## Discrepancy

ETOPS SIGNIFICANT SYS - THRUST LEVERS ALIGNED IN EPR MODE.  EPR'S MATCHED BUT IT REQUIRED 1 FULL KNOB WIDTH TO MATCH N1 & N2 AND GET THE AUDIBLE OUT-OF-PHASE SOUND TO STOP DURING CRUISE.  ENGINES POWER IS SET TO AN EPR INDICATION.  N1 & N2 NOT USED FOR PWR SETTINGS.  NO DEFECTS NOTED.  OK FOR SERVICE.
