ACTION: Notice of proposed rulemaking (NPRM). AGENCY: SUMMARY: The FAA proposes to supersede an existing airworthiness directive (AD) for General Electric Company (GE) CF34–10E series turbofan engines. That AD currently requires removing the fuel inlet strainer from main fuel pump (MFP) part number (P/N) 2043M12P03, installing a certain replacement flange as an interim repair, remarking the MFP to P/N 2043M12P04, and performing initial and repetitive visual inspections of the main fuel filter. This proposed AD would require removing MFPs, P/N 2043M12P03 and 2043M12P04 from service and installing an improved MFP with a different P/N. PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 1949 This proposed AD results from GE determining that the cause of MFP fuel strainer failure is a design problem with the strainer.

Comments will be available in the AD docket shortly after the DMS receives them. Discussion On September 21, 2006, we issued AD 2006–20–06, Amendment 39–14775 (71 FR 60663, October 16, 2006). That AD requires removing the MFP inlet strainer from the MFPs, installing a certain replacement flange as an interim repair, remarking the MFP to P/N 2043M12P04, and performing initial and repetitive visual inspections of the main fuel filter. That AD was the result of three reports of release of the tripod support legs on the MFP inlet strainer, leading to engine in-flight shutdown. That condition, if not corrected, could result in engine inflight shutdown due to MFP malfunctions. mstockstill on PROD1PC61 with PROPOSALS Actions Since AD 2006–20–06 Was Issued Since AD 2006–20–06 was issued, GE determined that the cause of MFP fuel inlet strainer failure is a design problem with the strainers installed in the MFPs. GE has introduced MFP P/N 2043M12P05, which has a more robust design fuel inlet strainer. FAA’s Determination and Requirements of the Proposed AD We have evaluated all pertinent information and identified an unsafe condition that is likely to exist or develop on other products of this same type design. For that reason, we are proposing this AD, which would require removing MFPs, P/N 2043M12P03 and 2043M12P04 from service and installing an improved MFP, not later than April 30, 2007. VerDate Aug<31>2005 13:17 Jan 16, 2007 Jkt 211001 Costs of Compliance We estimate that this proposed AD would affect 50 CF34–10E series turbofan engines installed on airplanes of U.S. registry. We also estimate that it would take about 3 work-hours per engine to perform the proposed actions, and that the average labor rate is $80 per work-hour. Required parts would cost about $4,226 per engine to upgrade the MFP to a different P/N to make it serviceable. Based on these figures, we estimate the total upgrade cost of the proposed AD to U.S. operators to be $223,300. 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 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 that the 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. Would 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. See the ADDRESSES section for a location to examine the regulatory evaluation.

SUPPLEMENTARY INFORMATION: DATES: I. Background (Regulatory Authorities) The Federal Food, Drug, and Cosmetic Act (the act) (21 U.S.C. 301 et. seq.), as amended by the Medical Device PO 00000 Frm 00006 Fmt 4702 Sfmt 4702 1951 Amendments of 1976 (the 1976 amendments) (Public Law 94–295), the Safe Medical Devices Act of 1990 (the SMDA) (Public Law 101–629), and the Food and Drug Administration Modernization Act of 1997 (FDAMA) (Public Law 105–115), established a comprehensive system for the regulation of medical devices intended for human use. Section 513 of the act (21 U.S.C. 360c) established three categories (classes) of devices, depending on the regulatory controls needed to provide reasonable assurance of their safety and effectiveness. The three categories of devices are class I (general controls), class II (special controls), and class III (premarket approval). Under section 513 of the act, devices that were in commercial distribution before May 28, 1976 (the date of enactment of the 1976 amendments), generally referred to as preamendments devices, are classified after FDA has: (1) Received a recommendation from a device classification panel (an FDA advisory committee); (2) published the panel’s recommendation for comment, along with a proposed regulation classifying the device; and (3) published a final regulation classifying the device. FDA has classified most preamendments devices under these procedures. Devices that were not in commercial distribution prior to May 28, 1976, generally referred to as postamendments devices, are classified automatically by statute (section 513(f) of the act into class III without any FDA rulemaking process. Those devices remain in class III and require premarket approval, unless and until the device is reclassified into class I or II or FDA issues an order finding the device to be substantially equivalent, under section 513(i) of the act, to a predicate device that does not require premarket approval. The agency determines whether new devices are substantially equivalent to predicate devices by means of premarket notification procedures in section 510(k) of the act (21 U.S.C. 360(k)) and part 807 of the regulations (21 CFR part 807). Reclassification of classified postamendments devices is governed by section 513(f)(3) of the act. This section provides that FDA may initiate the reclassification of a device classified into class III under section 513(f)(1) of the act, or the manufacturer or importer of a device may petition the Secretary of Health and Human Services (the Secretary) for the issuance of an order classifying the device in class I or class II. FDA’s regulations in 21 CFR 860.134 set forth the procedures for the filing and review of a petition for E:\FR\FM\17JAP1.SGM 17JAP1

