DEN CTLR DESCRIBED CONFUSION WITH ACFT IDENT STARTING WITH GND CTLR ENDING UP WITH ALL DEPS BEING HELD PENDING CLARIFICATION.

Narrative

ACR ABBC CALLED FOR TAXI. GND CTL THOUGHT HE HEARD ACR ABCC. THAT IS WHO HE TAXIED. HE WAS VERY BUSY WITH NUMEROUS DISTRS AT THE TIME. GND CTL PASSED THE FLT STRIP TO ME (THE LCL CTLR) FOR TKOF CLRNC. I CLRED ACR ABCC FOR TKOF. TAPE DHOWS PLT READ BACK ACR ABBC; BUT I DID NOT CATCH THAT WITH ALL THE BACKGND NOISE. JUST PRIOR TO ME SHIPPING HIM TO DEP; I NOTICED HE WAS TAGGED ACR ABBC. I QUESTIONED PLT AS TO WHO HE ACTUALLY WAS; ACR ABBC OR ACR ABCC. HE REPLIED 'YOU HAD IT RIGHT THE FIRST TIME.' SINCE HIS RTE (ACR ABBC) WOULD NOW GO IN ANOTHER CTLR'S AIRSPACE; I WENT OVER AND TRIED TO COORD A NEW HDG. HE COULDN'T DO IT BECAUSE OF HVY TFC. I THEN COORD A DIFFERENT HDG WITH DEP. I TOLD DEP THE ACR ABBC TOOK THE CLRNC FOR ACR ABCC BY MISTAKE. LATER I NOTICED DEP CHANGE THE CALL SIGN IN THE ARTS TO ACR ABCC. I THOUGHT THIS WAS WRONG AND IMMEDIATELY NOTIFIED THE SUPVR. THE DENVER TRACON SUBSEQUENTLY HAD TO STOP DEPS TO FIX THE PROB. I KNOW OF NO SEPARATION PROBS DUE TO THIS PLT TAKING A WRONG CLRNC. THERE WAS JUST CONFUSION IN TRYING TO FIX HIS MISTAKE.
