Airworthiness Directive · Amendment 39-14984 · Airbus Model A330 Airplanes
Airbus Model A330 Airplanes
This AD applies to Airbus Model A330 airplanes, all certified models, certificated in any category, all serial numbers up to 755 included.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an airworthiness authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as an incomplete discharge of the extinguishing agent in the fire zone, which could lead, in the worst case, in combination with an engine fire, to a temporary uncontrolled engine fire. We are issuing this AD to require actions to correct the unsafe condition on these products.
Unless already done, do the following actions. Within 900 flight hours from the effective date of this AD: On both engine pylons (left hand and right hand), for all four engine fire extinguisher bottles, two per engine pylon, perform a one-time detailed visual inspection for the presence of the retaining ring on the discharge head of the bottles and apply all applicable corrective actions, in accordance with instructions defined in Airbus Service Bulletin A330-26A3037, dated July 26, 2006. Do all applicable corrective actions before further flight. Aircraft on which the four engine fire extinguishing bottles, 2 per engine pylon, have been removed and re-installed at the opportunity of hydrostatic test of engine fire extinguishing as per Airbus A330 Maintenance Review Board Report (MRBR) task 26.21.00/04, are not concerned by this AD.
