Federal Register / Vol. 86, No. 171 / Wednesday, September 8, 2021 / Proposed Rules
hydraulic pump P/N 109076042103
is not eligible for installation on Model AW109SP helicopters, applicable instructions for continued airworthiness are not available. The FAA is proposing this AD to address the ineligible installation of the affected partnumbered hydraulic pump on Model AW109SP helicopters since there are no applicable instructions for continuing airworthiness available. See EASA AD
20190213 for additional background information.
Related Service Information Under 1
CFR Part 51
EASA AD 20190213 requires inspecting each affected hydraulic pump and depending on the inspection results, replacing an affected hydraulic pump with a serviceable hydraulic pump, before further flight. EASA AD
20190213 also requires replacing any affected hydraulic pump before exceeding 1,600 total flight hours FH
since first installation on a helicopter, or within 200 FH, whichever occurs later.
Finally, EASA AD 20190213 prohibits installing any affected hydraulic pump on any helicopter.
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.
Other Related Service Information The FAA also reviewed Leonardo S.p.a. Helicopters, Alert Service Bulletin No. 109SP134, dated July 29, 2019.
This service information specifies procedures for inspecting and replacing hydraulic pump P/N 109076042103.

FAAs Determination These helicopters have been approved by EASA and are approved for operation in the United States. Pursuant to the FAAs bilateral agreement with the European Union, EASA has notified the FAA about the unsafe condition described in its AD. The FAA is proposing this AD after evaluating all known relevant information and determining that the unsafe condition described previously is likely to exist or develop on other helicopters of these same type designs.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified in EASA AD 20190213, described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this proposed AD and except as discussed under Differences

Between this Proposed AD and the EASA 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 20190213 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 20190213
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 20190213 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 20190213.
Service information required by EASA
AD 20190213 for compliance will be available at https www.regulations.gov by searching for and locating Docket No.
FAA20210720 after the FAA final rule is published.
Differences Between This Proposed AD
and EASA AD 20190213
EASA AD 20190213 applies to Model AW109SP helicopters, all serial numbers, whereas this proposed AD
would only apply to Model AW109SP
helicopters with certain part-numbered hydraulic pumps installed.
Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 17
helicopters of U.S. Registry. Labor rates are estimated at $85 per work-hour.
Based on these numbers, the FAA
estimates the following costs to comply with this proposed AD.
Visually inspecting each hydraulic pump for wear, burrs, and abrasion would take about 4 work-hours and parts would cost about $5 for an estimated cost of $345 per inspection and $5,865 for the U.S. fleet.
Removing from service each affected hydraulic pump and replacing with an airworthy hydraulic pump would take about 6 work-hours and parts would

cost about $22,819 for an estimated cost of $23,329 per pump replacement.
The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some 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.
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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.
The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
