## Discrepancy

(CAN) DURING REMOVAL OF TORQUE TUBES, END RIBS FOUND TO BE CRACKED AT RIB/SKIN TO TORQUE ATTACHMENT POINTS AND FORWARD CORNERS OF END RIB.  SKIN/RIB DIMPLES THOUGHT TO BE CRACKED DUE TO OVER COUNTERSINKING TORQUE TUBE ASSEMBLY ATTACH POINTS.  TORQUE TUBES ONLY COME WITH PILOT HOLES.
