Basis and Purpose

    On February 6 and 7, 2012, the Marine Corps Base at Camp Lejeune,
North Carolina will be conducting military training operations on the
navigable waters of the Atlantic Intracoastal Waterway between position
34[deg]32'51'' N/077[deg]19'36'' W and 34[deg]34'15'' N/077[deg]16'16''
W (NAD 1983). Due to the need to protect mariners from the hazards
associated with the military training operations, vessel traffic will
be temporary restricted from Mile Hammock Bay and the Onslow Swing
Bridge.

Discussion of Proposed Rule

    The Coast Guard proposes establishing a safety zone on specified
waters of the Atlantic Intracoastal Waterway between position
34[deg]32'51'' N/077[deg]19'36'' W and 34[deg]34'15'' N/077[deg]16'16''
W (NAD 1983). This safety zone will be established in the vicinity of
Camp Lejeune, NC and enforced from 7 a.m. until 11 a.m. and from noon
until 4 p.m. on February 6, 2012, and from 7 a.m. until 11 a.m. and
from noon until 4 p.m. on February 7, 2012. In the interest of public
safety, general navigation within the safety zone will be restricted
during the specified date and times. Except for participants and
vessels authorized by the Coast Guard Captain of the Port or his
representative, no person or vessel may enter or remain in the
regulated area.

Regulatory Analyses

    We developed this proposed 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 proposed 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 proposed rule to be so
minimal that a full Regulatory Evaluation is unnecessary. Although this
proposed regulation restricts access to the safety zone, the effect of
this rule will not be significant because: (i) The safety zone will be
in effect for a limited duration; (ii) the zone is of limited size; and
(iii) the Coast Guard will make notifications via maritime advisories
so mariners can adjust their plans accordingly.

Small Entities

    Under the Regulatory Flexibility Act (5 U.S.C. 601-612), we have
considered whether this proposed 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 proposed
rule would not have a significant economic impact on a substantial
number of small entities because the zone will only be in place for a
limited duration, it is limited in size, and maritime advisories will
be issued allowing the mariners to adjust their plans accordingly.
    This proposed rule would affect the following entities, some of
which might be small entities: the owners and operators of vessels
intending to transit or anchor in that portion of the Atlantic
Intracoastal Waterway from 7 a.m. to 4 p.m. on February 6 and 7, 2012.
    If you think that your business, organization, or governmental
jurisdiction qualifies as a small entity and that this rule would have
a significant economic impact on it, please submit a comment (see
ADDRESSES) explaining why you think it qualifies and how and to what
degree this rule would economically affect it.

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 proposed rule so that they can better
evaluate its effects on them and participate in the rulemaking. 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 Chief Warrant Officer Joseph
Edge, Waterways Management Division Chief, Sector North Carolina, Coast
Guard; telephone<PHONE_NUMBER>, email<EMAIL_ADDRESS>The
Coast Guard will not retaliate against small entities that question or
complain about this proposed rule or any policy or action of the Coast
Guard.

Collection of Information

    This proposed rule would call 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 proposed 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 (adjusted for
inflation) or more in any one year. Though this proposed rule would not
result in such an expenditure, we do discuss the effects of this rule
elsewhere in this preamble.

Taking of Private Property

    This proposed rule would 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.

Civil Justice Reform

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

Environment

    We have analyzed this proposed 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 made a preliminary determination that this action is one of a
category of actions which do not individually or cumulatively have a
significant effect on

the human environment. A preliminary environmental analysis checklist
supporting this determination will be available in the docket where
indicated under ADDRESSES. We seek any comments or information that may
lead to the discovery of a significant environmental impact from this
proposed rule.

[Docket No. FAA-2005-19559; Directorate Identifier 2004-NE-03-AD]
RIN 2120-AA64

Airworthiness Directives; Rolls-Royce plc RB211 Trent 700 Series
Turbofan Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to supersede an existing airworthiness
directive (AD) for Rolls-Royce plc (RR) RB211 Trent 700 series turbofan
engines. That AD currently requires initial and repetitive borescope
inspections of the high pressure-and-intermediate pressure (HP-IP)
turbine internal and external oil vent tubes for coking and carbon
buildup, and cleaning or replacing the vent tubes if necessary. This
proposed AD would require the same actions, but would add additional
inspections of the vent flow restrictor. This proposed AD results from
further analysis that the cleaning of the vent tubes required by AD
2007-02-05 could lead to loosened carbon fragments, causing a blockage
downstream in the vent flow restrictor. We are proposing this AD to
prevent internal oil fires due to coking and carbon buildup that could
cause uncontained engine failure and damage to the airplane.

DATES: We must receive any comments on this proposed AD by December 28,
2009.

ADDRESSES: Use one of the following addresses to comment on this
proposed AD.

the Docket Operations office (telephone<PHONE_NUMBER>) is the same as
the Mail address provided in the ADDRESSES section. Comments will be
available in the AD docket shortly after receipt.

