Federal Register / Vol. 86, No. 33 / Monday, February 22, 2021 / Proposed Rules
use this process. As a result, EASA AD
20200234 will be incorporated by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 20200234
in its entirety, through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed 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
20200234 that is required for compliance with EASA AD 20200234
will be available on the internet at
https www.regulations.gov by searching for and locating Docket No.
FAA20210014 after the FAA final rule is published.
Costs of Compliance The FAA estimates that this proposed AD affects 6 airplanes of U.S. registry.
The FAA estimates the following costs to comply with this proposed AD:

ESTIMATED COSTS FOR REQUIRED ACTIONS
Labor cost
Parts cost
Cost per product
Cost on U.S.
operators
14 work-hours $85 per hour = $1,190

$1,900

$3,090

$18,540

According to the manufacturer, some or all of the costs of this proposed AD
may be covered under warranty, thereby reducing the cost impact on affected individuals. The FAA does not control warranty coverage for affected individuals. As a result, the FAA has included all known costs in the cost estimate.

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.

Authority for This Rulemaking
List of Subjects in 14 CFR Part 39

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:

d Subject Air Transport Association ATA of America Code 53, Fuselage.
e Reason This AD was prompted by a report indicating occurrences of broken brackets of the support structure of the halon fire extinguishing bottle 4005WX; investigation showed that fatigue cracks initiated in the attachment brackets at the cross beams due to dynamic loading, and in some cases propagated in the struts. The FAA is issuing this AD to address fatigue cracking on the attachment brackets, which could lead to damage of the tubing and electrical wiring of the lower deck cargo compartment LDCC
fire extinguishing system, and possibly result in insufficient fire suppression capability in the LDCC.
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 20200234.
h Exceptions to EASA AD 20200234
1 Where EASA AD 20200234 refers to its effective date, this AD requires using the effective date of this AD.
2 The Remarks section of EASA AD
20200234 does not apply to this AD.
i 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.
