European and U.S. aviation regulators expanded an airworthiness directive for Airbus A318 to A321 aircraft.
The expansion adds more aircraft to a mandate requiring inspections and potential replacements of main landing gear door actuators.
The action follows safety investigations into potential system malfunctions that could pose risks during landing or evacuation.
The directive affects the Airbus A320 family, a core product line for global short and medium-haul routes.
Airlines must add these inspections and replacements to maintenance schedules.
These tasks could increase costs and cause minor operational adjustments.
This order is one of several recent safety directives for the A320 family.
In late May 2026, the U.S. Federal Aviation Administration adopted rules for potential rudder stability issues.
The agency also mandated inspections for fastener holes related to manufacturing deviations.
