## Summary

We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A330-200 Freighter, A330-200, A330-300, A340-200, A340-300, A340-500, and A340-600 series airplanes. This proposed AD was prompted by a determination that a functional test to ensure that there is no blockage of vent pipes was not done on the trim tank of certain airplanes during production. This proposed AD would require doing a trim tank functional test, and corrective actions if necessary. We are proposing this AD to address the unsafe condition on these products.
