EASA AD 2019-0123R1
SUPERSEDED BY EASA AD 2020-0157
Summary
EASA Airworthiness Directive 2019-0123R1 is an amendment addressing the Airbus A380-841, A380-842, and A380-861 aeroplanes regarding the landing gear gravity extension system. It mandates inspections and modifications to the wing landing gear emergency up-lock actuator wiring to prevent failure during gravity extension. This directive ensures continued airworthiness by requiring specific inspections and corrective actions to maintain safe landing gear operation.
What Changed
This revision clarifies the terminating action statement to avoid misunderstandings and requires additional work for aeroplanes modified with earlier versions of the applicable service bulletin. It retains the inspection and modification requirements from previous ADs but updates instructions to include inspection of wire terminations in the new harness bundle.
Why It Matters
This directive is critical for operators and maintenance organizations to prevent potential failure of the wing landing gear emergency gravity extension system caused by wiring fatigue. Compliance ensures safe landing operations and avoids possible unsafe conditions that could compromise aircraft safety. It also provides clear guidance on inspection intervals and modification procedures to maintain regulatory compliance.
What To Do
Operators must perform detailed or general visual inspections and on-ground gravity extension tests of the wing landing gear up-lock emergency actuator wiring within specified compliance times and every six months thereafter. Any discrepancies found must be corrected before the next flight. Additionally, the wing landing gear electrical harnesses must be modified within 36 months after 10 August 2017, with further additional work required within 12 months after the effective date of this AD for certain modified aeroplanes.
