The Code of Federal Regulations is sold by the Superintendent of Documents. Prices of new books are listed in the first FEDERAL REGISTER issue of each week. FEDERAL RETIREMENT THRIFT INVESTMENT BOARD Regulatory Flexibility Act 5 CFR Part 1601 Participants’ Choices of TSP Funds Federal Retirement Thrift Investment Board. ACTION: Correcting amendment. AGENCY: This document contains a correction to a final regulation that amended the Thrift Savings Plan regulations, which was published in the Federal Register of June 1, 2005 (70 FR 32208). DATES: Effective on November 5, 2010. FOR FURTHER INFORMATION CONTACT: Laurissa Stokes at 202–942–1645. SUPPLEMENTARY INFORMATION: The Agency administers the Thrift Savings Plan (TSP), which was established by the Federal Employees’ Retirement System Act of 1986 (FERSA), Public Law 99–335, 100 Stat. 514. The TSP provisions of FERSA are codified, as amended, largely at 5 U.S.C. 8351 and 8401–79. The TSP is a tax-deferred retirement savings plan for Federal civilian employees and members of the uniformed services. The TSP is similar to cash or deferred arrangements established for private-sector employees under section 401(k) of the Internal Revenue Code (26 U.S.C. 401(k)). The final regulation that is the subject of this correction was published in the Federal Register on June 1, 2005 (70 FR 32208). As published, the final regulation contains an error or omission that may be misleading and needs to be clarified. Section 1601.32 of 5 CFR states that contribution allocations or interfund transfer requests received at or before 12 noon eastern time of any business day will ordinarily be posted that business day. However, TSP participant publications all state that contribution allocations or interfund transfer requests mstockstill on DSKH9S0YB1PROD with RULES SUMMARY: VerDate Mar<15>2010 16:35 Nov 04, 2010 Jkt 223001 received before 12 noon eastern time of any business day will ordinarily be posted that business day. Although the likelihood of the Agency receiving a request precisely at noon is low, and the modifier ‘‘ordinarily’’ would afford the Agency the opportunity to process the transaction the next business day, this final rule corrects the erroneous language to make the regulation consistent with TSP participant publications. List of Subjects in 5 CFR Part 1601 Government employees, Pensions, Retirement. Gregory T. Long, Executive Director, Federal Retirement Thrift Investment Board. Accordingly, 5 CFR part 1601 is corrected by making the following correcting amendment: ■ PART 1601—PARTICIPANTS’ CHOICES OF TSP FUNDS 1. The authority citation for part 1601 continues to read as follows: ■ I certify that this regulation will not have a significant economic impact on a substantial number of small entities. This regulation will affect Federal employees and members of the uniformed services who participate in the Thrift Savings Plan, which is a Federal defined contribution retirement savings plan created under the Federal Employees’ Retirement System Act of 1986 (FERSA), Public Law 99–335, 100 Stat. 514, and which is administered by the Agency. Paperwork Reduction Act I certify that these regulations do not require additional reporting under the criteria of the Paperwork Reduction Act.

(a) * * * (1) A transaction request entered into the TSP record keeping system by a participant who uses the TSP Web site or the ThriftLine, or by a TSP Service Office participant service representative at the participant’s request, before 12 noon eastern time of any business day, will ordinarily be posted that business day. A transaction request entered into the system at or after 12 noon eastern time of any business day will ordinarily be posted on the next business day. * * * * * [FR Doc. 2010–28000 Filed 11–4–10; 8:45 am] Pursuant to the Unfunded Mandates Reform Act of 1995, 2 U.S.C. 602, 632, 653, 1501–1571, the effects of this regulation on state, local, and tribal governments and the private sector have been assessed. This regulation will not compel the expenditure in any one year of $100 million or more by state, local, and tribal governments, in the aggregate, or by the private sector. Therefore, a statement under section 1532 is not required. Submission to Congress and the Government Accountability Office Pursuant to 5 U.S.C. 810(a)(1)(A), the Agency submitted a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States before publication of this rule in the Federal Register.

