As well as this, the aviation safety agency said that all main gearboxes that have suffered from unusual events will be withdrawn from service.
The agency noted further that it will closely monitor the compliance action taken by the helicopter manufacturer and operators following the return to service along with operational information.
EASA has been closely monitoring the analysis and tests conducted by Airbus Helicopters, the agency explained.
