Airbus planes approved for long flights must replace faulty fuel valves

The US aviation regulator proposes a new rule for certain Airbus Canada airplanes. It requires replacing specific fuel transfer float valves on planes approved for extended-range twin-engine operations.

Fuel transfer float valves failing in the closed position can prevent fuel from moving between tanks. This is a problem for planes that fly long distances over water, where an engine failure could force an emergency landing far from an airport. The rule ensures these planes maintain proper fuel balance for safe operation.
