Narrative:

I was the PF; we were transitioning through rough WX and discussing an alternate route around the WX. ATC (center) switched us over to cincy approach. They assigned us runway 36R and 10 degrees to the left (we were 17 mi from snppr). With the WX; rain; turbulence; I believe that the 10 degrees to the left was misheard as runway 36L; we continued in and as approach gave us final vectors and cleared us for runway 36R approach we realized that someone had made a mistake. We queried ATC; they gave us climbing vectors to the east; with vectors for runway 36R. We briefed each approach to air carrier standards. We returned to land with no other issues. Supplemental information from acn 750641: just after checking in with approach in cvg we requested vectors to the left of course for WX. I loaded runway 36L in the FMS and briefed approach plate and switched to final controller. We did not confirm the runway assignment. We were vectored to runway 36R. We were not set up for runway 36R and notified the controller we had been assigned the left side. He vectored us to the right and back around for runway 36R outside of snppr. We had re-setup for runway 36R and briefed as appropriate. I spoke with ATC after arrival into cvg and was told our initial assignment was runway 36R and left deviations after the assignment was given were issued. The controller thought that may have caused some confusion. However; he added that there were no conflicts. I also believe we should have confirmed our assignment with the final controller upon check-on. Usually they do but they were busy and I did not check.

Title: A CRJ 200 CREW PROGRAMMED THE FMS FOR CVG 36L AND MISSED ATC'S RWY 36R ASSIGNMENT. AFTER THE CREW ASKED FOR WX DEVIATIONS TO RWY 36L THEY WERE VECTORED FOR ANOTHER APCH AND 36R FMS SETUP.

Narrative: I WAS THE PF; WE WERE TRANSITIONING THROUGH ROUGH WX AND DISCUSSING AN ALTERNATE RTE AROUND THE WX. ATC (CTR) SWITCHED US OVER TO CINCY APCH. THEY ASSIGNED US RWY 36R AND 10 DEGS TO THE L (WE WERE 17 MI FROM SNPPR). WITH THE WX; RAIN; TURB; I BELIEVE THAT THE 10 DEGS TO THE L WAS MISHEARD AS RWY 36L; WE CONTINUED IN AND AS APCH GAVE US FINAL VECTORS AND CLRED US FOR RWY 36R APCH WE REALIZED THAT SOMEONE HAD MADE A MISTAKE. WE QUERIED ATC; THEY GAVE US CLBING VECTORS TO THE E; WITH VECTORS FOR RWY 36R. WE BRIEFED EACH APCH TO ACR STANDARDS. WE RETURNED TO LAND WITH NO OTHER ISSUES. SUPPLEMENTAL INFO FROM ACN 750641: JUST AFTER CHKING IN WITH APCH IN CVG WE REQUESTED VECTORS TO THE L OF COURSE FOR WX. I LOADED RWY 36L IN THE FMS AND BRIEFED APCH PLATE AND SWITCHED TO FINAL CTLR. WE DID NOT CONFIRM THE RWY ASSIGNMENT. WE WERE VECTORED TO RWY 36R. WE WERE NOT SET UP FOR RWY 36R AND NOTIFIED THE CTLR WE HAD BEEN ASSIGNED THE L SIDE. HE VECTORED US TO THE R AND BACK AROUND FOR RWY 36R OUTSIDE OF SNPPR. WE HAD RE-SETUP FOR RWY 36R AND BRIEFED AS APPROPRIATE. I SPOKE WITH ATC AFTER ARR INTO CVG AND WAS TOLD OUR INITIAL ASSIGNMENT WAS RWY 36R AND L DEVS AFTER THE ASSIGNMENT WAS GIVEN WERE ISSUED. THE CTLR THOUGHT THAT MAY HAVE CAUSED SOME CONFUSION. HOWEVER; HE ADDED THAT THERE WERE NO CONFLICTS. I ALSO BELIEVE WE SHOULD HAVE CONFIRMED OUR ASSIGNMENT WITH THE FINAL CTLR UPON CHK-ON. USUALLY THEY DO BUT THEY WERE BUSY AND I DID NOT CHK.
