US aviation regulator orders fixes for Airbus A350 fasteners after manufacturing defect found

The US aviation regulator found that some Airbus A350 aircraft were assembled with fasteners that weren't tightened properly at critical wing joints, creating a risk of structural failure. The regulator now requires replacing those fasteners and adding protective caps to prevent the problem from recurring.

This is a routine safety fix for a specific manufacturing defect on a specific airplane model — not a structural change to how aircraft are built or certified. It matters only if you're flying an A350 that falls in this batch, or if you're tracking whether Airbus's quality control is degrading. For everyone else, this is administrative debris.
