## Discrepancy

WHEN FLAPS WERE POSITIONED TO FLAPS 2, THE LEFT AND RIGHT OUTBOARD SHOWED SLIGHT ASYMMETRY (ABOUT 1 NEEDLE WIDTH) RAN CHECKLIST AND LOWERED FLAPS WITH ALTERNATE FLAP SWITCHES.  FLAPS LOWERED TO 30 ON BOTH OUTBOARD, BUT INBOARD NOW SHOWED A SLIGHT SPLIT(ABOUT 5).  HOWEVER, THE NEEDLE EVENTUALLY VIBRATED (OR FLICKERED) TO NORMAL(30,30).  REPLACED OUTBOARD  FLAP INDICATOR.  RAN FLAPS.  INDICATION AND FLAPS CHECKED   NORMAL.
