Airbus A350s need new landing gear parts after a manufacturing flaw

The US aviation regulator is ordering Airbus A350-941 airplanes to replace specific parts on their main landing gear. This is because a manufacturing process caused damage to the axles, which could make them fail.

This is a specific, mandatory fix for a known manufacturing defect. It means every affected Airbus A350-941 will need to be inspected and have parts replaced, which will add to maintenance costs and downtime for airlines. The issue stems from a high velocity oxygen-fuel stripping process, indicating a quality control problem in the supply chain for critical aircraft components.
