Download as PDF Federal Register / Vol. 76, No. 36 / Wednesday, February 23, 2011 / Rules and Regulations The two comments that were received after the deadline have also been considered by SBA. Both submitters suggested that the regulation be amended to include contracts for the sale of biomass products to increase the number of contracts for which small businesses could obtain bonding. SBA agrees and has modified the definition of ‘‘Contract’’ in this final rule to clarify that this change applies to contracts for the sale of timber as well as other forest products, including biomass. Compliance With Executive Orders 12866, 12988, and 13132, the Paperwork Reduction Act (44 U.S.C. Ch. 35) and the Regulatory Flexibility Act (5 U.S.C. 601–612) Executive Order 12866 The Office of Management and Budget (OMB) has determined that this rule does not constitute a significant regulatory action under Executive Order 12866. This rule is also not a major rule under the Congressional Review Act. Executive Order 12988 This action meets applicable standards set forth in Sections 3(a) and 3(b)(2) of Executive Order 12988, Civil Justice Reform, to minimize litigation, eliminate ambiguity, and reduce burden. The action does not have retroactive or preemptive effect. Executive Order 13132 For purposes of Executive Order 13132, SBA has determined that this final rule will not have substantial, direct effects 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. Therefore, for the purpose of Executive Order 13132, Federalism, SBA has determined that this final rule has no federalism implications warranting preparation of a federalism assessment. WReier-Aviles on DSKDVH8Z91PROD with RULES Paperwork Reduction Act, 44 U.S.C., Ch. 35 SBA has determined that this final rule does not impose additional reporting or recordkeeping requirements under the Paperwork Reduction Act, 44 U.S.C., Chapter 35. Regulatory Flexibility Act, 5 U.S.C. 601– 612 The Regulatory Flexibility Act (RFA), 5 U.S.C. 601, requires administrative agencies to consider the effect of their actions on small entities, small nonprofit enterprises, and small local governments. Pursuant to the RFA, when an agency issues a rulemaking, VerDate Mar<15>2010 14:51 Feb 22, 2011 Jkt 223001 the agency must prepare a regulatory flexibility analysis which describes the impact of the rule on small entities. However, section 605 of the RFA allows an agency to certify a rule, in lieu of preparing an analysis, if the rulemaking is not expected to have a significant economic impact on a substantial number of small entities. Within the meaning of RFA, SBA certifies that this rule will not have a significant economic impact on a substantial number of small entities. There are seventeen Sureties that participate in the SBA program, and no part of this final rule would impose any significant additional cost or burden on them.

ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: SUMMARY: Service experience has shown that fracture of the timing chain has occurred due to chain wear. This condition, if not corrected, could lead to in-flight cases of engine shutdown. We are issuing this AD to prevent engine in-flight shutdown leading to loss of control of the airplane by requiring life limits for the timing chain. DATES: This AD becomes effective March 30, 2011. 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.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on October 28, 2010 (75 FR 66342). That NPRM proposed to correct an unsafe condition for the specified products.

This condition, if not corrected, could lead to in-flight cases of engine shutdown. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM. Conclusion We reviewed the relevant data and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance Based on the service information, we estimate that this AD will affect about 112 engines installed on airplanes of U.S. registry. We also estimate that it will take about 8 work-hours per product to comply with this AD. The average labor rate is $85 per work-hour. Required parts will cost about $162 per engine. Based on these figures, we estimate the cost of the AD on U.S. operators to be $94,304. 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. WReier-Aviles on DSKDVH8Z91PROD with RULES Regulatory Findings We 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 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 VerDate Mar<15>2010 14:51 Feb 22, 2011 Jkt 223001 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. 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.

SUPPLEMENTARY INFORMATION: History On October 22, 2010, the FAA published in the Federal Register a notice of proposed rulemaking to amend Class E surface airspace and airspace 700 feet above the surface, and remove Class E airspace designated as an extension to Class D airspace at Easton, MD (75 FR 65250) Docket No. FAA– 2010–0936. Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. No comments were received. Class E airspace designations are published in paragraph 6005 of FAA Order 7400.9U dated August 18, 2010, and effective September 15, 2010, which is incorporated by reference in 14 CFR 71.1. The Class E airspace designations listed in this document will be published subsequently in the Order. DEPARTMENT OF TRANSPORTATION The Rule Federal Aviation Administration This amendment to Title 14, Code of Federal Regulations (14 CFR) part 71 amends the Class E surface airspace and Class E airspace extending upward from 700 feet above the surface to accommodate new SIAPs developed for Easton Airport/Newnam Field, Easton, MD, as the Easton NDB has been decommissioned. This eliminates the need for Class E airspace designated as an extension to Class D surface area, and, therefore, will be removed for the continued safety and management of IFR operations at the airport. The FAA has determined that this regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current, is non-controversial and unlikely to result in adverse or negative comments. It, therefore, (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) does not warrant preparation of a Regulatory Evaluation as the anticipated impact is so minimal.

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above. This AD results from mandatory continuing 
airworthiness information (MCAI) issued by an aviation authority of 
another country to identify and correct an unsafe condition on an 
aviation product. The MCAI describes the unsafe condition as:

    Service experience has shown that fracture of the timing chain 
has occurred due to chain wear. This condition, if not corrected, 
could lead to in-flight cases of engine shutdown.

We are issuing this AD to prevent engine in-flight shutdown leading to 
loss of control of the airplane by requiring life limits for the timing 
chain.

DATES: This AD becomes effective March 30, 2011.

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-

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM was published in the Federal Register on October 28, 2010 (75 
FR 66342). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    Service experience has shown that fracture of the timing chain 
has occurred due to chain

[[Page 9964]]

wear. This condition, if not corrected, could lead to in-flight 
cases of engine shutdown.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting the AD as proposed.

Costs of Compliance

    Based on the service information, we estimate that this AD will 
affect about 112 engines installed on airplanes of U.S. registry. We 
also estimate that it will take about 8 work-hours per product to 
comply with this AD. The average labor rate is $85 per work-hour. 
Required parts will cost about $162 per engine. Based on these figures, 
we estimate the cost of the AD on U.S. operators to be $94,304.

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 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 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 regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.

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 (phone (800) 647-5527) is provided in the 
ADDRESSES section. Comments will be available in the AD docket shortly 
after receipt.

    (2) For engines with S/Ns not listed in Table 1 of this AD, 
replace the timing chain within 910 flight hours-since-new, or no 
later than 55 flight hours after the effective date of this AD, 
whichever occurs later.

Repetitive Replacements of Timing Chains for All TAE 125-02-99 and TAE 
125-02-114 Engines

    (3) Thereafter, for all TAE 125-02-99 and TAE 125-02-114 
engines, repetitively replace the timing chain within every 
additional 910 flight hours.
    (4) Guidance on replacing the timing chain can be found in 
Thielert Aircraft Engines GmbH Service Bulletin No. TM TAE 125-1010 
P1, Revision 2, dated May 26, 2010.

FAA AD Differences

    (f) This AD differs from the MCAI and/or service information, 
which require initial replacement of the timing chain for the 
engines listed in paragraph (e)(1) above within either the next 110 
flight hours or at the next maintenance, whichever occurs first, for 
those engines having accumulated between 500 and 600 flight hours 
time-since-new. The reason for the difference is to ensure that the 
compliance requirements for all engines in paragraph (e)(1) above 
are consistent.
