Narrative:

Flight was air carrier flight XXX designated as a 'lifeguard' flight due to transportation of human organs. Approaching chicago from madison, wi, we were told to fly a heading for runway 9L at O'hare by the second approach controller (apparently to expedite the arrival due to the 'lifeguard' designation). The normal landing runway at that time was runway 9R. The approach to runway 9L was briefed and set up. The final instructions were to maintain 3500 ft until established on the localizer, cleared the approach (not sure if they actually said 'ILS runway 9R'), maintain 17000 ft until deana (FAF for runway 9R), tower at deana 120.75.' we did not catch the fact that we were cleared for a different approach than the approach controller had previously said. We are also not sure if we talked to 2 or 3 approach controllers. O'hare tower sent us around just inside of 'lanse' after 'deana' was reported and then corrected 'lanse' is the FAF for runway 9L. We were IMC at the go around initiation and approximately 40 NM from the runway and approximately 1500 ft AGL. Go around and approach to runway 4R were uneventful. Supplemental information from acn 375731: we were switched to another approach controller and subsequently cleared for the ILS and told to contact tower approaching the FAF. We intercepted the runway 9L ILS and when we contacted tower they informed us they were not expecting us, that we should be on runway 9R, and to execute climb out. The missed approach was uneventful and we came back for a landing. We were IMC. Without listening to the tapes we cannot be sure but I believe we were fixated (after being told to expect runway 9L) on runway 9L and intercepted that final by mistake. Although due to confusion between the controllers on approach and tower we might have been told just to intercept the ILS, which we thought was to runway 9L. Either way there was uncertainty and we should have clarified it.

Title: AN MLG DESIGNATED AS A LIFEGUARD FLT, MAKES A FAST, HURRIED APCH INTO ORD, IL. THE HURRIED APCH RESULTS IN A GAR AS THE FIRST APCH IS TO THE WRONG RWY.

Narrative: FLT WAS ACR FLT XXX DESIGNATED AS A 'LIFEGUARD' FLT DUE TO TRANSPORTATION OF HUMAN ORGANS. APCHING CHICAGO FROM MADISON, WI, WE WERE TOLD TO FLY A HEADING FOR RWY 9L AT O'HARE BY THE SECOND APCH CTLR (APPARENTLY TO EXPEDITE THE ARR DUE TO THE 'LIFEGUARD' DESIGNATION). THE NORMAL LNDG RWY AT THAT TIME WAS RWY 9R. THE APCH TO RWY 9L WAS BRIEFED AND SET UP. THE FINAL INSTRUCTIONS WERE TO MAINTAIN 3500 FT UNTIL ESTABLISHED ON THE LOC, CLRED THE APCH (NOT SURE IF THEY ACTUALLY SAID 'ILS RWY 9R'), MAINTAIN 17000 FT UNTIL DEANA (FAF FOR RWY 9R), TWR AT DEANA 120.75.' WE DID NOT CATCH THE FACT THAT WE WERE CLRED FOR A DIFFERENT APCH THAN THE APCH CTLR HAD PREVIOUSLY SAID. WE ARE ALSO NOT SURE IF WE TALKED TO 2 OR 3 APCH CTLRS. O'HARE TWR SENT US AROUND JUST INSIDE OF 'LANSE' AFTER 'DEANA' WAS RPTED AND THEN CORRECTED 'LANSE' IS THE FAF FOR RWY 9L. WE WERE IMC AT THE GAR INITIATION AND APPROX 40 NM FROM THE RWY AND APPROX 1500 FT AGL. GAR AND APCH TO RWY 4R WERE UNEVENTFUL. SUPPLEMENTAL INFO FROM ACN 375731: WE WERE SWITCHED TO ANOTHER APCH CTLR AND SUBSEQUENTLY CLRED FOR THE ILS AND TOLD TO CONTACT TWR APCHING THE FAF. WE INTERCEPTED THE RWY 9L ILS AND WHEN WE CONTACTED TWR THEY INFORMED US THEY WERE NOT EXPECTING US, THAT WE SHOULD BE ON RWY 9R, AND TO EXECUTE CLBOUT. THE MISSED APCH WAS UNEVENTFUL AND WE CAME BACK FOR A LNDG. WE WERE IMC. WITHOUT LISTENING TO THE TAPES WE CANNOT BE SURE BUT I BELIEVE WE WERE FIXATED (AFTER BEING TOLD TO EXPECT RWY 9L) ON RWY 9L AND INTERCEPTED THAT FINAL BY MISTAKE. ALTHOUGH DUE TO CONFUSION BTWN THE CTLRS ON APCH AND TWR WE MIGHT HAVE BEEN TOLD JUST TO INTERCEPT THE ILS, WHICH WE THOUGHT WAS TO RWY 9L. EITHER WAY THERE WAS UNCERTAINTY AND WE SHOULD HAVE CLARIFIED IT.
