## Discrepancy

(CAN) WHEN THE TAIL ROTOR BLADES WERE REMOVED FOR SCHEDULED MX.  THE CONTROL SPIDER ASSEMBLY WAS FOUND TO BE MOVING LOOSELY ON THE SHAFT.  AFTER FURTHER INVESTIGATION IT WAS FOUND THAT THE SPHERICAL BEARING AT THE END OF THE TAIL ROTOR CONTROL TUBE WAS LOOSE.  THE CONTROL LEVER WAS LOOSE & ALSO LOOSE AT THE ATTACH POINT ON THE GEARBOX.
