Summary
EASA Airworthiness Directive 2022-0079-E is an emergency directive affecting Airbus A350-941 and A350-1041 aeroplanes equipped with the Flight Control and Guidance System X13 standard. It addresses a fault in the primary flight control computers that could cause both elevator actuators to be incorrectly flagged as faulty, potentially leading to loss of elevator control. The directive mandates operational and dispatch restrictions to mitigate this risk.
What Changed
This directive introduces amendments to the Airbus A350 Airplane Flight Manual and the Master Minimum Equipment List to incorporate temporary revisions and major event revisions. These changes impose operational and dispatch restrictions for affected aircraft with the FCGS X13 standard. It is an interim measure pending further regulatory action.
Why It Matters
This directive is critical for aviation professionals because it addresses a potential safety hazard that could result in loss of elevator control and thus compromise flight safety. Operators and maintenance teams must comply promptly to ensure continued airworthiness and regulatory compliance. Failure to implement these restrictions could lead to unsafe flight conditions and regulatory penalties.
What To Do
Operators must amend the applicable Airbus A350 Airplane Flight Manual by incorporating the specified temporary revisions within 7 days of the directive's effective date. They must also implement the instructions of the Master Minimum Equipment List Major Event Revision within the same timeframe. Flight crews should be informed of these changes and operate the aircraft accordingly.
