RPTED STATIC ELECTRICITY DISCHARGE TO ICSS EQUIP CAUSED GND CTL FREQ POS TO FAIL. RPTR STATES THIS HAS BEEN A CONTINUOUS PROB FOR SEVERAL YRS.

Narrative

STATIC ELECTRICITY WAS DISCHARGED INTO THE ICSS EQUIP OF THE CTL POS I WAS WORKING; CAUSING THE POS TO FAIL. I LOST ALL RADIO COMS WITH ACFT AND ALL INTERPHONE COM DUE TO THIS FAILURE. THIS HAS BEEN A CONTINUOUS PROB FOR SEVERAL YRS AND MAY CAUSE OR CONTRIBUTE TO ACCIDENTS AND INCIDENTS; IF NOT CORRECTED. AN UNSATISFACTORY CONDITION RPT WAS FILED WITH THE FAA ON JAN/XA/96; AND THERE IS NO RESOLUTION. GND CTLR FREQ AND POS FAILED CAUSING ME TO MOVE TO A POS NORMALLY USED FOR ANOTHER CTL FUNCTION. THIS SIT CONTINUES TO WORSEN CAUSING ADDITIONAL STRESS ON THE SYS USERS AND WILL COMPROMISE SAFETY SOON IF LEFT UNCHKED. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THAT THE PROB HAS NOT BEEN RESOLVED AND INDICATED THAT HE IS UNAWARE OF ANY PROPOSED REMEDY TO FIX THE PROB. RPTR STATED A DISCHARGE CAN OCCUR WHEN PASSING STRIPS FROM ONE POS TO ANOTHER CAUSING BOTH POS TO GO OTS. RPTR STATED HE CAN FEEL THE BUILDUP OF STATIC ELECTRICITY AND WILL HAVE TO KEY THE MIKE TO SEE IF THE POS/FREQ IS STILL WORKING.
