Airbus helicopters need a one-time inspection for a specific part after reports of excessive vibrations

The US aviation regulator proposes a new rule for a specific model of Airbus helicopter. It requires a one-time inspection of a part called the swashplate, which helps control the helicopter's rotor blades.

This rule means operators of these helicopters must check for a specific installation error that can cause dangerous vibrations. It prevents a known safety issue from causing accidents. The rule also stops affected parts from being installed on other helicopters.
