AD FAA-2020-1105

The FAA is superseding Airworthiness Directive (AD) 2020-01- 17, which applied to all Airbus SAS Model A318, A319, A320, and A321 series airplanes. AD 2020-01-17 required 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. This AD retains the requirements of AD 2020-01-17, expands the list of affected parts to be checked, and provides optional terminating action for the repetitive checks; as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD was prompted by the determination that certain parts that were not identified in AD 2020-01-17 are also subject to the unsafe condition. The FAA is issuing this AD to address the unsafe condition on these products.
