How should the Council measure and assess the leverage of a nonbank financial firm? How should measures of leverage address liabilities, off-balance sheet exposures, and non-financial business lines? Should standards for leverage differ by types of financial activities or by industry? Should acceptable leverage standards recognize differences in regulation? Are there existing standards (e.g., the Basel III leverage ratio) for measuring leverage that could be used in assessing the leverage of nonbank financial companies? 9. How should the Council measure and assess the amount and types of liabilities, including the degree of reliance on short-term funding of a nonbank financial firm? a. What factors should the Council consider in developing thresholds for identifying excessive reliance on shortterm funding? b. How should funding concentrations be measured? c. Do some nonbank financial companies have funding sources that are contractually short-term but stable in practice (similar to ‘‘stable deposits’’ at banks)? d. Should the assessment link the maturity structure of the liabilities to the maturity structure and quality of the assets of nonbank financial companies? 10. How should the Council take into account the fact that a nonbank financial firm (or one or more of its subsidiaries or affiliates) is already subject to financial regulation in the Council’s decision to designate a firm? Are there particular aspects of prudential regulation that should be considered as particularly important (e.g., capital regulation, liquidity requirements, consolidated supervision)? Should the Council take into account whether the existing regulation of the company comports with relevant national or international standards? 11. Should the degree of public disclosures and transparency be a factor in the assessment? Should asset valuation methodologies (e.g., level 2 and level 3 assets) and risk management practices be factored into the assessment? 12. During the financial crisis, the U.S. Government instituted a variety of programs that served to strengthen the resiliency of the financial system. Nonbank financial companies participated in several of these programs. How should the Council consider the Government’s extension of financial assistance to nonbank financial companies in designating companies? VerDate Mar<15>2010 15:08 Oct 05, 2010 Jkt 223001 13. Please provide examples of best practices used by your organization or in your industry in evaluating and considering various types of risks that could be systemic in nature. a. How do you approach analyzing and quantifying interdependencies with other organizations? b. When and if important counterparties or linkages are identified, how do you evaluate and quantify the risks that a firm is exposed to? c. What other types of information would be effective in helping to identify and avoid excessive risk concentrations that could ultimately lead to systemic instability? 14. Should the Council define ‘‘material financial distress’’ or ‘‘financial stability’’? If so, what factors should the Council consider in developing those definitions? 15. What other risk-related considerations should the Council take into account when establishing a framework for designating nonbank financial companies? Dated: October 1, 2010.

We will also post a report summarizing each substantive verbal contact we receive concerning this proposed AD. Discussion In 2007, a Diamond DA42 airplane experienced a dual in-flight engine shutdown. Our review of the incident determined the root cause was an unsafe design feature that allowed momentary interruption of electrical power to both engine FADECs. The interruption caused the FADECs to reset, shutting down both engines with a consequent loss of engine power. Piper Model PA– 28–161 airplanes modified by STC No. SA03303AT have a similar unsafe design feature that can allow the FADEC to shut down or reset if the main battery is depleted and the electrical charging system malfunctions. This condition, if not corrected, could result in an uncommanded engine shutdown. This failure could lead to a loss of engine power. Relevant Service Information We have reviewed Thielert Aircraft Engines GmbH Service Bulletin TM TAE 651–0007, Revision 7, dated July 30, 2010. The service information describes procedures for installation of a FADEC backup battery. FAA’s Determination and Requirements of the Proposed AD We are proposing this AD because we evaluated all information and determined the unsafe condition described previously is likely to exist or develop on other products of the same type design. This proposed AD would require installation of a FADEC backup battery, replacement of the supplement pilot’s operating handbook and FAA approved airplane flight manual, and revision of the limitations section of the supplement airplane maintenance manual. Costs of Compliance We estimate that this proposed AD would affect zero airplanes in the U.S. registry. We estimate the following costs to do the proposed modification: Labor cost Parts cost Total cost per airplane 7 work-hours × $85 per hour = $595 .................................................................. $780 $1,375 ....................... 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 DSKGBLS3C1PROD with PROPOSALS 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.

Discussion

    In 2007, a Diamond DA42 airplane experienced a dual in-flight 
engine shutdown. Our review of the incident determined the root cause 
was an unsafe design feature that allowed momentary interruption of 
electrical power to both engine FADECs. The interruption caused the 
FADECs to reset, shutting down both engines with a consequent loss of 
engine power. Piper Model PA-28-161 airplanes modified by STC No. 
SA03303AT have a similar unsafe design feature that can allow the FADEC 
to shut down or reset if the main battery is depleted and the 
electrical charging system malfunctions.
    This condition, if not corrected, could result in an uncommanded 
engine shutdown. This failure could lead to a loss of engine power.

Relevant Service Information

    We have reviewed Thielert Aircraft Engines GmbH Service Bulletin TM 
TAE 651-0007, Revision 7, dated July 30, 2010.
    The service information describes procedures for installation of a 
FADEC backup battery.

FAA's Determination and Requirements of the Proposed AD

    We are proposing this AD because we evaluated all information and 
determined the unsafe condition described previously is likely to exist 
or develop on other products of the same type design. This proposed AD 
would require installation of a FADEC backup battery, replacement of 
the supplement pilot's operating handbook and FAA approved airplane 
flight manual, and revision of the limitations section of the 
supplement airplane maintenance manual.

Costs of Compliance

    We estimate that this proposed AD would affect zero airplanes in 
the U.S. registry.
    We estimate the following costs to do the proposed modification:

----------------------------------------------------------------------------------------------------------------
           Labor cost                Parts cost        Total cost per airplane      Total cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
7 work-hours x $85 per hour =               $780   $1,375........................  Not applicable.
 $595.
----------------------------------------------------------------------------------------------------------------

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. 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 proposed AD and placed it in the AD docket.

Examining the AD Docket

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