What to do
Operators of Airbus A380-841, A380-842, and A380-861 aeroplanes must identify if affected aileron servo controls are installed and replace them with serviceable parts before the affected parts exceed 8,170 flight cycles after modification embodiment. Installation of affected parts is prohibited from the effective date for aeroplanes without affected parts and after replacement for those with affected parts. Compliance must be achieved by 16 February 2022.
Summary
EASA Airworthiness Directive 2022-0022 is an official regulatory document addressing the replacement of aileron servo controls on Airbus A380-841, A380-842, and A380-861 aeroplanes. The directive targets specific part numbers of aileron servo controls that may suffer from a fatigue issue potentially leading to failure or detachment, which could reduce aircraft control. It mandates removal of affected parts and installation of serviceable parts to ensure continued airworthiness.
What changed
EASA Airworthiness Directive 2022-0022 supersedes the previous AD 2021-0285 and clarifies the requirements by introducing group definitions to distinguish between aeroplanes with affected parts installed and those without. It retains the removal and replacement requirements for affected parts but specifies compliance times and installation prohibitions more clearly. The directive also incorporates references to updated service bulletins for identification and corrective actions.
Why it matters
This directive is critical for aviation professionals because it addresses a potential safety risk related to aileron servo control fatigue, which could compromise flight control. Operators and maintenance organizations must ensure affected parts are identified and replaced within specified flight cycle limits to maintain regulatory compliance and aircraft safety. Clear group definitions help streamline maintenance planning and parts management.
