Airworthiness Directives; Airbus SAS Airplanes

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A319-111, -112, -113, -114, -115, -131, - 132, -133 airplanes. This proposed AD was prompted by a widespread fatigue damage (WFD) scenario review for a certification project that indicated several cracks found around the potable water and wastewater service panels were WFD instead of typical fatigue. This proposed AD would require modification of the potable water and wastewater service panels, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
