## Discrepancy

BOTH LEFT AND RIGHT TAIL ROTOR CONTROL CABLES SHOW EXCESS WEAR, WHERE THEY PASS THRU THE FAIRLEADS IN THE AFT TALL CONE BULKHEAD.  CABLES HAVE BEEN WEARING IN THIS LOCATION CONSTANTLY EVERY 300 TO 400 HOURS.  SUGGEST A WIDER CONTACT SURFACE AREA AT THE FAIR LEAD TO REDUCE THE CONCENTRATION OF FRICTION.
