Airbus Model A330-322, -341, and -342 Airplanes; and Airbus Model A340-200 and -300 Series Airplanes
(c) This AD applies to Airbus Model A330-322, -341, and -342 airplanes; and Model A340-211, -212, -213, -311, -312, and -313 airplanes; certificated in any category; as identified in Airbus Service Bulletin A330-53-3132, Revision 02, dated April 26, 2004, and Airbus Service Bulletin A340-53-4139, Revision 02, dated April 26, 2004, as applicable.
(d) This AD results from a report of fatigue cracks that initiated in the duct structure of the ram air outlet, which is adjacent to the hydraulics compartment. The FAA is issuing this AD to prevent fatigue cracks in the duct structure of the ram air outlet, which could lead to hot air damage and consequent loss of function of the hydraulics systems.
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A330-322, -341, and -342 airplanes, and Model A340-200 and -300 series airplanes. This AD requires modifying the left and right ram air outlets of the two air conditioning packs. The modification includes replacing the old air outlet assembly with a new air outlet assembly, and modifying the web. This AD results from a report of fatigue cracks that initiated in the duct structure of the ram air outlet, which is adjacent to the hydraulics compartment. We are issuing this AD to prevent fatigue cracks in the duct structure of the ram air outlet, which could lead to hot air damage and consequent loss of function of the hydraulics systems.
(f) Before the airplane accumulates 12,000 total flight cycles, or within 60 days after the effective date of this AD, whichever occurs later: Modify the ram air outlet ducts of the two air conditioning packs in accordance with the applicable service bulletin in Table 1 of this AD.
