Drawbridge Operation Regulation; Chehalis River, Aberdeen, WA,
Schedule Change

AGENCY: Coast Guard, DHS.

ACTION: Final rule.

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

SUMMARY: The Coast Guard is changing the regulations that govern the
operation of the U.S. Highway 101 bascule bridge across the Chehalis
River, mile 0.1, at Aberdeen, Washington. At least one-hour notice by
telephone will be required at all times for draw openings. The change
is necessary to allow the bridge owner to reduce the staffing
requirements of the bridge in light of the infrequent openings
requested for the bridge.

SUPPLEMENTARY INFORMATION:

Regulatory Information

    On December 4, 2009, we published a notice of proposed rulemaking
(NPRM) entitled Drawbridge Operation Regulations; Chehalis River,
Aberdeen, WA, Schedule Change in the Federal Register (74 FR 63695). We
received no comments on the proposed rule. No public meeting was
requested and none was held.

Background and Purpose

    This rule enables the Washington State Department of
Transportation, the owner of the Chehalis River Bridge, to operate the
draw only if at least one-hour notice is provided at all times. This
notice will be given by telephone to<PHONE_NUMBER>. A marine radio will
also be maintained at the bridge, but will only be monitored when a
draw tender is present. Previously, one-hour notice was only required
between 9 p.m. and 5 a.m.
    Over the years ship traffic has dwindled on this reach of the
Chehalis River. From June through September 2009 the draw did not open
for large oceangoing vessels. The former ship traffic is now focused
seaward of the bridge following the recent closure of timber terminals
above the bridge. The bridge averages only seven openings a month
during those daylight hours when a draw operator is present. The
Washington State Department of Transportation requested this change to
reduce unnecessary staffing of the drawbridge in light of the
infrequent openings requested for the bridge.

Discussion of Comments and Changes

    No comments were received on the proposed rule and no changes were
made to the proposed rule.

Regulatory Analyses

    We developed this rule after considering numerous statutes and
executive orders related to rulemaking. Below we summarize our analyses
based on 13 of these statutes or executive orders.

Regulatory Planning and Review

    This rule is not a significant regulatory action under section 3(f)
of Executive Order 12866, Regulatory Planning and Review, and does not
require an assessment of potential costs and benefits under section
6(a)(3) of that Order. The Office of Management and Budget has not
reviewed it under that Order. The Coast Guard has made this
determination based on the fact that vessel operators will not be
significantly impacted since they will still be able to transit under
the bridge by giving one-hour notice.

Small Entities

    Under the Regulatory Flexibility Act (5 U.S.C. 601-612), we have
considered whether this rule would have a significant economic impact
on a substantial number of small entities. The term ``small entities''
comprises small businesses, not-for-profit organizations that are
independently owned and operated and are not dominant in their fields,
and governmental jurisdictions with populations of less than 50,000.
    The Coast Guard certifies under 5 U.S.C. 605(b) that this rule
would not have a significant economic impact on a substantial number of
small entities because all vessel operators will not be significantly
impacted since they will still be able to transit under the bridge by
giving one-hour notice.

Assistance for Small Entities

    Under section 213(a) of the Small Business Regulatory Enforcement
Fairness Act of 1996 (Pub. L. 104-121), in the NPRM we offered to
assist small entities in understanding this rule so that they can
better evaluate its effects on them and participate in the rulemaking
process.
    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.

Collection of Information

    This rule calls for no new collection of information under the
Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520.).

Federalism

    A rule has implications for federalism under Executive Order 13132,
Federalism, if it has a substantial direct effect on State or local
governments and would either preempt State law or impose a substantial
direct cost of compliance on them. We have analyzed this rule under
that Order and have determined that it does not have implications for
federalism.

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 or more in any
one year. Though this rule will not result in such an expenditure, we
do discuss the effects of this rule elsewhere in this preamble.

Taking of Private Property

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

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.

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 would not create an
environmental risk to health or risk to safety that might
disproportionately affect children.

Indian Tribal Governments

    This rule does not have tribal implications under Executive Order
13175, Consultation and Coordination with Indian Tribal Governments,
because it would 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.

Energy Effects

    We have analyzed this rule under Executive Order 13211, Actions
Concerning Regulations That

Significantly Affect Energy Supply, Distribution, or Use. We have
determined that it is not a ``significant energy action'' under that
order because it is not a ``significant regulatory action'' under
Executive Order 12866 and is not likely to have a significant adverse
effect on the supply, distribution, or use of energy. The Administrator
of Information and Regulatory Affairs has not designated this as a
significant energy action. Therefore, it does not require a Statement
of Energy Effects under Executive Order 13211.

