ACTION: Petition for rulemaking; consideration of petition. AGENCY: On November 2, 2001 (66 FR 55603), the Nuclear Regulatory Commission (NRC) published for public comment a petition for rulemaking (PRM) filed by Scott Portzline, Three Mile Island Alert. The petitioner requested that the NRC regulations governing physical protection of plants and materials be amended to require NRC licensees to post at least one armed guard at each entrance to the ‘‘owner controlled areas’’ (OCAs) surrounding all U.S. nuclear power plants. The petitioner states that this should be accomplished by adding armed site protection officers (SPOs) to the security forces—not by simply moving SPOs from their protected area (PA) posts to the OCA entrances. The petitioner believes that its proposed amendment would provide an additional layer of security that would complement existing measures against radiological sabotage and would be consistent with the long-standing principle of defensein-depth. cprice-sewell on PROD1PC66 with PROPOSALS SUMMARY: VerDate Aug<31>2005 15:47 Jan 04, 2007 Jkt 211001 This document informs the public that PRM–73–11 and public comments received in response to the above notice will be considered in a proposed rulemaking, ‘‘Power Reactor Security Requirements,’’ published in the Federal Register on October 26, 2006 (71 FR 62664). This rulemaking proposes extensive revisions to the NRC regulations in 10 CFR parts 50, 72, and 73 that address security requirements for nuclear power reactor licensees and certain materials licensees. The comment period on that proposed rule expires on February 23, 2007. Because the public has already had opportunity to comment on PRM–73–11, the NRC is requesting that comments focus on the proposed rule provisions in light of the subject PRM. Refer to the preamble of the proposed rule for instructions on how to provide comments.

SUPPLEMENTARY INFORMATION: Streamlined Issuance of AD The FAA is implementing a new process for streamlining the issuance of ADs related to MCAI. The streamlined process will allow us to adopt MCAI safety requirements in a more efficient manner and will reduce safety risks to E:\FR\FM\05JAP1.SGM 05JAP1 482 Federal Register / Vol. 72, No. 3 / Friday, January 5, 2007 / Proposed Rules the public. This process continues to follow all FAA AD issuance processes to meet legal, economic, Administrative Procedure Act, and Federal Register requirements. We also continue to meet our technical decision-making responsibilities to identify and correct unsafe conditions on U.S.-certificated products. This proposed AD references the MCAI and related service information that we considered in forming the engineering basis to correct the unsafe condition. The proposed AD contains text copied from the MCAI and for this reason might not follow our plain language principles. cprice-sewell on PROD1PC66 with PROPOSALS Comments Invited We invite you to send any written relevant data, views, or arguments about this proposed AD. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA–2006–26496; Directorate Identifier 2006–CE–81–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD because of those comments. We will post all comments we receive, without change, to https:// dms.dot.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion The Civil Aviation Authority of New Zealand, which is the aviation authority for New Zealand, has issued AD DCA/ R2000/38, dated June 29, 2006 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states that there have been instances indicating that production aircraft may not have a metal barrier between the cabin and the fuel tank bay. Lack of a barrier could allow flammable fuel vapors to enter the cabin. The MCAI requires that, to ensure that the aircraft is in compliance with 14 CFR 23.967(d), inspect the aircraft to determine if a metal barrier is installed behind the seats and, if not installed, to manufacture and install a barrier. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Alpha Aviation Design Limited has issued Alpha Aviation Service Bulletin AA–SB–28–001, dated July 10, 2006. The actions described in this service VerDate Aug<31>2005 15:47 Jan 04, 2007 Jkt 211001 information are intended to correct the unsafe condition identified in the MCAI. FAA’s Determination and Requirements of the Proposed AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with this State of Design Authority, 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 and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. Differences Between This Proposed AD and the MCAI or Service Information We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information. We might also have proposed different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are described in a separate paragraph of the proposed AD. These requirements, if ultimately adopted, will take precedence over the actions copied from the MCAI. Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 10 products of U.S. registry. We also estimate that it would take about 3 work-hours per product to comply with the proposed AD. The average labor rate is $80 per work-hour. Required parts would cost about $300 per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these costs. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $5,400, or $540 per product. Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I, PO 00000 Frm 00012 Fmt 4702 Sfmt 4702 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 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

