What to do
Affected operators must replace the specified screws on the NACA Vent Intake Panel within 21 months after the directive's effective date following Airbus Service Bulletin A330-55-3054. After completing the modification, maintenance personnel must avoid installing the older screw part number NAS1153V9 on the modified panels. Stakeholders should also submit any comments on the proposal before the consultation closes on 10 March 2026.
Summary
EASA Airworthiness Directive 26-029 is a proposed directive addressing Airbus A330 series aeroplanes, specifically models A330-202, A330-243, A330-243F, A330-302, A330-323, A330-343, A330-841, and A330-941 with certain modifications. The directive focuses on modifying the NACA vent intake panel installation on the stabilizers to prevent potential fuel leaks. This action is intended to enhance safety by reducing the risk of fire due to lightning ignition.
What changed
EASA Airworthiness Directive 26-029 introduces a requirement to replace screws Part Number NAS1153V9 with NAS1153V8 on the NACA Vent Intake Panel 346AB within 21 months of the directive's effective date. It also prohibits the installation of the older screw part number NAS1153V9 after the modification. This is a new regulation addressing a previously identified unsafe condition.
Why it matters
This directive is important for aviation professionals because it addresses a potential safety hazard involving fuel leaks and fire risk on Airbus A330 aircraft. Operators and maintenance teams must ensure compliance to maintain airworthiness and prevent incidents related to lightning ignition. The modification helps maintain the integrity of the horizontal tail plane and fuel system safety.
