A FLC IN AN ACR MD80 WAS; APPARENTLY; INITIALLY CLRED FOR A VISUAL APCH TO RWY 9L; BUT WAS LATER SWITCHED TO RWY 9R. THE FO; WHO WAS FLYING; DID NOT NOTE THE CHANGE UNTIL THE APCH CTLR AGAIN BROUGHT TO THE FLC'S ATTN.

Narrative

I WAS A CHK AIRMAN CONDUCTING IOE WITH A FO WHO WAS COMING TO THE MD80 FROM THE DC9. ON ARR IN THE ORD AREA; I WAS PNF; ATIS WAS RPTING VFR; EXPECT ILS RWY 4R; RWY 9R VISUALS TO RWY 9L. WE RAN THE DSCNT CHK AND SINCE WE WERE ARRIVING FROM THE NW; THE FO BRIEFED VISUAL RWY 9L BACKED UP BY THE ILS. HE ASKED ME TO STAY ON ORD VOR FOR DME SINCE RWY 9L HAS NO DME. SINCE CONDITIONS WERE VFR I FELT THERE WAS NO PROB WITH THIS REQUEST. WHEN WE WERE SWITCHED TO APCH THE CTLR SAID 'FLY HDG 180 DEGS; DSND AND MAINTAIN 7000 FT; VECTORS ILS RWY 9R.' I SAID; 'OK; WE'RE GOING TO RWY 9R NOW.' WE WERE VECTORED ONTO FINAL AND INTERCEPTED THE ILS USING THE FO'S CDI. AT ABOUT 10 MI THE CTLR SAID 'TURN R 120 DEGS; INTERCEPT THE RWY 9R ILS.' I WAS JUST IN THE PROCESS OF SWITCHING MY RADIO TO THE RWY 9R ILS FREQ WHEN THIS CALL WAS MADE. I ASKED THE FO IF HE KNEW WE WERE SUPPOSED TO BE ON THE RWY 9R APCH. HE SAID 'NO.' WE INTERCEPTED THE RWY 9R ILS; PICKED UP THE RWY AT ABOUT 7 MI; AND LANDED UNEVENTFULLY. FACTORS: FATIGUE -- I HAD BEEN ON DUTY OVER 10 HRS WHEN THE EVENT OCCURRED. IOE: THE FO WAS NEW TO THE MD80 AND WAS STILL GETTING ACQUAINTED WITH THE DFGS. FREQ: SATURATION -- ORD APCH IS EXTREMELY BUSY. THE CTLR WAS ISSUING INSTRUCTIONS VERY RAPIDLY WITHOUT WAITING FOR READBACKS FROM EVERY ACFT. RECOMMENDATIONS: SOP -- I AM GOING TO RECOMMEND THAT CREWS ON VECTORS TO AN APCH HAVE BOTH NAV RECEIVERS ON THE APCH NAV FREQ AS SOON AS THEY ARE ON VECTORS FOR THE APCH.
