## Discrepancy

CUSTOMER REPORTED ENG DRIVEN FUEL PUMP FAILED AT 600 FEET AGL AFTER T/O.  PILOT ACTIVATED ELEC PUMP AND SAFELY LANDED AIRPLANE.  PUMP SENT TO THIS FACILITY FOR DISASSEMBLY AND INSP.  WHEN PUMP DISASSEMBLED, 2 SMALL FLAKES OF ALUM FOUND JAMMED IN VANES OF PUMP.  THIS CAUSED PUMP TO SEIZE AND DRIVE COUPLING TO SHEAR.  VAPOR SEPARATOR OF PUMP FND TO BE SOURCE OF ALUM.  A SHARP MACHINED EDGE INSIDE HOUSING OF SEPARATOR HAD LOST MATERIAL INTO VANES OF PUMP.  CASTING OF VAPOR SEPARATOR MAY HAVE BEEN POOR QUALITY THAT ALLOWED THIS TO HAPPEN.  A POSSIBLE MEASURE TO PREVENT THIS SITUATION FROM OCCURRING WOULD BE TO ROUND THE SHARP EDGE IN VAPOR SEPARATOR DURING OVERHAUL.
