## Discrepancy

(CAN) DURING DISASSEMBLY OF A TIME EXPIRED ENGINE, THE FRONT COMPRESSOR ROTOR THIRD TO FOURTH STAGE SPACER WAS FOUND CRACKED. THERE WERE 8 CRACKS EXTENDING FROM THE TIE ROD SLEEVE HOLES TO THE INSIDE, AND THERE WAS ONE SMALL CRACK STARTING FROM THE TIE ROD SLEEVE TO THE OUTSIDE DIAMETER.
