Federal Register / Vol. 86, No. 148 / Thursday, August 5, 2021 / Rules and Regulations For the reasons discussed above, I
certify that this AD:
1 Is not a significant regulatory action under Executive Order 12866, 2 Will not affect intrastate aviation in Alaska, and 3 Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.
Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:

h Exceptions to EASA AD 20210035
1 Where EASA AD 20210035 refers to its effective date, this AD requires using the effective date of this AD.
2 The Remarks section of EASA AD
20210035 does not apply to this AD.
i No Reporting Requirement Although the service information referenced in EASA AD 20210035 specifies to submit certain information to the manufacturer, this AD does not include that requirement.

e Reason This AD was prompted by reports of missing or disbonded pressure seals on two thrust reverser TR translating cowls. The FAA is issuing this AD to address missing or disbonded TR translating cowl seal segments.
In a case where all seal segments were missing, this condition, if not addressed, could lead to loss of thrust at maximum continuous thrust or at takeoff/go-around, possibly resulting in substantially reduced performance of the airplane.

j Other FAA AD Provisions The following provisions also apply to this AD:
1 Alternative Methods of Compliance AMOCs: The Manager, Large Aircraft Section, International Validation Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or responsible Flight Standards Office, as appropriate. If sending information directly to the Large Aircraft Section, International Validation Branch, send it to the attention of the person identified in paragraph k of this AD.
Information may be emailed to: 9-AVS-AIR730-AMOC@faa.gov. Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the responsible Flight Standards Office.
2 Contacting the Manufacturer: For any requirement in this AD to obtain instructions from a manufacturer, the instructions must be accomplished using a method approved by the Manager, Large Aircraft Section, International Validation Branch, FAA; or EASA; or Airbus SASs EASA Design Organization Approval DOA. If approved by the DOA, the approval must include the DOA-authorized signature.
3 Required for Compliance RC: Except as required by paragraph j2 of this AD, if any service information contains procedures or tests that are identified as RC, those procedures and tests must be done to comply with this AD; any procedures or tests that are not identified as RC are recommended. Those procedures and tests that are not identified as RC may be deviated from using accepted methods in accordance with the operators maintenance or inspection program without obtaining approval of an AMOC, provided the procedures and tests identified as RC can be done and the airplane can be put back in an airworthy condition. Any substitutions or changes to procedures or tests identified as RC require approval of an AMOC.

f Compliance Comply with this AD within the compliance times specified, unless already done.
