National Environmental Policy Act Pursuant to the National Environmental Policy Act and the requirements of 42 U.S.C. 6295(o)(2)(B)(i)(VI), DOE prepared an environmental assessment (EA) of the impacts of the standards for residential furnaces, central air conditioners, and heat pumps in the direct final rule, which was included as chapter 15 of the direct final rule TSD. DOE found that the environmental effects associated with the standards for furnaces and central air conditioners and heat pumps were not significant. Therefore, after consideration of the comments received on the direct final rule, DOE issued a Finding of No Significant Impact (FONSI) pursuant to NEPA, the regulations of the Council on Environmental Quality (40 CFR parts 1500–1508), and DOE’s regulations for compliance with NEPA (10 CFR part 1021). The FONSI is available in the docket for this rulemaking at http:// www.regulations.gov. V. Conclusion In summary, based on the discussion above, DOE has determined that the comments received in response to the direct final rule for amended energy conservation standards for residential furnaces, central air conditioners, and heat pumps do not provide a reasonable basis for withdrawal of the direct final rule. As a result, the amended energy conservation standards set forth in the direct final rule become effective on October 25, 2011. Compliance with these standards is required on May 1, 2013 for non-weatherized gas and oilfired furnaces and mobile home gas furnaces and on January 1, 2015 for weatherized gas furnaces and central air conditioners and heat pumps. mstockstill on DSK4VPTVN1PROD with RULES Issued in Washington, DC, on October 24, 2011.

Your request was submitted under Section 325(o)(2)(B)(i)(V) of the Energy Policy and Conservation Act, as amended (ECPA), 42 U.S.C. 6295(o)(2)(B)(i)(5) and 42 U.S.C. 6316(a), which requires the Attorney General to make a determination of the impact of any lessening of competition that is likely to result from the imposition of proposed energy conservation standards. The Attorney General’s responsibility for responding to requests from other departments about the effect of a program on competition has been delegated to the Assistant Attorney General for the Antitrust Division in 28 CFR 0.40(g). In conducting its analysis the Antitrust Division examines whether a proposed standard may lessen competition, for example, by substantially limiting consumer choice, by placing certain manufacturers at an unjustified competitive disadvantage, or by inducing avoidable inefficiencies in production or distribution of particular products. A lessening of competition could result in higher prices to consumers, and perhaps thwart the intent of the revised standards by inducing substitution to less efficient products. We have reviewed the proposed standards contained in the Direct Final Rule (76 Fed. Reg. 37408, June 27, 2011). We have also reviewed supplementary information submitted to the Attorney General by the Department of Energy. Based on this review, our conclusion is that the proposed energy conservation standards for residential furnaces, residential central air conditioners and heat pumps are unlikely to have a significant adverse impact on competition. In reaching our conclusion, we note that these proposed energy standards were adopted from a Consensus Agreement signed by a broad cross-section of industry participants. Sincerely, Sharis A.

AGENCY: PO 00000 Frm 00015 Fmt 4700 Sfmt 4700 67051 We are publishing in the Federal Register an amendment which was sent previously to all known U.S. owners and operators that supersedes an existing airworthiness directive (AD) for the specified Bell Helicopter Textron, Inc. (BHT) Model helicopters with certain tail rotor blades (blades). The superseded AD requires, before further flight, replacing certain blades with airworthy blades. This AD retains the requirements of the superseded AD but adds new blade part numbers (P/Ns) and serial numbers (S/Ns) to the applicability. This AD was prompted by another incident in which the blade tip weight separated from a blade during flight, causing vibration. This incident led to the determination that additional blades could be affected, and should be added to the applicability. We are issuing this AD to prevent loss of the blade tip weight, loss of a blade, and subsequent loss of control of the helicopter. SUMMARY: This AD is effective November 15, 2011 to all persons except those persons to whom it was made immediately effective by Emergency AD 2010–26–52, issued on December 10, 2010, which contained the requirements of this amendment.