This action requires amending the Limitations section of the Rotorcraft Flight Manual (RFM) to limit the neverexceed velocity (VNE) to 150 Knots Indicated Air Speed (KIAS) and to add a 1,500 ft/minute rate of descent (R/D) limitation beyond 140 KIAS. This action also requires installing one or more placards on the cockpit instrument panel in full view of the pilot and copilot. This amendment is prompted by failures of the horizontal stabilizers on recently delivered Model AS 365 N3 helicopters. Tests indicate that the failures were due to a vibration phenomenon that may arise during the descent flight phases at high speed regardless of the stabilizer installed.

SUPPLEMENTARY INFORMATION: D must not exceed 1,500 ft/min beyond 140 KIAS. Eurocopter states in the EASB that it is working on an enhanced definition that will be proposed as soon as possible. EASA classified this EASB as mandatory and issued Emergency AD No. 2008–0204–E, dated December 4, 2008, to ensure the continued airworthiness of these helicopters. Discussion FAA’s Evaluation and Unsafe Condition Determination These helicopters have been approved by the aviation authority of France and are approved for operation in the United States. Pursuant to our bilateral agreement with France, EASA, their technical representative, has notified us of the unsafe condition described in the MCAI AD. We are issuing 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 helicopters of these same type designs. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Emergency AD No. 2008–0204–E, dated December 4, 2008, to correct an unsafe condition for the specified Eurocopter model helicopters. EASA advises that Eurocopter has received reports of failed horizontal stabilizers on recently delivered AS 365 N3 helicopters. The failures occurred during acceptance test and training flights as part of the demonstration of the VNE and resulted in in-flight separation and loss of the failed sections. In each case, the helicopters succeeded in returning to base with no further problems. Tests conducted on the helicopter and in the laboratory have revealed the reported incidents were due to a vibration phenomenon that may arise in the descent flight phases at high speed ‘‘regardless of the stabilizer definition.’’ Although EASA AD 2008–0110–E, dated June 6, 2008, which is superseded by EASA AD 2008–0204–E, dated December 4, 2008, applied to the Model SA–336G1, EASA states that the stabilizer assembly procedure on SA– 366G1 helicopters modifies the dynamic behavior of the stabilizer. Since an unsafe condition does not exist on that helicopter, the SA–366G1 has been deleted from the EASA AD applicability. Related Service Information Eurocopter has issued an Emergency Alert Service Bulletin (EASB) with 3 numbers (01.00.60, 01.00.16, and 01.28), Revision 1, dated December 2, 2008. EASB No. 01.00.60 applies to U.S. typecertificated Model SA–365N, SA– 365N1, AS–365N2, and AS 365 N3 helicopters and also to military Model AS365F, Fs, Fi, and K helicopters that are not type certificated in the United States. EASB No. 01.00.16 applies to military Model AS565AA, MA, MB, SA, SB, and UB helicopters that are not type certificated in the United States. EASB 01.28 applies to the Model SA–366G1 helicopter.

The change to the Operating limitation section of the RFM may be made in pen and ink or a copy of this AD may be filed in the Limitations section of the RFM. The short compliance time involved is required because the previously described critical unsafe condition can adversely affect the controllability and structural integrity of the helicopter. Amending the Limitations section of the RFM to limit the VNE to 150 KIAS and adding a 1,500 ft/minute R/D limitation beyond 140 KIAS are required before further flight and installing one or more placards on the cockpit instrument panel is required.

