What to do
Operators of Airbus A380-841, A380-842, and A380-861 must perform a detailed inspection of the RAT wiring routing within 24 months from 1 May 2020, following Airbus Service Bulletin A380-92-8119. If any discrepancies are found, corrective actions must be completed before the next flight. Compliance with these instructions is mandatory to continue aircraft operation.
Summary
EASA Airworthiness Directive 2020-0088 is an airworthiness directive issued for Airbus A380-841, A380-842, and A380-861 aeroplanes. It addresses the inspection of the Ram Air Turbine (RAT) wiring routing within the electric and electronic common installation to ensure proper installation and prevent interference. The directive mandates a one-time detailed inspection of the affected RAT feeder and exciter wiring routes to detect and correct any installation discrepancies.
What changed
EASA Airworthiness Directive 2020-0088 introduces a new requirement for a one-time detailed inspection of the RAT wiring routing on Airbus A380 aircraft. It specifies inspection procedures and corrective actions based on findings to prevent potential chafing and ensure the RAT can deliver electrical power when needed. This directive does not supersede any previous ADs.
Why it matters
This directive is critical for aviation professionals because improper installation of RAT wiring can lead to chafing and failure of the RAT to supply electrical power during emergencies. Operators and maintenance organizations must ensure compliance to maintain aircraft safety and airworthiness. It helps prevent potential in-flight electrical power loss, which is vital for safe aircraft operation.
