SUPERSEDED BY EASA AD 2022-0022
Summary
EASA Airworthiness Directive 2021-0285 is an airworthiness directive issued for Airbus A380-841, A380-842, and A380-861 aeroplanes. It addresses a fatigue issue in certain aileron servo controls with part numbers 31132-130 and 31132-170, which could lead to failure or detachment of the servo control and potentially reduce aircraft control.
What Changed
This directive requires the removal and replacement of affected aileron servo controls before they exceed 8,170 flight cycles after their modification embodiment date. It prohibits the installation of affected parts after replacement and mandates compliance with Airbus and Goodrich Actuation Systems service bulletins for identification and corrective action.
Why It Matters
This AD is critical for maintaining the safe flight control of Airbus A380 aircraft by preventing potential failure of aileron servo controls due to fatigue. Operators, maintenance organizations, and compliance teams must ensure timely replacement of affected parts to avoid reduced aircraft controllability and ensure regulatory compliance.
What To Do
Operators must identify affected aileron servo controls using Airbus and Goodrich service bulletins or maintenance records and replace them with serviceable parts before the affected parts exceed 8,170 flight cycles post-modification. After replacement, installation of affected parts is prohibited. Compliance must follow the instructions detailed in the referenced service bulletins.
