## Narrative

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

DESCRIPTION

AIRCAFT WAS IN CRUISE FROM WHEN A PASSENGER NOTIFIED THE CABIN CREW OF SOME SPARKS AND SMOKE COMING FROM THE SIDEWALL PANEL UNDER BIN LOCATION 13 AB. THERE WAS A NOTICEABLE BURN MARK ON THE SIDEWALL PANEL AND A SMELL OF SMOKE. THE FLIGHT DECK WAS NOTIFIED THE PILOTS INITIATED THE SMOKE DRILL AND DECIDED TO DIVERT TO ANOTHER AIRPORT.

SEVERAL CAUTION LIGHTS ILLUMINATED THAT WERE ALL RELATED TO THE #1AC ELECTRICAL SYSTEM. A MAYDAY WAS DECLARED, ATC WAS NOTIFIED AND THE DECISION TO STOP ON THE RUNWAY AND EXECUTE A RAPID DEPLANEMENT WAS MADE.

THE AIRCRAFT LANDED IN A CONTROLLED MANNER, ENGINES WERE SHUT DOWN AND ELECTRICAL POWER WAS TURNED OFF THEN THE DEPLANEMENT WAS EXECUTED IN A CONTROLLED MANNER. FIRE CREW ENTERED THE AIRCRAFT AND CARRIED OUT INITIAL INSPECTIONS FOR ANY POTENTIAL HOT SPOTS NONE WERE DETECTED, NO FIRE SUPPRESSION WAS REQUIRED.

THE AIRCRAFT WAS REMOVED FROM THE RUNWAY UNTIL SUCH TIME THAT THE TSB WAS ABLE TO INSPECT THE AIRCRAFT. THE AIRCRAFT WAS RETURNED TO MAINTENANCE FOR RECTIFICATION.

THE AC POWER CONNECTOR ON THE LH FUSE ARMPIT AREA WAS FOUND BURNT AND DAMAGED AS A RESULT OF THE ARCHING THAT OCCURRED IN THE SOCKET. BOMBARDIER SERVICE LETTER DH8-400-SL-24-016 INDICATES THAT THIS IS A KNOWN ISSUE WITH THESE CONNECTORS. THE CONNECTOR CONTAINS 3 8 GAUGE AC POWER WIRES FROM THE LH AC CIRCUIT BREAKER BOX LOCATED IN THE NACELLE. THE "P" CONNECTOR ATTACHED TO THE WIRES OUTSIDE AND INSIDE THE FUSE ARE DAMAGED AND REQUIRE REPLACEMENT. THE CONNECTOR JACK IS ALSO DAMAGED AND REQUIRES REPLACEMENT.

FURTHER INSPECTIONS ARE CURRENTLY UNDERWAY AND THE AIRCRAFT REMAINS ONN THE GROUND UNTIL REPAIRS ARE CARRIED OUT. FURTHER UPDATES WILL BE ADDED TO THIS SDR AS THE INFORMATION BECOMES AVAILABLE.

BOTH "P" SIDE CONNECTORS ON THE ENDS OF THE 8 GAUGE WIRE AND THE CONNECTOR JACK ON THE SKIN TO BE REPLACED. THE WIRE LENGTH IS GOOD ON THE OUTSIDE OF THE FUSE TO CUT BACK AND RE-TERMINATE THE REPLACEMENT CONNECTOR.

From the FAA Accident/Incident Data System.

Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
