EASA AD 2025-0237R1
Equipment / Furnishings – 80 VU Rack Attachments – Inspection / Repair
Summary
EASA Airworthiness Directive 2025-0237R1 is an updated regulatory requirement addressing inspection and repair of the 80 VU rack attachments on Airbus A318, A319, A320, and A321 aeroplanes. This directive applies to various configurations including both Current Engine Option (CEO) and New Engine Option (NEO) models. It mandates repetitive inspections of specific rack zones to detect damage such as elongated holes, migrated bushes, missing bolts, and cracking that could compromise flight control and communication systems.
What Changed
EASA Airworthiness Directive 2025-0237R1 revises the previous AD 2025-0237 by updating repair instructions specifically for NEO aeroplanes and correcting erroneous references in the Airbus service bulletin applicable to these models. It also adjusts inspection intervals for certain aeroplane groups based on additional analysis, extending intervals for Group 4 aeroplanes while maintaining existing intervals for Groups 1, 2, and 3. This revision incorporates Airbus SB A320-25-1CJH Revision 02 for NEO aeroplanes and updates compliance requirements accordingly.
Why It Matters
This directive is critical for aviation professionals as it ensures the structural integrity of the 80 VU rack, which houses essential flight control, communication, and radio-navigation computers. Failure to comply could lead to multiple system failures or partial disconnection during critical flight phases, potentially reducing aircraft control. Operators, maintenance organizations, and compliance teams must adhere to these inspections and repairs to maintain airworthiness and regulatory compliance.
What To Do
Affected operators must perform Special Detailed Inspections of the 80 VU rack attachments before exceeding specified flight cycle thresholds or within defined intervals depending on the aeroplane group and zone. Inspections and any necessary repairs must follow the instructions in the applicable Airbus service bulletins and repair instructions. Compliance deadlines vary by group and zone but generally require action before exceeding 19,500 flight cycles or within 500 flight cycles after the last inspection or repair.