ADDRESSES SUPPLEMENTARY INFORMATION: Discussion We are publishing in the Federal Register an amendment adopting Emergency AD 2010–26–52, issued December 10, 2010 (EAD 2010–26–52), which was sent to all known owners and operators of BHT Model 204B, 205A, 205A–1, 205B, 210, 212, 412, 412CF, and 412EP helicopters with certain blades installed. EAD 2010–26– 52 supersedes AD 2007–19–53, Amendment 39–15265 (72 FR 65224, November 20, 2007) issued October 31, 2007 (AD 2007–19–53). AD 2007–19–53 required, before further flight, replacing certain blades with airworthy blades. That action was prompted by three reports of blade tip weights being slung from the blades during flights, causing significant vibration. We issued AD 2007–19–53 on a limited number of blades to address this unsafe condition, which could result in the loss of the blade tip weight, loss of a blade, and subsequent loss of control of the helicopter. • No. 212–07–125, Revision B, for Model 212 helicopters; • No. 412CF–07–30, Revision B, for Model 412CF helicopters; • No. 412–07–123, Revision B, for Model 412 and 412EP helicopters. Actions Since AD was Issued Since we issued AD 2007–19–53, another incident occurred in which the blade tip weight separated from a blade during flight, causing vibration. This incident led to the determination that additional blades could be affected and these blade numbers should be added to the applicability section of the AD. We issued superseding EAD 2010–26–52 which retains the same requirements of AD 2007–19–53, but adds new blade P/ Ns and S/Ns to the applicability. We are issuing this AD because we evaluated all relevant information and determined the unsafe condition described previously is likely to exist or develop on other helicopters of the same type designs. We have also determined that Emergency AD 2010–26–52 contained an incorrect Alert Service Bulletin (ASB) number for the Model 412CF helicopters in the preamble discussion. Therefore, we are making a change to this AD to correct the ASB number. We have also made other minor editorial changes to this AD, including reorganizing the Applicability table. We have determined that these changes do not increase the economic burden on any AD operator nor do they increase the scope of the AD. Relevant Service Information We have reviewed the following revised BHT Alert Service Bulletins (ASBs), all dated November 22, 2010 except for ASB No. 204–07–61. Each ASB contains a Rotor Blades Inc. (RBI) letter that adds blade P/Ns and S/Ns to the RBI list. • No. 204–07–61, Revision A, dated September 19, 2007, for Model 204 helicopters; • No. 205–07–95, Revision B, for Model 205 helicopters; • No. 205B–07–46, Revision B, for Model 205B helicopters; FAA’s Determination AD Requirements This AD requires, before further flight, unless already accomplished, replacing any affected blade with an airworthy blade. An airworthy blade is one that has a P/N and S/N not included in the Applicability section of this AD. Affected blades are those having a P/N and S/N as follows: Part No. Serial No. 204–011–702–015 .............. 204–011–702–121 .............. 212–010–750–105 .............. 212–010–750–105FM ........ 212–010–750–113 .............. 212–010–750–113FM ........

The short compliance time of before further flight justifies waiving notice and comment prior to adoption of this rule because the unsafe condition described previously is likely to exist or develop on other helicopters of the same type designs. Therefore, we find that notice and opportunity for prior public comment are impracticable and that good cause exists for making this amendment effective in less than 30 days. VerDate Mar<15>2010 16:38 Oct 28, 2011 Jkt 226001 Comments Invited This AD is a final rule that involves requirements affecting flight safety and was not preceded by notice and an opportunity for public comment. However, we invite you to send any written data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include the docket number FAA–2011–1041 and Directorate Identifier 2010–SW–109–AD at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of PO 00000 Frm 00016 Fmt 4700 Sfmt 4700 this AD. We will consider all comments received by the closing date and may amend this AD because of those comments. We will post all comments we receive, without change, to http:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD. Costs of Compliance We estimate that this AD affects 265 helicopters of U.S. registry. We estimate the following costs to comply with this AD: E:\FR\FM\31OCR1.SGM 31OCR1 67053 Federal Register / Vol. 76, No. 210 / Monday, October 31, 2011 / Rules and Regulations ESTIMATED COSTS Action Labor cost Inspect for S/N affectivity ................................ Remove and replace blade ............................. 2.0 hrs × $85 hr = $170 ................................. 6.0 hrs × $85 hr = $510 ................................. This cost estimate is based on the assumption that all affected helicopters will be inspected, and 35 helicopters will have a blade replaced. The manufacturer has indicated that some of the costs associated with this AD may be covered under a warranty program, but this AD has not considered this warranty program when calculating total costs on U.S. operators. 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. Parts cost Regulatory Findings 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 this AD: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Is not a ‘‘significant rule’’ under 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.

