What to do
Operators of Airbus A350-941 and A350-1041 aircraft must amend the applicable AFM by incorporating the specified AFM Temporary Revision within three months from 21 May 2025. Flight crews must be informed of the changes and operate the aircraft accordingly. Using later approved AFM revisions containing the same content is also acceptable for compliance.
Summary
EASA Airworthiness Directive 2025-0105 is an amendment concerning Airbus A350-941 and A350-1041 aeroplanes. It addresses limitations related to derated take-off operations by requiring updates to the Airbus A350 Airplane Flight Manual (AFM) through specific Temporary Revisions. The directive ensures safe operation by mitigating potential thrust asymmetry issues during critical flight phases.
What changed
This directive mandates the incorporation of Airbus A350 AFM Temporary Revisions 137, 139, 142, or 143, depending on the aircraft model and configuration, to amend the derated take-off limitations. These revisions introduce operational limitations to prevent thrust asymmetry caused by the interaction of derated logic and engine control laws under Keep Out Zone restrictions. The amendment requires updating the AFM within three months of the effective date.
Why it matters
The directive is crucial for operators and maintenance teams as it addresses a safety risk that could increase pilot workload and reduce aircraft control during take-off. Compliance ensures continued airworthiness and adherence to European Union aviation safety regulations. It also helps avoid potential incidents related to engine thrust imbalance during derated take-off procedures.
