## Discrepancy

(CAN) DURING SCHEDULED MAINTENANCE CRACKS WERE DISCOVERED EMANATING FROM THE TAPER PIN HOLES ON THE ELEVATOR TORQUE TUBE MIDDLE FITTINGS (BOTH SIDES). (ONE CRACK PER FITTING - TWO FITTING TOTAL).  TAPER PINS WERE ALSO FOUND TO BEYOND THE .060 INCH MAX PROTRUSION.  PINS MUST HAVE BEEN HAMMERED ON IN THE PAST TO TIGHTEN THEM UP IN THE FITTING/TORQUE TUBE CAUSING HIGHER THAN NORMAL STRESS IN FITTING HOLE.  MAINTENANCE MANUAL STATED NOT TO HAMMER BUT TO TORQUE NUT ONLY.  (X)
