In response to requests from a Federal
employee who resides in King George
County, Virginia, OPM proposes to
designate that county as one in which
Federal employees may run for local
partisan political office, subject to the
limitations established by OPM, and
accept or receive political contributions
in connection with elections for local
public office. This proposal reflects
OPM’s determination that special or
unusual circumstances exist so that it is
in the domestic interest of Federal
employees residing in King George
County to participate in these political
activities. This determination is based
on written material provided by the
applicant, interviews with the
applicant, and documentary material
obtained through independent research.
Principal factors leading to OPM’s
determination are the proximity of King
George County to the District of
Columbia, the rapid growth of the
county within the past few years,
significant public issues associated with
this growth, and a significant Federal
presence within King George County.
A copy of this notice will be
published in two local newspapers
serving King George County.
If this proposed rule is adopted, OPM
will amend 5 CFR 733.107(c) by adding
King George County to the list of
designated Virginia municipalities and
political subdivisions in which Federal
Government employees may participate
in elections for local partisan political
office in accordance with the conditions
specified in 5 CFR 733.103–733.106.
The addition of King George County
will be listed after Herndon, Virginia,
and before Loudoun County, Virginia.
E.O. 12291, Federal Regulation
I have determined that this is not a
major rule as defined under section 1(b)
of E.O. 12291, Federal Regulation.

AGENCY:
We propose to adopt a new
airworthiness directive (AD) for the
products listed above. This proposed
AD results from mandatory continuing
airworthiness information (MCAI)
issued by an aviation authority of
another country to identify and correct
an unsafe condition on an aviation
product. The MCAI describes the unsafe
condition as:
SUMMARY:
U.S. Office of Personnel Management.
John Berry,
Director.
Fuel leaks from the engine have occurred
in-service due to damage to sections of the
fan case Low Pressure (LP) fuel tubes which
run between the Low Pressure and the High
Pressure (HP) fuel pumps. This damage has
been caused by frettage between the securing
clips and the tube outer surface, which has
caused localised thinning of the tube wall
thickness. The thinning of the tube wall
causes the tube to fracture and fuel loss to
occur.
Accordingly, the Office of Personnel
Management proposes to amend 5 CFR
part 733 as follows:
We are proposing this AD to prevent
engine fuel leaks, which could result in
risk to the airplane.

Discussion
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued EASA
Airworthiness Directive 2010–0188,
dated September 20, 2010 (referred to
after this as ‘‘the MCAI’’), to correct an
unsafe condition for the specified
products. The MCAI states:
Fuel leaks from the engine have occurred
in-service due to damage to sections of the
fan case Low Pressure (LP) fuel tubes which
run between the Low Pressure and the High
Pressure (HP) fuel pumps. This damage has
been caused by frettage between the securing
clips and the tube outer surface, which has
caused localised thinning of the tube wall
thickness. The thinning of the tube wall
causes the tube to fracture and fuel loss to
occur.
This AD requires inspection and, if
necessary, replacement of fan case LP fuel
tubes and clips.
jlentini on DSK4TPTVN1PROD with PROPOSALS
Relevant Service Information
Rolls-Royce plc has issued Alert
Service Bulletin RB.211–73–AD685,
Revision 5, dated August 18, 2010. The
actions described in this service
information are intended to correct the
unsafe condition identified in the
MCAI.
FAA’s Determination and Requirements
of this Proposed AD
This product has been approved by
the aviation authority of the United
Kingdom, and is approved for operation
in the United States. Pursuant to our
bilateral agreement with the United
Kingdom, they have notified us of the
unsafe condition described in the MCAI
and service information referenced
above. We are proposing this AD
because we evaluated all information
provided by EASA and determined the
unsafe condition exists and is likely to
exist or develop on other products of the
same type design.
Costs of Compliance
We estimate that this proposed AD
would affect about 110 products of U.S.
registry. We also estimate that it would
VerDate Mar<15>2010
16:46 Aug 19, 2011
Jkt 223001
take about 3 work-hours per product to
comply with this proposed AD. The
average labor rate is $85 per work-hour.
Required parts would cost about $225
per product. Based on these figures, we
estimate the cost of the proposed AD on
U.S. operators to be $52,800.
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 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. Is not a ‘‘significant rule’’ under the
DOT Regulatory Policies and Procedures
(44 FR 11034, February 26, 1979); and
(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.
We prepared a regulatory evaluation
of the estimated costs to comply with
this proposed AD and placed it in the
AD docket.

