[USCG-2013-0718]
RIN 1625-AA08

Special Local Regulation, Cumberland River, Mile 157.0 to 159.0;
Ashland City, TN

AGENCY: Coast Guard, DHS.

ACTION: Temporary final rule.

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

SUMMARY: The Coast Guard is establishing a temporary special local
regulation for the waters of the Cumberland River beginning at mile
marker 157.0 and ending at mile marker 159.0, extending bank to bank.
This zone is necessary to protect the swimmers participating in the
Nashvegas Triathlon on the Cumberland River. Entry into this area is
prohibited unless specifically authorized by the Captain of the Port
(COTP) Ohio Valley or designated representative.

DATES: This rule is effective from 6:00 a.m. to 11:30 a.m. September 7,
2013.

ADDRESSES: Documents mentioned in this preamble are part of docket
[USCG-2013-0718]. To view documents mentioned in this preamble as being

SUPPLEMENTARY INFORMATION:

COTP Captain of the Port

FR Federal Register
NPRM Notice of Proposed Rulemaking

A. Regulatory History and Information

    The Coast Guard is issuing this temporary final rule without prior
notice and opportunity to comment pursuant to authority under section
4(a) of the Administrative Procedure Act (APA) (5 U.S.C. 553(b)). This
provision authorizes an agency to issue a rule without prior notice and
opportunity to comment when the agency for good cause finds that those
procedures are ``impracticable, unnecessary, or contrary to the public
interest.'' Under 5 U.S.C. 553(b)(B), the Coast Guard finds that good
cause exists for not publishing a notice of proposed rulemaking (NPRM)
with respect to this rule. The Coast guard received notice on June 28,
2013 that the Nashvegas Triathlon is planned to take place on September
7, 2013. A special local regulation is necessary during a swim event on
the Cumberland River. There is not time to complete the NPRM process,
and immediate action is necessary to establish this special local
regulation to protect participants and event personnel from the
possible marine hazards present during the swim portion of the
triathlon. Delaying the special local regulation would also
unnecessarily interfere with the planned event. This event is included
in an ongoing rulemaking to be added to the CFR that can be found under
docket number USCG-2013-0014.
    For the same reasons, under 5 U.S.C. 553(d)(3), the Coast Guard
finds that good cause exists for making this rule effective less than
30 days after publication in the Federal Register. Providing a full 30
days notice and delaying the effective date for this special local
regulation would be impracticable because immediate action is necessary
to protect event participants from the possible marine hazards present
during the triathlon.

B. Basis and Purpose

    The Nashvegas Triathlon takes place on the Cumberland River from
mile marker 157.0 to 159.0. The Coast Guard determined that a temporary
special local regulation is needed to protect the 800 swimmers
participating in the Nashvegas Triathlon. The legal basis and
authorities for this rulemaking establishing a special local regulation
are found in 33 U.S.C. 1233, which authorize the Coast Guard to
establish and define special local regulations. The COTP Ohio Valley is
establishing a special local regulation for the waters of the
Cumberland River, beginning at mile marker 157.0 and ending at 159.0 to
protect the swimmers participating in the Nashvegas Triathlon. Entry
into this area is prohibited unless specifically authorized by the COTP
Ohio Valley or designated representative.

C. Discussion of the Final Rule

    The COTP Ohio Valley is establishing a special local regulation for
the waters of the Cumberland River, beginning at mile marker 157.0 and
ending at 159.0, during the swim portion of the Nashvegas Triathlon.
During this event, vessels shall not enter into, depart from, or move
within the area of this special local regulation without permission
from the COTP Ohio Valley or his authorized representative. Persons or
vessels requiring entry into or passage through the special local
regulation must request permission from the COTP Ohio Valley, or a
designated representative. They may be contacted on VHF-FM Channel 13
or 16, or through Coast Guard Sector Ohio Valley at 1-800-253-7465.
This rule is effective from 6:00 a.m. to 11:30 a.m. September 7, 2013.
The COTP Ohio Valley will inform the public through Broadcast Notices
to Mariners (BNM) of the enforcement period for the special local
regulation as well as any changes in the planned schedule.

D. Regulatory Analyses

    We developed this rule after considering numerous statutes and
executive orders related to rulemaking. Below we summarize our analyses
based on a number of these statutes or executive orders.

