## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

DURING CRUISE FLIGHT ON DECEMBER 27, 2010, THE AIRCRAFT LOST ELECTRICAL POWER. AN EMERGENCY WAS DECLARED DUE TO INABILITY TO VERIFY THAT LANDING GEAR WAS DOWN-AND-LOCKED FOLLOWING EMERGENCY PROCEDURES USED TO EXTEND THEM. COMMUNICATION WAS MADE WITH ATC BY WAY OF A HANDHELD VHF RADIO. AN UNEVENTFUL LANDING WAS PERFORMED WITH EMERGENCY EQUIPMENT ON-SCENE. FOLLOW-ON INVESTIGATION YIELDED THAT THE FIELD WIRE TERMINAL WHICH FED THE ALTERNATOR FROM THE VOLTAGE REGULATOR HAD BROKEN AT THE VOLTAGE REGULATOR TERMINATION POINT. THE ALTERNATOR HAD BEEN INSTALLED IN MARCH OF 2002 (>11 YEARS PRIOR) AND THE 12 INCH FEEDER WIRE MAY HAVE BROKEN DUE TO MANY YEARS OF ENGINE INDUCED VIBRATION. WITHOUT THIS FIELD INPUT, THE ALTERNATOR FAILED TO CHARGE THE BATTERY AND EVENTUALLY ALL ELECTRICAL SYSTEMS FAILED.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