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the
products listed above. This proposed AD results from mandatory
continuing airworthiness information (MCAI) issued by an aviation
authority of another country to identify and correct an unsafe
condition on an aviation product. The MCAI describes the unsafe
condition as:
Fuel leaks from the engine have occurred in-service due to
damage to sections of the fan case Low Pressure (LP) fuel tubes
which run between the Low Pressure and the High Pressure (HP) fuel
pumps. This damage has been caused by frettage between the securing
clips and the tube outer surface, which has caused localised
thinning of the tube wall thickness. The thinning of the tube wall
causes the tube to fracture and fuel loss to occur.
We are proposing this AD to prevent engine fuel leaks, which could
result in risk to the airplane.
DATES: We must receive comments on this proposed AD by October 6, 2011.

Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued EASA
Airworthiness Directive 2010-0188, dated September 20, 2010 (referred
to after this as ``the MCAI''), to correct an unsafe condition for the
specified products. The MCAI states:
Fuel leaks from the engine have occurred in-service due to
damage to sections of the fan case Low Pressure (LP) fuel tubes
which run between the Low Pressure and the High Pressure (HP) fuel
pumps. This damage has been caused by frettage between the securing
clips and the tube outer surface, which has caused localised
thinning of the tube wall thickness. The thinning of the tube wall
causes the tube to fracture and fuel loss to occur.
This AD requires inspection and, if necessary, replacement of
fan case LP fuel tubes and clips.
Relevant Service Information
Rolls-Royce plc has issued Alert Service Bulletin RB.211-73-AD685,
Revision 5, dated August 18, 2010. The actions described in this
service information are intended to correct the unsafe condition
identified in the MCAI.

This product has been approved by the aviation authority of the
United Kingdom, and is approved for operation in the United States.
Pursuant to our bilateral agreement with the United Kingdom, they have
notified us of the unsafe condition described in the MCAI and service
information referenced above. We are proposing this AD because we
evaluated all information provided by EASA and determined the unsafe
condition exists and is likely to exist or develop on other products of
the same type design.
Costs of Compliance
We estimate that this proposed AD would affect about 110 products
of U.S. registry. We also estimate that it would take about 3 work-
hours per product to comply with this proposed AD. The average labor
rate is $85 per work-hour. Required parts would cost about $225 per
product. Based on these figures, we estimate the cost of the proposed
AD on U.S. operators to be $52,800.
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 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. Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979); and
(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.
We prepared a regulatory evaluation of the estimated costs to
comply with this proposed AD and placed it in the AD docket.

The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA 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 adding the following new AD:
Rolls-Royce plc: Docket No. FAA-2011-0836; Directorate Identifier
2010-NE-38-AD.
Comments Due Date
(a) We must receive comments by October 6, 2011.
Affected Airworthiness Directives (ADs)
(b) None.
Applicability
(c) This AD applies to Rolls-Royce plc (RR) Trent 875-17, 877-
17, 884-17, 884B-17, 892-17, 892B-17, and 895-17 turbofan engines.
These engines are installed on, but not limited to, Boeing 777
series airplanes.
Reason
(d) This AD results from:
Fuel leaks from the engine have occurred in-service due to
damage to sections of the fan case Low Pressure (LP) fuel tubes
which run between the Low Pressure and the High Pressure (HP) fuel
pumps. This damage has been caused by frettage between the securing
clips and the tube outer surface, which has caused localised
thinning of the tube wall thickness. The thinning of the tube wall
causes the tube to fracture and fuel loss to occur.
We are issuing this AD to prevent engine fuel leaks, which could
result in risk to the airplane.
Actions and Compliance
(e) Unless already done, do the following actions.
Initial Inspection
(f) Within 2,000 hours in service after the effective date of
this AD, or before accumulating 3,000 hours-since-new or 3,000
hours-since-last inspection, whichever is latest, do one of the
following:
On-wing Inspection
(1) Inspect the fan case LP fuel tubes (Part Numbers (P/N)
FK22617, FK19213 and FK23986) and the clips that hold the fuel tubes
in place. Use paragraphs 3.A.(2) and 3.A.(3) (On-wing) of RR Non-
Modification Service Bulletin (NMSB) RB.211-73-D685, Revision 5,
dated August 18, 2010, or
In-shop Inspection
(2) Inspect the fan case LP fuel tubes (P/N FK22617, FK19213 and
FK23986) and the clips that hold the fuel tubes in place. Use

Repetitive Inspection
(g) Following accomplishment of the initial inspection in
compliance with the requirements of paragraph (f)(1) or (f)(2) of
this AD, repeat the inspection at intervals not exceeding 3,000
hours, and, if necessary, replace the fan case LP fuel tubes (P/N
FK22617, FK19213 and FK23986) and the clips that hold the fuel tubes
in place. Use paragraphs 3.A.(2) and 3.A.(3) (On-wing) or 3.B.(2)
and 3.B.(3) (In-shop) of RR NMSB RB.211-73-D685, Revision 5, dated
