Federal Register / Vol. 86, No. 161 / Tuesday, August 24, 2021 / Proposed Rules
FAAs Determination and Requirements of This Proposed AD

Differences Between this Proposed AD
and the MCAI.

0692 after the FAA final rule is published.

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 pertinent information and determined an unsafe condition exists and is likely to exist or develop on 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 developed a process to use some civil aviation authority CAA
ADs as the primary source of information for compliance with requirements for corresponding FAA
ADs. The FAA has been coordinating this process with manufacturers and CAAs. As a result, the FAA proposes to incorporate ANAC AD 20200602R02
by reference in the FAA final rule. This proposed AD would, therefore, require compliance with ANAC AD 202006
02R02 in its entirety through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD.
Service information required by ANAC
AD 20200602R02 for compliance will be available at https
www.regulations.gov by searching for and locating Docket No. FAA2021

Differences Between This Proposed AD
and the MCAI

Proposed AD Requirements This proposed AD would require accomplishing the actions specified in ANAC AD 20200602R02 described previously, as proposed for incorporation by reference, except for any differences identified as exceptions in the regulatory text of this proposed AD, and except as discussed under
The applicability of ANAC AD 2020
0602R02 is limited to certain airplanes of the affected models. However, the applicability of this proposed AD
includes all airplanes. Because the affected lock assemblies are rotable parts, the FAA has determined that these parts could later be installed on airplanes that were initially delivered with the acceptable lock assemblies, thereby subjecting those airplanes to the unsafe condition. The FAA has confirmed that the requirement in paragraph w of ANAC AD 202006
02R02 is applicable to the expanded group of airplanes.
Costs of Compliance The FAA estimates that this proposed AD affects 85 airplanes of U.S. registry.
The FAA estimates the following costs to comply with this proposed AD:

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

Labor cost
The FAA has received no definitive data on which to base the cost estimates for the on-condition actions specified in this proposed AD.
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 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.

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
