Analysis

The pilot was practicing takeoffs and landings during a solo instructional flight at the time of the accident. She completed 7 landings without incident, and the accident approach was to be the final landing. The pilot reported that the runway was in sight, but she did not see the power lines. The airplane hit the lines and subsequently impacted the ground below the lines. The airframe sustained damage to the fuselage and left wing. According to the pilot, there were no failures or malfunctions associated with the airplane before the accident. The accident occurred about 24 minutes after sunset and about 3 minutes before the end of civil twilight. The runway was equipped with Precision Approach Path Indicator (PAPI) system. An inspection of the system after the accident revealed that it was operating normally at that time.
