Reporter at sct claims that occasionally when handing off a radar data tag to poc tower, critical data is lost to both sct and poc. Reporter said the problem began when the ARTS IIIE was installed approximately one and one half yrs ago.

Narrative:
While vectoring aircraft X on a base leg to intercept the brackett ILS northbound, data tag converted to a '0K.' all aircraft identify, aircraft type, speed, and altitude was lost at a crucial point of the approach. Data tag had been handed off to brackett ATCT when it disappeared. Callback conversation with reporter revealed the following information: reporter added that since the installation of the ARTS IIIE approximately 1 1/2 yrs ago, problems making mechanical handoffs to poc have occurred. Controllers have been filing ucr's without any improvement shown. Reporter claims that management has told them that as soon as the LOA with poc is updated the problem will be fixed.

Narrative: WHILE VECTORING ACFT X ON A BASE LEG TO INTERCEPT THE BRACKETT ILS NBOUND, DATA TAG CONVERTED TO A '0K.' ALL ACFT IDENT, ACFT TYPE, SPD, AND ALT WAS LOST AT A CRUCIAL POINT OF THE APCH. DATA TAG HAD BEEN HANDED OFF TO BRACKETT ATCT WHEN IT DISAPPEARED. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR ADDED THAT SINCE THE INSTALLATION OF THE ARTS IIIE APPROX 1 1/2 YRS AGO, PROBS MAKING MECHANICAL HDOFS TO POC HAVE OCCURRED. CTLRS HAVE BEEN FILING UCR'S WITHOUT ANY IMPROVEMENT SHOWN. RPTR CLAIMS THAT MGMNT HAS TOLD THEM THAT AS SOON AS THE LOA WITH POC IS UPDATED THE PROB WILL BE FIXED.