Since a situation exists that requires the immediate adoption of this E:\FR\FM\05NOR1.SGM 05NOR1 Federal Register / Vol. 75, No. 214 / Friday, November 5, 2010 / Rules and Regulations regulation, it is found that notice and opportunity for prior public comment hereon are impracticable, and that good cause exists for making this amendment effective in less than 30 days. Costs of Compliance We estimate that this AD will affect about 39 helicopters of U.S. registry. We also estimate that it will take about l⁄2 work-hour per helicopter to make copies to include in the RFM and to make and install the placards. The average labor rate is $85 per work-hour. The parts costs are minimal. Based on these figures, we estimate the cost of this AD on U.S. operators is $1,658 for the fleet.

SUPPLEMENTARY INFORMATION:

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Emergency AD No. 2008-0204-E, dated December 4, 2008, to correct an 
unsafe condition for the specified Eurocopter model helicopters. EASA 
advises that Eurocopter has received reports of failed horizontal 
stabilizers on recently delivered AS 365 N3 helicopters. The failures 
occurred during acceptance test and training flights as part of the 
demonstration of the VNE and resulted in in-flight separation and loss 
of the failed sections. In each case, the helicopters succeeded in 
returning to base with no further problems. Tests conducted on the 
helicopter and in the laboratory have revealed the reported incidents 
were due to a vibration phenomenon that may arise in the descent flight 
phases at high speed ``regardless of the stabilizer definition.'' 
Although EASA AD 2008-0110-E, dated June 6, 2008, which is superseded 
by EASA AD 2008-0204-E, dated December 4, 2008, applied to the Model 
SA-336G1, EASA states that the stabilizer assembly procedure on SA-
366G1 helicopters modifies the dynamic behavior of the stabilizer. 
Since an unsafe condition does not exist on that helicopter, the SA-
366G1 has been deleted from the EASA AD applicability.

Related Service Information

    Eurocopter has issued an Emergency Alert Service Bulletin (EASB) 
with 3 numbers (01.00.60, 01.00.16, and 01.28), Revision 1, dated 
December 2, 2008. EASB No. 01.00.60 applies to U.S. type-certificated 
Model SA-365N, SA-365N1, AS-365N2, and AS 365 N3 helicopters and also 
to military Model AS365F, Fs, Fi, and K helicopters that are not type 
certificated in the United States. EASB No. 01.00.16 applies to 
military Model AS565AA, MA, MB, SA, SB, and UB helicopters that are not 
type certificated in the United States. EASB 01.28 applies to the Model 
SA-366G1 helicopter. The EASB specifies bonding one or more locally-
produced labels to the instrument panel stating that the VNE is limited 
to 150 KIAS and the R/D must not exceed 1,500 ft/min beyond 140 KIAS. 
Eurocopter states in the EASB that it is working on an enhanced 
definition that will be proposed as soon as possible. EASA classified 
this EASB as mandatory and issued Emergency AD No. 2008-0204-E, dated 
December 4, 2008, to ensure the continued airworthiness of these 
helicopters.

FAA's Evaluation and Unsafe Condition Determination

    These helicopters have been approved by the aviation authority of 
France and are approved for operation in the United States. Pursuant to 
our bilateral agreement with France, EASA, their technical 
representative, has notified us of the unsafe condition described in 
the MCAI AD. We are issuing 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 helicopters of these same 
type designs.

Differences Between This AD and the EASA AD

    This AD uses a compliance time of before further flight rather than 
before next flight after June 7, 2008, as stated in the EASA AD.

FAA's Determination and Requirements of This AD

    This unsafe condition is likely to exist or develop on other 
helicopters of these same type designs. Therefore, this AD is being 
issued to restrict the VNE to prevent failure of the horizontal 
stabilizer and subsequent loss of control of the helicopter. This AD 
requires amending the Limitations section of the RFM to limit the VNE 
to 150 KIAS and to add a 1,500 ft/minute R/D limitation for airspeeds 
beyond 140 KIAS. This action also requires installing one or more 
placards on the cockpit instrument panel in full view of the pilot and 
co-pilot stating the limitations. The change to the Operating 
limitation section of the RFM may be made in pen and ink or a copy of 
this AD may be filed in the Limitations section of the RFM.
    The short compliance time involved is required because the 
previously described critical unsafe condition can adversely affect the 
controllability and structural integrity of the helicopter. Amending 
the Limitations section of the RFM to limit the VNE to 150 KIAS and 
adding a 1,500 ft/minute R/D limitation beyond 140 KIAS are required 
before further flight and installing one or more placards on the 
cockpit instrument panel is required. Therefore, this AD must be issued 
immediately.
    Since a situation exists that requires the immediate adoption of 
this

