and dives. The witness stated that, the airplane was so low, he could see the passenger’s face through the right front window. The wings, empennage, and fuselage were substantially damaged.
