Actions completed in accordance with earlier revisions of the service bulletin are acceptable for compliance.
Summary
EASA Airworthiness Directive 2024-0170 is an airworthiness directive addressing inspection and modification of the wing stringer joint at Rib 18 on Airbus A300-600 series aeroplanes, including models A300B4-603, A300B4-605R, A300B4-622, A300B4-622R, A300C4-605R variant F, A300C4-620, A300F4-605R, and A300F4-622R. It mandates detailed visual inspections and modifications to prevent widespread fatigue damage in the wing structure. The directive applies to all manufacturer serial numbers of these aircraft types.
What changed
EASA Airworthiness Directive 2024-0170 supersedes the previous AD 2017-0023 and expands the applicability to include A300F4-605R aeroplanes in post-mod 12699 configuration and A300F4-622R aeroplanes. It updates inspection and modification requirements based on the latest Airbus Service Bulletin A300-57-6118 Revision 2, ensuring continued resistance against widespread fatigue damage within the established limits of validity.
Why it matters
This directive is critical for maintaining the structural integrity of Airbus A300-600 wings by addressing potential multi-element fatigue damage at the stringer joints. Operators and maintenance organizations must comply to prevent structural failures that could compromise flight safety. Compliance ensures adherence to regulatory requirements and prolongs the operational life of affected aircraft.
