Federal Register / Vol. 86, No. 33 / Monday, February 22, 2021 / Proposed Rules
FAAs Determination and Requirements of This Proposed AD

identified as exceptions in the regulatory text of this AD.

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 proposing this AD
because the FAA evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design.

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
20200227 will be incorporated by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 20200227
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
Proposed AD Requirements This proposed AD would require accomplishing the actions specified in EASA AD 20200227 described previously, as incorporated by reference, except for any differences
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
20200227 that is required for compliance with EASA AD 20200227
will be available on the internet at https www.regulations.gov by searching for and locating Docket No.
FAA20201184 after the FAA final rule is published.
Costs of Compliance The FAA estimates that this proposed AD affects 3 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
1 work-hour $85 per hour = $85

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.

ATRGIE Avions de Transport Regional:
Docket No. FAA20201184; Project Identifier MCAI202001425T.
a Comments Due Date The FAA must receive comments on this airworthiness directive AD action by April 8, 2021.
b Affected ADs None.
c Applicability This AD applies to ATRGIE Avions de Transport Regional Model ATR72212A
airplanes, certificated in any category, as identified in European Union Aviation Safety Agency EASA AD 20200227, dated October 19, 2020 EASA AD 20200227.
d Subject Air Transport Association ATA of America Code 92, Electrical Routing.
e Reason This AD was prompted by a report of an engine electrical control 1 fault during flight caused by chafing damage on an electrical harness bundle. The FAA is issuing this AD
to address such damage, which could result in wire failure and a short circuit, an uncontrolled fire, and consequent loss of multiple systems, possibly resulting in reduced controllability of the airplane.
f Compliance
2. The FAA amends 39.13 by adding the following new airworthiness directive:
