MLG BEING GUIDED INTO PARKING SPACE WITH GUIDEMAN AND WING WALKERS. WING TIP MAINT STAND. DAMAGE TO WING TIP.

Narrative

WHILE FOLLOWING 'LEAD-IN LINE' AND GUIDEMAN INTO GATE X AT ORD; ABOUT 15 FT FROM THE GATE I FELT THE ACFT VIBRATE AND IMMEDIATELY STOPPED; AFTER WHICH THE GUIDEMAN GAVE ME THE STOP SIGNAL. I REQUESTED THE GUIDEMAN ESTABLISH INTERPHONE COM AND ASKED HIM WHAT HAPPENED. HE SAID THE L WING TIP HIT A MAINT PLATFORM AND SAID THAT HE DID HAVE WING WALKERS IN POS. I INFORMED RAMP CTL I WOULD NOT MOVE THE ACFT AND TALKED TO MAINT ON THE INTERPHONE. THEY SAID THEY INSPECTED THE DAMAGE AND WERE GOING TO HOOK UP A TOW-BAR. THE ACFT WAS PUSHED REWARD AND THEN PULLED FORWARD TO THE GATE. I WAS NOT ABLE TO LOCATE THE GUIDEMAN AFTER THIS POINT TO FIND OUT EXACTLY WHAT HAPPENED. I CONTACTED THE ORD BASE MGR AND INFORMED HIM OF THE INCIDENT. THE ACFT WAS TAKEN OTS AND AN 'IRREGULAR RPT' FILED WITH THE BASE MGR AT LAX. AT THIS TIME I HAVE NO DEFINITE INFO IN HELPING TO DETERMINE THE EXACT CAUSE OF THE INCIDENT; AS I HAVEN'T BEEN IN CONTACT WITH THE MAINT PERSONNEL; NOR THE GUIDEMAN THAT WERE PARKING THE ACFT.
