Airworthiness Directives; Airbus SAS Airplanes

The FAA proposes to supersede Airworthiness Directive (AD) 2016-20-12, AD 2018-17-21, and AD 2019-14-04, which apply to certain Airbus SAS Model A318, A319, A320, and A321 series airplanes. AD 2019- 14-04 requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations and terminates the provisions of AD 2018-17-21, which in turn terminates the provisions of AD 2016-20-12. Since the FAA issued AD 2019-14-04, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, 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.
