Discussion EASA, which is the Technical Agent for the Member States of the European Union, issued EASA AD No. 2013–0176, dated August 7, 2013, to correct an unsafe condition for Eurocopter Deutschland GmbH Model EC 135 P1 (CDS), EC 135 P1 (CPDS), EC 135 P2+, EC 135 P2 (CPDS), EC 135 T1 (CDS), EC PO 00000 Frm 00015 Fmt 4702 Sfmt 4702 48707 135 T1 (CPDS), EC 135 T2+, EC 135 T2 (CPDS), EC 635 P2+, EC 635 T1 (CPDS), EC 635 T2+, and MBB–BK 117 C–2 helicopters. EASA advises that during installation work on a helicopter, it was discovered that it was not possible to install attachment hardware on a threaded blind borehole between the SEMA and the control rod without play. According to EASA, the loose attachment hardware was caused by an ‘‘unfavourable adding of the tolerances’’ of the individual attachment hardware elements. EASA states that as a result, the screw pushed against the bottom of the threaded blind borehole on the SEMA, and no clamping force could be achieved on the screw head. EASA advises that this condition, if not detected and corrected, could lead to loss of the concerned control axis, possibly resulting in loss of helicopter control. For these reasons, EASA AD No. 2013–0176 requires a one-time inspection of the affected SEMA attachment hardware to detect improper connection and play and, depending on the findings, replacement of the affected hardware. Since the issuance of EASA AD No. 2013–0176, Eurocopter Deutschland GmbH has changed its name to Airbus Helicopters Deutschland GmbH. FAA’s Determination These helicopters have been approved by the aviation authority of Germany and are approved for operation in the United States. Pursuant to our bilateral agreement with Germany, EASA, its technical representative, has notified us of the unsafe condition described in its AD. We are proposing this AD because we evaluated all known relevant information and determined that an unsafe condition is likely to exist or develop on other products of the same type design. Related Service Information Eurocopter reported in Alert Service Bulletins (ASBs) EC135–22A–015, Revision 1, dated January 28, 2013, and MBB BK117 C–2–22A–009, Revision 1, dated August 3, 2009, that it was discovered during the installation work on a helicopter that it was not possible to establish attachment hardware on a threaded blind borehole between the SEMA and the control rod without play. The ASBs state that ‘‘unfavourable adding of the tolerances’’ of the individual attachment hardware elements caused the screw to push against the bottom of the threaded blind borehole on the SEMA, preventing any clamping force on the screw head. The ASBs call for inspecting the SEMA attachment hardware connected to their E:\FR\FM\18AUP1.SGM 18AUP1 48708 Federal Register / Vol. 79, No. 159 / Monday, August 18, 2014 / Proposed Rules respective control rods for play and making the proper adjustments to eliminate any play. Proposed AD Requirements This proposed AD would require, within 50 hours time-in-service, inspecting whether the washers can be moved in the attachment hardware that connects the SEMA and the control rod of the longitudinal, lateral, and yaw actuators. For Model MBB BK117 C–2 helicopters, this inspection is only for the hardware connecting the YawSEMA and the Yaw-SEMA control rod. If none of the washers can be moved, then no further action is needed. If a washer can be moved, then this proposed AD would require replacing the four screws, installing two additional washers, and torquetightening the screws to 5–6 Nm. Differences Between This Proposed AD and the EASA AD The EASA AD applies to Eurocopter Model EC635P2+, EC635T1 and EC635T2+ helicopters. The proposed AD does not apply to these model helicopters because they have no FAA type certificate. tkelley on DSK3SPTVN1PROD with PROPOSALS Costs of Compliance We estimate that this proposed AD would affect 385 helicopters of U.S. Registry and that labor costs average $85 per work-hour. Based on these estimates, we expect the following costs: • Inspecting for movement of the washers would require 1.5 work hours for a labor cost of $128 per helicopter and $49,280 for the U.S. fleet. • Replacing the screws and related work would require an additional 0.5 work-hours for a labor cost of $43. Screws would cost $4 each while washers would cost $10 each. We estimate the cost would be $79 per repair. 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 proposed VerDate Mar<15>2010 16:52 Aug 15, 2014 Jkt 232001 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, 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); 3. Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction; 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 an economic evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.

The Securities and Exchange Commission is proposing an amendment to temporary rule 206(3)–3T [17 CFR 275.206(3)–3T] under the Investment Advisers Act of 1940 [15 U.S.C. 80b] that would extend the date on which the rule will sunset from December 31, 2014 to December 31, 2016. SUPPLEMENTARY INFORMATION: PO 00000 Frm 00017 Fmt 4702 Sfmt 4702 48709 I. Background On September 24, 2007, we adopted, on an interim final basis, rule 206(3)– 3T, a temporary rule under the Investment Advisers Act of 1940 (the ‘‘Advisers Act’’) that provides an alternative means for investment advisers that are registered with us as broker-dealers to meet the requirements of section 206(3) of the Advisers Act when they act in a principal capacity in transactions with certain of their advisory clients.1 The purpose of the rule was to permit broker-dealers to sell to their advisory clients, in the wake of Financial Planning Association v. SEC (the ‘‘FPA Decision’’),2 certain securities held in the proprietary accounts of their firms that might not be available on an agency basis—or might be available on an agency basis only on less attractive terms 3—while protecting clients from conflicts of interest as a result of such transactions.4 As initially adopted on an interim final basis, rule 206(3)–3T was set to sunset on December 31, 2009. In December 2009, however, we adopted rule 206(3)–3T as a final rule in the same form in which it was adopted on an interim final basis in 2007, except that we extended the rule’s sunset date by one year to December 31, 2010.5 We 1 Rule 206(3)–3T [17 CFR 275.206(3)–3T]. All references to rule 206(3)–3T and the various sections thereof in this release are to 17 CFR 275.206(3)–3T and its corresponding sections. See also Temporary Rule Regarding Principal Trades with Certain Advisory Clients, Investment Advisers Act Release No. 2653 (Sep. 24, 2007) [72 FR 55022 (Sep. 28, 2007)] (‘‘2007 Principal Trade Rule Release’’). 2 482 F.3d 481 (D.C. Cir. 2007). In the FPA Decision, handed down on March 30, 2007, the Court of Appeals for the DC Circuit vacated (subject to a subsequent stay until October 1, 2007) rule 202(a)(11)–1 under the Advisers Act. Rule 202(a)(11)–1 provided, among other things, that feebased brokerage accounts were not advisory accounts and were thus not subject to the Advisers Act. For further discussion of fee-based brokerage accounts, see 2007 Principal Trade Rule Release, Section I. 3 See 2007 Principal Trade Rule Release at nn.19– 20 and Section VI.C. 4 As a consequence of the FPA Decision, brokerdealers offering fee-based brokerage accounts with an advisory component became subject to the Advisers Act with respect to those accounts, and the client relationship became fully subject to the Advisers Act. These broker-dealers—to the extent they wanted to continue to offer fee-based accounts and met the requirements for registration—had to: Register as investment advisers, if they had not done so already; act as fiduciaries with respect to those clients; disclose all material conflicts of interest; and otherwise fully comply with the Advisers Act, including the restrictions on principal trading contained in section 206(3) of the Act.

