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 certain Airbus Helicopters Model SA-365N, SA-365N1, AS-365N2, AS 
365 N3, EC 155B, and EC155B1 helicopters. This proposed AD was prompted 
by the FAA's determination that to improve the process and performance 
in collecting metal particles in the main gear box (MGB) certain 
existing magnetic plugs (electrical and non-electrical) installed in 
the MGB pump intake must be replaced with improved non-electrical 
magnetic plugs. This proposed AD would require replacing the existing 
magnetic plug with an improved non-electrical magnetic plug, as 
specified in a European Aviation Safety Agency (now 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 January 14, 
2021.

the following paragraph, and other

[[Page 76496]]

information as described in 14 CFR 11.35, the FAA will post all 
comments received, without change, to https://www.regulations.gov, 
including any personal information you provide. The agency will also 
post a report summarizing each substantive verbal contact received 
about this proposal.

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this NPRM contain commercial 
or financial information that is customarily treated as private, that 
you actually treat as private, and that is relevant or responsive to 
this NPRM, it is important that you clearly designate the submitted 
comments as CBI. Please mark each page of your submission containing 
CBI as ``PROPIN.'' The FAA will treat such marked submissions as 
confidential under the FOIA, and they will not be placed in the public 
docket of this NPRM. Submissions containing CBI should be sent to 
Mahmood Shah, Aviation Safety Engineer, Fort Worth ACO Branch, FAA, 
10101 Hillwood Pkwy., Fort Worth, TX 76177; telephone 817-222-5538;

is not specifically designated as CBI will be placed in the public 
docket for this rulemaking.

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2018-0176, dated August 21, 2018 
(EASA AD 2018-0176) (also referred to as the Mandatory Continuing 
Airworthiness Information, or the MCAI), to correct an unsafe condition 
for certain Airbus Helicopters Model SA-365N, SA-365N1, AS-365N2, AS 
365 N3, EC 155B, and EC155B1 helicopters.
    This proposed AD was prompted by the FAA's determination that to 
improve the process and performance in collecting metal particles in 
the MGB certain existing magnetic plugs (electrical and non-electrical) 
installed in the MGB pump intake should be replaced with improved non-
electrical magnetic plugs. The FAA is proposing this AD to address 
metal particles causing seizure of the MGB, loss of power to the main 
rotor, and subsequent loss of control of the helicopter. See the MCAI 
for additional background information.

Related Service Information Under 1 CFR Part 51

    EASA AD 2018-0176 describes procedures for replacing the existing 
magnetic plug (electrical and non-electrical) installed in the MGB pump 
intake with an improved non-electrical magnetic plug. 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 2018-0176, 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 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 2018-0176 
will be incorporated by reference in the FAA final rule. This proposed 
AD would, therefore, require compliance with EASA AD 2018-0176 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 2018-0176 that is required for compliance with EASA AD 2018-
0176 will be available on the internet at https://www.regulations.gov 
by searching for and locating Docket No. FAA-2020-1036 after the FAA 
final rule is published.

Interim Action

    The FAA considers this proposed AD interim action. If final action 
is later identified, the FAA might consider further rulemaking then.

Costs of Compliance

    The FAA estimates that this proposed AD affects 52 helicopters of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
               Labor cost                   Parts cost         Cost per  product        Cost on U.S.  operators
----------------------------------------------------------------------------------------------------------------
Up to 7.5 work-hours x $85 per hour =                $55  Up to $692.50.............  Up to $36,010.
 $637.50.
----------------------------------------------------------------------------------------------------------------

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.

[[Page 76497]]

    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.
