applicability and legal effect, most of which
are keyed to and codified in the Code of
Federal Regulations, which is published under
50 titles pursuant to 44 U.S.C. 1510.
The Code of Federal Regulations is sold by

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

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.

specified Eurocopter model helicopters.
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. The
actions specified in this AD are
intended to restrict the VNE, to prevent
failure of the horizontal stabilizer, and
subsequent loss of control of the
helicopter.

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 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/

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 copilot 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
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.
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

SUMMARY: This amendment adopts a new airworthiness directive (AD) for
the
[[Page 68170]]
specified Eurocopter model helicopters. This action requires amending
the Limitations section of the Rotorcraft Flight Manual (RFM) to limit
the never-exceed 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 co-pilot.
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. The actions specified in this AD are intended to restrict
the VNE, to prevent failure of the horizontal stabilizer, and
subsequent loss of control of the helicopter.

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
may review the DOT's complete Privacy Act Statement in the Federal
Register published on April 11, 2000 (65 FR 19477-78).
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.
