Air Traffic Incident	Inter Facility Coordination Failure Operational Error

Narrative:

When I took control of the radar position, I instructed another controller to issue a heading to air carrier X that was about to be handed to me. The instructions did not correctly get passed to air carrier X. When alternate turns were issued to air carrier X, it did not take soon enough and became a conflict with cpr Y. Traffic was called to cpr Y and he reported it in sight. Visual separation was attained. The supervisor believed an error occurred and I was relieved of position. Callback conversation with reporter revealed the following information: reporter stated the types of aircraft were light transport and medium large transport. Operational error was processed because of improper coordination. Reporter yelled across the TRACON and did not use the interphone. Wrong heading was issued to air carrier X.

Original NASA ASRS Text

Title: ACR X HAD LTSS FROM CPR Y.

Narrative: WHEN I TOOK CTL OF THE RADAR POS, I INSTRUCTED ANOTHER CTLR TO ISSUE A HDG TO ACR X THAT WAS ABOUT TO BE HANDED TO ME. THE INSTRUCTIONS DID NOT CORRECTLY GET PASSED TO ACR X. WHEN ALTERNATE TURNS WERE ISSUED TO ACR X, IT DID NOT TAKE SOON ENOUGH AND BECAME A CONFLICT WITH CPR Y. TFC WAS CALLED TO CPR Y AND HE RPTED IT IN SIGHT. VISUAL SEPARATION WAS ATTAINED. THE SUPVR BELIEVED AN ERROR OCCURRED AND I WAS RELIEVED OF POS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THE TYPES OF ACFT WERE LTT AND MLG. OPERROR WAS PROCESSED BECAUSE OF IMPROPER COORD. RPTR YELLED ACROSS THE TRACON AND DID NOT USE THE INTERPHONE. WRONG HDG WAS ISSUED TO ACR X.
