## Discrepancy

DURING A PREFLIGHT INSPECTION, PILOT IDENTIFIED SEEPAGE FROM LT WING QUICK DRAIN.  FLUSHING DID NOT REVEAL DEBRIS THAT WOULD HAVE CAUSED LEAK, AND DID NOT ARREST LEAK.  QUICK DRAIN INSTALLED 2 YEARS PRIOR DURING FUEL CELL REPLACEMENT.  ON DISASSEMBLY, IDENTIFIED THAT THE O-RING WAS SEVERELY DISTRESSED, AND COVERED WITH CRACKS, PROVIDED THE CORRECT O-RINGS AS REPLACEMENTS.  REQUESTED TO FILE SDR, SO OWNER FILING SDR TO IDENTIFY THIS ISSUE FOR TRENDING.  NOT A FLIGHT SAFETY ISSUE - LEAK WAS MINOR.  HOWEVER, IT APPEARS THAT THE WRONG O-RINGS WERE PROVIDED WITH QUICK DRAINS BY OEM.  PART NUMBER UNKNOWN.
