## Discrepancy

LT OUTER TANK HAS 280 LB WON’T HOLD FUEL WITH VLV INDICATING CLOSE.  CONFIRMED FUEL MIGRATION ON LT OUTER TANK TO INNER CELL WITH TRANSFER VLVS CLOSED.  WHILE FUELING, OUTER TANK NEVER FILLED TO MAX QUANTITY & WAS OBSERVED ON ECAM DECREASING & INNER INCREASING.  WILL REQUIRE TANK DIVE & TRANSFER VLVS REPLACEMENT.  PCN 644-0294, MEL REMAINS. NEXT MX STATION CONFIRM THIS IS NOT A BAD ACTUATOR OUTSIDE OF TANK THAT DRIVES THE FUEL TRANSFER VLV, ACTUATOR PCN IS 565-0084.
