What to do
Operators of Airbus A350-941 and A350-1041 aircraft must perform a one-time health check of the slat PCU torque sensing units, detailed inspections of the slat transmission systems, and cleaning of water drainage and vent plugs on track 12 SGRA if the aircraft met specified conditions as of 27 July 2020. These actions must be completed within 60 days after 27 July 2020. Any discrepancies found require immediate corrective actions before further flight, and inspection results must be reported to Airbus within 30 days of completion.
Summary
EASA Airworthiness Directive 2020-0163R2 is an updated safety directive addressing Airbus A350-941 and A350-1041 aeroplanes. It mandates inspections and corrective actions related to the slat transmission shafts and slat power control unit torque sensing units to prevent slat system jams during landing. The directive aims to ensure continued airworthiness by requiring health checks, detailed inspections, and cleaning procedures on affected components.
What changed
This revision corrects an error in the effective date referenced in the previous version, EASA AD 2020-0163R1, and clarifies inspection applicability and reporting requirements. It maintains the interim nature of the directive and continues to require inspections and corrective actions as specified in the original AD and its first revision.
Why it matters
This directive is critical for aviation professionals as it addresses a potential unsafe condition that could lead to slat transmission shaft disconnection, resulting in reduced aircraft control during flight. Operators and maintenance teams must comply to prevent slat system failures, ensuring flight safety and regulatory compliance. The directive also provides clear guidance on inspection and corrective procedures to mitigate risks associated with slat system wear and malfunction.
