Narrative:

This was pretty much a standard 'you hear what you expect to hear' situation. I still don't know if I was cleared for a 23R ILS, which I executed until breaking out for a visual, or the 23L approach as the controller expected. I was on the bussy arrival (from the south) and was given vectors to final ending in a 'maintain 2000 until intercepting the final approach course.' I passed through the 23L final and established on the 23R final after a slight overshoot. The controller observed that I was lined up for the wrong runway and I was reclred for the 23R approach while breaking out for a visual. Landing was without incident. I have flown similar approachs to rdu before (crossing through one final for another) and was expecting to do it again. Having now had this happen to me, I plan to be much more vigilant in accepting and reading back a clearance. On the controller's part the readback should be insisted upon, and perhaps the landing runway should be mentioned in the approach clearance (I don't believe it was). For my own edification, if there is any further investigation, I would love to hear the tape.

Title: HDG TRACK DEV ON A WRONG RWY APCH.

Narrative: THIS WAS PRETTY MUCH A STANDARD 'YOU HEAR WHAT YOU EXPECT TO HEAR' SITUATION. I STILL DON'T KNOW IF I WAS CLRED FOR A 23R ILS, WHICH I EXECUTED UNTIL BREAKING OUT FOR A VISUAL, OR THE 23L APCH AS THE CTLR EXPECTED. I WAS ON THE BUSSY ARR (FROM THE S) AND WAS GIVEN VECTORS TO FINAL ENDING IN A 'MAINTAIN 2000 UNTIL INTERCEPTING THE FINAL APCH COURSE.' I PASSED THROUGH THE 23L FINAL AND ESTABLISHED ON THE 23R FINAL AFTER A SLIGHT OVERSHOOT. THE CTLR OBSERVED THAT I WAS LINED UP FOR THE WRONG RWY AND I WAS RECLRED FOR THE 23R APCH WHILE BREAKING OUT FOR A VISUAL. LNDG WAS WITHOUT INCIDENT. I HAVE FLOWN SIMILAR APCHS TO RDU BEFORE (XING THROUGH ONE FINAL FOR ANOTHER) AND WAS EXPECTING TO DO IT AGAIN. HAVING NOW HAD THIS HAPPEN TO ME, I PLAN TO BE MUCH MORE VIGILANT IN ACCEPTING AND READING BACK A CLRNC. ON THE CTLR'S PART THE READBACK SHOULD BE INSISTED UPON, AND PERHAPS THE LNDG RWY SHOULD BE MENTIONED IN THE APCH CLRNC (I DON'T BELIEVE IT WAS). FOR MY OWN EDIFICATION, IF THERE IS ANY FURTHER INVESTIGATION, I WOULD LOVE TO HEAR THE TAPE.
