Absent significant modifications to the proposed revisions requiring republication, the NRC will not initiate a second comment period on this action in the event the direct final rule is withdrawn. A significant adverse comment is a comment where the commenter explains why the rule would be inappropriate, including challenges to the rule’s underlying premise or approach, or would be ineffective or unacceptable without a change. A comment is adverse and significant if: 1. The comment opposes the rule and provides a reason sufficient to require a substantive response in a notice-andcomment process. For example, a substantive response is required when: a. The comment causes the NRC staff to reevaluate (or reconsider) its position or conduct additional analysis; b. The comment raises an issue serious enough to warrant a substantive response to clarify or complete the record; or c. The comment raises a relevant issue that was not previously addressed or considered by the NRC staff. 2. The comment proposes a change or an addition to the rule, and it is apparent that the rule would be ineffective or unacceptable without incorporation of the change or addition. 3. The comment causes the NRC staff to make a change (other than editorial) to the rule, CoC, or TS.

ACTION: Notice of proposed rulemaking (NPRM). SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain Boeing Model 747 series airplanes. This proposed AD would require replacing the power control relays for the main tank fuel boost pumps and jettison pumps, and the center tank scavenge pump, as applicable, with new relays having a ground fault interrupt (GFI) feature. The proposed AD also would require revising the maintenance program to incorporate Airworthiness Limitations (AWLs) No. 28–AWL–23 (for Model 747–100, 747–100B, 747– 100B SUD, 747–200B, 747–200C, 747– 200F, 747–300, 747SP, and 747SR series airplanes), and Nos. 28–AWL–28 and 28–AWL–29 (for Model 747–400, 747– 400D, and 747–400F series airplanes). This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent damage to the fuel pumps caused by electrical arcing that could introduce an ignition source in the fuel tank, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.

Discussion The FAA has examined the underlying safety issues involved in fuel tank explosions on several large transport airplanes, including the adequacy of existing regulations, the service history of airplanes subject to those regulations, and existing maintenance practices for fuel tank systems. As a result of those findings, we issued a regulation titled ‘‘Transport Airplane Fuel Tank System Design Review, Flammability Reduction and Maintenance and Inspection Requirements’’ (66 FR 23086, May 7, 2001). In addition to new airworthiness standards for transport airplanes and new maintenance requirements, this rule included Special Federal Aviation Regulation No. 88 (‘‘SFAR 88,’’ Amendment 21–78, and subsequent Amendments 21–82 and 21–83). Among other actions, SFAR 88 requires certain type design (i.e., type certificate (TC) and supplemental type certificate (STC)) holders to substantiate that their fuel tank systems can prevent ignition sources in the fuel tanks. This requirement applies to type design holders for large turbine-powered transport airplanes and for subsequent modifications to those airplanes. It requires them to perform design reviews and to develop design changes and maintenance procedures if their designs do not meet the new fuel tank safety standards. As explained in the preamble to the rule, we intended to adopt airworthiness directives to mandate any changes found necessary to address unsafe conditions identified as a result of these reviews. In evaluating these design reviews, we have established four criteria intended to define the unsafe conditions associated with fuel tank systems that require corrective actions. The percentage of operating time during which fuel tanks are exposed to flammable conditions is one of these criteria. The other three criteria address PO 00000 Frm 00003 Fmt 4702 Sfmt 4702 the failure types under evaluation: single failures, single failures in combination with a latent condition(s), and in-service failure experience. For all four criteria, the evaluations included consideration of previous actions taken that may mitigate the need for further action. We have determined that the actions identified in this AD are necessary to reduce the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane. As part of SFAR 88 analysis, Boeing determined that the power control relays for the main tank fuel boost pumps and jettison pumps and the center tank scavenge pump should be replaced with new relays having a ground fault interrupt (GFI) feature. The relays are located in the P414, P415, and P52 panels. The GFI feature is intended to protect the fuel pumps from damage caused from electrical arcing by removing electrical power from the pump if a ground fault is detected. Electrical arcing, if not prevented, could introduce an ignition source in the fuel tank, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane. Relevant Service Information We have reviewed Boeing Alert Service Bulletin 747–28A2261, dated February 19, 2009. The service bulletin describes procedures for replacing the relays for the main tank fuel boost pumps and jettison pumps, and the center tank scavenge pump, as applicable, with new relays having a GFI feature. The replacement also includes reworking certain wiring and doing an operational test of the fuel boost pumps and new relays. We have also reviewed the following documents, which include a repetitive inspection (test) to verify continued functionality of the GFI relays: • For Model 747–400, 747–400D, and 747–400F series airplanes: Subsection D, ‘‘AIRWORTHINESS LIMITATIONS— FUEL SYSTEMS,’’ of Boeing 747–400 Maintenance Planning Data (MPD) Document, Document D621U400–9, Section 9, Revision April 2008. Subsection D of Revision April 2008 of the MPD includes new airworthiness limitations (AWLs) 28–AWL–28 and 28–AWL–29. (These AWLs were first introduced in Revision October 2007 of the MPD document.) Incorporating these AWLs are an optional action in AD 2008–10–06, Amendment 39–15512 (73 FR 25990, May 8, 2008).

