## Discrepancy

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