Read the full NTSB narrative

THE ACFT HAD A COMPLETE ELECTRICAL FAILURE & THE PLT MADE AN EMERGENCY LANDING AT LANSING. THE PLT WAS UNABLE TO LOWER THE FLAP, & AFTER ENCOUNTERING GROUND FOG LANDED LONG, BOUNCED, & GROUND LOOPED TO AVOID RUNNING OFF THE END OF THE RWY.INVEST OF THE ELECT SYSTEM REVEALED THAT AN UNIDENTIFIABLE NOISE FILTER HAD BEEN INSTALLED IN THE LINE OF THE OUTPUT SIDE OF THE ALTERNATOR. TESTING REVEALED THAT THE NOISE FILTER DEVELOPED VOLTAGE SPIKES THAT COULD INCREASE LINE VOLTAGEMOMENTARILY TO 16 VOLTS. THE OVERVOLTAGE SENSOR WAS INOPERATIVE. THE SENSOR WAS PROBABLY TRIPPED BY EXCESSIVE SPIKING ON THE LINE VOLTAGE WHICH WOULD TURN OFF THE ALTERNATOR SYSTEM ILLUMINATING THE OVERVOLTAGE WARNING LIGHT. HOWEVER, THE BULB WAS FOUND BURNED OUT. THIS CONDITION CAN USUALLY BE CORRECTED BY RECYCLING THE MASTER SWITCH TO RESUME NORMAL ALTERNATING CHARGING.
