Narrative:

This was our 6TH leg of a 7 leg day coming from sbn to cvg. Coming in from this direction (northwest) we 'expected' to get the ILS to runway 18R. The captain briefed for this approach, even though we had not yet been assigned it. I was tired and since we always fly into cvg, I don't think I paid much attention to his brief. Checking on with approach control, he gave us runway 18L ILS to expect. I'm sure I read this back to the controller, but it never really registered in my brain that we were now going to runway 18L. I 'assumed' the captain had heard this, which was wrong. I should have told him and confirmed it with him. On the final vector the controller cleared us for the ILS to runway 18L and I again read this back. I remember hearing the captain complain at what a rotten vector that the controller had us on and he was going to make a correction. The controller had us on a southeast heading and the captain then turned to the southwest. This was when it all occurred to me, but not soon enough. The captain had the frequency for runway 18R ILS set up and was still in the mind set we were going for that runway. I questioned the captain and at the same time ATC questioned us. Luckily no one else was on the ILS runway 18R approach and ATC just let us continue. I believe being tired caused our CRM to break down. The captain briefed the wrong runway and I didn't even catch this. He had the frequency for runway 18R set on his side and I had runway 18L set on my side which also should have been caught during the approach checklist.

Title: A CL65 FLC FAILS TO EXERCISE THE HIGHER LEVELS OF CRM WHEN NOT ADHERING TO APCH CTLR'S HDG FOR AN INTERCEPT OF ILS RWY 18L AT CVG, KY.

Narrative: THIS WAS OUR 6TH LEG OF A 7 LEG DAY COMING FROM SBN TO CVG. COMING IN FROM THIS DIRECTION (NW) WE 'EXPECTED' TO GET THE ILS TO RWY 18R. THE CAPT BRIEFED FOR THIS APCH, EVEN THOUGH WE HAD NOT YET BEEN ASSIGNED IT. I WAS TIRED AND SINCE WE ALWAYS FLY INTO CVG, I DON'T THINK I PAID MUCH ATTN TO HIS BRIEF. CHKING ON WITH APCH CTL, HE GAVE US RWY 18L ILS TO EXPECT. I'M SURE I READ THIS BACK TO THE CTLR, BUT IT NEVER REALLY REGISTERED IN MY BRAIN THAT WE WERE NOW GOING TO RWY 18L. I 'ASSUMED' THE CAPT HAD HEARD THIS, WHICH WAS WRONG. I SHOULD HAVE TOLD HIM AND CONFIRMED IT WITH HIM. ON THE FINAL VECTOR THE CTLR CLRED US FOR THE ILS TO RWY 18L AND I AGAIN READ THIS BACK. I REMEMBER HEARING THE CAPT COMPLAIN AT WHAT A ROTTEN VECTOR THAT THE CTLR HAD US ON AND HE WAS GOING TO MAKE A CORRECTION. THE CTLR HAD US ON A SE HDG AND THE CAPT THEN TURNED TO THE SW. THIS WAS WHEN IT ALL OCCURRED TO ME, BUT NOT SOON ENOUGH. THE CAPT HAD THE FREQ FOR RWY 18R ILS SET UP AND WAS STILL IN THE MIND SET WE WERE GOING FOR THAT RWY. I QUESTIONED THE CAPT AND AT THE SAME TIME ATC QUESTIONED US. LUCKILY NO ONE ELSE WAS ON THE ILS RWY 18R APCH AND ATC JUST LET US CONTINUE. I BELIEVE BEING TIRED CAUSED OUR CRM TO BREAK DOWN. THE CAPT BRIEFED THE WRONG RWY AND I DIDN'T EVEN CATCH THIS. HE HAD THE FREQ FOR RWY 18R SET ON HIS SIDE AND I HAD RWY 18L SET ON MY SIDE WHICH ALSO SHOULD HAVE BEEN CAUGHT DURING THE APCH CHKLIST.
