## Summary

We propose to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 airplanes. This proposed AD was prompted by leakage of shrouded pipe T-boxes in the potable water system. This proposed AD would require replacement of the affected potable water T-boxes and clamps with new parts. We are proposing this AD to address the unsafe condition on these products.
