Airworthiness Directives; Airbus Helicopters
Publication summary
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model AS355NP helicopters. This 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 AD requires 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 incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

Unsafe Condition
(e) Unsafe Condition
This 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.

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all
Airbus Helicopters Model AS355NP helicopters. This 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 AD requires 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 incorporated
by reference. The FAA is issuing this AD to address the unsafe
condition on these products.
DATES: This AD is effective January 13, 2022.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of January 13,
2022.

SUPPLEMENTARY INFORMATION:
Background
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.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to all Airbus Helicopters
Model AS355NP helicopters. The NPRM published in the Federal Register
on September 23, 2021 (86 FR 52853). The NPRM 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. The NPRM proposed to require replacement of the
protective cover of the ``SHEAR'' control pushbutton, and re-
identification of the pilot collective stick, as specified in EASA AD
2021-0027R1.
The FAA is issuing 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.
Discussion of Final Airworthiness Directive
Comments
The FAA received no comments on the NPRM or on the determination of
the costs.
Conclusion
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 reviewed the relevant
data and determined that air safety requires adopting this AD as
proposed. Accordingly, the FAA is issuing this AD to address the unsafe
condition on these helicopters. Except for minor editorial changes,
this AD is adopted as proposed in the NPRM.
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.
Costs of Compliance
The FAA estimates that this AD affects 2 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 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 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
This AD will not have federalism implications under Executive Order
13132. This AD will 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 that this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Will not affect intrastate aviation in Alaska, and
(3) Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
