Airworthiness Directives; Airbus Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for all Airbus Helicopters Model EC 155B and EC155B1 helicopters. This 
proposed AD was prompted by a report of mechanical deformation of the 
protective cover of the ``SHEAR'' control pushbutton on the copilot 
collective stick. This proposed AD would 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 a European Union Aviation 
Safety Agency (EASA) AD, which is proposed for incorporation by 
reference. The FAA is proposing this AD to address the unsafe condition 
on these products.

DATES: The FAA must receive comments on this proposed AD by March 1, 
2021.

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.
    This proposed AD was prompted by a report of mechanical deformation 
of the protective cover of the ``SHEAR'' control pushbutton on the 
copilot collective stick of an EC 225 LP helicopter from incorrect 
handling. The FAA has determined that Model EC

[[Page 3884]]

155B and EC155B1 helicopters are also affected due to an identical 
switch guard design. The FAA is proposing this AD to address mechanical 
deformation of the protective cover of the ``SHEAR'' control pushbutton 
on the copilot collective stick, which could lead to un-commanded 
shearing of the hoist cable and possible injury to hoisted person(s). 
See the MCAI for additional background information.

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.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to the bilateral agreement with the State of Design Authority, the FAA 
has been notified of the unsafe condition described in the MCAI 
referenced above. The FAA is proposing this AD because the FAA 
evaluated all the relevant information and determined the unsafe 
condition described previously is likely to exist or develop in other 
products of the same type design.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in EASA AD 2019-0246, 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 MCAI.''

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA initially worked with Airbus and EASA to develop a 
process to use certain EASA ADs as the primary source of information 
for compliance with requirements for corresponding FAA ADs. The FAA has 
since coordinated with other manufacturers and civil aviation 
authorities (CAAs) to use this process. As a result, EASA AD 2019-0246 
will be incorporated by reference in the FAA final rule. This proposed 
AD would, therefore, require compliance with EASA AD 2019-0246 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 the EASA AD 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 the EASA AD. Service information specified 
in EASA AD 2019-0246 that is required for compliance with EASA AD 2019-
0246 will be available on the internet at https://www.regulations.gov 
by searching for and locating Docket No. FAA-2020-1119 after the FAA 
final rule is published.

Differences Between This Proposed 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 proposed 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 proposed AD affects 17 helicopters of 
U.S. registry. 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...........................          $2,446           $2,616          $44,472
----------------------------------------------------------------------------------------------------------------

    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 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

    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) 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.

for the compliance time for the modification, for this AD, the 
compliance time for the modification is before the first hoist 
operation done after the effective date of this AD but no later than 
3 months after the effective date of this AD.
    (5) Although the service information referenced in EASA 2019-
0246 specifies to discard certain parts, this AD does not include 
that requirement.

(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.
