What to do
Operators of Airbus A350-941 and A350-1041 aeroplanes must inspect their aircraft to determine if affected primary flight control actuators are installed. For aircraft with affected parts, replacement with serviceable actuators must be completed within 135 days from 2 August 2025. Additionally, no affected parts may be installed on any aircraft after the effective date. Compliance must follow the instructions in Airbus AOT A27P020-25 and the referenced Moog Service Bulletins.
Summary
EASA Airworthiness Directive 2025-0152 is an airworthiness directive addressing Airbus A350-941 and A350-1041 aeroplanes. It mandates the replacement of certain primary flight control actuators, including servo controls, electrical backup hydraulic actuators (EBHA), and electro-hydrostatic actuators (EHA), that were exposed to mechanical overloads during production. The directive aims to ensure continued safe operation of these aircraft by removing affected parts from service.
What changed
This new regulation introduces a requirement to identify and replace affected primary flight control actuators on Airbus A350 aircraft that have reduced fatigue life due to mechanical overloads during acceptance testing. It prohibits the installation of any affected parts after the effective date and requires replacement within 135 days for aircraft with affected parts installed. The directive references Airbus Alert Operators Transmission A27P020-25 and applicable Moog Service Bulletins for compliance instructions.
Why it matters
This directive is critical for aviation professionals because failure of the affected actuators could lead to loss of control of flight control surfaces or hydraulic system failure, compromising aircraft safety. Operators and maintenance organizations must ensure compliance to prevent potential in-flight control issues. The directive also impacts parts inventory management by prohibiting installation of affected actuators, requiring careful tracking and replacement planning.
