Airworthiness Directive · Amendment 39-19496 · Water/waste
Airbus SAS Airplanes
This AD applies to Airbus SAS Model A350-941 airplanes, certificated in any category, except those on which Airbus modification (mod) 111435 or mod 111440 has been embodied in production.
We are adopting a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 airplanes. This AD was prompted by leakage of shrouded pipe T-boxes in the potable water system. This AD requires replacement of the affected potable water T-boxes and clamps with new parts. We are issuing this AD to address the unsafe condition on these products.
Within 36 months after the effective date of this AD: Replace the affected potable water T-boxes and clamps with new parts in accordance with the Accomplishment Instructions of Airbus Service Bulletin A350-38-P004, dated April 11, 2018.
Note 1 to paragraph (g) of this AD: Airbus Maintenance Procedure (MP) Task A350-A-20-51-64-01001-25BA-A provides additional information for installing and torqueing the hardware.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
