Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2020-0281, dated December 16, 2020 
(EASA AD 2020-0281), to correct an unsafe condition for certain serial-
numbered Airbus Helicopters (AH), formerly Eurocopter, Eurocopter 
France, Aerospatiale Model AS 332 L2 and EC 225 LP helicopters.
    This proposed AD was prompted by a design deficiency involving the 
incorrect wiring routing of the electrical hoist installation. The 
affected wiring was not protected by the circuit breaker that was 
intended to provide electrical protection for that wiring. The FAA is 
proposing this AD to correct the electrical hoist installation wiring 
routing. See EASA AD 2020-0281 for additional background information.

Related Service Information Under 1 CFR Part 51

    EASA AD 2020-0281 requires modifying the hoist control power 
supply.
    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.

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 these same type designs.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified 
in EASA AD 2020-0281, described previously, as incorporated by 
reference, except for any differences identified as exceptions in the 
regulatory text of this proposed 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 2020-0281 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2020-0281 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 2020-0281 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 2020-
0281. Service information required by EASA AD 2020-0281 for compliance 
will be available at https://www.regulations.gov by searching for and 
locating Docket No. FAA-2021-0693 after the FAA final rule is 
published.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 5 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.
    Modifying the electrical hoist control power supply would take 
about 4 work-hours and parts would cost about $10, for an estimated 
cost of $350 per helicopter and $1,750 for the affected U.S. fleet.

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.

[[Page 47422]]

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.
