## Discrepancy

RIGHT WEATHER RADAR FAILED APPROX 1 HOUR INTO FLIGHT.  LEFT RADAR FAILED WHEN SELECTED.  PERFORMED AIR TURNBACK.  REMOVED DRIED AND REINSTALLED THE WAVE GUIDE DUE TO WATER CONDENSATION.  REPLACED RADAR ANTENNA MOUNT AND RADAR CONTROL PANEL.  WEATHER RADAR CONTROL PANEL RADAR TEST CARRIED OUT OKAY.
