ACTION: Final rule. AGENCY: SUMMARY: We are superseding an existing 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 distortion of the rudder bars due to rudder control forces during aerobatic operation and nose wheel steering reaction forces. Rudder bar distortion could result in reduced control or loss of control. This AD requires actions that are intended to address the unsafe condition described in the MCAI. DATES: This AD becomes effective March 11, 2008. As of March 11, 2008, 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:// www.regulations.gov or in person at the Docket 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: published in 1987 and AD 99–01–04, Amendment 39–10971, published in 1999. That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states that rudder control forces during aerobatic operation and nose wheel steering reaction forces may cause rudder bar distortion. Rudder bar distortion could result in reduced control or loss of control. The MCAI requires you to replace the left and right rudder bars with reinforced rudder bars. 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 9 products of U.S. registry. We also estimate that it will take about 3 workhours per product to comply with basic requirements of this AD. The average labor rate is $80 per work-hour. Required parts will cost about $657 per product. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $8,073 or $897 per product. Discussion Authority for This Rulemaking 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 November 27, 2007 (72 FR 66089) and proposed to supersede AD 87–08–01, Amendment 39–5601, 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.

ACTION: Final rule; request for comments. rmajette on PROD1PC64 with RULES AGENCY: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain ATR Model ATR42–500 series airplanes. This AD requires removing metallized polyethylene terephtalate (MPET) insulation blankets installed on the left and the right sides of the airplane over frame 24 between stringers 5 and 14. This AD results from reports indicating that burnt spots were found on the MPET insulation blankets installed over frame 24. The actions specified by this AD are intended to ensure that MPET insulation blankets are removed over frame 24. Such MPET insulation blankets, if not removed, could propagate a small fire that is the result of an electrical arc and could lead to a much larger fire.

SUPPLEMENTARY INFORMATION: Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, notified us that an unsafe condition may exist on certain ATR Model ATR42–500 series airplanes. The EASA advises that there have been reports of two in-service aircraft where burnt spots were found on the insulation blankets installed over frame 24. Investigations concluded that due to the presence of the bleed air duct, installation of the thermal-acoustical insulation blankets having a metallized polyethylene terephtalate (MPET) made the covering (also known as Mylar TM) at this location unsafe. Such MPET insulation blankets, if not removed, could propagate a small fire that is the result of an electrical arc and could lead to a much larger fire. This action is intended to address the identified unsafe condition. Relevant Service Information ATR has issued Service Bulletin ATR42–25–0155, dated April 10, 2007. The service bulletin describes procedures for removing the MPET insulation blankets installed on the left PO 00000 Frm 00018 Fmt 4700 Sfmt 4700 and the right sides of the airplane over frame 24 between stringers 5 and 14. Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. The EASA mandated the service information and issued emergency airworthiness directive 2007–0106–E, dated April 18, 2007, to ensure the continued airworthiness of these airplanes in the European Union. FAA’s Determination and Requirements of This AD These airplanes are manufactured in France and are type certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. As described in FAA Order 8100.14A, ‘‘Interim Procedures for Working with the European Community on Airworthiness Certification and Continued Airworthiness,’’ dated August 12, 2005, the EASA has kept the FAA informed of the situation described above. We have examined the EASA’s findings, evaluated all pertinent information, and determined that we need to issue an AD for products of this type design that are certificated for operation in the United States. Therefore, we are issuing this AD to ensure that MPET insulation blankets are removed over frame 24. Such MPET insulation blankets, if not removed, could propagate a small fire that is the result of an electrical arc and could lead to a much larger fire. This AD requires accomplishing the actions specified in the service information described previously. Costs of Compliance None of the airplanes affected by this action are on the U.S. Register. All airplanes affected by this AD are currently operated by non-U.S. operators under foreign registry; therefore, they are not directly affected by this AD action. However, we consider this AD necessary to ensure that the unsafe condition is addressed if any affected airplane is imported and placed on the U.S. Register in the future. If an affected airplane is imported and placed on the U.S. Register in the future, the required action would take about 6 work hours per airplane, at an average labor rate of $80 per work hour. Based on these figures, the estimated cost of the AD would be $480 per airplane. FAA’s Determination of the Effective Date No airplane affected by this AD is currently on the U.S. Register.

R2160 Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are superseding an existing 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 distortion of the rudder bars due to rudder control forces 
during aerobatic operation and nose wheel steering reaction forces. 
Rudder bar distortion could result in reduced control or loss of 
control. This AD requires actions that are intended to address the 
unsafe condition described in the MCAI.

DATES: This AD becomes effective March 11, 2008.
    As of March 11, 2008, the Director of the Federal Register approved 
the incorporation by reference of certain publications listed in this 
AD.

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 November 27, 2007 
(72 FR 66089) and proposed to supersede AD 87-08-01, Amendment 39-5601, 
published in 1987 and AD 99-01-04, Amendment 39-10971, published in 
1999. That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states that rudder control forces during 
aerobatic operation and nose wheel steering reaction forces may cause 
rudder bar distortion. Rudder bar distortion could result in reduced 
control or loss of control.
    The MCAI requires you to replace the left and right rudder bars 
with reinforced rudder bars.

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 9 products of U.S. registry. 
We also estimate that it will take about 3 work-hours per product to 
comply with basic requirements of this AD. The average labor rate is 
$80 per work-hour. Required parts will cost about $657 per product.
    Based on these figures, we estimate the cost of this AD to the U.S. 
operators to be $8,073 or $897 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.

[[Page 6593]]

    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://
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 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.

Subject

    (d) Air Transport Association of America (ATA) Code 27: Flight 
Controls.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states that rudder control forces during aerobatic operation and 
nose wheel steering reaction forces may cause rudder bar distortion. 
Rudder bar distortion could result in reduced or loss of control. 
The MCAI requires you to replace the left and right rudder bars with 
reinforced rudder bars.
