Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2021-0238, dated November 2, 2021 
(EASA AD 2021-0238), to correct an unsafe condition for Leonardo 
S.p.a., formerly Finmeccanica S.p.A., AgustaWestland S.p.A., Model 
AW169 helicopters, serial numbers (S/N) from 69006 up to 69125 
inclusive, except S/N 69040; and S/N 69130, 69132, 69133, 69134, 69136, 
and 69139.
    This proposed AD was prompted by a report of a blockage in a fuel 
tank vent line. The FAA is proposing this AD to detect and address the 
blockage, which

[[Page 15895]]

if not addressed, could result in dual engine flameout due to fuel 
starvation and a subsequent forced landing. See EASA AD 2021-0238 for 
additional background information.

Related Service Information Under 1 CFR Part 51

    EASA AD 2021-0238 requires a one-time inspection of the fuel tank 
vent lines and, depending on findings, accomplishment of applicable 
corrective action(s).
    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 Helicopters Alert Service Bulletin 
No. 169-205, dated September 20, 2021. This service information 
specifies procedures for a one-off boroscopic inspection of the right 
and left fuel tank vent lines.

FAA's Determination

    These helicopters have been approved by EASA and are approved for 
operation in the United States. Pursuant to the FAA's 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 the same type design.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified 
in EASA AD 2021-0238, 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 FAA's 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 2021-0238 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2021-0238 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 2021-0238 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 Action(s) and Compliance Time(s)'' in EASA AD 2021-
0238. Service information referenced in EASA AD 2021-0238 for 
compliance will be available at https://www.regulations.gov by 
searching for and locating Docket No. FAA-2022-0282 after the FAA final 
rule is published.

Differences Between This Proposed AD and the EASA AD

    EASA AD 2021-0238 states to remove the sealant obstructions in 
accordance with the instructions of the service information and to 
contact Leonardo for approved corrective actions instructions and 
accomplishing those instructions within the compliance time specified 
therein; whereas, this proposed AD would require repair done before 
further flight in accordance with a method approved by the Manager, 
General Aviation and Rotorcraft Section, International Validation 
Branch, FAA; or EASA; or Leonardo S.p.a. Helicopters' EASA Design 
Organization Approval (DOA). If approved by the DOA, the approval must 
include the DOA-authorized signature.
    EASA AD 2021-0238 states to inspect the fuel tank vent lines in 
accordance with the instructions of the service information, which 
specifies inspecting for evidence of a partial or total Proseal 
obstruction. This proposed AD would require inspecting for a partial or 
total Proseal obstruction.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 6 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.
    Boroscopic inspecting the fuel tank vent lines would take 
approximately 6 work-hours for an estimated cost of $510 per helicopter 
and up to $3,060 for the U.S. fleet. The FAA has no way of knowing the 
cost to repair a fuel tank vent line.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's 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 Agency's 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.
