## Discrepancy

FLIGHT DIVERTED DUE TO WX RADAR FAILURE. CREW REPORTED WX RADAR INOP. DOES NOT PAINT AND GREEN ARC ON DISPLAY.  ALSO, NO GROUND RETURNS.  ( THE GREEN ARC IS A FLAT PLATE ANTENNA ANOMALY THAT DOES NOT AFFECT WX RADAR PERFORMANCE.)  MAINTENANCE REPLACED THE WX RADAR CONTROL PANEL AND THE WX RADAR SCANNER.  THERE HAVE BEEN NO RECURRING PROBLEMS INVOLVING WX RADAR PERFORMANCE.
