## Discrepancy

DURING APPROACH, THE OUTBOARD TRAILING EDGE FLAPS WOULD NOT EXTEND WITH EITHER PRIMARY OR ALTERNATE SYSTEMS. DECLARED A YELLOW EMERGENCY AND FOLLOWED THE COM PROCEDURE FOR A SPLIT FLAP LANDING. AIRCRAFT LANDED WITHOUT INCIDENT.    REPLACED THE OUTBOARD TRAILING EDGE FLAP INDICATOR. OPERATIONAL CHECK GOOD.
