ACTION: Final rule. The FAA is adopting a new airworthiness directive (AD) for Hamilton Sundstrand Power Systems T–62T–46C12 auxiliary power units (APUs). This AD requires upgrading the software in the APU full-authority digital controller (FADEC) from software version 02.01.000 to version 03.00.000. This AD results from two reports of APU compartment explosions due to over-fueling of the APU at low revolutions-per-minute during the start sequence. We are issuing this AD to prevent over-fueling of the APU during the start sequence, which could lead to fuel explosions, injury, and damage to the APU and the airplane. DATES: This AD becomes effective November 20, 2009. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulations as of November 20, 2009. ADDRESSES: You can get the service information identified in this AD from Hamilton Sundstrand Technical Publications, One Hamilton Road, Mail CPrice-Sewell on DSKDVH8Z91PROD with RULES SUMMARY: VerDate Nov<24>2008 15:49 Oct 15, 2009 Jkt 220001 Stop: 1A–3–Z63, Windsor Locks, CT 06096–1010; telephone (860) 654–3575.

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39 with a proposed AD. The proposed AD applies to Hamilton Sundstrand Power Systems T–62T–46C12 APUs. We published the proposed AD in the Federal Register on April 13, 2009 (74 FR 16811). That action proposed to require upgrading the software in the APU FADEC from software version 02.01.000 to version 03.00.000. Examining the AD Docket You may examine the AD docket on the Internet at http:// 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. One commenter states that we should reference Revision 2 of Hamilton Sundstrand Power Systems Service Bulletin (SB) No. 4503067–49–12 instead of referencing Revision 1 of that SB. Revision 1 had a technical error in it that prevented loading the software change. We agree. We changed the AD to reference Revision 2 of the SB. 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 with the change described previously. We have determined that this change will neither increase the PO 00000 Frm 00009 Fmt 4700 Sfmt 4700 53159 economic burden on any operator nor increase the scope of the AD. Costs of Compliance We estimate that this AD will affect 59 Hamilton Sundstrand Power Systems T–62T–46C12 APUs installed on airplanes of U.S. registry. We also estimate that it will take about three work-hours per APU to perform the actions, and that the average labor rate is $80 per work-hour. There is no required part cost. Based on these figures, we estimate the total cost of the AD to U.S. operators to be $14,160. 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.

ACTION: Final rule. SUMMARY: This action amends Class D and Class E airspace at Forbes Field Airport, Topeka, KS. Additional controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures (SIAPs) at Forbes Field Airport, Topeka, KS. This action also incorporates the Class E extensions to Class D airspace at Forbes Field Airport into the Class D surface area.

PO 00000 Frm 00010 Fmt 4700 Sfmt 4700 This action amends Title 14 Code of Federal Regulations (14 CFR) Part 71 by amending Class D and Class E airspace at Forbes Field Airport, Topeka, KS, for the safety and management of IFR operations at the airport. The Class E surface area designated as an extension to a Class D surface area will be added to the Class D airspace area. 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. Therefore, this regulation: (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.

Airworthiness Directives; Hamilton Sundstrand Power Systems T-
62T-46C12 Auxiliary Power Units

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
Hamilton Sundstrand Power Systems T-62T-46C12 auxiliary power units 
(APUs). This AD requires upgrading the software in the APU full-
authority digital controller (FADEC) from software version 02.01.000 to 
version 03.00.000. This AD results from two reports of APU compartment 
explosions due to over-fueling of the APU at low revolutions-per-minute 
during the start sequence. We are issuing this AD to prevent over-
fueling of the APU during the start sequence, which could lead to fuel 
explosions, injury, and damage to the APU and the airplane.

DATES: This AD becomes effective November 20, 2009. The Director of the 
Federal Register approved the incorporation by reference of certain 
publications listed in the regulations as of November 20, 2009.

ADDRESSES: You can get the service information identified in this AD 
from Hamilton Sundstrand Technical Publications, One Hamilton Road,

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39 
with a proposed AD. The proposed AD applies to Hamilton Sundstrand 
Power Systems T-62T-46C12 APUs. We published the proposed AD in the 
Federal Register on April 13, 2009 (74 FR 16811). That action proposed 
to require upgrading the software in the APU FADEC from software 
version 02.01.000 to version 03.00.000.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://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.
    One commenter states that we should reference Revision 2 of 
Hamilton Sundstrand Power Systems Service Bulletin (SB) No. 4503067-49-
12 instead of referencing Revision 1 of that SB. Revision 1 had a 
technical error in it that prevented loading the software change.
    We agree. We changed the AD to reference Revision 2 of the SB.

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 with the change described previously. 
We have determined that this change will neither increase the economic 
burden on any operator nor increase the scope of the AD.

Costs of Compliance

    We estimate that this AD will affect 59 Hamilton Sundstrand Power 
Systems T-62T-46C12 APUs installed on airplanes of U.S. registry. We 
also estimate that it will take about three work-hours per APU to 
perform the actions, and that the average labor rate is $80 per work-
hour. There is no required part cost. Based on these figures, we 
estimate the total cost of the AD to U.S. operators to be $14,160.

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.
