The Federal Aviation Administration (FAA) has issued a new rule replacing a previous Airworthiness Directive (AD) concerning specific models of Leonardo S.p.A. helicopters. This new AD requires ongoing inspections and maintenance of the tail rotor duplex bearing to ensure the safety and stability of the aircraft. The rule, effective April 1, 2021, anticipates monitoring for any unsafe conditions in these helicopters due to incorrect installations that could lead to loss of control. It sets forth clear procedures operators must follow to comply with these requirements, including removing specific parts if defects are found.
Simple Explanation
The FAA is making sure that helicopters from a company called Leonardo stay safe by having people check and fix some important parts regularly. This is to prevent any problems that might make the helicopters not work well or safely.
