What to do
Operators of Airbus A350-941 and A350-1041 aircraft must replace affected FCRMs within 24 days of the directive's effective date, 7 May 2025. They must also avoid swapping elevator or rudder FCRMs with aileron or spoiler FCRMs and replace any affected FCRMs if hydraulic leaks are detected before the next flight. Maintenance teams should follow Airbus Alert Operators Transmission A27P021-25 instructions and rectify any hydraulic leaks concurrently with FCRM replacement.
Summary
EASA Airworthiness Directive 2025-0099 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Airbus A350-941 and A350-1041 aeroplanes. It addresses the replacement and maintenance requirements of Flight Control Remote Modules (FCRM) due to hydraulic fluid contamination risks. The directive applies to specific FCRM part numbers and aims to prevent potential loss of control of rudder, elevator, or aileron surfaces.
What changed
This new directive introduces mandatory replacement of affected FCRMs contaminated by hydraulic fluid and prohibits swapping elevator or rudder FCRMs with aileron or spoiler FCRMs. It also requires additional maintenance actions, including replacing certain FCRMs within 24 days and rectifying related hydraulic leaks. The directive establishes new installation rules for serviceable FCRMs and servocontrols on affected aircraft.
Why it matters
This directive is critical for aviation professionals as it addresses a safety risk that could lead to loss of aircraft control due to contaminated flight control modules. Operators and maintenance organizations must comply to ensure continued airworthiness and prevent potential accidents. Compliance teams need to track affected aircraft and parts to meet the directive’s deadlines and maintenance requirements.
