You can find out more about SBREFA on the Internet at http://www.faa.gov/ regulations_policies/rulemaking/ sbre_act/. International Trade Impact Assessment The Trade Agreements Act of 1979 (Pub. L. 96–39) prohibits Federal agencies from establishing any standards or engaging in related activities that create unnecessary obstacles to the foreign commerce of the United States. Legitimate domestic objectives, such as safety, are not considered unnecessary obstacles. The statute also requires consideration of international standards and, where appropriate, that they be the basis for U.S. standards. The FAA has assessed the potential effect of this final rule and determined it would promote international trade by reducing the cost of export airworthiness approvals for Class II products (major components) and Class III products (parts and components). Regulations That Significantly Affect Energy Supply, Distribution, or Use The FAA has analyzed this final rule under Executive Order 13211, Actions Concerning Regulations that Significantly Affect Energy Supply, Distribution, or Use (May 18, 2001). We have determined that it is not a ‘‘significant energy action’’ under the executive order because it is not a ‘‘significant regulatory action’’ under Executive Order 12866, and it is not likely to have a significant adverse effect on the supply, distribution, or use of energy.

Small Business Regulatory Enforcement Fairness Act The Small Business Regulatory Enforcement Fairness Act (SBREFA) of 1996 requires FAA to comply with small entity requests for information or advice about compliance with statutes and regulations within its jurisdiction. If you are a small entity and you have a question regarding this document, you RIN 2120–AA64 rfrederick on PROD1PC67 with RULES Unfunded Mandates Assessment Title II of the Unfunded Mandates Reform Act of 1995 (Pub. L. 104–4) requires each Federal agency to prepare a written statement assessing the effects of any Federal mandate in a proposed or final agency rule that may result in an expenditure of $100 million or more (adjusted annually for inflation with the base year 1995) in any one year by State, local, and tribal governments, in the aggregate, or by the private sector; such a mandate is deemed to be a ‘‘significant regulatory action.’’ The FAA currently uses an inflation-adjusted value of $128.1 million. This final rule does not contain such a mandate. The requirements of Title II do not apply. Executive Order 13132, Federalism The FAA has analyzed this final rule under the principles and criteria of Executive Order 13132, Federalism. We determined that this action will not have a substantial direct effect on the States, or the relationship between the national Government and the States, or on the distribution of power and responsibilities among the various levels of government, and, therefore, does not have federalism implications.

AGENCY: E:\FR\FM\13NOR1.SGM 13NOR1 Federal Register / Vol. 72, No. 218 / Tuesday, November 13, 2007 / Rules and Regulations SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all Boeing Model 707 airplanes and Model 720 and 720B series airplanes. This AD requires accomplishing an airplane survey to define the configuration of certain system installations, and repair of any discrepancy found. This AD also requires modifying the fuel system by installing lightning protection for the fuel quantity indication system (FQIS), ground fault relays for the fuel boost pumps, and additional power relays for the center tank fuel pumps and uncommanded on-indication lights at the flight engineer’s panel. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent certain failures of the fuel pumps or FQIS, which could result in a potential ignition source inside the fuel tank, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.

SUPPLEMENTARY INFORMATION: Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to all Boeing Model 707 airplanes and Model 720 and 720B series airplanes. That NPRM was published in the Federal Register on August 1, 2007 (72 FR 41958). That NPRM proposed to VerDate Aug<31>2005 14:06 Nov 09, 2007 Jkt 214001 require accomplishing an airplane survey to define the configuration of certain system installations, and repair of any discrepancy found. That NPRM proposed to also require modifying the fuel system by installing lightning protection for the fuel quantity indication system, ground fault relays for the fuel boost pumps, and additional power relays for the center tank fuel pumps and uncommanded onindication lights at the flight engineer’s panel. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the single comment received. The commenter, Boeing, supports the NPRM. Conclusion We have carefully reviewed the available data, including the comment received, and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance There are about 185 airplanes of the affected design in the worldwide fleet. This AD affects about 52 airplanes of U.S. registry. The required survey takes about 20 work hours per airplane, at an average labor rate of $80 per work hour. Based on these figures, the estimated cost of the survey for U.S. operators is $83,200, or $1,600 per airplane. Because the manufacturer has not yet developed a modification commensurate with the actions specified by this AD, we cannot provide specific information regarding the required number of work hours or the cost of parts to do the required modification. In addition, modification costs will likely vary depending on the operator and the airplane configuration. The compliance time of 72 months should provide ample time for the development, approval, and installation of an appropriate modification. Based on similar modifications accomplished previously on other airplane models, however, we can reasonably estimate that the modification may require as many as 420 work hours per airplane, at an average labor rate of $80 per work hour. Required parts may cost up to $185,000 per airplane. Based on these figures, the estimated cost of the modification for U.S. operators may cost up to $11,367,200, or $218,600 per airplane. PO 00000 Frm 00019 Fmt 4700 Sfmt 4700 63801 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 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 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); 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 AD and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation.

