[FR Doc. 2011–11717 Filed 5–12–11; 8:45 am] BILLING CODE 8025–01–P SMALL BUSINESS ADMINISTRATION 13 CFR Part 121 RIN 3245–AG07 Small Business Size Standards: Professional, Scientific and Technical Services. U.S. Small Business Administration. ACTION: Proposed rule; notice of extension of comment period. AGENCY: On March 16, 2011, the U.S. Small Business Administration (SBA or Agency) proposed to increase small business size standards for 35 industries and one sub-industry in North American Industry Classification System (NAICS) Sector 54, Professional, Scientific and Technical Services and one industry in NAICS Sector 81, Other Services. SBA provided a 60-day comment period ending on May 16, 2011. In this notice, SBA is extending the comment period an additional 30 days to June 15, 2011. DATES: The comment period for the proposed rule published on March 16, 2011, at 76 FR 14323, is extended through June 15, 2011. ADDRESSES: You may submit comments, identified by RIN 3245–AG07 by one of the following methods: (1) Federal eRulemaking Portal: https://www.regulations.gov. Follow the instructions for submitting comments; or (2) Mail/Hand Delivery/Courier: Khem R. Sharma, PhD, Chief, Size Standards Division, 409 Third Street, SW., Mail Code 6530, Washington, DC 20416. FOR FURTHER INFORMATION CONTACT: The SBA’s Office of Size Standards at (202) 205–6618 or sizestandards@sba.gov. SUPPLEMENTARY INFORMATION: In the proposed rule (76 FR 14323), SBA sought public comment on whether the proposed increases to size standards are appropriate given the economic characteristics of industries. Based on its analysis of industry and Federal procurement data and the use of a common size standard, for some industries SBA proposed to increase the size standards by more than three times their current levels (e.g., Engineering, Architectural and Related Services), while for some other industries proposed increases are more modest WReier-Aviles on DSKGBLS3C1PROD with PROPOSALS SUMMARY: VerDate Mar<15>2010 15:16 May 12, 2011 Jkt 223001 (e.g., Computer System Designs and Related Services). SBA also sought public feedback on a number of policy issues regarding its size standards methodology, such as whether SBA’s proposal to apply eight fixed size standards levels is appropriate to simplify size standards and whether SBA should adopt a common size standards for related industries although the analysis might support a different size standard for each industry. As of May 9, 2011, SBA has received over 210 comments to the proposed rule which are posted on https:// www.regulations.gov. Some comments support SBA’s proposed increases, some feel that proposed increases are too large, and others believe that proposed increases are too small. Given the impact the proposed changes might have on affected businesses and the lack of consensus in the comments received to date, SBA believes that the Agency and the affected industries will benefit from more public input before it finalizes any changes. Therefore, SBA is extending the comment period to June 15, 2011. This will also give more time to affected businesses and interested parties to review the proposed changes and prepare accurate, constructive and convincing comments to the proposed rule.

Comments will be available in the AD docket shortly after receipt. Discussion The Direction Generale de l’Aviation Civile France (DGAC), which is the aviation authority for France, has issued French AD No. F–2005–175, dated October 26, 2005, on behalf of the European Aviation Safety Agency (EASA), the Airworthiness Authority of the State of Design for the affected helicopters, to correct an unsafe condition for the Eurocopter France Model EC 120B helicopters. WReier-Aviles on DSKGBLS3C1PROD with PROPOSALS Related Service Information Eurocopter has issued Alert Service Bulletin No. 67A011, Revision 1, dated October 7, 2005 (ASB), which specifies a modification to preclude the risk that the pilot cyclic control stick will jam. The modification consists of replacing the existing single-piece thrust washer, part number (P/N) C671A1006201, with two thrust washers, P/N C671A1018201 and P/N C671A1019201. The DGAC classified this alert service bulletin as mandatory and issued AD No. F–2005– 175, dated October 26, 2005, to ensure the continued airworthiness of these helicopters. FAA’s Evaluation and Unsafe Condition Determination This product has been approved by the aviation authority of France and is approved for operation in the United States. Pursuant to our bilateral agreement with France, the DGAC, on behalf of the EASA, their technical representative, has notified us of the unsafe condition described in the DGAC AD. We are proposing this AD because we evaluated all information provided VerDate Mar<15>2010 15:16 May 12, 2011 Jkt 223001 by the DGAC and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. This proposed AD would require replacing a single-piece thrust washer, P/N C671A1006201, with two thrust washers, P/N C671A1018201 and P/N C671A1019201, to prevent the jamming of the pilot cyclic control stick. Differences Between This Proposed AD and the DGAC AD The DGAC AD requires compliance with the ASB no later than December 31, 2005. Our proposed AD would require compliance within 30 days after the effective date of the AD. Costs of Compliance We estimate that this proposed AD would affect 114 helicopters of U.S. registry and the proposed actions would take approximately 3 work hours per helicopter to accomplish at an average labor rate of $85 per work hour. Required parts would cost approximately $50 per helicopter. Based on these figures, we estimate the total cost impact of the proposed AD on U.S. operators would be $34,770 for the entire fleet, or $305 per helicopter, to replace the single thrust washer with two thrust washers. Regulatory Findings We have determined that this proposed AD would not have federalism implications under Executive Order 13132. Additionally, 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. 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 an economic evaluation of the estimated costs to comply with this proposed AD. See the AD docket to examine the economic evaluation. 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 PO 00000 Frm 00035 Fmt 4702 Sfmt 4702 27953 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Safety. The Proposed Amendment Accordingly, pursuant to the authority delegated to me by the Administrator, the Federal Aviation Administration proposes to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

