AD FAA-2015-8463

We are superseding Airworthiness Directive (AD) 2013-20-11, for all Airbus Model A318, A319, A320, and A321 series airplanes. AD 2013-20-11 required modifying the passenger emergency oxygen container assembly. This new AD expands the affected group of oxygen containers to include those labeled "DAe Systems." This AD was prompted by a determination that the unsafe condition also affects oxygen containers labeled "DAe Systems." We are issuing this AD to prevent a high temperature oxygen generator and mask from falling down and possibly resulting in an ignition source in the passenger compartment, injury to passengers, and reduced availability of supplemental oxygen.