Discussion

    On January 12, 2007, the FAA issued AD 2007-02-05, Amendment 39-
14892 (72 FR 2603, January 22, 2007). The European Aviation Safety
Agency (EASA), which is the Technical Agent for the Member States of
the European Community, notified us that an unsafe condition may exist
on RB211 Trent 700 series turbofan engines. Since AD 2007-02-05 was
issued, EASA advises that further analysis has now identified that
previous intervention actions may have exacerbated the problem of
carbon formation in the vent pipe. These intervention actions are
believed to loosen carbon fragments which are subsequently released
during engine operation, leading to blockage downstream in the vent
flow restrictor. The resultant reduced vent pipe flow will then cause
accelerated carbon buildup inside the pipe and increased likelihood of
an internal oil fire.

Relevant Service Information

    We have reviewed and approved the technical contents of Rolls-Royce
plc Alert Service Bulletin (ASB) No. RB.211-72-AE302, Revision 7, dated
April 30, 2009. That ASB describes procedures for borescope inspections
of the HP-IP turbine internal and external oil vent tubes for coking
and carbon buildup, and cleaning or replacing the vent tubes if
necessary. That ASB also describes procedures for visual inspections of
the vent pipe restrictor immediately after pipe cleaning and a high-
power engine run. For internal oil vent tubes to pass inspection, they
must allow cleaning tool, number HU80298, to pass through them. EASA
classified this service bulletin as mandatory and issued AD 2007-0201
and AD 2007-0202 (corrected August 8, 2007), to ensure the
airworthiness of these RB211 Trent 700 series turbofan engines in
Europe.

Bilateral Agreement Information

    This engine model is manufactured in the United Kingdom and is type
certificated for operation in the United States under the provisions of
Section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and
the applicable bilateral airworthiness agreement. Under this bilateral
airworthiness agreement, EASA kept us informed of the situation
described above. We have examined the findings of the EASA, reviewed
all available information, and determined that AD action is necessary
for products of this type design that are certificated for operation in
the United States.

FAA's Determination and Requirements of the Proposed AD

    We have evaluated all pertinent information and identified an
unsafe condition that is likely to exist or develop on other products
of this same type design. We are proposing this AD, which would require
initial and repetitive borescope inspections of the HP-IP turbine
internal and external oil vent tubes for coking and carbon buildup, and
cleaning or replacing the vent tubes if necessary. This proposed AD
would also require visual inspections of the vent flow restrictor
immediately after pipe cleaning and a high-power engine run. We are
issuing this AD to prevent internal oil fires due to coking and carbon
buildup that could cause uncontained engine failure and damage to the
airplane. The proposed AD would require that you do these actions using
the service information described previously.

Table 1 Clarification

    We found it necessary to clarify the second sentence in the first
column of the Initial Inspection Table 1, which we carried forward from
AD 2007-02-05. We changed ``Has fewer than 10,000 hours TSN or fewer
than 2,500 CSN on the effective date of this AD'' to ``Has fewer than
10,000 hours TSN and fewer than 2,500 CSN on the effective date of this
AD.''

Costs of Compliance

    Based on the service information, we estimate that this proposed AD
would affect about 33 engines of U.S. registry. We also estimate that
it would take about one work-hour per engine to comply with this
proposed AD. The average labor rate is $80 per work-hour. Required
parts would cost about $2,000 per engine. Based on these figures, we
estimate the cost of the proposed AD on U.S. operators to be $68,640.

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.

Regulatory Findings

    We have 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 that the proposed AD:
    1. Is not a ``significant regulatory action'' under Executive Order
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979); 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.
    We prepared a regulatory evaluation of the estimated costs to
comply with this proposed AD. See the ADDRESSES section for a location
to examine the regulatory evaluation.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the
Administrator, the Federal Aviation Administration proposes to amend 14
CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

    1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.

Sec.  39.13  [Amended]

    2. The FAA amends Sec.  39.13 by removing Amendment 39-14892 (72 FR
2603, January 22, 2007) and by adding a new airworthiness directive, to
read as follows:

Rolls-Royce plc: Docket No. FAA-2005-19559; Directorate Identifier
2004-NE-03-AD.

Comments Due Date

    (a) The Federal Aviation Administration (FAA) must receive
comments on this airworthiness directive (AD) action by December 28,
2009.

Affected ADs

    (b) This AD supersedes AD 2007-02-05, Amendment 39-14892.

Applicability

    (c) This AD applies to Rolls-Royce plc (RR) RB211 Trent 768-60,
RB211 Trent 772-60, and RB211 Trent 772B-60 series turbofan engines.
These engines are installed on, but not limited to, Airbus A330-243,
-341, -342 and -343 series airplanes.

Unsafe Condition

    (d) This AD results from further analysis that the cleaning of
the vent tubes required by AD 2007-02-05 could lead to loosened
carbon fragments, causing a blockage downstream in the vent flow
restrictor. We are issuing this AD to prevent internal oil fires due
to coking and carbon buildup that could cause uncontained engine
failure and damage to the airplane.

Compliance
