SUPERSEDED BY EASA AD 2020-0203
Summary
EASA Airworthiness Directive 2020-0090R1 is an amendment addressing safety concerns on Airbus A350-941 and A350-1041 aeroplanes related to inadvertent liquid spillage on the ENG START panel or Electronic Centralized Aircraft Monitoring Control Panel. This directive mandates modifications and operational changes to prevent uncommanded engine in-flight shutdowns caused by liquid contamination. It applies to all affected A350 aircraft except those with specific water-resistant modifications.
What Changed
This revision excludes Airbus A350 aeroplanes that have incorporated modification 116038, which introduces a water-resistant ENG START panel and control panel cover, from the applicability of the directive. It retains previous requirements for installing a removable cover on the integrated control panel and updating the Airplane Flight Manual with new procedures. The directive remains an interim action pending further updates.
Why It Matters
This directive is critical for operators and maintenance teams to prevent potentially hazardous dual engine shutdowns caused by liquid spillage in the cockpit control panels. Compliance ensures continued airworthiness and safety of Airbus A350 aircraft by mitigating risks of forced landings and occupant injury. It also affects flight crew procedures and aircraft configuration during flight phases.
What To Do
Operators must amend the Airplane Flight Manual by incorporating the specified temporary revisions before the next flight after 7 February 2020. They are required to install the integrated control panel removable cover within 28 days after 24 April 2020 and update the AFM accordingly before the next flight post-modification. Flight crews must be informed of these changes and operate the aircraft following the updated procedures.
