## Discrepancy

INSPECTION OF ELEVATOR TORQUE TUBE REVEALED LOOSE TAPER PINS ATTACHING THE TUBE TO THE COLLAR.  ENTIRE TORQUE TUBE ASSEMBLY WAS REPLACED WITH A SERVICEABLE UNIT.  THE MM PROVIDES LIMITED CRITERIA FOR RESTORING ORIGINAL SECURITY BETWEEN TUBE AND COLLAR.  PERHAPS USING A TAPERED REAMER TO REMOVE A SMALL QUANTITY OF MATERIAL COULD RETURN TUBE ASSEMBLY TO ORIGINAL SECURITY.
