CFR Part 51

identified as exceptions in the regulatory text of this proposed AD.

EASA AD 20180002 requires installation of certain Primus Epic system software, depending on the helicopter configuration. EASA AD
20180002 allows installation of Primus Epic system software on a helicopter after that helicopter has had the software upgrade installed.
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.

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 certain 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, EASA AD 20180002
will be incorporated by reference in the FAA final rule. This proposed AD
would, therefore, require compliance with EASA AD 20180002 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
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified in EASA AD 20180002, described previously, as incorporated by reference, except for any differences

particular section in EASA AD 2018
0002 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
20180002. Service information specified in EASA AD 20180002 that is required for compliance with it will be available at https www.regulations.gov by searching for and locating Docket No.
FAA20210505 after the FAA final rule is published.
Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 128
helicopters of U.S. registry. The FAA
estimates the following costs to comply with this proposed AD:

ESTIMATED COSTS FOR REQUIRED ACTIONS
Action
Labor cost
Software upgrade

24 work-hours $85 per hour = $2,040

The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some or all of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected operators.

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.

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.
