Requests for Hatch Act advisory opinions may be made by e-mail to: hatchact@osc.gov. 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. jlentini on DSK4TPTVN1PROD with PROPOSALS Regulatory Flexibility Act I certify that this regulation will not have a significant economic impact on a substantial number of small entities because the changes will affect only employees of the Federal Government.

ACTION: Notice of proposed rulemaking (NPRM). 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.

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

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.

ADDRESSES: You may send comments by any of the following methods:

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.

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 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.

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

Revision 5, dated August 18, 2010.

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 
August 18, 2010.

FAA AD Differences

    (h) None.

Alternative Methods of Compliance (AMOCs)
