What was found
AILERONS WERE BEING MOVED THROUGH THEIR RANGE DURING STATIC TRAINING AND IT WAS NOTED THAT THEY WERE STIFF AND AN ODD SOUND WAS REPORTED. UPON INVESTIGATION A TECHNICIAN FOUND THAT THE ROUTING THROUGH THE CENTER WING BOX PULLEY AT STATION 442 WAS INCORRECT, LEADING TO FRAYING OF THE AILERON CONTROL CABLE, CAUSED BY RUBBING AGAINST THE PULLEY CABLE GUIDE/RETAINING PIN. THE AIRCRAFT WAS ALREADY REMOVED FROM SERVICE FOR ANOTHER DISCREPANCY AND REMAINS SO UNTIL DISCREPANCIES ARE CORRECTED.
