SUPPLEMENTARY INFORMATION:

Regulatory 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 because immediate action is necessary to
ensure the safety of vessels, spectators, participants, and others in
the vicinity of the marine event on the dates and times this rule will
be in effect and delay would be contrary to the public interest.
    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 because delaying the effective date
would be contrary to the public interest, since immediate action is
needed to ensure the public's safety.

Background and Purpose

    Sea World is sponsoring the Sea World Summer Nights Fireworks,
which will include a fireworks presentation from a barge in Mission
Bay. The safety zone will be a 600 foot radius around the barge in
approximate position 32[deg]46[min]03[sec] N, 117[deg]13[min]11[sec] W.
This temporary safety zone is necessary to provide for the safety of
the crew, spectators, participants, and other vessels and users of the
waterway.

Discussion of Rule

    The Coast Guard is establishing a safety zone that will be enforced
from 8 p.m. to 10 p.m. on June 12, 2009 through August 30, 2009. The
limits of the safety zone will be a 600 foot radius around the barge in
approximate position 32[deg]46'03'' N, 117[deg]13'11'' W. The safety
zone is necessary to provide for the safety of the crew, spectators,
participants, and other vessels and users of the waterway. Persons and
vessels are prohibited from entering into, transiting through, or
anchoring within this safety zone unless authorized by the Captain of
the Port, or his designated representative.

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.
    We expect the economic impact of this rule to be so minimal that a
full Regulatory Evaluation is unnecessary. This determination is based
on the size and location of the safety zone. Commercial vessels will
not be hindered by the safety zone. Recreational vessels will not be
allowed to transit through the designated safety zone during the
specified times.

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 will
not have a significant economic impact on a substantial number of small
entities.
    This rule will not have a significant economic impact on a
substantial number of small entities for the following reasons: Vessel
traffic can pass safely around the safety zone. Before the effective
period, the Coast Guard will publish a local notice to mariners (LNM)
and will issue broadcast notice to mariners (BNM) alerts via marine
channel 16 VHF before the safety zone is enforced.

Assistance for Small Entities

    Under section 213(a) of the Small Business Regulatory Enforcement
Fairness Act of 1996 (Pub. L. 104-121), we offer to assist small
entities in understanding the 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 effect 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 does not create an
environmental risk to health or risk to safety that may
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 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.

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 the Office of Information and
Regulatory Affairs has not designated it 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
guide 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 involves the establishment of a safety zone for
fireworks displays. This rule is categorically excluded, under figure
2-1, paragraph (34)(g), of the Instruction, from further environmental
documentation. An environmental analysis checklist and a categorical
exclusion determination are available in the docket where indicated
under ADDRESSES.

14 CFR Part 39

[Docket No. FAA-2018-0368; Product Identifier 2018-NE-12-AD; Amendment
39-19469; AD 2018-21-11]
RIN 2120-AA64

Airworthiness Directives; Pratt & Whitney Division (PW) Turbofan
Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all
Pratt & Whitney Division (PW) PW4074D, PW4077D, PW4084D, PW4090, and
PW4090-3 turbofan engines with a low-pressure compressor (LPC) fan hub,
part number (P/N) 51B821 or P/N 52B521, installed. This AD was prompted
by updated low-cycle fatigue analysis techniques that indicate certain
LPC fan hubs could crack before their published life limit. This AD
requires repetitive eddy current inspections (ECIs) and fluorescent
penetrant inspections (FPIs) for cracks in certain LPC fan hubs and
removal of LPC fan hubs from service that fail inspection. We are
issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective December 5, 2018.
    The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of December 5,
2018.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to all PW PW4074D, PW4077D,
PW4084D, PW4090, and PW4090-3 turbofan engines with an LPC fan hub, P/N
51B821 or P/N 52B521, installed. The NPRM published in the Federal
Register on July 19, 2018 (83 FR 34070). The NPRM was prompted by
updated low-cycle fatigue analysis techniques that indicate certain LPC
fan hubs could crack before their published life limit. The NPRM
proposed to require repetitive ECIs and FPIs of the LPC fan hub. We are
issuing this AD to address the unsafe condition on these products.

Comments

    We gave the public the opportunity to participate in developing
this final rule. The following presents the comments received on the
NPRM and the FAA's response to each comment.

Request To Add Maximum Allowable Life

    The Air Line Pilots Association requested that we specify a maximum
allowable life for the parts affected by this AD, in addition to the
prescribed inspection interval, to ensure that the affected parts are
not operated beyond a life limit in which it is likely that fatigue
cracks will form.
    We disagree. This AD intends to specify a new inspection interval
to reduce the risk of a fan hub failure due to potential low-cycle
fatigue cracking. We determined that repetitive inspections, in
conjunction with existing life limits for the small population of
affected parts, maintains an acceptable level of safety for the fleet.
The life limits for the affected parts are given in the appropriate
Engine Manual, Chapter 5, Airworthiness Limitations Section. Operators
are responsible for complying with those life limits. We did not change
this AD.

