## Narrative

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

(-23) ON JAN. 25, 2003 N732DK DEPARTED CABLE AIRPORT EN-ROUTE TO CAMARILLO. ON APPROACH TO CAMARILLO THE AIRCRAFT EXPERIENCED A COMPLETE ELECTRICAL FAILURE. PILOT HENRY ROSENTHAL DEPARTED CAMARILLO AIRSPACE AND FLEW DIRECT TO EL MONTE AIRPORT (EMT). DURING THE FLIGHT TO EMT MR. ROSENTHAL ATTEMPTED TO REGAIN ELECTRICAL POWER BUT WAS UNABLE TO RETURN THE SYSTEM TO NORMAL. N732DK LANDED AT EMT AT 1208 PST AND EXPERIENCED A RIGHT GEAR COLLAPSE. THE RIGHT GEAR COLLAPSE CAUSED SUBSTANTIAL DAMAGE TO THE PROPELLER, ENGINE, RIGHT WING, RIGHT AFT FUSELAGE, RIGHT ELEVATOR, RIGHT HORIZONTAL STABILIZER AND RIGHT AND NOSE GEAR DOORS. INITIAL INVESTIGATION REVEALED LOW BATTERY VOLTAGE, 6 DRY CELLS, INTERMITTENT BATTERY/ALTERNATOR SWITCH AND DEFECTIVE RADIO MASTER SWITCH. THE ALTERNATOR WAS REMOVED FOR EVALUATION AND TEST ALONG WITH THE REGULATOR, BATTERY AND BATTERY/ALTERNATOR SWITCH. THE TEST OF THE ALTERNATOR REVEALED A SHORTED STATOR WINDING WHICH REDUCED AMP OUTPUT TO 15 AMPS AND VOLTAGE TO 18. THE REGULATOR TESTED NORMAL AT THE OVERHAUL SHOP BUT DID FAIL ONCE DURING THE ORIGINAL FIELD TESTING. THE BATTERY/ALTERNATOR SWITCH WAS CONFIRMED INOPERATIVE AND THE BATTERY PERFORMED IAW MFG. SPECS UNDER A LOAD.

## The NTSB's investigation of this event (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