[[Page 68171]]

regulation, it is found that notice and opportunity for prior public 
comment hereon are impracticable, and that good cause exists for making 
this amendment effective in less than 30 days.

Costs of Compliance

    We estimate that this AD will affect about 39 helicopters of U.S. 
registry. We also estimate that it will take about \l/2\ work-hour per 
helicopter to make copies to include in the RFM and to make and install 
the placards. The average labor rate is $85 per work-hour. The parts 
costs are minimal. Based on these figures, we estimate the cost of this 
AD on U.S. operators is $1,658 for the fleet.

Comments Invited

    This AD is a final rule that involves requirements that affect 
flight safety and was not preceded by notice and an opportunity for 
public comment; however, we invite you to submit any written data, 
views, or arguments regarding this AD. Send your comments to an address 
listed under ADDRESSES. Include ``Docket No. FAA-2010-1082; Directorate 
Identifier 2009-041-SW-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of the AD. We will consider all 
comments received by the closing date and may amend the AD in light of 
those comments.
    We will post all comments we receive, without change, to https://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact 
with FAA personnel concerning this AD. Using the search function of the 
docket web site, you can find and read the comments to any of our 
dockets, including the name of the individual who sent the comment. You

Regulatory Findings

    We have determined that 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 the 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 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 an economic evaluation of the estimated costs to comply 
with this AD. See the AD docket to examine the economic evaluation.

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 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.

Adoption of the Amendment

0
Accordingly, pursuant to the authority delegated to me by the 
Administrator, the Federal Aviation Administration amends part 39 of 
the Federal Aviation Regulations (14 CFR part 39) as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
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]

0
2. Section 39.13 is amended by adding a new airworthiness directive to 
read as follows:

2010-23-02 Eurocopter France: Amendment 39-16491; Docket No. FAA-
2010-1082; Directorate Identifier 2009-SW-041-AD.

    Applicability: Model SA-365N, SA-365N1, AS-365N2, and AS 365 N3-
helicopters, with a horizontal stabilizer, part number 365A13-3030-
1901, -1902, -1903, -1904, -1905, -1906, -1908, -1909; 365A13-3036-
00, -0001, -0002, -0003; or 365A13-3038-00, installed, certificated 
in any category.
    Compliance: Before further flight, unless accomplished 
previously.
    To restrict the never-exceed velocity (VNE) to prevent failure 
of the horizontal stabilizer, and subsequent loss of control of the 
helicopter, do the following:
    (a) Revise the airspeed operating limitation in the Limitations 
section of the Rotorcraft Flight Manual (RFM) by making pen and ink 
changes or by inserting a copy of this AD into the RFM stating: 
``The never-exceed speed (VNE) is limited to 150 knots indicated 
airspeed (KIAS),'' and ``The rate-of-descent (R/D) must not exceed 
1,500 ft/min when the airspeed is beyond 140 KIAS.''
    (b) Install one or more self-adhesive placards, with 6 
millimeter red letters on white background, on the cockpit 
instrument panel in full view of the pilot and co-pilot to read as 
follows:
    ``VNE LIMITED TO 150 KIAS''
    ``R/D MUST NOT EXCEED 1,500 ft/min when airspeed is beyond 140 
KIAS''
    (c) To request a different method of compliance or a different 
compliance time for this AD, follow the procedures in 14 CFR 39.19.
