## Discrepancy

(CAN) WE FOUND CORROSION ON THE BOTTOM, TCAS ANTENNA ADAPTER, AT THE SAME TIME WE REALISED THAT THE COUNTERSINK FASTENERS HOLES WERE ON THE WRONG SIDE. NEW ONE WAS ORDERED FROM THE TYPE CERTIFICATE HOLDER AND THE NEW TCAS ANTENNA ADAPTER RECEIVED HAVE THE SAME ISSUE. THE COUNTERSINKS ARE ON THE  CURVED  SIDE OF THE ADAPTER, THE ONE IN CONTACT WITH THE A/C SKIN THEY SHOULD BE ON THE  FLAT  SIDE. PART ARE IN QUARANTINE AND TREAT AS (SUP). WEE ARE IN CONTACT WITH THE TYPE CERTIFICATE OLDER.  NOTE: IPC P/N IS S92384120000, NEW P/N IS S92384127-200. (TC# 20190626011)