Discussion

    The Civil Aviation Authority of New Zealand, which is the aviation 
authority for New Zealand, has issued AD DCA/R2000/38, dated June 29, 
2006 (referred to after this as ``the MCAI''), to correct an unsafe 
condition for the specified products. The MCAI states that there have 
been instances indicating that production aircraft may not have a metal 
barrier between the cabin and the fuel tank bay. Lack of a barrier 
could allow flammable fuel vapors to enter the cabin. The MCAI requires 
that, to ensure that the aircraft is in compliance with 14 CFR 
23.967(d), inspect the aircraft to determine if a metal barrier is 
installed behind the seats and, if not installed, to manufacture and 
install a barrier. You may obtain further information by examining the 
MCAI in the AD docket.

Relevant Service Information

    Alpha Aviation Design Limited has issued Alpha Aviation Service 
Bulletin AA-SB-28-001, dated July 10, 2006. The actions described in 
this service information are intended to correct the unsafe condition 
identified in the MCAI.

FAA's Determination and Requirements of the Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with this State of Design Authority, 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 and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design.

Differences Between This Proposed AD and the MCAI or Service 
Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might also have proposed different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
described in a separate paragraph of the proposed AD. These 
requirements, if ultimately adopted, will take precedence over the 
actions copied from the MCAI.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 10 products of U.S. registry. We also estimate that 
it would take about 3 work-hours per product to comply with the 
proposed AD. The average labor rate is $80 per work-hour. Required 
parts would cost about $300 per product. Where the service information 
lists required parts costs that are covered under warranty, we have 
assumed that there will be no charge for these costs. As we do not 
control warranty coverage for affected parties, some parties may incur 
costs higher than estimated here. Based on these figures, we estimate 
the cost of the proposed AD on U.S. operators to be $5,400, or $540 per 
product.

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 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.

held by APEX Aircraft and AVIONS PIERRE ROBIN): Docket No. FAA-2006-
26496; Directorate Identifier 2006-CE-81-AD.

Comments Due Date

    (a) We must receive comments by February 5, 2007.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Model R2160 airplanes, serial numbers 001 
through 378, certificated in any category.

Reason

    (d) The mandatory continuing airworthiness information (MCAI) 
states that there have been instances indicating that production 
aircraft may not have a metal barrier between the cabin and the fuel 
tank bay. Lack of a barrier could allow flammable fuel vapors to 
enter the cabin. The MCAI requires that, to ensure that the aircraft 
is in compliance with 14 CFR 23.967(d), inspect the aircraft to 
determine if a metal barrier is installed behind the seats and, if 
not installed, to manufacture and install a barrier.

Actions and Compliance

    (e) Unless already done, do the following actions within the 
next 100 hours time-in-service or within 6 months of the effective 
date of this AD, whichever occurs first.
    (1) Inspect the aircraft to determine if a metal barrier is 
installed behind the seats per Alpha Aviation Service Bulletin AA-
SB-28-001, dated July 10, 2006.
    (2) If a metal barrier is installed per Alpha Aviation Service 
Bulletin AA-SB-28-001, dated July 10, 2006, and (e)(1) of this AD 
then no further action is required.
    (3) If a metal barrier is not installed, manufacture and install 
a barrier per Alpha Aviation Service Bulletin AA-SB-28-001, dated 
July 10, 2006 and Alpha Aviation Drawing No. 60-53-119 (page 3 of 3 
of the Service Bulletin).

is airworthy before it is returned to service.
    (3) Reporting Requirements: For any reporting requirement in 
this AD, under the provisions of the Paperwork Reduction Act (44 
U.S.C. 3501 et seq.), the Office of Management and Budget (OMB) has
