EASA AD 2025-0289
Wings — Centre Wing Box Fastener Holes at Frame 40 Vertical Web — Inspection
Summary
EASA Airworthiness Directive 2025-0289 is an airworthiness directive issued by EASA concerning Airbus A330-743L aeroplanes. It mandates inspections of the centre wing box fastener holes at Frame 40 vertical web to detect cracks that could compromise the structural integrity of the aircraft's centre fuselage. The directive applies to all manufacturer serial numbers of the Airbus A330-743L.
What Changed
This new directive introduces mandatory inspections and corrective actions for cracks found in the fastener holes at Frame 40 on Airbus A330-743L aircraft. It establishes inspection intervals and repair requirements based on whether the aircraft has had prior repairs in the affected area. The directive also clarifies that repairs do not terminate the need for repetitive inspections unless otherwise specified.
Why It Matters
This directive is critical for maintaining the structural safety of the Airbus A330-743L by preventing undetected cracks from compromising the centre fuselage. Operators, maintenance organizations, and compliance teams must ensure timely inspections and repairs to avoid potential structural failures. Adhering to these requirements helps maintain airworthiness and regulatory compliance under EASA regulations.
What To Do
Operators of Airbus A330-743L aircraft must perform inspections before exceeding 17,600 flight cycles or 28,180 flight hours, depending on whether the aircraft has prior repairs in the affected area. Group 2 aircraft require repetitive detailed inspections every 4,100 flight cycles or 6,570 flight hours. If cracks are found, corrective actions must be taken before the next flight following Airbus instructions. Compliance with these actions is mandatory from 31 December 2025.
