Narrative

OUT OF 32500 FT FOR 33000 FT WE HEARD A LOUD BANG AND FELT A BUMP NEAR IPL. ALL INDICATIONS WERE NORMAL. CALLED DISPATCH AND MAINT AND CONTINUED TO DTW. THOUGHT IT WAS A BIRD OR AEROSOL CAN IN FORWARD CARGO BIN. DISPATCH CHKED WHAT LOAD WAS (MAIL AND BAGS). AT ABOUT 100 MI W OF ICT 2 FLT ATTENDANTS SAW SMOKE AND SMELLED ELECTRICAL BURNING. I GOT UP TO CHK FOR SMOKE AND FOUND NOTHING. I ALSO CHKED WINGS AND ENGS FROM CABIN EARLIER FOR DENTS ETC. BECAUSE OF BOTH OCCURRENCES WE DECIDED TO LAND AT ICT AND DECLARE AND EMER SO FIRE TRUCKS WOULD STAND BY AND FOLLOW US TO GATE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: AFTER THE BANG; THE A320 SHIFTED FROM L TO R AND ENTERED A 2 DEG BANK. FO SUSPECTED A BIRD STRIKE; THERE WERE NO INDICATIONS OF ENG INGESTION. FLT WAS CONTINUED AND FLC COORDINATED WITH DISPATCH TO ELIMINATE THE POSSIBILITY OF A BOMB IN CARGO. LATER DURING THE FLT; THE 3 FLT ATTENDANTS BLASTED INTO THE COCKPIT STATING THAT THEY SAW SMOKE AND NOTICED AN ELECTRICAL SMELL NEAR THE FORWARD LAVATORY. THE FLC HAD ALREADY DECIDED THAT ANY OTHER OCCURRENCE WAS GROUNDS FOR AN EMER DECLARATION; AND SO THEY DID; AND BEGAN A DSCNT WITH THE SPD BRAKES OUT; DIVERTING TO ICT. AFTER LNDG; CFR AND POLICE FOCUSSED ON FORWARD BIN; BUT THE ONLY INDICATION OF ANYTHING AWRY WAS MISSING PAINT ON THE L LEADING EDGE SLAT. COMPANY FOLLOW-UP ENSUED REGARDING DISPATCH PROCS. APPARENTLY DISPATCH LEFT THE FLT DEPT AND A320 SPECIALISTS OUT OF THE LOOP.
