14 CFR Part 39

[Docket No. FAA-2020-1119; Project Identifier 2019-SW-089-AD; Amendment 
39-21484; AD 2021-07-07]

Airworthiness Directives; Airbus Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all 
Airbus Helicopters Model EC 155B and EC155B1 helicopters. This AD was 
prompted by a report of mechanical deformation of the protective cover 
of the ``SHEAR'' control pushbutton on the copilot collective stick. 
This AD requires replacement of the protective cover of the ``SHEAR'' 
control pushbutton on the pilot and copilot collective sticks and re-
identification of the pilot and copilot collective sticks, 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 May 10, 2021.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of May 10, 
2021.

SUPPLEMENTARY INFORMATION:

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2019-0246, dated October 1, 2019 
(EASA AD 2019-0246) (also referred to as the Mandatory Continuing 
Airworthiness Information, or the MCAI), to correct an unsafe condition 
for all Airbus Helicopters Model EC 155B and EC155B1 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 EC 155B and EC155B1 helicopters. The NPRM published in the 
Federal Register on January 15, 2021 (86 FR 3883). The NPRM was 
prompted by a report of mechanical deformation of the protective cover 
of the ``SHEAR'' control pushbutton on the copilot collective stick. 
The NPRM proposed to require replacement of the protective cover of the 
``SHEAR'' control pushbutton on the pilot and copilot collective sticks 
and re-identification of the pilot and copilot collective sticks, as 
specified in an EASA AD.
    The FAA is issuing this AD to address mechanical deformation of the 
protective cover of the ``SHEAR'' control pushbutton on the copilot 
collective stick, which could lead to uncommanded shearing of the hoist 
cable and possible injury to hoisted person(s). See the MCAI for 
additional background information.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The FAA received no comments on the NPRM or 
on the determination of the cost to the public.

Conclusion

    The FAA reviewed the relevant data and determined that air safety 
and the public interest require adopting this final rule as proposed, 
except for minor

[[Page 17511]]

editorial changes. The FAA has determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    EASA AD 2019-0246 describes procedures for replacement of the 
protective cover of the ``SHEAR'' control pushbutton on the pilot and 
copilot collective sticks and re-identification of the pilot and 
copilot collective sticks. 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.

Differences Between This AD and the MCAI

    Where paragraph (1) of EASA AD 2019-0246 refers to a table for the 
compliance time for the modification, for this AD, the compliance time 
for the modification is before any hoist operations after the effective 
date of this AD but no later than 3 months after the effective date of 
this AD.

Costs of Compliance

    The FAA estimates that this AD affects 17 helicopters of U.S. 
registry. 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...........................          $2,446           $2,616          $44,472
----------------------------------------------------------------------------------------------------------------

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

(i) Special Flight Permit

    Special flight permits may be issued in accordance with 14 CFR 
21.197 and 21.199 to operate the helicopter to a location where the 
helicopter can be modified (if the operator elects to do so), 
provided the helicopter is not used for hoist operations and no 
passengers are onboard.

    (1) The Manager, International Validation Branch, FAA, has the 
authority to approve AMOCs for this AD, if requested using the
