## Analysis

THE ACFT COLLIDED WITH A TREE AND BROKE THE NOSE LANDING GEAR DURING AN EMERGENCY LANDING AFTER ELECTRICAL FAILURE. AFTER THE FAILURE, USING MATCHES AND A FLASHLIGHT, THE PLT TRIED TO LAND BUT COULD NOT FIND THE ARPT. THE WEATHER WAS DETERIORATING SO WHEN A FIELD THAT SEEMED SUITABLE FOR LANDING APPEARED THE CREW DECIDED TO LAND. THE ACFT HAD ONLY BEENOPERATED ABOUT 22 HOURS SINCE THE ELECTRICAL SYSTEM HAD BEEN REPAIRED AFTER A CHARGING PROBLEM WAS REPORTED. AFTER THE ACCIDENT THE ALTERNATOR AND REGULATOR WERE TESTED AND FOUND DEFECTIVE. VISUAL INSPECTION OF THE ALTERNATOR SHOWED THAT BOTH BRUSH SLIP RINGS WERE GOUGED AND GROOVED. ONE OF THE TWO WIRES ATTACHED TO THE SLIP RING TERMINAL WAS NOT SOLDERED AS IT SHOULD HAVE BEEN. THIS WIRE WAS LOSELY BENT AROUND THE TERMINAL.