1. Regulatory Planning and Review

    This rule is not a significant regulatory action under section 3(f)
of Executive Order 12866, Regulatory Planning and Review, as
supplemented by Executive Order 13563, Improving Regulation and
Regulatory Review, and does not require an assessment of potential
costs and benefits under section 6(a)(3) of Executive Order 12866 or
under section 1 of Executive Order 13563. The Office of Management and
Budget has not reviewed it under that Order.
    This special local regulation restricts transit on the Cumberland
River from mile marker 157.0 through 159.0 and covers a period of five
and one half hours, from 6:00 a.m. to 11:30 a.m. September 7, 2013. Due
to its short duration and limited scope, it does not pose a significant
regulatory impact. Broadcast Notices to Mariners (BNM) will also inform
the community of this special local regulation so that they may plan
accordingly for this short restriction on transit. Vessel traffic may
request permission from the COTP Ohio Valley or a designated
representative to enter the restricted area.

2. Impact on Small Entities

    The Regulatory Flexibility Act of 1980 (RFA), 5 U.S.C. 601-612, as
amended, requires federal agencies to consider the potential impact of
regulations on small entities during rulemaking. The Coast Guard
certifies under 5 U.S.C. 605(b) that this rule will not have a
significant economic impact on a substantial number of small entities.
    This rule will affect the following entities, some of which may be
small entities: The owners or operators of vessels intending to transit
mile marker 157.0 to 159.0 on the Cumberland River, from 6:00 a.m. to
11:30 a.m. on September 7, 2013. The special local regulation will not
have a significant economic impact on a substantial number of small
entities because this rule will be in effect for a short period of
time. BNMs will also inform the community of this special local
regulation so that they may plan accordingly for this short restriction
on transit. Vessel traffic may request permission from the COTP Ohio
Valley or a designated representative to enter the restricted area.

3. Assistance for Small Entities

    Under section 213(a) of the Small Business Regulatory Enforcement
Fairness Act of 1996 (Pub. L. 104-121), we want to assist small
entities in understanding this rule. If the rule would affect your
small business, organization, or governmental jurisdiction and you have
questions concerning its provisions or options for compliance, please
contact the person listed in the FOR FURTHER INFORMATION CONTACT,
above.
    Small businesses may send comments on the actions of Federal
employees

who enforce, or otherwise determine compliance with, Federal
regulations to the Small Business and Agriculture Regulatory
Enforcement Ombudsman and the Regional Small Business Regulatory
Fairness Boards. The Ombudsman evaluates these actions annually and
rates each agency's responsiveness to small business. If you wish to
comment on actions by employees of the Coast Guard, call 1-888-REG-FAIR
(1-888-734-3247). The Coast Guard will not retaliate against small
entities that question or complain about this rule or any policy or
action of the Coast Guard.

4. Collection of Information

    This rule will not call for a new collection of information under
the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520).

5. Federalism

    A rule has implications for federalism under Executive Order 13132,
Federalism, if it has 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. We have analyzed this rule under that Order and determined
that this rule does not have implications for federalism.

6. Protest Activities

    The Coast Guard respects the First Amendment rights of protesters.
Protesters are asked to contact the person listed in the FOR FURTHER
INFORMATION CONTACT section to coordinate protest activities so that
your message can be received without jeopardizing the safety or
security of people, places or vessels.

7. Unfunded Mandates Reform Act

    The Unfunded Mandates Reform Act of 1995 (2 U.S.C. 1531-1538)
requires Federal agencies to assess the effects of their discretionary
regulatory actions. In particular, the Act addresses actions that may
result in the expenditure by a State, local, or tribal government, in
the aggregate, or by the private sector of $100,000,000 (adjusted for
inflation) or more in any one year. Though this rule will not result in
such expenditure, we do discuss the effects of this rule elsewhere in
this preamble.

8. Taking of Private Property

    This rule will not cause a taking of private property or otherwise
have taking implications under Executive Order 12630, Governmental
Actions and Interference with Constitutionally Protected Property
Rights.

9. Civil Justice Reform

    This rule meets applicable standards in sections 3(a) and 3(b)(2)
of Executive Order 12988, Civil Justice Reform, to minimize litigation,
eliminate ambiguity, and reduce burden.

