## Discrepancy

DURING A ROUTINE INSPECTION, FOUND RT AND LT INBD AFT FLAP BELLCRANKS TO HAVE EXCESSIVE PLAY IN ATTACH BRACKETS.  DURING DISASSEMBLY A TORQUE CHECK WAS DONE ON THE CENTER STUD AND FOUND TO BE UNDER THE TORQUE VALUE OF 35"LB WHICH IN TURN WAS A .2500 TURN OF THE STUD.  AFTER COMPLETE DISASSEMBLY OF BOTH INBD BELLCRANKS IT WAS FOUND THAT BOTH RT AND LT UPPER BRACKETS HAD EXCESSIVE WEAR IN THE CENTER HOLE.  REPLACED  UPPER ATTACH BRACKETS AND VERIFIED FLAP RIGGING.
