## Discrepancy

WEATHER RADAR FAILED JUST AFTER TAKEOFF.  FLIGHT DIVERTED DUE TO THUNDERSTORMS.  MAINTENANCE REPLACED THE RADAR ANTENNA ASSY (P/N 2041444-0401).  THE COMPONENT SHOP TESTING DID NOT REVEAL ANY FAILURES, HOWEVER THE AZIMUTH GEAR ASSY WAS FOUND WITH WATER CONTAMINATION. THE GEAR ASSY WAS DRIED AND THE ANTENNA DRIVE ASSY OPERATIONALLY CHECKED GOOD.  THE AIRCRAFT HAS FLOWN WITHOUT RADAR PROBLEMS SINCE 9 JULY.
