Summary
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A330-243, -243F, -341, -342, and -343 airplanes. This proposed AD was prompted by a determination that cracks can develop on the ripple damper weld of the hydraulic pressure tube assembly and reports of failure of the ripple damper of the hydraulic pressure tube assembly. This proposed AD would require replacement of the affected hydraulic pressure tube assembly or modification of both engines, as specified in a European Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
