What was found
DURING A ROUTINE INSP THE LT AILERON PRIMARY CABLE (PN-0510105-360) WAS FOUND WORN AND FRAYED WHERE IT CONTACTS THE NYLON PULLEY IN THE CEILING AT FS 65.33. THE PULLEYS ROTATE FREELY, HOWEVER, CABLE DOESN'T PROVIDE ENOUGH"TRACTION" TO ROTATE IT WHEN THE AILERON CONTROL IS MOVED FROM STOP TO STOP. THIS RESULTS IN CABLE SLIPPING AGAINST PULLEY AND EVENTUALLY WEARING THROUGH STRANDS. AREA WITH BROKEN STRANDS APPEARS ONLY AS A SHINY CABLE AND THERE IS 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 THE MM OR AC 43.13.
