TAXIING TFC INCURS ACFT DAMAGE TO 2 ACFT.

Narrative

ON ARR AT MDW WE WERE ASSIGNED TO PARK AT GATE WHICH IS ON THE SIDE OF A CONCOURSE CLOSE IN TO THE TERMINAL. I MISTAKENLY TAXIED INTO THE ALLEYWAY ON THE E SIDE OF CONCOURSE A WHERE THE ODD NUMBER GATES ARE. ONCE IN THE ALLEY THERE WAS NO PLACE TO TURN AROUND EXCEPT AT THE FAR END IN THE AREA OF GATE. I TAXIED INTO THE GATE AREA AND MADE A U-TURN AND TAXIED BACK TO GATE. IN MAKING THE TURN THE EXTREME OUTBOARD UNDER PORTION OF THE L HORIZ STABILIZER KNOCKED A STATIC WICK OFF OF THE ACFT ON GATE. THE STATIC WICK MADE A SMALL CUT IN THE UNDERSIDE OF MY STABILIZER. MY PRIMARY CONCERN IN MAKING THE TURN WAS THAT I HAD WING CLRNC AND THAT THE JET BLAST NOT ENDANGER EQUIP OR PERSONNEL. I FORGOT ABOUT TAIL GROWTH DURING THE TURN. CORRECTIVE ACTION: STRESS CONSERVATIVE TAXIING ON THE GND. WE GOT SO USED TO TAXIING IN TIGHT AREAS THAT WE BEGIN TO OVERESTIMATE OUR ABILITY WITH THE ACFT. I GUESS IF THE AREA LOOKS TIGHT AT ALL BE CONSERVATIVE AND SHUT DOWN AND ASK FOR A TUG. ANOTHER THOUGHT IS THAT YOU GET IN A TIGHT SPOT BY THINKING YOU KNOW EXACTLY WHAT YOU ARE DOING. HAVE PARKED AT GATE X MANY TIMES. I KNOW WHERE IT IS BUT FOR SOME REASON HAT DAY I GOT THINGS TURNED AROUND IN MY MIND AND WENT TO THE WRONG SIDE OF THE CONCOURSE ALL THE TIME THINKING I KNEW EXACTLY WHAT I WAS DOING. SUPPLEMENTAL INFORMATION FROM ACN 265967: AS WE TAXIED IN; I WAS COMPLETING MY COCKPIT CLEANUP PROCS; AND AS WE TURNED INTO THE PARKING AREA; I DIDN'T NOTICE ANYTHING UNUSUAL (I.E.; ODD NUMBER GATES). AIRLINES GND PERSONNEL WAS IN THE VICINITY OF GATE. I BELIEVE HE WAS LOADING ACFT Y. INITIALLY I SAW THIS INDIVIDUAL SIGNAL US TO STOP; THEN IT LOOKED AS THOUGH HE WAVED US ON TO CONTINUE. THIS MAN WAS ON THE L SIDE OF THE ACFT DURING THE TURN R. I LOST SIGHT OF HIM. UPON ARR AT THE GATE; WE WERE NOTIFIED ABOUT OUR INCIDENT WITH ACFT Y. NEITHER THE CAPT NOR I FELT THE COLLISION.
