Federal Register / Vol. 86, No. 126 / Tuesday, July 6, 2021 / Proposed Rules reducing the cost impact on affected operators. The FAA does not control warranty coverage for affected operators.
As a result, the FAA has included all known costs in the cost estimate.
Authority for This Rulemaking Title 49 of the United States Code specifies the FAAs authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII:
Aviation Programs, describes in more detail the scope of the Agencys authority.
The FAA is issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701: General requirements. Under that section, Congress charges the FAA
with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce.
This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action.
Regulatory Findings The FAA determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would not have a substantial direct effect on the States, on the relationship between the national Government and the States, or on the distribution of power and responsibilities among the various levels of government.
For the reasons discussed above, I
certify this proposed regulation:
1 Is not a significant regulatory action under Executive Order 12866, 2 Would not affect intrastate aviation in Alaska, and 3 Would not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39AIRWORTHINESS
DIRECTIVES
1. The authority citation for part 39
continues to read as follows:

VerDate Sep<11>2014

Jkt 253001

Authority: 49 U.S.C. 106g, 40113, 44701.
39.13

Amended
2. The FAA amends 39.13 by adding the following new airworthiness directive:

Airbus SAS: Docket No. FAA20210545;
Project Identifier MCAI202100071T.
a Comments Due Date The FAA must receive comments on this airworthiness directive AD by August 20, 2021.
b Affected ADs None.
c Applicability This AD applies to all Airbus SAS Model A350941 and 1041 airplanes, certificated in any category.
d Subject Air Transport Association ATA of America Code 52, Doors.
e Reason This AD was prompted by a report of a broken forward guide arm found during a passenger door emergency opening test.
Investigation results indicated that the opening speed of the door was higher than expected, likely caused by a reduced damping due to oil leakage of the passenger door damper emergency opening actuator DEOA. The FAA is issuing this AD to address failure of a passenger door to perform its intended function during an emergency opening, which could result in reduced evacuation capacity from the airplane and injury to occupants.
f Compliance Comply with this AD within the compliance times specified, unless already done.
g Requirements Except as specified in paragraph h of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency EASA EASA AD 20210085, dated March 19, 2021 EASA AD 20210085.
h Exceptions to EASA AD 20210085
1 Where EASA AD 20210085 refers to January 29, 2021 the effective date of EASA
AD 20210018, this AD requires using the effective date of this AD.
2 Where EASA AD 20210085 refers to its effective date, this AD requires using the effective date of this AD.
3 The Remarks section of EASA AD
20210085 does not apply to this AD.
4 Where paragraphs 4 and 5 of EASA
AD 20210085 refer to the limits as defined in the inspection SB service bulletin, for this AD use the limits as defined in ASR
aircraft structural repair A350A5173
1101ZZZ667ZA.
5 Where paragraphs 1 and 2 of EASA
AD 20210085 specify to replace the forward and aft guide arms on that door in accordance with the instructions of the inspection SB, this AD requires removing

the forward and aft guide arms on that door, in accordance with the instructions of the inspections SB; doing a detailed inspection of the forward and aft guide arm support bracket on that door and all applicable corrective actions as specified in paragraphs 3 through 5 of EASA AD 20210085; and installing new forward and aft guide arms on that door, in accordance with the instructions of the inspections SB.
i No Reporting Requirement Although the service information referenced in EASA AD 20210085 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
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 k2 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.
