What to do
Operators of Airbus A350-941 and A350-1041 aeroplanes with affected CPIOM-J parts must replace these parts with serviceable ones within four months from 3 September 2025. Additionally, no affected CPIOM-J parts may be installed on any aircraft from the effective date. Maintenance teams should follow the instructions in Airbus AOT A42P003-25 and VSB C13210D-42-011 to perform the replacement.
Summary
EASA Airworthiness Directive 2025-0181 is an airworthiness directive addressing Airbus A350-941 and A350-1041 aeroplanes. It mandates the replacement of certain Core Processing Input and Output Modules J (CPIOM-J) due to a manufacturing quality issue identified by the part manufacturer, Thales. The directive applies to specific serial numbers of CPIOM-J parts installed on these aircraft.
What changed
This new airworthiness directive introduces a requirement to replace affected CPIOM-J parts with serviceable ones within four months of the effective date. It also prohibits the installation of affected parts on any Airbus A350-941 or A350-1041 aeroplane from the effective date onward. The directive is based on Airbus Alert Operators Transmission A42P003-25 and Vendor Service Bulletin C13210D-42-011.
Why it matters
This directive is critical for aviation professionals because the affected CPIOM-J parts have a potential quality defect that could lead to loss of AFDX communication, risking partial or total loss of avionics systems. Compliance ensures continued airworthiness and operational safety of Airbus A350 aircraft. Operators, maintenance organizations, and compliance teams must address this to avoid unsafe conditions and regulatory non-compliance.