Technical Standards

    The National Technology Transfer and Advancement Act (NTTAA) (15
U.S.C. 272 note) directs agencies to use voluntary consensus standards
in their regulatory activities unless the agency provides Congress,
through the Office of Management and Budget, with an explanation of why
using these standards would be inconsistent with applicable law or
otherwise impractical. Voluntary consensus standards are technical
standards (e.g., specifications of materials, performance, design, or
operation; test methods; sampling procedures; and related management
systems practices) that are developed or adopted by voluntary consensus
standards bodies.
    This rule does not use technical standards. Therefore, we did not
consider the use of voluntary consensus standards.

Environment

    We have analyzed this rule under Department of Homeland Security
Management Directive 023-01, and Commandant Instruction M16475.lD,
which guides the Coast Guard in complying with the National
Environmental Policy Act of 1969 (NEPA) (42 U.S.C. 4321-4370f), and
have concluded that this action is one of a category of actions which
do not individually or cumulatively have a significant effect on the
human environment. This rule is categorically excluded, under figure 2-
1, paragraph (32)(e), of the Instruction.
    Under figure 2-1, paragraph (32)(e), of the Instruction, an
environmental analysis checklist and a categorical exclusion
determination are not required.

Airworthiness Directives; Bombardier, Inc., Airplanes

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 Bombardier, Inc., CL-600-2B16 (604 Variant) airplanes. This
proposed AD was prompted by multiple reports of cracking of the main
landing gear (MLG) shock strut lower pin. This proposed AD would
require repetitive lubrication and repetitive detailed visual
inspections (DVI) and non-destructive test (NDT) inspections of the MLG
shock strut lower pins, and replacement if necessary. 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 July 29,
2021.

794-5531; email<EMAIL_ADDRESS>Any commentary that the FAA
receives which is not specifically designated as CBI will be placed in
the public docket for this rulemaking.

Background

    Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued TCCA AD CF-2020-54R1, dated December
23, 2020 (TCCA AD CF-2020-54R1) (also referred to after this as the
Mandatory Continuing Airworthiness Information, or the MCAI), to
correct an unsafe condition for certain Bombardier, Inc., CL-600-2B16
(604 Variant) airplanes. You may examine the MCAI in the AD docket at
https://www.regulations.gov by searching for and locating Docket No.
FAA-2021-0462.
    This proposed AD was prompted by multiple reports of cracking of
the MLG shock strut lower pin part number (P/N) 19146-3. The subsequent
investigation concluded that the friction torque when the shock strut
is under compression loading, causes the pin anti-rotation tangs to
become loaded beyond their load carrying capability. This overload
condition can result in pin fracture originating at the base of the pin
anti-rotation tang. Inadequate lubrication aggravates the condition.
The FAA is proposing this AD to address cracking of the MLG shock strut
lower pin. If not addressed, this condition could result in structural
failure of one or both MLG. See the MCAI for additional background
information.

Related Service Information Under 1 CFR Part 51

    Bombardier, Inc., has issued the following service information:
     Service Bulletin 604-32-030, dated June 30, 2020.
     Service Bulletin 605-32-007, dated June 30, 2020.
     Service Bulletin 650-32-004, dated June 30, 2020.
    This service information describes procedures for lubricating,
inspecting (DVI and NDT inspections for cracking and damage, including
fracture of the MLG shock strut lower pin at the pin rotation tang
location), and replacing the MLG shock strut lower pin. These documents
are distinct since they apply to different airplane configurations.
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.

FAA's Determination

    This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to the FAA's bilateral agreement with the State of Design Authority,
the FAA has been notified of the unsafe condition

described in the MCAI and service information 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 on other products of the same type design.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified
in the service information already described.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would
affect 433 airplanes 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
----------------------------------------------------------------------------------------------------------------
7 work-hours x $85 per hour = $595...........................              $0             $595         $257,635
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of any
required actions. The FAA has no way of determining the number of
aircraft that might need these on-condition actions:

                 Estimated costs of on-condition actions
------------------------------------------------------------------------
                                                             Cost per
              Labor cost                   Parts cost        product
------------------------------------------------------------------------
6 work-hours x $85 per hour = $510....          $2,435           $2,945
------------------------------------------------------------------------

    The FAA has included all known costs in its cost estimate.
According to the manufacturer, however, some or all of the costs of
this proposed AD may be covered under warranty, thereby reducing the
cost impact on affected operators.

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) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
