## Discrepancy

(CAN) ENGINE WAS REMOVED FROM THE ACFT DUE TO NO N2 ROTATION.  UPON ENGINE DISASSEMBLY, FOUND A BROKEN SLAB-HEAD MACHINE BOLTS ON THE HP COMPRESSOR WHEEL STAGE 1 ASSY.  THE BROKEN PART GOT TRAPPED BETWEEN THE HP COMPRESSOR STAGE 1 WHEEL AND FRONT SUMP HOUSING, PREVENTING THE COMPRESSOR ROTOR FROM ROTATING FREELY, NO ROTATION.
