## Discrepancy

ON TAKE OFF, AIRCRAFT EXPERIENCED A LOSS OF POWER AND THE PILOT ABORTED THE TAKE OFF. INSPECTION OF THE AIRCRAFT DID NOT SHOW ANY IRREGULARITIES. ENGINE HAD COMPRESSION IN ALL SIX CYLINDERS. ALL 12 SPARK PLUGS WERE CLEAN AND HAD GOOD SPARK WHEN THE MAGNETOS WERE ROTATED. THE FUEL SYSTEM WAS CLEAN WITH NO OBVIOUS BLOCKAGES. FUEL PUMP INSPECTION REPORT STATED THAT THE PUMP HAD GOOD FLOW AND PRESSURE. IT ALSO STATED THAT THERE WAS DAMAGE INTERNALLY TO THE PUMP. THE PUMP DIAPHRAGM WAS STIFF, THERE WAS DAMAGE ON THE ENDCAP, THE ROTOR, AND THE THRUST PLATE. THE DAMAGE INDICATED THAT SOMETHING HAD WENT THROUGH THE PUMP, BUT NO DEBRIS WAS FOUND IN THE PUMP.
