## Discrepancy

DURING HEAVY MAINTENANCE, FOUND THE TAIL ROTOR FLEXBALL CABLE OUTER SHEATH AT THE AFT END TO BE BROKEN AND SEPARATED FROM THE CRIMPING SLEEVE APPROXIMATELY 1/4".  IF LEFT UNDISCOVERED FOR MUCH LONGER THERE WAS A RISK OF MECHANICAL BINDING OR INTRODUCTION OF FOREIGN DEBRIS / WATER WHICH COULD ALSO CAUSE BINDING.