10. Protection of Children

    We have analyzed this rule under Executive Order 13045, Protection
of Children from Environmental Health Risks and Safety Risks. This rule
is not an economically significant rule and does not create an
environmental risk to health or risk to safety that may
disproportionately affect children.

11. Indian Tribal Governments

    This rule does not have tribal implications under Executive Order
13175, Consultation and Coordination with Indian Tribal Governments,
because it does not have a substantial direct effect on one or more
Indian tribes, on the relationship between the Federal Government and
Indian tribes, or on the distribution of power and responsibilities
between the Federal Government and Indian tribes.

12. Energy Effects

    This action is not a ``significant energy action'' under Executive
Order 13211, Actions Concerning Regulations That Significantly Affect
Energy Supply, Distribution, or Use.

13. Technical Standards

    This rule does not use technical standards. Therefore, we did not
consider the use of voluntary consensus standards.

14. Environment

    We have analyzed this rule under Department of Homeland Security
Management Directive 023-01 and Commandant Instruction M16475.lD, which
guide the Coast Guard in complying with the National Environmental
Policy Act of 1969 (NEPA) (42 U.S.C. 4321-4370f), and have concluded
this action is one of a category of actions that do not individually or
cumulatively have a significant effect on the human environment. This
rule is categorically excluded, under figure 2-1, paragraph (34)(h), of
the Instruction. This rule involves establishing a temporary special
local regulation to protect the swimmers participating in the Nashvegas
Triathlon on the Cumberland River from mile markers 157.0 to 159.0 for
five hour period on one day.
    An environmental analysis was performed during the marine event
permit process for the triathlon event and a checklist and a
categorical exclusion determination are not required for this special
local regulation.

SUPPLEMENTARY INFORMATION: The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would
apply to Airbus Helicopters Model AS-365N2, AS 365 N3, SA-365N, and SA-
365N1 helicopters, with at least one Type X or Y planet gear assembly
with a serial number (S/N) listed in Appendices 4.A. through 4.B of
Airbus Helicopters Alert Service Bulletin ASB No. AS365-05.00.78,
Revision 3, dated March 2, 2018 (ASB AS365-05.00.78), installed on the
MGB. The NPRM published in the Federal Register on August 7, 2020 (85
FR 47925). In the NPRM, the FAA proposed to require replacing the MGB
before further flight for helicopters with a Type X planet gear
assembly with a certain S/N installed. The NPRM also proposed to
require, for helicopters with no Type X planet gear assembly installed
but at least one Type Y planet gear assembly with a certain S/N
installed, replacing the MGB within 300 hours time-in-service (TIS) or
before any planet gear assembly accumulates 1,300 hours TIS since new,
whichever occurs first. As an alternative to replacing the MGB, the
NPRM proposed to allow replacing the epicyclic reduction gear module in
the affected MGB.
    The NPRM also proposed to prohibit installing an MGB with Type Y or
Type X planet gear assembly installed on any helicopter. Finally, the
NPRM proposed to require, within 10 hours TIS and thereafter before the
first flight of the day or at intervals not to exceed 10 hours TIS,
whichever occurs first, inspecting the lower MGB magnetic plugs for
particles. If there are particles, the NPRM proposed to require
replacing the MGB depending on the type and the size of particles. The
NPRM was prompted by EASA AD 2017-0116, Revision 2, dated March 2,
2018, (EASA AD 2017-01162R2), issued by EASA, which is the Technical
Agent for the Member States of the European Union, to correct an unsafe
condition for Airbus Helicopters Model AS 365 N2, AS 365 N3, SA 365 N,
and SA 365 N1 helicopters. EASA advises that after an accident on a
Model EC225 helicopter, an investigation revealed the failure of a
second stage planet gear of the MGB. EASA states that one of the two
types of planet gear assemblies used in the MGB epicyclic module is
subject to higher outer race contact pressures and therefore is more
susceptible to spalling and cracking. Airbus Helicopters reviewed its
range of helicopters with regard to this issue and provided
instructions to improve the reliability of the installed MGB.
    Accordingly, EASA AD 2017-01162R2 requires repetitive inspections
of the MGB magnetic plugs and corrective action if any particles are
detected. EASA AD 2017-01162R2 also requires, if certain MGB planet
gear assemblies are installed, replacing the planet gear assemblies.
Finally, EASA AD 2017-01162R2 prohibits installing an MGB with a Type X
or Type Y planet gear assembly on any helicopter.
    After the NPRM was issued, the FAA discovered that the proposed
applicability was limited to helicopters with at least one affected
assembly installed on the MGB, whereas all Airbus Helicopters Model AS-
365N2, AS 365 N3, SA-365N, and SA-365N1 helicopters, regardless of the
assembly, are subject to the unsafe condition and require repetitive
inspections of the MGB magnetic plugs for particles. The FAA also
determined that any special flight permits would be limited to flights
with no passengers on board.
    Therefore, the FAA issued a supplemental notice of proposed
rulemaking (SNPRM) to amend 14 CFR part 39 by adding an AD that would
apply to all Airbus Helicopters Model AS-365N2, AS 365 N3, SA-365N, and
SA-365N1 helicopters. The SNPRM published in the Federal Register on
March 22, 2021 (86 FR 15143). The SNPRM maintained the proposed
corrective actions from the NPRM as follows, but no longer limited the
applicability to only certain helicopters:
     Before further flight, for helicopters with a Type X
planet gear assembly with a certain S/N installed, replacing the MGB.
     For helicopters with no Type X planet gear assembly
installed but at least one Type Y planet gear assembly with a certain
S/N installed, replacing the MGB within 300 hours TIS or before any
planet gear assembly accumulates 1,300 hours TIS since new, whichever
occurs first.
     As an alternative to replacing the MGB, the SNPRM proposed
to allow