Discussion

    EASA, which is the Technical Agent for the Member States of the 
European Union, issued EASA AD No. 2013-0176, dated August 7, 2013, to 
correct an unsafe condition for Eurocopter Deutschland GmbH Model EC 
135 P1 (CDS), EC 135 P1 (CPDS), EC 135 P2+, EC 135 P2 (CPDS), EC 135 T1 
(CDS), EC 135 T1 (CPDS), EC 135 T2+, EC 135 T2 (CPDS), EC 635 P2+, EC 
635 T1 (CPDS), EC 635 T2+, and MBB-BK 117 C-2 helicopters. EASA advises 
that during installation work on a helicopter, it was discovered that 
it was not possible to install attachment hardware on a threaded blind 
borehole between the SEMA and the control rod without play. According 
to EASA, the loose attachment hardware was caused by an ``unfavourable 
adding of the tolerances'' of the individual attachment hardware 
elements. EASA states that as a result, the screw pushed against the 
bottom of the threaded blind borehole on the SEMA, and no clamping 
force could be achieved on the screw head. EASA advises that this 
condition, if not detected and corrected, could lead to loss of the 
concerned control axis, possibly resulting in loss of helicopter 
control. For these reasons, EASA AD No. 2013-0176 requires a one-time 
inspection of the affected SEMA attachment hardware to detect improper 
connection and play and, depending on the findings, replacement of the 
affected hardware.
    Since the issuance of EASA AD No. 2013-0176, Eurocopter Deutschland 
GmbH has changed its name to Airbus Helicopters Deutschland GmbH.

FAA's Determination

    These helicopters have been approved by the aviation authority of 
Germany and are approved for operation in the United States. Pursuant 
to our bilateral agreement with Germany, EASA, its technical 
representative, has notified us of the unsafe condition described in 
its AD. We are proposing this AD because we evaluated all known 
relevant information and determined that an unsafe condition is likely 
to exist or develop on other products of the same type design.

Related Service Information

    Eurocopter reported in Alert Service Bulletins (ASBs) EC135-22A-
015, Revision 1, dated January 28, 2013, and MBB BK117 C-2-22A-009, 
Revision 1, dated August 3, 2009, that it was discovered during the 
installation work on a helicopter that it was not possible to establish 
attachment hardware on a threaded blind borehole between the SEMA and 
the control rod without play. The ASBs state that ``unfavourable adding 
of the tolerances'' of the individual attachment hardware elements 
caused the screw to push against the bottom of the threaded blind 
borehole on the SEMA, preventing any clamping force on the screw head. 
The ASBs call for inspecting the SEMA attachment hardware connected to 
their

eliminate any play.

Proposed AD Requirements

    This proposed AD would require, within 50 hours time-in-service, 
inspecting whether the washers can be moved in the attachment hardware 
that connects the SEMA and the control rod of the longitudinal, 
lateral, and yaw actuators. For Model MBB BK117 C-2 helicopters, this 
inspection is only for the hardware connecting the Yaw-SEMA and the 
Yaw-SEMA control rod. If none of the washers can be moved, then no 
further action is needed. If a washer can be moved, then this proposed 
AD would require replacing the four screws, installing two additional 
washers, and torque-tightening the screws to 5-6 Nm.

Differences Between This Proposed AD and the EASA AD

    The EASA AD applies to Eurocopter Model EC635P2+, EC635T1 and 
EC635T2+ helicopters. The proposed AD does not apply to these model 
helicopters because they have no FAA type certificate.

Costs of Compliance

    We estimate that this proposed AD would affect 385 helicopters of 
U.S. Registry and that labor costs average $85 per work-hour. Based on 
these estimates, we expect the following costs:
     Inspecting for movement of the washers would require 1.5 
work hours for a labor cost of $128 per helicopter and $49,280 for the 
U.S. fleet.
     Replacing the screws and related work would require an 
additional 0.5 work-hours for a labor cost of $43. Screws would cost $4 
each while washers would cost $10 each. We estimate the cost would be 
$79 per repair.

 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 proposed 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, 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);
    3. Will not affect intrastate aviation in Alaska to the extent that 
it justifies making a regulatory distinction; 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 an economic evaluation of the estimated costs to comply 
with this proposed AD and placed it in the AD docket.
