Airbus planes need more frequent checks for parts that wear out faster than expected

The US aviation regulator is proposing new rules for certain Airbus A330 planes. These rules require airlines to perform more frequent or new maintenance checks on specific parts of these aircraft.

Airlines operating these Airbus models will have to spend more on maintenance and take planes out of service more often. This change means that the original estimates for how long certain parts would last were wrong. It shifts the cost of unexpected wear and tear from passengers or the public to the airlines themselves.
