Abstract

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model AS355NP helicopters. This proposed AD was prompted by a report of mechanical deformation found on the protective cover (also referred to as switch guard) of the "SHEAR" control pushbutton installed on a co-pilot collective stick of a Model EC225LP helicopter, caused by incorrect handling; due to having an identical design switch guard installed on the pilot collective stick, Model AS355NP helicopters are also affected. This proposed AD would require replacement of the protective cover of the "SHEAR" control pushbutton, and re-identification of the pilot collective stick, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.

Airworthiness Directives; Airbus Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

[[Page 52854]]


ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for all Airbus Helicopters Model AS355NP helicopters. This proposed AD 
was prompted by a report of mechanical deformation found on the 
protective cover (also referred to as switch guard) of the ``SHEAR'' 
control pushbutton installed on a co-pilot collective stick of a Model 
EC225LP helicopter, caused by incorrect handling; due to having an 
identical design switch guard installed on the pilot collective stick, 
Model AS355NP helicopters are also affected. This proposed AD would 
require replacement of the protective cover of the ``SHEAR'' control 
pushbutton, and re-identification of the pilot collective stick, as 
specified in a European Union Aviation Safety Agency (EASA) AD, which 
is proposed for incorporation by reference (IBR). The FAA is proposing 
this AD to address the unsafe condition on these products.

Background

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2021-0027R1, dated January 22, 2021 
(EASA AD 2021-0027R1), to correct an unsafe condition for all Airbus 
Helicopters (formerly Eurocopter) Model AS355NP helicopters.
    This proposed AD was prompted by a report of mechanical deformation 
found on the protective cover of the ``SHEAR'' control pushbutton 
installed on a co-pilot collective stick of a Model EC225LP helicopter, 
caused by incorrect handling; due to having an identical design switch 
guard installed on the pilot collective stick, Model AS355NP 
helicopters are also affected. The FAA is proposing this AD to address 
mechanical deformation on the protective cover of the ``SHEAR'' control 
pushbutton installed on the pilot collective stick. The unsafe 
condition, if not addressed, could result in unintended shearing of the 
hoist cable, possibly resulting in injury to hoisted person(s). See 
EASA AD 2021-0027R1 for additional background information.
    FAA AD 2020-15-15, Amendment 39-21178 (85 FR 45765, July 30, 2020), 
which was prompted by EASA AD 2018-0106, dated May 10, 2018, addresses 
the unsafe condition for Airbus Helicopters (formerly Eurocopter, 
Eurocopter France, and Aerospatiale) Model EC225LP helicopters.

Related Service Information Under 1 CFR Part 51

    EASA AD 2021-0027R1 requires replacement of the protective cover of 
the ``SHEAR'' control pushbutton, and re-identification of the pilot 
collective stick. 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

[[Page 52855]]

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 2021-0027R1, 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 2021-0027R1 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2021-0027R1 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 2021-0027R1 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-
0027R1. Service information required by EASA AD 2021-0027R1 for 
compliance will be available at <a href="https://www.regulations.gov">https://www.regulations.gov</a> by 
searching for and locating Docket No. FAA-2021-0796 after the FAA final 
rule is published.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 2 helicopters of U.S. registry. Based on these numbers, the FAA 
estimates the following costs to comply with this proposed AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
2 work-hours x $85 per hour = $170...........................            $360             $530           $1,060
----------------------------------------------------------------------------------------------------------------

    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 individuals. The FAA does not control warranty 
coverage for affected individuals. 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 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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

EASA AD 2021-0027R1 is complete.

(j) No Reporting Requirement

    Although the service information referenced in EASA AD 2021-
0027R1 specifies to submit certain information to the manufacturer, 
this AD does not include that requirement.

(k) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, International Validation Branch, FAA, has the 
authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, 
send your request to your principal inspector or local Flight 
Standards District Office, as appropriate. If sending information 
directly to the manager of the International Validation Branch, send
