## Discrepancy

RUDDER TRIM IND 5 UNITS LT WING- EICAS IND ZERO TRIM.  AFTER CLIMB ALL INDICATIONS RETURNED TO NORMAL.  VERIFIED WITH CREW THAT TRIM INDICATION WAS THE PROBLEM AND NOT A RUDDER TRIM.  IAW FIM AND TEST INDICATIONS ARE NOW NORMAL.  DUE TO PREVIOUS HISTORY DEFFERED FOR INDICATOR REPLACEMENT. ACCOMPLISHED MEL TESTS AND INSTALLED STICKER.  REPLACED RUDDER TRIM INDICATOR, TESTED OK.
