Airbus A350s must now get regular checks for engine leaks that damage insulation

The US aviation regulator now requires all Airbus A350 airplanes to undergo regular tests for air leaks from a specific engine part. If leaks are found, the plane's insulation must be inspected for damage, and the faulty engine part replaced.

This rule means airlines operating Airbus A350s will have to spend more on maintenance and inspections. It addresses a specific safety issue where engine leaks could damage critical thermal insulation, which could lead to further problems. This is a routine but important safety update for a widely used long-haul aircraft.
