## Discrepancy

FLT 190 - MEX-TIJ - AIRCRAFT RETURNED TO PLATFORM AS CONSEQUENCE OF FAIL IN THE RIGHT INSTRUMENTS PANEL.  THERE WAS NO INDICATION IN FPD AND ND FIRST OFFICER SIDE, EFIS WAS SELECTED IN 1 AND THE FAIL WAS CORRECTED HOWEVER FAIL APPEARED AGAIN WHEN EFIS WAS SWAPPED, AIRCRAFT WAS CHANGED.  SYMBOL GENERATOR WAS CHECKED, AND AHRS 2 CONFIRMED FAIL UNIT WAS REPLACED, TEST OK.  (M)