AGENCY: SUMMARY: Pursuant to section 343(a) of the Trade Act of 2002 and implementing regulations, truck carriers and other eligible parties are required to transmit advance electronic truck cargo information to Customs and Border Protection (CBP) through a CBPapproved electronic data interchange. In a previous document, CBP designated the Automated Commercial Environment (ACE) Truck Manifest PO 00000 Frm 00023 Fmt 4700 Sfmt 4700 63805 System as the approved interchange and announced that the requirement that advance electronic cargo information be transmitted through ACE would be phased in by groups of ports of entry. This document announces that at all land border ports in the state of Alaska truck carriers will be required to file electronic manifests through the ACE Truck Manifest System. Trucks entering the United States through land border ports of entry in the state of Alaska will be required to transmit the advance information through the ACE Truck Manifest system effective February 11, 2008.

SUPPLEMENTARY INFORMATION: Background Section 343(a) of the Trade Act of 2002, as amended (the Act; 19 U.S.C. 2071 note), required that CBP promulgate regulations providing for the mandatory transmission of electronic cargo information by way of a CBPapproved electronic data interchange (EDI) system before the cargo is brought into or departs the United States by any mode of commercial transportation (sea, air, rail or truck). The cargo information required is that which is reasonably necessary to enable high-risk shipments to be identified for purposes of ensuring cargo safety and security and preventing smuggling pursuant to the laws enforced and administered by CBP. On December 5, 2003, CBP published in the Federal Register (68 FR 68140) a final rule to effectuate the provisions of the Act. In particular, a new section 123.92 (19 CFR 123.92) was added to the regulations to implement the inbound truck cargo provisions. Section 123.92 describes the general requirement that, in the case of any inbound truck required to report its arrival under section 123.1(b), if the truck will have commercial cargo aboard, CBP must electronically receive certain information regarding that cargo through a CBP-approved EDI system no later than 1 hour prior to the carrier’s reaching the first port of arrival in the United States. For truck carriers arriving with shipments qualified for clearance under the FAST (Free and Secure Trade) program, section 123.92 provides that CBP must electronically receive such cargo information through the CBPapproved EDI system no later than 30 minutes prior to the carrier’s reaching the first port of arrival in the United States.

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all 
Boeing Model 707 airplanes and Model 720 and 720B series airplanes. 
This AD requires accomplishing an airplane survey to define the 
configuration of certain system installations, and repair of any 
discrepancy found. This AD also requires modifying the fuel system by 
installing lightning protection for the fuel quantity indication system 
(FQIS), ground fault relays for the fuel boost pumps, and additional 
power relays for the center tank fuel pumps and uncommanded on-
indication lights at the flight engineer's panel. This AD results from 
fuel system reviews conducted by the manufacturer. We are issuing this 
AD to prevent certain failures of the fuel pumps or FQIS, which could 
result in a potential ignition source inside the fuel tank, which, in 
combination with flammable fuel vapors, could result in a fuel tank 
explosion and consequent loss of the airplane.

DATES: This AD becomes effective December 18, 2007.

SUPPLEMENTARY INFORMATION: 

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that would apply to all Boeing Model 707 
airplanes and Model 720 and 720B series airplanes. That NPRM was 
published in the Federal Register on August 1, 2007 (72 FR 41958). That 
NPRM proposed to require accomplishing an airplane survey to define the 
configuration of certain system installations, and repair of any 
discrepancy found. That NPRM proposed to also require modifying the 
fuel system by installing lightning protection for the fuel quantity 
indication system, ground fault relays for the fuel boost pumps, and 
additional power relays for the center tank fuel pumps and uncommanded 
on-indication lights at the flight engineer's panel.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the single comment received. 
The commenter, Boeing, supports the NPRM.

Conclusion

    We have carefully reviewed the available data, including the 
comment received, and determined that air safety and the public 
interest require adopting the AD as proposed.

