What to do
Operators must perform wake-up tests on affected TRCS parts within specified flight hour limits and every 2,000 flight hours thereafter. If a part fails inspection, corrective actions must be taken before the next flight and results reported to Airbus within 30 days. All affected parts must be replaced with serviceable parts within 46 months from 19 December 2022, which is the effective date of the directive.
Summary
EASA Airworthiness Directive 2022-0238 is an airworthiness directive affecting Airbus A380-841, A380-842, and A380-861 aeroplanes. It addresses corrosion issues found on the triple reed contact switches (TRCS) used in the doors and slide management system. The directive mandates inspections and replacement of affected Diehl Aerospace GmbH TRCS parts to ensure proper door functionality and evacuation capability.
What changed
This directive supersedes EASA AD 2020-0032 and introduces a requirement to replace the affected TRCS parts with new serviceable parts made of passivated steel instead of aluminium. It retains the repetitive inspection requirements from the previous AD until the replacement is completed and prohibits reinstallation of the affected parts after replacement.
Why it matters
The corrosion on the TRCS interface can lead to door failure, reducing evacuation capacity and potentially causing injury during emergencies. Compliance with this directive ensures continued airworthiness and safety of the Airbus A380 doors and slide systems. Operators and maintenance teams must manage inspections and part replacements to avoid operational disruptions and regulatory non-compliance.
