What to do
Operators of Airbus A350-941 and A350-1041 aircraft must replace affected FCRMs within specified deadlines—24 days for type 1 and 18 days for type 3 after 7 May 2025. Maintenance teams must not swap elevator or rudder FCRMs with aileron or spoiler units from 7 May 2025 onward and must address any hydraulic leaks before the next flight by replacing affected FCRMs. Installation of only serviceable FCRMs is allowed from the effective date of 12 June 2025.
Summary
EASA Airworthiness Directive 2025-0129 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Airbus A350-941 and A350-1041 aeroplanes. It addresses the replacement of Flight Control Remote Modules (FCRM) that have been exposed to hydraulic fluid contamination, which could lead to loss of control of flight control surfaces such as rudder and elevator. The directive applies to all manufacturer serial numbers of these aircraft models and references Airbus Alert Operators Transmission A27P021-25.
What changed
EASA AD 2025-0129 supersedes the previous AD 2025-0099 and introduces additional requirements for replacing certain FCRMs that were exposed to hydraulic contamination before aircraft delivery. It also updates maintenance instructions to manage hydraulic leaks and prohibits swapping elevator or rudder FCRMs with aileron or spoiler FCRMs. The directive extends replacement deadlines and clarifies installation rules for serviceable FCRMs.
Why it matters
This directive is critical for aviation professionals because hydraulic contamination of FCRMs can cause runaway flight control surfaces, risking aircraft control and safety. Operators and maintenance organizations must ensure compliance to prevent potential accidents and maintain airworthiness. The directive also impacts maintenance planning and parts management by restricting FCRM interchangeability and requiring timely replacements.