Request To Clarify FPI Instructions

    All Nippon Airways requested clarification for performing the FPIs
required by this AD. The instructions for performing ECIs are specified
in PW Alert Service Bulletin (ASB) PW4G-112-A72-351, dated February 22,
2018, which is incorporated by reference by this AD; however,
instructions for performing FPIs are not specified.
    We disagree. FPI is an industry-standard inspection. Operators are
permitted to use an FPI process that is equivalent to the FPI process
conducted by the original equipment manufacturer. We are incorporating
by reference the instructions for performing ECIs because ECI is not an
industry standard practice. ECI requires procedures, tooling,
acceptance, and rejection criteria that are specific to the part being
inspected. We did not change this AD.

Request To Review Applicability

    PW stated that this AD should apply to all PW PW4074D, PW4077D,
PW4084D, PW4090, and PW4090-3 turbofan engines with LPC fan hub, P/N
51B821 or P/N 52B521, installed as of or after February 22, 2018.
    We disagree. The unsafe condition is present for any LPC fan hub,
P/N 51B521 or P/N 52B521, installed in PW PW4074D, PW4077D, PW4084D,
PW4090, and PW4090-3 turbofan engines regardless of the installation
date. This AD requires inspections of all applicable LPC fan hubs, P/N
51B521 or P/N 52B521, in service. We did not change this AD.

Clarification to Costs of Compliance

    We determined that we were not clear that only one LPC fan hub
might need replacing. We clarified this in our cost estimate.

Support for the AD

    The Boeing Company expressed support for the NPRM as written.

Conclusion

    We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
this final rule as proposed except for minor editorial changes. We have
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.

    We estimate the following costs to do any necessary replacements
that would be required based on the results of the proposed inspection.
We estimate that one engine will need this replacement and estimate the
parts cost using a prorated formula that takes the early removal of the
life-limited part into account.

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.
    We are 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.
    This AD is issued in accordance with authority delegated by the
Executive Director, Aircraft Certification Service, as authorized by
FAA Order 8000.51C. In accordance with that order, issuance of ADs is
normally a function of the Compliance and Airworthiness Division, but
during this transition period, the Executive Director has delegated the
authority to issue ADs applicable to engines, propellers, and
associated appliances to the Manager, Engine and Propeller Standards
Branch, Policy and Innovation Division.

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) Is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) 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.

(c) Applicability

    This AD applies to all Pratt & Whitney Division (PW) PW4074D,
PW4077D, PW4084D, PW4090, and PW4090-3 turbofan engines with low-
pressure compressor (LPC) fan hub, part number (P/N) 51B821 or P/N
52B521, installed.

(d) Subject

    Joint Aircraft System Component (JASC) Code 7230, Turbine Engine
Compressor Section.

(e) Unsafe Condition

    This AD was prompted by low-cycle fatigue analysis techniques,
updated by the engine manufacturer, which indicated certain LPC fan
hubs could crack before their published life limit. We are issuing
this AD to prevent failure of the LPC fan hub. The unsafe condition,
if not addressed, could result in uncontained hub release, damage to
the engine, and damage to the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified,
unless already done.

(g) Required Actions

    (1) After the effective date of this AD, perform a fluorescent
penetrant inspection (FPI) and an eddy current inspection (ECI) of
the LPC fan hub the next time the engine is separated at the M-
flange and the LPC fan hub has accumulated 2,000 or more flight
cycles since the last FPI and ECI.
    (2) Thereafter, perform an FPI and an ECI of the LPC fan hub
every time the engine is separated at the M-flange and the LPC fan
hub has accumulated 2,000 or more flight cycles since the last LPC
fan hub ECI and FPI.
    (3) Use the Accomplishment Instructions, Step No. 11, in PW
Alert Service Bulletin PW4G-112-A72-351, dated February 22, 2018, to
do the ECI.
    (4) If a crack is found during the inspections required by
paragraphs (g)(1) or (2) of this AD, remove the LPC fan hub from
service before further flight and replace with a part eligible for
installation.

(h) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, ECO Branch, FAA, has the authority to approve
AMOCs for this AD, if requested using the procedures found in 14 CFR
39.19. In accordance with 14 CFR 39.19, send your request to your
principal inspector or local flight standards district office, as
appropriate. If sending information directly to the manager of the
certification office, send it to the attention of the person
identified in paragraph (i) of this AD. You may email your request
to: [email protected].
    (2) Before using any approved AMOC, notify your appropriate
principal inspector, or lacking a principal inspector, the manager
of the local flight standards district office/certificate holding
district office.