Costs of Compliance

    There are about 185 airplanes of the affected design in the 
worldwide fleet. This AD affects about 52 airplanes of U.S. registry.
    The required survey takes about 20 work hours per airplane, at an 
average labor rate of $80 per work hour. Based on these figures, the 
estimated cost of the survey for U.S. operators is $83,200, or $1,600 
per airplane.
    Because the manufacturer has not yet developed a modification 
commensurate with the actions specified by this AD, we cannot provide 
specific information regarding the required number of work hours or the 
cost of parts to do the required modification. In addition, 
modification costs will likely vary depending on the operator and the 
airplane configuration. The compliance time of 72 months should provide 
ample time for the development, approval, and installation of an 
appropriate modification.
    Based on similar modifications accomplished previously on other 
airplane models, however, we can reasonably estimate that the 
modification may require as many as 420 work hours per airplane, at an 
average labor rate of $80 per work hour. Required parts may cost up to 
$185,000 per airplane. Based on these figures, the estimated cost of 
the modification for U.S. operators may cost up to $11,367,200, or 
$218,600 per airplane.

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 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 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); 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 AD and placed it in the AD docket. See the ADDRESSES 
section for a location to examine the regulatory evaluation.

Sec.  39.13  [Amended]

0
2. The Federal Aviation Administration (FAA) amends Sec.  39.13 by 
adding the following new airworthiness directive (AD):

2007-23-12 Boeing: Amendment 39-15258. Docket No. FAA-2007-28828; 
Directorate Identifier 2007-NM-010-AD.

Effective Date

    (a) This AD becomes effective December 18, 2007.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to all Boeing Model 707-100 long body, -200, 
-100B long body, and -100B short body series airplanes; and Model 
707-300, -300B, -300C, and -400 series airplanes; and Model 720 and 
720B series airplanes; certificated in any category.

Unsafe Condition

    (d) This AD results from fuel system reviews conducted by the 
manufacturer. We are issuing this AD to prevent certain failures of 
the fuel pumps or fuel quantity indication system (FQIS), which 
could result in a potential ignition source inside the fuel tank, 
which, in combination with flammable fuel vapors, could result in 
fuel tank explosion and consequent loss of the airplane.

Compliance

    (e) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.

Airplane Survey

    (f) Within 12 months after the effective date of this AD: 
Conduct an airplane survey that defines the configuration of system 
installations for the wing leading edges, wing-to-body area, 
electrical equipment bay, flight deck, and FQIS using a method 
approved in accordance with the procedures specified in paragraph 
(h)(1) of this AD. If any discrepancy is detected, repair before 
further flight using a method approved in accordance with the 
procedures specified in paragraph (h)(1) of this AD. Submit the 
survey results to the Manager, Seattle Aircraft Certification Office 
(ACO), FAA, 1601 Lind Avenue SW., Renton, Washington 98057-3356, at 
the applicable time specified in paragraph (f)(1) or (f)(2) of this 
AD. The report must include the survey results (e.g., photographs 
and sketches, part numbers of FQIS components and fuel pumps, and 
the actual configuration of FQIS and the fuel pump control systems), 
a description of any discrepancy found, the airplane serial number, 
and the number of landings and flight hours on the airplane. Under 
the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et 
seq.), the Office of Management and Budget (OMB) has approved the 
information collection requirements contained in this AD and has 
assigned OMB Control Number 2120-0056.
    (1) If the survey was done after the effective date of this AD: 
Submit the report within 30 days after the survey.
    (2) If the survey was done before the effective date of this AD: 
Submit the report within 30 days after the effective date of this 
AD.

    Note 1: For the purposes of this AD, ``discrepancy'' is defined 
as any wear or deterioration (e.g., damage, fluid leaks, corrosion, 
cracking, or system failures) that might prevent the airplane from 
being in an airworthy condition.

Modification of Fuel System

    (g) Within 72 months after the effective date of this AD: Modify 
the fuel system as specified in paragraphs (g)(1), (g)(2), and 
(g)(3) of this AD, using a method approved in accordance with the 
procedures specified in paragraph (h)(1) of this AD.
    (1) Replace the FQIS wire bundle along the leading edge of the 
left and right wings with a new wire bundle that has a lightning 
shield that is separated from other wiring.
    (2) Replace each fuel pump relay with a ground fault interrupter 
relay.
    (3) Install redundant power relays for the center tank fuel 
pumps and uncommanded on-indication lights at the flight engineer's 
panel.

Alternative Methods of Compliance (AMOCs)

    (h)(1) The Manager, Seattle ACO has the authority to approve 
AMOCs for this AD, if requested in accordance with the procedures 
found in 14 CFR 39.19.
    (2) To request a different method of compliance or a different 
compliance time for this AD, follow the procedures in 14 CFR 39.19. 
Before using any approved AMOC on any airplane to which the AMOC 
applies, notify your appropriate principal inspector (PI) in the FAA 
Flight Standards District Office (FSDO), or lacking a PI, your local 
FSDO.
