## Discrepancy

DURING A ROUTINE INSP, THIS CABLE LOCATED IN THE CTR CEILING, AT STA 65.33, WAS FOUND BADLY WORN WHERE IT CONTACTS ONE OF THE 3 PULLEYS. THE PULLEY FREELY ROTATES HOWEVER THERE IS NOT ENOUGH "TRACTION" FROM THE CABLE TO ROTATE THE PULLEY DURING NORMAL OPERATION. THIS CAUSES THE CABLE TO SLIDE ACROSS THE PULLEY WHICH CREATES A WEAR POINT. THE CABLE APPEARS SHINY, BUT IF VIEWED WITH A STRONG MAGNIFIER, MANY INDIVIDUAL STRANDS CAN BE SEEN BROKEN.
