## Discrepancy

CREW REPORTS ON APPROACH WHEN FLAP HANDLE MOVED FROM 5 TO 15, RT NEEDLE NEVER MOVED FROM 5 AND LEFT NEEDLE MOVED TO 15.  FLAPS LOCKED OUT WITH EICAS MESSAGE T/E FLAP ASYM DISPLAYED.    SAMC TEXT: PER DEBRIEF, T/E FLAP ASYM MSG WAS NOT DISPLAYED.  REPLACED FLAP POSITION INDICATOR PER MM.  TEST IS GOOD.
