ACTION: Final rule. AGENCY: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for GE CF6–80C2B5F turbofan engines. This AD requires removing certain part number (P/N) high-pressure compressor rotor (HPCR) stages 11–14 spool/shafts before they exceed a new, reduced life limit. This AD results from an internal GE audit that compared the life limited parts certification documentation to the airworthiness limitations section (ALS) of the instructions for continuing airworthiness (ICA). We are issuing this AD to prevent HPCR stages 11–14 spool/ shaft fatigue cracks caused by exceeding the life limit, which could result in a possible uncontained failure of the HPCR spool/shaft and damage to the airplane. DATES: This AD becomes effective August 5, 2009. ADDRESSES: The Docket Operations office is located at Docket Management Facility, U.S. Department of Transportation, 1200 New Jersey Avenue, SE., West Building Ground Floor, Room W12–140, Washington, DC 20590–0001.

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 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Safety. Adoption of the Amendment Costs of Compliance We estimate that this AD will affect one engine installed on an airplane of U.S. registry. We also estimate that the actions would require no work-hours per engine. No parts are required. Based on these figures, we estimate there is no cost of this AD to U.S. operators. Accordingly, under the authority delegated to me by the Administrator, the Federal Aviation Administration amends 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES ■ 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. 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 PO 00000 Frm 00006 Fmt 4700 Sfmt 4700 § 39.13 [Amended] 2.

Temporary final rule. AGENCY: ACTION: The Coast Guard is suspending several special local regulations and establishing temporary SUMMARY: VerDate Nov<24>2008 15:16 Jun 30, 2009 Jkt 217001 safety zones in various communities along the central and northern coastline of Massachusetts. These safety zones will last for the limited duration of the fireworks. The zones are necessary to protect spectators, participants, and vessels from the hazards associated with fireworks displays. DATES: This rule is effective from June 27, 2009 through September 5, 2009.

If you have questions on viewing the docket, call Renee V. Wright, Program Manager, Docket Operations, telephone 202–366–9826. SUPPLEMENTARY INFORMATION: Regulatory Information The Coast Guard is issuing this temporary final rule without prior notice and opportunity to comment pursuant to authority under section 4(a) of the Administrative Procedure Act (APA) (5 U.S.C. 553(b)). This provision authorizes an agency to issue a rule without prior notice and opportunity to comment when the agency for good cause finds that those procedures are ‘‘impracticable, unnecessary, or contrary to the public interest.’’ Under 5 U.S.C. 553(b)(B), the Coast Guard finds that good cause exists for not publishing a notice of proposed rulemaking (NPRM) with respect to this rule because the Coast Guard was not notified of these events with adequate time to publish a NPRM, for fireworks displays that scheduled to occur on various dates between June 27, 2009 and September 05, 2009. Any delay encountered in the regulation’s effective date would be contrary to the public interest, since the safety zones are needed to prevent PO 00000 Frm 00007 Fmt 4700 Sfmt 4700 31351 traffic from transiting a portion of the coastal waters of Massachusetts during the fireworks displays thus ensuring that the maritime public is protected from any potential harm associated with such an event. For the same reason above, under 5 U.S.C. 553(d)(3), the Coast Guard finds that good cause exists for making this rule effective less than 30 days after publication in the Federal Register. Background and Purpose Various Massachusetts coastal cities are having fireworks displays on or near navigable waterways this summer. In order to maintain continuity between the regulations for fireworks events established in 33 CFR 100.114 and the rain dates requested for the same events this year, this temporary rule suspends several special local regulations entries in 33 CFR PART 100.114 FIREWORKS DISPLAY TABLE. It also establishes temporary safety zones surrounding the events as described in the List of Subjects. The proposed zones will protect the maritime public from the dangers inherent in waterborne fireworks displays. The Captain of the Port does not anticipate any negative impact on vessel traffic due to implementation of these temporary safety zones. Public notifications will be made prior to the effective period of each proposed zone via Broadcast and Local Notice to Mariners. Discussion of Rule The Coast Guard is establishing temporary safety zones in various coastal waterways throughout central and northern Massachusetts. The safety zones will be in effect for the times listed in the List of Subjects. Marine traffic will only be restricted from a portion of the waterway as stated in the List of Subjects to protect the safety of the maritime public. Due to the limited time frame of the fireworks display, the Captain of the Port anticipates minimal negative impact on vessel traffic due to this event. Public notifications will be made prior to the effective period via local and broadcast notice to mariners. Regulatory Analyses We developed this rule after considering numerous statutes and executive orders related to rulemaking. Below we summarize our analyses based on 13 of these statutes or executive orders.

Airworthiness Directives; General Electric Company (GE) CF6-
80C2B5F Turbofan Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for GE 
CF6-80C2B5F turbofan engines. This AD requires removing certain part 
number (P/N) high-pressure compressor rotor (HPCR) stages 11-14 spool/
shafts before they exceed a new, reduced life limit. This AD results 
from an internal GE audit that compared the life limited parts 
certification documentation to the airworthiness limitations section 
(ALS) of the instructions for continuing airworthiness (ICA). We are 
issuing this AD to prevent HPCR stages 11-14 spool/shaft fatigue cracks 
caused by exceeding the life limit, which could result in a possible 
uncontained failure of the HPCR spool/shaft and damage to the airplane.

DATES: This AD becomes effective August 5, 2009.

ADDRESSES: The Docket Operations office is located at Docket Management 
Facility, U.S. Department of Transportation, 1200 New Jersey Avenue, 
SE., West Building Ground Floor, Room W12-140, Washington, DC 20590-
0001.

FOR FURTHER INFORMATION CONTACT: Robert Green, Aerospace Engineer, 
Engine Certification Office, FAA, Engine & Propeller Directorate, 12

robert.green@faa.gov; telephone (781) 238-7754; fax (781) 238-7199.

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39 
with a proposed AD. The proposed AD applies to GE CF6-80C2B5F turbofan 
engines. We published the proposed AD in the Federal Register on 
February 20, 2009 (74 FR 7831). That action proposed to require 
removing certain P/N HPCR stages 11-14 spool/shafts before they exceed 
a new, reduced life limit.

Examining the AD Docket

    You may examine the AD docket on the Internet at https://www.regulations.gov; or in person at the Docket Operations office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains this AD, the regulatory evaluation, 
any comments received, and other information. The street address for 
the Docket Operations office (telephone (800) 647-5527) is provided in 
the ADDRESSES section. Comments will be available in the AD docket 
shortly after receipt.

Comments

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

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

    We estimate that this AD will affect one engine installed on an 
airplane of U.S. registry. We also estimate that the actions would 
require no work-hours per engine. No parts are required. Based on these 
figures, we estimate there is no cost of this AD to U.S. operators.

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 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.