FAA’s Determination and Requirements of This Proposed AD We are proposing this AD because we evaluated all relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. This proposed AD would require accomplishing the actions specified in the service information described previously. Costs of Compliance We estimate that this proposed AD would affect 258 airplanes of U.S. registry. The following table provides the estimated costs for U.S. operators to comply with this proposed AD. TABLE—ESTIMATED COSTS Average labor rate per hour Action Work hours Replacement .................... 10 to 14 1 ..... $80 Revision of Airworthiness Limitations section. 1 .................. $80 1 Depending 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.

Authority for This Rulemaking 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, VerDate Nov<24>2008 Parts 14:31 Oct 09, 2009 Jkt 220001 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.

ACTION: Proposed rule. SUMMARY: The Commodity Futures Trading Commission (‘‘Commission’’ or ‘‘CFTC’’) is proposing to amend certain of its regulations in connection with electronic filing of financial reports and other notices (‘‘Proposal’’). The Proposal would broaden the language in the Commission’s regulations applicable to electronic filings of financial reports to clarify that, to the extent a futures commission merchant (‘‘FCM’’) submits a Form 1–FR to the Commission electronically, it may do so using any user authentication procedures established or approved by the Commission. The Proposal also would permit registrants to electronically submit filings in addition to financial reports, including an election to use a non-calendar fiscal year, requests for extensions of time to file uncertified financial reports and ‘‘early warning’’ notices required under Commission regulations. In connection with the filing of financial reports, the Commission also is proposing to specify, consistent with other requirements and existing practice, that a statement of income and loss is included as a required part of the noncertified 1–FR filings for FCMs and introducing brokers (‘‘IBs’’). The Commission also is proposing to require more immediate, but less prescriptive, documentation regarding a firm’s capital condition when a firm falls below its required minimum adjusted net capital. Finally, the Commission is proposing several other minor amendments to correct certain outdated references and to make other clarifications to existing regulations.

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Boeing Model 747 series airplanes. This proposed AD would 
require replacing the power control relays for the main tank fuel boost 
pumps and jettison pumps, and the center tank scavenge pump, as 
applicable, with new relays having a ground fault interrupt (GFI) 
feature. The proposed AD also would require revising the maintenance 
program to incorporate Airworthiness Limitations (AWLs) No. 28-AWL-23 
(for Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-
200F, 747-300, 747SP, and 747SR series airplanes), and Nos. 28-AWL-28 
and 28-AWL-29 (for Model 747-400, 747-400D, and 747-400F series 
airplanes). This proposed AD results from fuel system reviews conducted 
by the manufacturer. We are proposing this AD to prevent damage to the 
fuel pumps caused by electrical arcing that could introduce an ignition 
source in the fuel tank, which, in combination with flammable fuel 
vapors, could result in a fuel tank explosion and consequent loss of 
the airplane.

