Analysis

The plt said that during a night cross country flight, an electrical failure occurred. After trying to find a nearby airport, and circling for about 15 minutes, a precautionary ldg was attempted, without flaps or lights due to the electrical failure, on a road which resulted in a nose over. Post accident investigation revealed the airport beacon was inoperable and brightly lighted construction adjacent the airport made it difficult to locate. Loose connections were found on the battery terminal and the alternator.