Airworthiness Directives; General Electric Company CF34-10E 
Series Turbofan Engines

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to supersede an existing airworthiness 
directive (AD) for General Electric Company (GE) CF34-10E series 
turbofan engines. That AD currently requires removing the fuel inlet 
strainer from main fuel pump (MFP) part number (P/N) 2043M12P03, 
installing a certain replacement flange as an interim repair, remarking 
the MFP to P/N 2043M12P04, and performing initial and repetitive visual 
inspections of the main fuel filter. This proposed AD would require 
removing MFPs, P/N 2043M12P03 and 2043M12P04 from service and 
installing an improved MFP with a different P/N. This proposed AD 
results from GE determining that the cause of MFP fuel strainer failure 
is a design problem with the strainer. We are proposing this AD to 
prevent engine in-flight shutdown due to MFP malfunctions.

DATES: We must receive any comments on this proposed AD by March 19, 
2007.

Discussion

    On September 21, 2006, we issued AD 2006-20-06, Amendment 39-14775 
(71 FR 60663, October 16, 2006). That AD requires removing the MFP 
inlet strainer from the MFPs, installing a certain replacement flange 
as an interim repair, remarking the MFP to P/N 2043M12P04, and 
performing initial and repetitive visual inspections of the main fuel 
filter. That AD was the result of three reports of release of the 
tripod support legs on the MFP inlet strainer, leading to engine in-
flight shutdown. That condition, if not corrected, could result in 
engine in-flight shutdown due to MFP malfunctions.

Actions Since AD 2006-20-06 Was Issued

    Since AD 2006-20-06 was issued, GE determined that the cause of MFP 
fuel inlet strainer failure is a design problem with the strainers 
installed in the MFPs. GE has introduced MFP P/N 2043M12P05, which has 
a more robust design fuel inlet strainer.

FAA's Determination and Requirements of the Proposed AD

    We have evaluated all pertinent information and identified an 
unsafe condition that is likely to exist or develop on other products 
of this same type design. For that reason, we are proposing this AD, 
which would require removing MFPs, P/N 2043M12P03 and 2043M12P04 from 
service and installing an improved MFP, not later than April 30, 2007.

Costs of Compliance

    We estimate that this proposed AD would affect 50 CF34-10E series 
turbofan engines installed on airplanes of U.S. registry. We also 
estimate that it would take about 3 work-hours per engine to perform 
the proposed actions, and that the average labor rate is $80 per work-
hour. Required parts would cost about $4,226 per engine to upgrade the 
MFP to a different P/N to make it serviceable. Based on these figures, 
we estimate the total upgrade cost of the proposed AD to U.S. operators 
to be $223,300.

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 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 that the 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. Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria

read as follows:

General Electric Company: Docket No. FAA-2006-25896; Directorate 
Identifier 2006-NE-33-AD.