SUPPLEMENTARY INFORMATION: FOR FURTHER INFORMATION CONTACT: History DEPARTMENT OF TRANSPORTATION On July 25, 2011, the FAA published in the Federal Register a notice of proposed rulemaking to amend Class E airspace at Fayette, AL (76 FR 44285) Docket No. FAA–2011–0559. Subsequent to publication, the FAA found that the geographic coordinates needed to be adjusted. This action makes that adjustment. Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. No comments were received. Class E airspace designations are published in paragraph 6005 of FAA Order 7400.9V dated August 9, 2011, and effective September 15, 2011, which is incorporated by reference in 14 CFR 71.1. The Class E airspace designations listed in this document will be published subsequently in the Order. With the exception of editorial changes, and the changes described above, this rule is the same as that proposed in the NPRM.

ACTION: Final rule. mstockstill on DSK4VPTVN1PROD with RULES AGENCY: This action amends Class E Airspace at Fayette, AL, as the Fayette Non-Directional Beacon (NDB) has been decommissioned and new Standard Instrument Approach Procedures have been developed at Richard Arthur Field. SUMMARY: VerDate Mar<15>2010 16:38 Oct 28, 2011 Jkt 226001 This amendment to Title 14, Code of Federal Regulations (14 CFR) part 71 amends the Class E airspace extending upward from 700 feet above the surface at Fayette, AL to accommodate the new Standard Instrument Approach Procedures developed for Richard Arthur Field. The Fayette NDB has been decommissioned, and the NDB approach cancelled. The existing Class E airspace extending upward from 700 feet above the surface is being modified for the safety and management of IFR operations.

The FAA has determined that this regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current, is non-controversial and unlikely to result in adverse or negative comments. It, therefore, (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866; (2) is not a ‘‘significant rule’’ under DOT Regulatory Policies and Procedures (44 FR 11034; February 26, 1979); and (3) does not warrant preparation of a Regulatory Evaluation as the anticipated impact is so minimal. Since this is a routine matter that will only affect air traffic procedures and air navigation, it is certified that this rule, when promulgated, will not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. The FAA’s authority to issue rules regarding aviation safety is found in Title 49 of the United States Code. 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. This rulemaking is promulgated under the authority described in Subtitle VII, Part A, Subpart I, Section 40103. Under that section, the FAA is charged with prescribing regulations to assign the use of airspace necessary to ensure the safety of aircraft and the efficient use of airspace. This regulation is within the scope of that authority as it amends controlled airspace at Richard Arthur Field, Fayette, AL.

supersedes an existing airworthiness directive (AD) for the specified 
Bell Helicopter Textron, Inc. (BHT) Model helicopters with certain tail 
rotor blades (blades). The superseded AD requires, before further 
flight, replacing certain blades with airworthy blades. This AD retains 
the requirements of the superseded AD but adds new blade part numbers 
(P/Ns) and serial numbers (S/Ns) to the applicability. This AD was 
prompted by another incident in which the blade tip weight separated 
from a blade during flight, causing vibration. This incident led to the 
determination that additional blades could be affected, and should be 
added to the applicability. We are issuing this AD to prevent loss of 
the blade tip weight, loss of a blade, and subsequent loss of control 
of the helicopter.

DATES: This AD is effective November 15, 2011 to all persons except 
those persons to whom it was made immediately effective by Emergency AD 
2010-26-52, issued on December 10, 2010, which contained the 
requirements of this amendment.
    We must receive comments on this AD by December 30, 2011.

SUPPLEMENTARY INFORMATION: 

Discussion

    We are publishing in the Federal Register an amendment adopting 
Emergency AD 2010-26-52, issued December 10, 2010 (EAD 2010-26-52), 
which was sent to all known owners and operators of BHT Model 204B, 
205A, 205A-1, 205B, 210, 212, 412, 412CF, and 412EP helicopters with 
certain blades installed. EAD 2010-26-52 supersedes AD 2007-19-53, 
Amendment 39-15265 (72 FR 65224, November 20, 2007) issued October 31, 
2007 (AD 2007-19-53). AD 2007-19-53 required, before further flight, 
replacing certain blades with airworthy blades. That action was 
prompted by three reports of blade tip weights being slung from the 
blades during flights, causing significant vibration. We issued AD 
2007-19-53 on a limited number of blades to address this unsafe 
condition, which could result in the loss of the blade tip weight, loss 
of a blade, and subsequent loss of control of the helicopter.

