The FAA is adopting a new airworthiness directive AD for certain Airbus SAS Model A319111, 112, 113, 114, 115, 131, 132, and 133
airplanes. This AD was prompted by a determination that the cabin swift broadband antenna doubler installation does not meet widespread fatigue damage WFD requirements. This AD
requires a one-time special detailed inspection of certain fastener holes, replacement of the cabin swift broadband antenna doubler, and repair if necessary, 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.
DATES: This AD becomes effective June 16, 2021.
The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD
as of June 16, 2021.
The FAA must receive comments on this AD by July 16, 2021.

SUPPLEMENTARY INFORMATION:
Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 20200218, dated October 12, 2020 EASA AD
20200218 also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI, to correct an unsafe condition for certain Airbus SAS
Model A319111, 112, 113, 114, 115, 131, 132, and 133 airplanes.
This AD was prompted by a determination that the cabin swift broadband antenna doubler installation does not meet WFD requirements. The FAA is issuing this AD to address the potential effects of WFD on the installation. This condition, if not corrected, could reduce the structural integrity of the fuselage. See the MCAI
for additional background information.
Related Service Information Under 1
CFR Part 51
EASA AD 20200218 describes procedures for accomplishing a special detailed inspection roto test high frequency eddy current of the affected fastener holes, repairing, if any cracks or other discrepancies e.g. oversized hole, corrosion, or other damage are found, and replacing the cabin swift broadband antenna doubler with a modified doubler.

This material is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section.
FAAs Determination This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to the FAAs bilateral agreement with the State of Design Authority, the FAA has been notified of the unsafe condition described in the MCAI referenced above. The FAA is issuing this AD
because the FAA evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.
Requirements of This AD
This AD requires accomplishing the actions specified in EASA AD 2020
0218 described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this AD.
Explanation of Required Compliance Information In the FAAs ongoing efforts to improve the efficiency of the AD
process, the FAA initially worked with Airbus and EASA to develop a process to use certain EASA ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has since coordinated with other manufacturers and civil aviation authorities CAAs to use this process. As a result, EASA AD
20200218 is incorporated by reference in this final rule. This AD, therefore, requires compliance with EASA AD
20200218 in its entirety, through that incorporation, except for any differences identified as exceptions in the regulatory text of this AD. Using common terms that are the same as the heading of a particular section in the EASA AD does not mean that operators need comply only with that section. For example, where the AD requirement refers to all required actions and compliance times, compliance with this AD requirement is not limited to the section titled Required Actions and Compliance Times in the EASA
AD. Service information specified in EASA AD 20200218 that is required for compliance with EASA AD 20200218
is available on the internet at https
www.regulations.gov by searching for and locating Docket No. FAA2021
0367.
