## Discrepancy

(CAN) DURING ROUTINE INSPECTION ALUMINUM PARTICLES WERE FOUND IN THE AIRFRAME FUEL FILTER DOWNSTREAM OF THE FUEL BOOST PUMP.  RUNNING THE BOOST PUMP SHOWED THAT WHILE IT MAINTAINED OPERATING PRESSURE AN INTERMITTENT GRINDING NOISE COULD BE HEARD. DISSASEMBLY OF THE PUMP SECTION OF THE ASSEMBLY SHOWED THE TWO PIECE IMPELLER ASSEMBLY HAD BECOME DISBONDED.
