## Abstract

We are superseding Airworthiness Directive (AD) 2015-15-13, which applied to certain Airbus Model A319 series airplanes; Model A320-211, -212, -214, -231, -232, and -233 airplanes; and Model A321- 111, -112, -131, -211, -212, -213, -231, and -232 airplanes. AD 2015- 15-13 required a modification of the potable water service panel and waste water service panel, including doing applicable related investigative and corrective actions. This AD requires a modification of the waste water and potable water service panels with new compliance times. This AD also removes certain airplanes from the applicability and adds Model A320-216 airplanes to the applicability. This AD was prompted by an evaluation by the design approval holder (DAH) indicating that the potable water and waste water service panel areas are subject to widespread fatigue damage (WFD). We are issuing this AD to address the unsafe condition on these products.