Actions Since AD was Issued

    Since we issued AD 2007-19-53, another incident occurred in which 
the blade tip weight separated from a blade during flight, causing 
vibration. This incident led to the determination that additional 
blades could be affected and these blade numbers should be added to the 
applicability section of the AD. We issued superseding EAD 2010-26-52 
which retains the same requirements of AD 2007-19-53, but adds new 
blade P/Ns and S/Ns to the applicability.

Relevant Service Information

    We have reviewed the following revised BHT Alert Service Bulletins 
(ASBs), all dated November 22, 2010 except for ASB No. 204-07-61. Each 
ASB contains a Rotor Blades Inc. (RBI) letter that adds blade P/Ns and 
S/Ns to the RBI list.
     No. 204-07-61, Revision A, dated September 19, 2007, for 
Model 204 helicopters;
     No. 205-07-95, Revision B, for Model 205 helicopters;
     No. 205B-07-46, Revision B, for Model 205B helicopters;
     No. 212-07-125, Revision B, for Model 212 helicopters;
     No. 412CF-07-30, Revision B, for Model 412CF helicopters;
     No. 412-07-123, Revision B, for Model 412 and 412EP 
helicopters.

FAA's Determination

    We are issuing this AD because we evaluated all relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop on other helicopters of the same type 
designs. We have also determined that Emergency AD 2010-26-52 contained 
an incorrect Alert Service Bulletin (ASB) number for the Model 412CF 
helicopters in the preamble discussion. Therefore, we are making a 
change to this AD to correct the ASB number. We have also made other 
minor editorial changes to this AD, including reorganizing the 
Applicability table. We have determined that these changes do not 
increase the economic burden on any AD operator nor do they increase 
the scope of the AD.

AD Requirements

    This AD requires, before further flight, unless already 
accomplished, replacing any affected blade with an airworthy blade. An 
airworthy blade is one that has a P/N and S/N not included in the 
Applicability section of this AD. Affected blades are those having a P/
N and S/N as follows:

------------------------------------------------------------------------
                 Part No.                            Serial No.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The short compliance time of before further flight justifies 
waiving notice and comment prior to adoption of this rule because the 
unsafe condition described previously is likely to exist or develop on 
other helicopters of the same type designs. Therefore, we find that 
notice and opportunity for prior public comment are impracticable and 
that good cause exists for making this amendment effective in less than 
30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety and was not preceded by notice and an opportunity for public 
comment. However, we invite you to send any written data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include the docket number FAA-2011-1041 and 
Directorate Identifier 2010-SW-109-AD at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this AD. We will 
consider all comments received by the closing date and may amend this 
AD because of those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD affects 265 helicopters of U.S. registry. 
We estimate the following costs to comply with this AD:

[[Page 67053]]



                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
                Action                         Labor cost           Parts cost      helicopter       operators
----------------------------------------------------------------------------------------------------------------
Inspect for S/N affectivity...........  2.0 hrs x $85 hr = $170.             $ 0            $170         $45,050
Remove and replace blade..............  6.0 hrs x $85 hr = $510.          38,000          38,510       1,347,850
----------------------------------------------------------------------------------------------------------------

    This cost estimate is based on the assumption that all affected 
helicopters will be inspected, and 35 helicopters will have a blade 
replaced. The manufacturer has indicated that some of the costs 
associated with this AD may be covered under a warranty program, but 
this AD has not considered this warranty program when calculating total 
costs on U.S. operators.

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

    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 this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under 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.

Note 1: The * indicates the newly added serial-numbered blades.

.Unsafe Condition

    (d) This AD was prompted by another incident in which the blade 
tip weight separated from a blade during flight, causing vibration. 
This incident led to the determination that additional blades could 
be affected and should be added to the applicability. The actions 
specified by this AD are intended to prevent loss of the blade tip 
weight, loss of a blade, and subsequent loss of control of the 
helicopter.

Compliance

    (e) Before further flight, unless accomplished previously.
    (f) Replace any affected blade with an airworthy blade. An 
airworthy blade is one that has a part number and a serial number 
that is not listed in the Applicability section of this AD.
    Note 2: Bell Helicopter Textron Alert Service Bulletin No. 204-
07-61, Revision A, dated September 19, 2007, contains additional
