Airbus planes must replace engine fuel valves after multiple in-flight failures

US aviation regulators are ordering Airbus to replace engine fuel valves on all BD-500-1A10 and BD-500-1A11 airplanes. This is because multiple valves failed in flight, causing fuel imbalances.

This rule means airlines operating these specific Airbus models must now perform mandatory, repetitive maintenance. It directly addresses a safety issue that could lead to dangerous fuel imbalances during flight. The cost of these replacements will be borne by the airlines, not the manufacturer, for planes already in service.
