Federal Register / Vol. 86, No. 42 / Friday, March 5, 2021 / Rules and Regulations
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 This AD will not have federalism implications under Executive Order 13132. This AD will 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 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.

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

20210414 Airbus SAS: Amendment 39
21435; Docket No. FAA20201106;
Project Identifier MCAI202001065T.

Jkt 253001

b Affected ADs None.
c Applicability This AD applies to Airbus SAS Model A350941 and A3501041 airplanes, certificated in any category, as identified in European Union Aviation Safety Agency EASA AD 20200166, dated July 27, 2020
EASA AD 20200166.
d Subject Air Transport Association ATA of America Code 53, Fuselage.
e Reason This AD was prompted by reports that suitable corrosion protection treatment had not been applied to certain areas of the seat track. The FAA is issuing this AD to address a potential structural deficiency at certain seat track locations, providing insufficient resistance to environmental damage. This condition, if not addressed, could lead to seat or monument detachment during an emergency landing, possibly resulting in injury to occupants and preventing safe evacuation from the airplane.
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, EASA AD 20200166.
h Exceptions to EASA AD 20200166
1 Where EASA AD 20200166 refers to its effective date, this AD requires using the effective date of this AD.
2 The Remarks section of EASA AD
20200166 does not apply to this AD.
3 Where paragraph 2 of EASA AD 2020
0166 refers to deficiencies, for this AD
deficiencies include unsuitable corrosion protection or presence of corrosion.
i No Reporting Requirement Although the service information referenced in EASA AD 20200166 specifies to submit certain information to the manufacturer, this AD does not include that requirement.

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:

39.13

a Effective Date This airworthiness directive AD is effective April 9, 2021.

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.
