Narrative

WITH A MINOR FLAP LEADING EDGE DISAGREEMENT INDICATION; SEVERAL CIRCUIT BREAKERS POPPED; DECISION WAS MADE TO DIVERT TO ZZZ FROM YYY. NORMAL APCH AND LNDG WAS MADE. R THRUST REVERSER INDICATED NOT DEPLOYED. AFTER CLRING RWY 27L CHIEF PURSER ANNOUNCED SMOKE ENTERING CABIN AT SEAT XX. ACRID SMELL OF ELECTRICAL BURNING; ACFT STOPPED; EVAC INITIATED. ALL PAX AND CREW RECOVERED ON GND WITH ONLY MINOR INJURIES. MAINT DETERMINED LOOM (WIRE BUNDLE) BURNING IN LOWER SECTION 41. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR IS A CAPT ON THE B767-200ER. HE SAID THAT DURING THE CLBOUT FROM YYY THEIR EICAS SCREEN STARTED INTERMITTENTLY DISPLAYING A LEADING EDGE FLAP DISAGREEMENT MESSAGE. AFTER CONSULTING WITH MAINT CTL THE CREW AND THE DISPATCHER DECIDED TO DIVERT TO ZZZ FOR A MAINT CHK. THE CAPT SAID THAT DURING THE APCH TO ZZZ THE LEADING EDGE DISAGREEMENT WAS CLRED FROM THE DISPLAY WHEN THE FLAPS WERE EXTENDED. AFTER LNDG; HOWEVER; THEY RECEIVED A CALL FROM THE LEAD CABIN ATTENDANT THAT ELECTRICAL SMOKE AND FUMES WERE COMING FROM BENEATH A SEAT THAT WAS OVER THE ELECTRICAL EQUIP COMPARTMENT. THE CAPT DECLARED AN EMER AND INITIATED AN EVAC. SEVERAL PAX RECEIVED ABRASIONS AND BRUISES AND ONE RECEIVED A BROKEN ARM. THE SMOKE AND FUMES DISSIPATED WHEN THE ACFT WAS SHUT DOWN. MAINT FOUND THAT A WIRE BUNDLE IN THE ELECTRICAL COMPARTMENT HAD SHORTED AND THE INSULATION HAD STARTED TO SMOKE. THE CAPT DID NOT KNOW IF THE WIRE INSULATION ON THE B767 IS MADE OF TEFLON OR A MORE FIRE RESISTANT MATERIAL. SUPPLEMENTAL INFO FROM ACN 390841: THE CHILLER IS LOCATED IN THE MAINT EQUIP CTR AT ZONE 119-120 ON THE R SIDE. THE CHILLER IS SURROUNDED BY WIRE BUNDLES ALONG THE TOP AND AFT SIDE OF THE UNIT. THERE IS LITTLE OR NO CLRNC BTWN THE UNIT AND SOME OF THE WIRE BUNDLES. I REMOVED THE CHILLER UNIT BY MYSELF CAREFULLY WORKING IT OUT OF ITS SUPPORT RACK. WE HAD TO MOVE THE UNIT AROUND IN ITS SUPPORT RACK IN ORDER TO ALIGN THE BOLT HOLES WITH THE MOUNT. AFTER BOLTING IN THE UNIT WE CONNECTED THE CANNON PLUG AND INSPECTED ALL ADJACENT WIRING BUNDLES NEAR THE CHILLER AND DOWN TO THE P37 ELECTRICAL LOAD PANEL. AT THIS TIME I DO NOT KNOW IF THE CHILLER ITSELF HAD AN INTERNAL FAULT OR IF POSSIBLY A WIRING PROB DEVELOPED REMOVING OR INSTALLING THE UNIT. AS I STATED BEFORE I SAW NO EVIDENCE OF ANY ELECTRICAL PROB BEFORE; DURING; OR AFTER INSTALLATION. CALLBACK CONVERSATION WITH RPTR OF ACN 390841 REVEALED THE FOLLOWING INFO: THE RPTR STATED THE WIRE BUNDLES RUN OVER AND BEHIND THE CHILLER AND IS A TERRIBLE INSTALLATION HAVING NO ROOM TO WRESTLE THE CHILLER INTO THE MOUNT AND ALIGN THE MOUNTING BOLTS. THE RPTR SAID THERE IS A LOT OF INTERFERENCE WITH THE WIRE BUNDLES WHEN THE UNIT IS INSTALLED CORRECTLY. THE RPTR STATED THE ACR IS SUPPOSED TO BE WORKING ON A CHANGE ORDER TO ISOLATE THE WIRE BUNDLES OR RUN THE BUNDLES THROUGH CONDUITS.
