What to do
Affected operators must modify the hydraulic monitoring and control application software within 6 to 12 months depending on the aircraft group and amend the Aircraft Flight Manual within 3 months for Group 1 aircraft. Additionally, within 40 months, they must replace all affected engine-driven pumps with improved parts. Installation of outdated software or parts is prohibited from the effective date of the directive. Stakeholders should refer to the specified Airbus Service Bulletins for detailed instructions.
Summary
EASA Airworthiness Directive 26-032 is a proposed directive addressing hydraulic power issues related to the engine-driven pump software and Aircraft Flight Manual amendments for Airbus A350-941 and A350-1041 aeroplanes. It applies to aircraft except those with Airbus modifications 116830 and 117811 incorporated in production. The directive focuses on updating software and replacing affected engine-driven pumps to prevent overheating and potential hydraulic system failures.
What changed
This directive supersedes EASA AD 2025-0139 and retains its requirements while introducing a new mandate to replace affected engine-driven pumps with improved parts having Part Number 53098-07. It also requires updating the hydraulic monitoring and control application software and amending the Aircraft Flight Manual to reflect these changes. The directive clarifies applicability and compliance timelines for different aircraft groups based on installed software and parts.
Why it matters
This directive is critical for maintaining the safety and airworthiness of Airbus A350 aircraft by addressing repeated engine-driven pump overheating events that could lead to hydraulic system failures. Operators and maintenance organizations must comply to ensure the hydraulic system's reliability and prevent potential in-flight emergencies. Compliance also ensures adherence to European Union aviation safety regulations and avoids operational disruptions.
