| Investigating agency: | NTSB |
| Confidence Rating: |  Accident investigation report completed and information captured |
The student pilot was completing a solo cross-country flight when he noticed the low voltage warning light illuminate; however, since the voltmeter continued to indicate about 28 volts (v), he continued the flight to the destination airport and completed a touch-and-go landing before proceeding back to the departure airport. The pilot later stated that he was 'not confident that he completely understood how an electrical system failure may affect the aircraft.' As the pilot attempted to lower the flaps before landing, the airplane experienced a complete loss of electrical power, and the flaps did not extend.
The student pilot conducted a no-flap landing to the 3,600-ft-long runway, during which the airplane bounced multiple times and continued off the end of the runway and over a retaining wall, resulting in substantial damage. The pilot reported that he had not received training in no-flap landings.
Examination of the alternator revealed no anomalies that would have precluded normal operation. Some wiring associated with the alternator displayed areas of broken insulation and exposed wire; however, it could not be determined if this was due to preaccident chafing or the result of impact damage. Based on the available information, the reason for the loss of electrical power could not be determined.
Probable Cause: A total loss of electrical power for reasons that could not be determined, and the student pilot's subsequent runway overrun during a no-flap landing.
