AD FAA-2019-1080

The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A318 series airplanes; Model A319 series airplanes; Model A320 series airplanes; and Model A321 series airplanes. This AD was prompted by a report that during airplane boarding a loud bang was heard. A subsequent inspection revealed that one emergency escape slide/raft was found with zero reservoir pressure, due to a burst rupture disk assembly in the inflation reservoir, which was probably caused by a manufacturing defect. This AD requires repetitive checks of the pressure gauges on the inflation reservoir of each emergency escape slide/raft to determine the amount of pressure and, depending on findings, accomplishment of applicable corrective actions, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
