What to do
Operators must inspect the affected main rotor swashplate assemblies within specified flight hour intervals, starting no later than 50 flight hours after the effective date or based on accumulated flight hours since installation or last functional maintenance check. Any discrepancies found require immediate replacement of the affected part before further flight. Installation of affected parts is permitted only if they are serviceable and inspected as required.
Summary
EASA Airworthiness Directive 2020-0081 is an airworthiness directive issued for Airbus Helicopters EC175 B models. It addresses a manufacturing defect in the ceramic balls of the main rotor swashplate bearing, which could lead to premature bearing failure and reduced helicopter control. The directive mandates repetitive inspections and potential replacement of affected main rotor swashplate assemblies.
What changed
This directive introduces mandatory repetitive inspections of the main rotor swashplate assemblies with specific part numbers M623A2A13052 and M623A2A13054. It requires replacement of any defective parts found during inspections and allows installation of affected parts only if they are serviceable and inspected accordingly. This AD is an interim measure pending further action.
Why it matters
This directive is critical for aviation professionals to prevent potential loss of main rotor bearing function, which could compromise helicopter control and safety. Operators and maintenance organizations must ensure compliance to avoid unsafe conditions and regulatory violations. Timely inspections and corrective actions reduce the risk of in-flight failures and enhance continued airworthiness.
