ACTION: Final rule. AGENCY: 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: The digital engine indicating system (DEI– NT) and associated control unit must get their latest software update. It has been found out in operation, that some combinations of system states while pressing switches can cause electrical damages to the system. A new software update is mandated to correct this deficiency and to incorporate additional safety functions to the system. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective October 26, 2007. On October 26, 2007, the Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD. ADDRESSES: You may examine the AD docket on the Internet at https:// dms.dot.gov or in person at Document Management Facility, U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue, SE., 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 E:\FR\FM\21SER1.SGM 21SER1 53924 Federal Register / Vol. 72, No. 183 / Friday, September 21, 2007 / Rules and Regulations NPRM was published in the Federal Register on June 28, 2007 (72 FR 35371). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: The digital engine ind icating system (DEI– NT) and associated control unit must get their latest software update. It has been found out in operation, that some combinations of system states while pressing switches can cause electrical damages to the system. A new software update is mandated to correct this deficiency and to incorporate additional safety functions to the system. As a result, the Flight and Maintenance Manuals need to be revised, specifically regarding the stall warning. You may obtain further information by examining the MCAI in the AD docket. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public. Conclusion We reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed. Differences Between This AD and the MCAI or Service Information We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information. We might also have required different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a NOTE within the AD. Costs of Compliance ebenthall on PROD1PC69 with RULES We estimate that this AD will affect 1 product of U.S. registry. We also estimate that it will take about 1 workhour per product to comply with basic requirements of this AD. The average labor rate is $80 per work-hour. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $80 or $80 per product. 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 VerDate Aug<31>2005 15:32 Sep 20, 2007 Jkt 211001 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 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://dms.dot.gov; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM, the regulatory evaluation, any comments received, and other information. The street address for the Docket Office (telephone (800) 647– 5527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.

ACTION: Final rule. AGENCY: SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from Mandatory Continuing Airworthiness Information (MCAI) provided by the aviation authority of France to identify and correct an unsafe condition on SICMA Aero Seat 50XXX Passenger Seats. The MCAI states the following: A release of smoke was experienced in the passenger compartment during flight after an overheating of a reading lights power box of a PN 5039201–4T SICMA seat. An analysis put into evidence that this overheating was caused by a short-circuit produced by the rupture of an electrical power supply component (PN 78147–B). It has been noticed that this power supply is not in compliance with DO 160 environmental standard. The short-circuiting could result in arcing and consequent smoke or fire. We are proposing this AD to prevent a short-circuit in the power box, which could result in smoke or fire in the airplane cabin. DATES: This AD becomes effective October 26, 2007.

We gave the public the opportunity to participate in developing this AD. We considered the comments received. Request To Revise the Costs of Compliance SICMA Aero Seat requests us to change the Costs of Compliance section of the AD to accurately depict the extent of the issue. SICMA has verified the number of affected power boxes installed in seats and the number already retrofitted. SICMA states that only 731 seats don’t comply with the AD and we should change the Costs of Compliance to reflect the new numbers. We agree. We changed the Costs to Comply to reflect the reduced number of affected seats. Conclusion We reviewed the available data, including the comment[s] received, and determined that air safety and the public interest require adopting the AD with the changes described previously. We determined that these changes will not increase the economic burden on any operator or increase the scope of the AD. Costs of Compliance We estimate that this AD will affect about 731 seats installed on airplanes of E:\FR\FM\21SER1.SGM 21SER1

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:

    The digital engine indicating system (DEI-NT) and associated 
control unit must get their latest software update. It has been 
found out in operation, that some combinations of system states 
while pressing switches can cause electrical damages to the system. 
A new software update is mandated to correct this deficiency and to 
incorporate additional safety functions to the system.

    We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective October 26, 2007.
    On October 26, 2007, the Director of the Federal Register approved 
the incorporation by reference of certain publications listed in this 
AD.

ADDRESSES: You may examine the AD docket on the Internet at https://

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

[[Page 53924]]

NPRM was published in the Federal Register on June 28, 2007 (72 FR 
35371). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    The digital engine ind icating system (DEI-NT) and associated 
control unit must get their latest software update. It has been 
found out in operation, that some combinations of system states 
while pressing switches can cause electrical damages to the system. 
A new software update is mandated to correct this deficiency and to 
incorporate additional safety functions to the system.

    As a result, the Flight and Maintenance Manuals need to be 
revised, specifically regarding the stall warning.

    You may obtain further information by examining the MCAI in the AD 
docket.

Comments

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

Conclusion

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

Differences Between This AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might also have required different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
highlighted in a NOTE within the AD.

Costs of Compliance

    We estimate that this AD will affect 1 product of U.S. registry. We 
also estimate that it will take about 1 work-hour per product to comply 
with basic requirements of this AD. The average labor rate is $80 per 
work-hour.
    Based on these figures, we estimate the cost of this AD to the U.S. 
operators to be $80 or $80 per product.

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 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://
dms.dot.gov; or in person at the Docket Management Facility between 9 
a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD

    (c) This AD applies to DG-1000T gliders, all serial numbers, 
certificated in any category.

Subject

    (d) Air Transport Association of America (ATA) Code 77: Engine 
Indicating.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:

    The digital engine indicating system (DEI-NT) and associated 
control unit must get their latest software update. It has been 
found out in operation, that some combinations of system states 
while pressing switches can cause electrical damages to the system. 
A new software update is mandated to correct this deficiency and to 
incorporate additional safety functions to the system.
    As a result, the Flight and Maintenance Manuals need to be 
revised, specifically regarding the stall warning.

Actions and Compliance

    (f) Within the next 60 days after October 26, 2007 (the 
effective day of this AD), unless already done, do the following 
actions:
    (1) Replace the Digital Indicating System (DEI-NT) unit with an 
updated unit that incorporates software version V1.5, and replace 
the control unit with an updated unit that incorporates software 
version V1.9 following DG-Flugzeugbau GmbH Technical Note No. 1000/
09, EASA approved December 12, 2006.
    (2) Insert the new Flight Manual pages 0.1, 0.5, 7.14, and 7.15 
and the new Maintenance Manual pages 0.1, 0.3, 0.6, 0.10, 1.22, and 
1.23, issued October 2006 marked with TN1000/09, and add Diagram 15a 
into your maintenance program (maintenance manual) following DG-
Flugzeugbau GmbH Technical Note No. 1000/09, EASA approved December 
12, 2006.
    (3) Prior to further flight after the action required by 
paragraph (f)(1) of this AD, do not install a DEI-NT or control unit 
in any DG-1000T airplane, unless it incorporates the software 
versions required in this AD.

    Note 1: The referenced DG-Flugzeugbau GmbH Technical Note No. 
1000/09, EASA approved December 12, 2006, also includes instructions 
for replacement of the fuel cock, which is not required by this AD.


    Note 2: As specified in the flight manual, the glider can only 
be operated in the non-powered configuration without the DEI-NT 
installed. Engine operation is not possible.
