Airbus A350s must replace flight control parts before they fail

The US aviation regulator proposes a new rule for all Airbus A350 airplanes. It requires airlines to replace specific flight control parts before they reach a certain age, preventing failures caused by metal fatigue.

This rule means airlines can no longer wait for a part to fail before replacing it. Instead, they must track the age of these specific components and swap them out proactively. This shifts the maintenance strategy from reactive fixes to scheduled preventative work, adding a predictable cost to operating these aircraft.
