What was found
DURING INSP RT AILERON PRIMARY CABLE (PN-0510105-360) WAS FOUND WORN AND FRAYED WHERE IT CONTACTS NYLON PULLEY IN THE CEILING AT FS 65.33. PULLEYS ROTATE FREELY, HOWEVER, CABLE DOESN'T PROVIDE ENOUGH "TRACTION" TO ROTATE IT WHEN AILERON CONTROL IS MOVED FROM STOP TO STOP. THIS RESULTS IN THE CABLE SLIPPING AGAINST PULLEY AND EVENTUALLY WEARING THROUGH THE STRANDS. AREA WITH BROKEN STRANDS APPEARS ONLY AS A SHINY CABLE AND THERE ARE NO OBVIOUS BROKEN STRANDS. IT MUST BE VIEWED WITH A POWERFUL MAGNIFYING GLASS AND BRIGHT LIGHT. IN MANY CASES THE NR OF BROKEN STRANDS FAR EXCEED THE AMOUNT SHOWN IN EITHER MM OR AC 43.13.
