Aircraft Accident/Incident Report

Anchorage, Alaska 99502
Sunday, December 13, 1992 10:45 AST

NTSB Narrative Summary Released at Completion of Accident

DURING THE TAKEOFF CLIMB THE PILOT SMELLED WHAT HE THOUGHT WAS BURNING ELECTRICAL WIRES, AND THE COCKPIT FILLED WITH SMOKE. THE ENGINE LOST ALL POWER ALMOST IMMEDIATELY. THE OFF AIRPORT FORCED LANDING ON THE MUD FLATS RESULTED IN SUBSTANTIAL DAMAGE TO THE AIRPLANE WHEN IT NOSED OVER. EXAMINATION FOUND THAT THE VOLTAGE REGULATOR HAD SHORTED OUT. THIS CAUSED A BRIEF LOCALIZED FIRE WHICH BURNED AND SHORTED OUT THE MAGNETO 'P' LEADS, CAUSING THE ENGINE TO STOP RUNNING.

NTSB Probable Cause Narrative

THE TOTAL LOSS OF ENGINE POWER DUE TO A SHORT IN THE VOLTAGE REGULATOR, AND THE LACK OF SUITABLE TERRAIN FOR THE PILOT TO MAKE THE FORCED LANDING ON.
