FOR FURTHER INFORMATION CONTACT: Brian R. Hooker, Fishery Policy Analyst, 978–281–9220. SUPPLEMENTARY INFORMATION: Background The Council voted on December 13, 2006, to recommend to NMFS that a VMS requirement for Atlantic surfclam and ocean quahog fishing vessels, including Maine mahogany quahog vessels, be implemented for their respective fisheries. This action was originally approved by the Council as part of Amendment 13 to the FMP in 2003. However, the Council recommended that the Administrator, Northeast Region, NMFS (Regional Administrator) implement a VMS requirement for the fisheries when an economically viable system, tailored to meet the needs of the Atlantic surfclam and ocean quahog fishery, became available to the industry. Three VMS vendors have been approved by NMFS for use in the Northeast Region. The costs of the VMS units have decreased since 2003, so that purchase and installation costs now range from approximately $1,800 to $3,800, and recurring monthly costs range from $25 to $100. As a result of the lower costs, the Council voted in June 2005 to begin the development of a framework adjustment to require the mandatory use of VMS for surfclams and ocean quahogs. The Council held two public meetings, on October 11, 2006, and December 13, 2006, to discuss the management measures contained in FW 1 and, on December 13, 2006, the Council selected and approved the VMS management measures to submit to NMFS for approval and implementation. The Council’s approved measures included a provision to delay the effectiveness of the VMS requirement for a period of one year for the limited access permitted Maine mahogany quahog fishery.

14 CFR Part 39

[Docket No. FAA-2007-28726; Directorate Identifier 2007-NE-32-AD; 
Amendment 39-15190; AD 2007-18-10]
RIN 2120-AA64


Airworthiness Directives; General Electric Company CF6-80E1 
Series Turbofan Engines

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

ACTION: Final rule; request for comments.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
General Electric Company (GE) CF6-80E1 series turbofan engines with 
certain part number (P/N) compressor rear frames (CRFs) installed. This 
AD requires revisions to the Airworthiness Limitations Section (ALS) of 
the manufacturer's Instructions for Continued Airworthiness (ICA) and 
air carrier's approved Continued Airworthiness Maintenance Programs 
(CAMP) to include initial and repetitive eddy current inspections 
(ECIs) or fluorescent penetrant inspections (FPIs) of the affected 
CRFs. This AD results from the need to require enhanced inspections of 
the CF6-80E1 series engine CRFs for cracks. We are issuing this AD to 
prevent rupture of the CRF, which could result in an under-cowl engine 
fire.

DATES: This AD becomes effective September 26, 2007.
    We must receive any comments on this AD by November 13, 2007.

SUPPLEMENTARY INFORMATION: GE recently reassessed the original basis 
for certification of the CF6-80E1 series turbofan engine CRFs, using 
updated techniques and materials. The data revealed that the stresses 
in critical areas of the CRF are higher than originally calculated. 
This condition, if not corrected, could result in rupture of the CRF, 
possibly resulting in an under-cowl engine fire.

FAA's Determination and Requirements of This AD

    Although no airplanes that are currently registered in the United 
States use these CF6-80E1 series turbofan engines, the possibility 
exists that the engines could be used on airplanes that are registered 
in the United States in the future. The unsafe condition described 
previously is likely to exist or develop on other engines of the same 
type design. We are issuing this AD to prevent rupture of the CRF, 
which could result in an under-cowl engine fire. This AD requires 
revisions to the ALS of the manufacturer's ICA and air carrier's 
approved CAMP to include required ECIs or FPIs of those certain P/N 
CRFs, for cracks in critical areas.

FAA's Determination of the Effective Date

    Since there are currently no domestic operators of this engine 
model, notice and opportunity for public comment before issuing this AD 
are unnecessary. A situation exists that allows the immediate adoption 
of this regulation.

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 us any written relevant data, 
views, or arguments regarding this AD. Send your comments to an address 
listed under ADDRESSES. Include ``AD Docket No. FAA-2007-28726; 
Directorate Identifier 2007-NE-32-AD'' in the subject line of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of the rule that might 
suggest a need to modify it.
    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 with FAA 
personnel concerning this AD. Using the search function of the DMS Web 
site, anyone can find and read the comments in any of our dockets, 
including the name of the individual who sent the comment (or signed 
the comment on behalf of an association, business, labor union, etc).

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 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 summary of the costs to comply with this AD and 
placed it in the AD Docket. You may get a copy of this summary at the 
address listed under ADDRESSES.

2007-18-10 General Electric Company: Amendment 39-15190. Docket No. 
FAA-2007-28726; Directorate Identifier 2007-NE-32-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective 
September 26, 2007.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to General Electric Company (GE) CF6-80E1A1, 
CF6-80E1A2, CF6-80E1A3, CF6-80E1A4, and CF6-80E1A4/B model turbofan 
engines with compressor rear frame (CRF) part numbers (P/Ns) 
1520M26G03/G06/G08/G11/G12 installed. These engines are installed 
on, but not limited to, Airbus Industrie A330 series airplanes.

Unsafe Condition

    (d) This AD results from the need to require enhanced 
inspections of the CF6-80E1 series turbofan engine CRFs, for cracks. 
We are issuing this AD to prevent rupture of the CRF, which could 
result in an under-cowl engine fire.

Compliance

    (e) Within the next 30 days after the effective date of this AD, 
revise GE's Instructions for Continued Airworthiness ALS, and for 
air carrier operations, revise the approved continuous airworthiness 
maintenance program, by adding the information in Table 1 and in 
paragraphs (f) through (i) of this AD.

Determining CSN of the Compressor Rear Frame

    (h) Air carriers and operators must use engine operating records 
to determine the CSN of the compressor rear frame. If the number of 
cycles accumulated since new cannot be established, inspect the CRF 
within 300 cycles-in-service after the effective date of this AD.
    (i) For compressor rear frames that have operated in multiple 
engine models or thrust ratings, information on correct cycle 
counting can be found in Method 1 or Method 2 of CF6-80E1 Engine 
Manual No. GEK 99376, Section 05-11-00, LIFE LIMITS OF ENGINE 
ROTATING PARTS.

Definition

    (j) For the purposes of this AD, piece-part level means that the 
CRF is removed and disassembled using the disassembly instructions 
in GE's engine manual.

Alternative Methods of Compliance

    (k) You must perform these mandatory inspections using the ALS 
of the Instructions for Continued Airworthiness and the applicable 
Engine Manual unless you receive approval to use an alternative 
method of compliance under paragraph (l) of this AD. Section 43.16 
of the Federal Aviation Regulations (14 CFR 43.16) may not be used 
to approve alternative methods of compliance or adjustments to the 
times in which these inspections must be performed.
    (l) The Manager, Engine Certification Office, has the authority 
to approve alternative methods of compliance for this AD if 
requested using the procedures found in 14 CFR 39.19.
