concentration rate in the material of the affected screws that was above the allowable limit. The FAA is proposing this AD to address failure of an affected screw installed in a critical location, possibly resulting in reduced structural integrity of the airplane. See the MCAI
for additional background information.
Related Service Information Under 1
CFR Part 51
EASA AD 20210047 describes procedures for replacement of certain Decomatic titanium screws including an inspection of the bore dimension and corrective actions oversizing or repair.
The EASA AD also restricts installation of certain Decomatic titanium screws.
This material is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section.
FAAs Determination and Requirements of This Proposed 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.
Proposed AD Requirements This proposed AD would require accomplishing the actions specified in EASA AD 20210047 described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this AD.
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 EASA AD 20210047 by
reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 20210047
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 EASA AD 20210047 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 EASA AD 20210047.
Service information required by EASA
AD 20210047 for compliance will be available at https www.regulations.gov by searching for and locating Docket No.
FAA20210684 after the FAA final rule is published.
Costs of Compliance The FAA estimates that this proposed AD affects 30 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
Up to 90 work-hours $85 per hour = Up to $7,650

Cost on U.S.
operators
Cost per product $0

Up to $7,650

Up to $229,500.

The FAA has received no definitive information regarding cost estimates for these parts.

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.

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