Discussion

    The FAA has examined the underlying safety issues involved in fuel 
tank explosions on several large transport airplanes, including the 
adequacy of existing regulations, the service history of airplanes 
subject to those regulations, and existing maintenance practices for 
fuel tank systems. As a result of those findings, we issued a 
regulation titled ``Transport Airplane Fuel Tank System Design Review, 
Flammability Reduction and Maintenance and Inspection Requirements'' 
(66 FR 23086, May 7, 2001). In addition to new airworthiness standards 
for transport airplanes and new maintenance requirements, this rule 
included Special Federal Aviation Regulation No. 88 (``SFAR 88,'' 
Amendment 21-78, and subsequent Amendments 21-82 and 21-83).
    Among other actions, SFAR 88 requires certain type design (i.e., 
type certificate (TC) and supplemental type certificate (STC)) holders 
to substantiate that their fuel tank systems can prevent ignition 
sources in the fuel tanks. This requirement applies to type design 
holders for large turbine-powered transport airplanes and for 
subsequent modifications to those airplanes. It requires them to 
perform design reviews and to develop design changes and maintenance 
procedures if their designs do not meet the new fuel tank safety 
standards. As explained in the preamble to the rule, we intended to 
adopt airworthiness directives to mandate any changes found necessary 
to address unsafe conditions identified as a result of these reviews.
    In evaluating these design reviews, we have established four 
criteria intended to define the unsafe conditions associated with fuel 
tank systems that require corrective actions. The percentage of 
operating time during which fuel tanks are exposed to flammable 
conditions is one of these criteria. The other three criteria address 
the failure types under evaluation: single failures, single failures in 
combination with a latent condition(s), and in-service failure 
experience. For all four criteria, the evaluations included 
consideration of previous actions taken that may mitigate the need for 
further action.
    We have determined that the actions identified in this AD are 
necessary to reduce the potential of ignition sources inside fuel 
tanks, which, in combination with flammable fuel vapors, could result 
in a fuel tank explosion and consequent loss of the airplane.
    As part of SFAR 88 analysis, Boeing determined that the power 
control relays for the main tank fuel boost pumps and jettison pumps 
and the center tank scavenge pump should be replaced with new relays 
having a ground fault interrupt (GFI) feature. The relays are located 
in the P414, P415, and P52 panels. The GFI feature is intended to 
protect the fuel pumps from damage caused from electrical arcing by 
removing electrical power from the pump if a ground fault is detected. 
Electrical arcing, if not prevented, could introduce an ignition source 
in the fuel tank, which, in combination with flammable fuel vapors, 
could result in a fuel tank explosion and consequent loss of the 
airplane.

Relevant Service Information

    We have reviewed Boeing Alert Service Bulletin 747-28A2261, dated 
February 19, 2009. The service bulletin describes procedures for 
replacing the relays for the main tank fuel boost pumps and jettison 
pumps, and the center tank scavenge pump, as applicable, with new 
relays having a GFI feature. The replacement also includes reworking 
certain wiring and doing an operational test of the fuel boost pumps 
and new relays.
    We have also reviewed the following documents, which include a 
repetitive inspection (test) to verify continued functionality of the 
GFI relays:

April 2008 of the MPD includes new airworthiness limitations (AWLs) 28-
AWL-28 and 28-AWL-29. (These AWLs were first introduced in Revision 
October 2007 of the MPD document.) Incorporating these AWLs are an 
optional action in AD 2008-10-06, Amendment 39-15512 (73 FR 25990, May

this AWL is an optional action in AD 2008-10-07, Amendment 39-15513 (73 
FR 25977, May 8, 2008).

FAA's Determination and Requirements of This Proposed AD

    We are proposing this AD because we evaluated all relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design. 
This proposed AD would require accomplishing the actions specified in 
the service information described previously.

Costs of Compliance

    We estimate that this proposed AD would affect 258 airplanes of 
U.S. registry. The following table provides the estimated costs for 
U.S. operators to comply with this proposed AD.

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.
    You can find our regulatory evaluation and the estimated costs of 
compliance in the AD Docket.
