## Discrepancy

PRIOR TO FIRST FLIGHT OF THE DAY, THE PILOT SUMPED THE FUEL FILTER.  ON FIRST START OF THE DAY PILOT DISENGAGED FUEL BOOST PUMP (ACCORDING TO PROCEDURES), THE ENGINE FLAMED OUT.  UPON INVESTIGATION, THE AIRFRAME FUEL FILTER KIT PN 350-600024 DRAIN VALVE WAS PARTIALLY STUCK OPEN, SUSPECT AIR HAD GOTTEN INTO THE FUEL SYSTEM.  UPON FURTHER INVESTIGATION FUND DEBRIS IN THE FUEL FILTER BOWL.  PROCEDURES FOR INSPECTION TO BE PERFORMED BEFORE FIRST FLIGHT ARE IN THE MAINTENANCE ICA DOCUMENT ICA-ECL-129, BUT THEY ARE NOT INCORPORATED INTO THE FLIGHT MANUAL SUPPLEMENT, THEREFORE THE PILOT WAS UNAWARE OF THE PROCEDURES TO BE INCLUDED IN BFF INSPECTIONS THAT ARE REQUIRED.
