Air Traffic Incident | Operational Error |
Narrative:
The incident of a near miss or operational error occurred on the dates and times above were caused while I was working the tower position at O'hare tower. During a period of moderate traffic (departing 9L and 32L) I mistakenly gave a heading to the incorrect company airlines flight. By giving control instructions to the incorrect flight, I caused a flight (air carrier X) to pass over an aircraft on the 9R final approach course. The problem was discovered when the pilot questioned the assigned heading. I quickly took evasive action and turned air carrier X from further conflicts. What contributed to the incorrect call sign was a report from another controller of a missed approach heading for my airspace. I was in the process of sending air carrier X to departure control when the other controller yelled in the cabin attendant 'going around 4 right.' in the midst of my transmission to ship air carrier X to departure, I instead turned him to a heading 090 (he was already on a 330) thinking he was the company flight also airborne off of 9L. (The one I really needed to talk to about the miss approach). To prevent a recurrence I would suggest that to myself I pause to consider the missed approach and not react too quickly especially if not necessary. Also possibly more standardization of missed approachs at O'hare.

Title: CTLR VECTORS WRONG ACFT AFTER DEP AND CONFLICTS WITH AN ARR ACR RESULTING IN LTSS.
Narrative: THE INCIDENT OF A NEAR MISS OR OPERATIONAL ERROR OCCURRED ON THE DATES AND TIMES ABOVE WERE CAUSED WHILE I WAS WORKING THE TWR POS AT O'HARE TWR. DURING A PERIOD OF MODERATE TFC (DEPARTING 9L AND 32L) I MISTAKENLY GAVE A HDG TO THE INCORRECT COMPANY AIRLINES FLT. BY GIVING CTL INSTRUCTIONS TO THE INCORRECT FLT, I CAUSED A FLT (ACR X) TO PASS OVER AN ACFT ON THE 9R FINAL APCH COURSE. THE PROBLEM WAS DISCOVERED WHEN THE PLT QUESTIONED THE ASSIGNED HDG. I QUICKLY TOOK EVASIVE ACTION AND TURNED ACR X FROM FURTHER CONFLICTS. WHAT CONTRIBUTED TO THE INCORRECT CALL SIGN WAS A RPT FROM ANOTHER CTLR OF A MISSED APCH HDG FOR MY AIRSPACE. I WAS IN THE PROCESS OF SENDING ACR X TO DEP CTL WHEN THE OTHER CTLR YELLED IN THE CAB 'GOING AROUND 4 R.' IN THE MIDST OF MY XMISSION TO SHIP ACR X TO DEP, I INSTEAD TURNED HIM TO A HDG 090 (HE WAS ALREADY ON A 330) THINKING HE WAS THE COMPANY FLT ALSO AIRBORNE OFF OF 9L. (THE ONE I REALLY NEEDED TO TALK TO ABOUT THE MISS APCH). TO PREVENT A RECURRENCE I WOULD SUGGEST THAT TO MYSELF I PAUSE TO CONSIDER THE MISSED APCH AND NOT REACT TOO QUICKLY ESPECIALLY IF NOT NECESSARY. ALSO POSSIBLY MORE STANDARDIZATION OF MISSED APCHS AT O'HARE.
