## Discrepancy

POLLUTION FOUND IN FUEL TANKS AFTER REMOVAL OF BOTH WINGS - FOLLOWING REMOVAL OF BOTH WINGS FOR REPLACEMENT OF LOWER PANELS AFTER 2C INSPECTION PERFORMED IN 2025, WE FOUND CONTAMINATION IN THE WINGS, IN THE CENTRE TANK, IN THE THREE FEEDERS’ TANKS, IN THE FILTERS AND IN THE FUEL PIPES. ANALYSES OF CONTAMINATION CONFIRMED THE PRESENCE OF ALUMINIUM POWDER, MOST PROBABLY GENERATED BY BLENDING’S IN THE CENTRE TANKS. FOLLOWING MANUFACTURER RECOMMENDATION, ALL TANKS, ALL PIPES AND ALL FILTERS NEED TO BE CLEANED. ADDITIONAL ACCESSES AND INSPECTION IN PROGRESS.
