## Discrepancy

RT ENGINE FUEL PUMP SHEARED THE SHAFT AS THE ACFT WAS JUST BEGINNING TO ROLL FOR TAKEOFF.  THE CAPTAIN ABORTED THE TAKEOFF AND TAXIED THE ACFT BACK TO THE RAMP.  DISPATCHED A MECHANIC TO REPAIR THE ACFT.  CHANGED THE FUEL PUMP (PN GB317/3AU,  SN L628136LK) AND PERFORMED ALL OPS CHECKS IAW THE MM AND THE ACFT RETURNED TO BASE.
