## Discrepancy

DURING A ROUTINE INSPECTION, THE MECHANIC FOUND A SUSPICIOUS AREA ON THE AILERON BALANCE CABLE AT THE OUTBOARD PULLEY, PN 62713-02.  THERE ARE FOUR SIMILAR PULLIES WHERE THE CABLES EXIT THE FUSELAGE AND ENTER THE WING.  THESE PULLIES WEAR ON THE CABLES AND CAUSE BROKEN STRANDS.  THESE ARE OFTEN DIFFICULT TO SEE AT FIRST AND MUST BE INSPECTED WITH A BRIGHT LIGHT AND RUBBED WITH A CLOTH RAG.  THE SAME CONDITION EXISTS WITH THE STABILATOR CABLE AND PULLEY, PN 481-612.
