## Discrepancy

DURING FLIGHT, ACFT EXPERIENCED AN ASYMMETRICAL FLAP CONDITION.  PROTECTION CIRCUIT WORKED APPROPRIATELY, BUT CREW NOTICED INTERFERENCE WITH AILERON, DECLARED AN EMERGENCY AND LANDED SAFELY.  ON INVESTIGATION, TROUBLE WAS FOUND TO BE IN THE AFT INBD BEARING.  THE "HAT SECTION" OF BEARING HAD WORN THROUGH ITS SUPPORTING RIB UNTIL IT BROKE.