Discussion The EASA, which is the Technical Agent for the Member States of the European Community, has issued EASA Emergency AD (EAD) No. 2006–0362–E, dated November 30, 2006, to correct an unsafe condition for the specified Eurocopter model helicopters. The MCAI AD states: ‘‘This Emergency Airworthiness Directive is issued following some reports of deterioration and two reports of failure of Starflex star arm ends. These deteriorations generated high-amplitude vibrations in flight, compelling the pilot to carry out a precautionary landing, in each of these cases. The failure of the Starflex star arm end could make it impossible to control the helicopter. These deteriorations are due to the strong effect of temperature on the strength of the bush-to-Starflex star arm end attachment.

Discussion

    The Direction Generale de l'Aviation Civile France (DGAC), which is 
the aviation authority for France, has issued French AD No. F-2005-175, 
dated October 26, 2005, on behalf of the European Aviation Safety 
Agency (EASA), the Airworthiness Authority of the State of Design for 
the affected helicopters, to correct an unsafe condition for the 
Eurocopter France Model EC 120B helicopters.

Related Service Information

    Eurocopter has issued Alert Service Bulletin No. 67A011, Revision 
1, dated October 7, 2005 (ASB), which specifies a modification to 
preclude the risk that the pilot cyclic control stick will jam. The 
modification consists of replacing the existing single-piece thrust 
washer, part number (P/N) C671A1006201, with two thrust washers, P/N 
C671A1018201 and P/N C671A1019201. The DGAC classified this alert 
service bulletin as mandatory and issued AD No. F-2005-175, dated 
October 26, 2005, to ensure the continued airworthiness of these 
helicopters.

FAA's Evaluation and Unsafe Condition Determination

    This product has been approved by the aviation authority of France 
and is approved for operation in the United States. Pursuant to our 
bilateral agreement with France, the DGAC, on behalf of the EASA, their 
technical representative, has notified us of the unsafe condition 
described in the DGAC AD. We are proposing this AD because we evaluated 
all information provided by the DGAC and determined the unsafe 
condition exists and is likely to exist or develop on other products of 
the same type design. This proposed AD would require replacing a 
single-piece thrust washer, P/N C671A1006201, with two thrust washers, 
P/N C671A1018201 and P/N C671A1019201, to prevent the jamming of the 
pilot cyclic control stick.

Differences Between This Proposed AD and the DGAC AD

    The DGAC AD requires compliance with the ASB no later than December 
31, 2005. Our proposed AD would require compliance within 30 days after 
the effective date of the AD.

Costs of Compliance

    We estimate that this proposed AD would affect 114 helicopters of 
U.S. registry and the proposed actions would take approximately 3 work 
hours per helicopter to accomplish at an average labor rate of $85 per 
work hour. Required parts would cost approximately $50 per helicopter. 
Based on these figures, we estimate the total cost impact of the 
proposed AD on U.S. operators would be $34,770 for the entire fleet, or 
$305 per helicopter, to replace the single thrust washer with two 
thrust washers.

Regulatory Findings

    We have determined that this proposed AD would not have federalism 
implications under Executive Order 13132. Additionally, 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. 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 an economic evaluation of the estimated costs to comply 
with this proposed AD. See the AD docket to examine the economic 
evaluation.

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

The Proposed Amendment

    Accordingly, pursuant to the authority delegated to me by the 
Administrator, the Federal Aviation Administration proposes to amend 
part 39 of the Federal Aviation Regulations (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.


Sec.  39.13  [Amended]

    2. Section 39.13 is amended by adding a new airworthiness directive 
to read as follows:

Eurocopter France: Docket No. FAA-2011-0448; Directorate Identifier 
2007-SW-51-AD.

    Applicability: Model EC 120B helicopters, serial numbers up to 
and including 1385, with a thrust washer, part number (P/N) 
C671A1006201, installed on the pilot cyclic control stick friction 
device; and a pilot cyclic stick, P/N C671A1007101, P/N 
C671A1007102, or C671A1003102, installed, certificated in any 
category.
    Compliance: Required within 30 days, unless accomplished 
previously.
    To prevent jamming of a pilot cyclic control stick and 
subsequent loss of control of the helicopter, accomplish the 
following:
    (a) Remove the pilot cyclic control stick; replace the thrust 
washer, P/N C671A1006201, with two thrust washers, P/N C671A1018201 
and P/N C671A1019201; reinstall the pilot cyclic control stick; and 
perform a functional test of the cyclic control.
    (b) To request a different method of compliance or a different 
compliance time for this AD, follow the procedures in 14 CFR 39.19.
