What to do
Affected operators must perform repetitive special detailed inspections including rototests of the fastener holes at Frame 40 vertical web within specified thresholds or grace periods, depending on aircraft configuration. If cracks are found, corrective repairs must be carried out according to Airbus Repair Design Approval Sheets or service bulletin instructions. Compliance deadlines vary by aircraft model and configuration, with some inspections required within 18 to 24 months from specified effective dates.
Summary
EASA Airworthiness Directive 2018-0249R1 is a regulatory update addressing inspection and modification requirements for the centre wing box fastener holes at Frame 40 vertical web on Airbus A330 and A340 aeroplanes. It applies to multiple A330 and A340 variants, excluding those with specific Airbus Repair Instructions embodied. The directive mandates repetitive special detailed inspections and corrective actions to ensure structural integrity of the centre fuselage.
What changed
This revision corrects typographical errors, clarifies conditions for partial embodiment of optional modification service bulletins, and adjusts lower threshold calculations for certain modifications. It also deletes obsolete paragraphs related to Airworthiness Limitation Items and introduces additional credit for approved alternative methods of compliance. The directive extends compliance times for A330-200F models and updates references to the latest Airbus service bulletin revisions.
Why it matters
This directive is critical for maintaining the structural safety of affected Airbus A330 and A340 aircraft by preventing undetected cracks in the centre wing box area that could compromise fuselage integrity. Operators and maintenance organizations must comply to avoid unsafe conditions and ensure continued airworthiness. The updated inspection intervals and modification windows help optimize maintenance planning and reduce operational disruptions.
