Incident Overview
A pilot and a mechanic were ferrying an airplane back to its base after replacing the starter, battery solenoids, and battery. The preflight run-up revealed no anomalies, and the ammeter indicated a full charge. Approximately 30 minutes after departure, the interior lighting began to dim and the airplane's electrical system failed completely. Unable to locate the destination airport or an alternate, and concerned about fuel exhaustion, the pilot elected to conduct a precautionary landing in a soft, dirt field. During the landing, the airplane nosed over.
Post-Accident Examination
Following the accident, the Federal Aviation Administration (FAA) examined the airplane's electrical system. The inspection revealed that the alternator had failed internally and the battery was completely discharged. Additionally, the FAA inspector observed that the alternator's 60-amp circuit breaker was in the "popped" position.
Pilot Experience
The pilot reported approximately 5 hours of total night flying experience, with about 1 hour of that occurring within the preceding 90 days.
