## Discrepancy

TECH WAS IN TAILCONE AREA AND NOTICED METAL SHAVINGS UNDER RUDDER SERVO ASSY.  INVESTIGATION REVEALED THAT THE SERVO DRUM  CABLE WAS CUTTING THROUGH THE DRUM GROOVES ARE TO SEVERE SIDE LOADING ON THE CABLE.  SUSPECT THAT THE SEVERE SIDE LOAD CONDITION RESULTED FROM IMPROPER PLACEMENT OF SERVO CABLE TO MAIN SYSTEM CABLE CLAMP.  ROTATION OF THE CLAMP ON THE MAIN RUDDER SYSTEM CABLE INDUCED THE SIDE LOAD.  THIS AC WAS NOT IN FOR AN INSPECTION AND THE TECH FOUND THIS CONDITION BY CHANCE.  (K)