replacing the epicyclic reduction gear module in the affected MGB.
    The SNPRM also proposed to:
     Prohibit installing an MGB with Type Y or Type X planet
gear assembly installed on any helicopter.
     Require, within 10 hours TIS and thereafter before the
first flight of the day or at intervals not to exceed 10 hours TIS,
whichever occurs first, inspecting the lower MGB magnetic plugs for
particles and, if there are particles, replacing the MGB, depending on
the type and the size of those particles.

Discussion of Final Airworthiness Directive

Comments

    The FAA received no comments on the SNPRM or on the determination
of the costs.

Conclusion

    The helicopters 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.

Related Service Information Under 1 CFR Part 51

    Airbus Helicopters has issued ASB AS365-05.00.78 for Model SA-365N,
SA-365N1, AS-365N2, and AS 365 N3 helicopters. This service information
specifies performing periodic inspections of the MGB magnetic plugs for
particles. This service information also specifies identifying the type
of gear assembly installed in the MGB and replacing any Type X assembly
within 50 hours TIS. For Type Y gear assemblies, the service
information requires replacing the assembly within 50 hours TIS or
within 300 hours TIS, depending on the time since new. The service
information specifies Type Z gear assemblies should be left as is.
    Airbus Helicopters has also issued Service Bulletin SB No. AS365-
63.00.21, Revision 3, dated July 26, 2018, for Model AS365 helicopters.
This service information contains procedures for replacing the MGB
epicyclic reduction gear as an option to replacing the MGB.
    This service information 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 EASA AD

    The EASA AD requires a 50-hour or 300-hour TIS compliance time or
by June 30, 2019, whichever occurs first, to determine the type of
planet gear installed in the MGB, and depending on the outcome, to
replace the MGB; the compliance time for this AD is based only on hours
TIS or before further flight. The EASA AD allows a pilot to inspect the
MGB magnetic plugs for particles; this AD does not.

Costs of Compliance

    The FAA estimates that this AD affects 34 helicopters of U.S.
Registry and that operators may incur the following costs in order to
comply with this AD. Labor costs are estimated at $85 per work-hour.
    Inspecting the magnetic plugs and oil filter for particle deposits
will take about 1 work-hour for an estimated cost of $85 per helicopter
per inspection cycle.
    Replacing an MGB will take about 42 work-hours for cost of $3,570
and parts will cost about $295,000 (overhauled) for a total cost of
$298,570 per helicopter.
    Replacing the epicyclic reduction gear will take about 56 work-
hours for an estimated cost of $4,760 and parts will cost about $11,404
for a total cost of $16,164 per helicopter.

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 helicopters 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.
