## Discrepancy

FLAP SPLIT INDICATED BY .5 NEEDLE WIDTH.  NO ROLL TENDENCY.  EACH TIME LOOKS LIKE RIGHT NEEDLE LAGGED BY .5 NEEDLE WIDTH AND THEN CATCHES UP WITH LEFT NEEDLE.  CYCLED FLAP POSITION INDICATOR C-B AND DID GET NEEDLES TO PAIR UP.  SUSPECT POSITION INDICATOR FAULTY.   REPLACED FLAP POSITION INDICATOR ACCOMPLISHED OPERATIONAL CHECK OF FLAP POSITION INDICATOR. INDICATOR OPERATES NORMAL.  AC OK FOR SERVICE.
