## Discrepancy

AIRCRAFT NOT GROUNDED: PILOT REPORTED THAT THREE HOURS INTO THE FLIGHT, AMBER VOR 2 FAILURE FLAG APPEARED ON BOTH CA AND FO NAV DISPLAYS.  NOTE: WE HAD A GOOD VOR STATION DIALED IN SJN ONLY 35 MILES AWAY 112.3 MHZ VOR 1 RECEIVED VALID SIGNAL BUT VOR 2 DIDNT OR COULDNT RECEIVE A SIGNAL. SAME RESULT A FEW MINUTES LATER WITH PXR 115.6 MHZ SEVENTY MILES AWAY.  NOTE: NO CHANGE TO AMBER FAILURE FLAG (CONTINUED FROM PREVIOUS  BLOCK) WITH THE VHF NAV SWITCH ON OVHD PANEL IN BOTH ON 1 OR BOTH ON 2. MAINTENANCE ACCOMPLISHED VOR FIM TASK 34-51-00. NO FAULTS NOTED. NO HISTORY. OK FOR SERVICE.
