The intent of the amended test procedure was to require manufacturers to test for standby mode and off mode power at this time only if they intended to publicize such information, and for the above-stated reasons regarding the volume of and limited time available for testing, DOE agrees that requiring all basic models to be retested before April 18, 2011, would place an undue burden upon the petitioners. Likewise, DOE does not believe that it would be appropriate to prevent the dissemination of representations regarding auxiliary electrical energy consumption of residential furnaces and boilers, because consumers may find such information beneficial. Furthermore, DOE agrees that a 180-day extension would not be expected to harm consumers or undermine the purpose of the final rule. For these reasons, and given that the petitioners fulfilled their obligations under 42 U.S.C. 6293(c)(3), DOE hereby issues this Decision and Order which grants the 27 petitioners above an extension of 180 days for compliance with the amended provisions of the furnaces and boilers test procedure final rule that was published in the Federal Register on October 20, 2010. Accordingly, the petitioners must meet a new compliance date of October 15, 2011. With respect to Rheem’s request that DOE extend the compliance date to the end of the calendar year 2011, DOE reiterates that the maximum extension allowed by the statute is 180 days. As such, DOE denies Rheem’s request. DOE notes that this extension does not release petitioners from the certification requirements set forth in 10 CFR 430.62. Issued in Washington, DC, on March 24, 2011. Kathleen Hogan, Deputy Assistant Secretary for Energy Efficiency, Office of Technology Development, Energy Efficiency and Renewable Energy.

ACTION: Final rule. AGENCY: 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: SUMMARY: Service experience has shown that a case of FADEC channel B manifold air pressure (MAP) sensor hose permeability is not always recognized as fault by the FADEC. The MAP value measured by the sensor may be lower than the actual pressure value in the engine manifold, and limits the amount of fuel injected into the combustion chamber and thus the available power of the engine. A change in FADEC software version 2.91 will change the logic in failure detection and in switching to channel B (no automatic switch to channel B if MAP difference between channel A and B is detected and lower MAP is at channel B). In addition, previous software versions allow—under certain conditions and on DA 42 aircraft only—the initiation of a FADEC self test during flight that causes an engine in-flight shutdown. We are issuing this AD to prevent engine in-flight shutdown or power loss, possibly resulting in reduced control of the airplane. DATES: This AD becomes effective May 5, 2011. ADDRESSES: The Docket Operations office is located at Docket Management Facility, U.S. Department of Transportation, 1200 New Jersey Avenue, SE., West Building Ground Floor, Room W12–140, Washington, DC 20590–0001.

PO 00000 Frm 00003 Fmt 4700 Sfmt 4700 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 23, 2010 (75 FR 71371). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: Service experience has shown that a case of FADEC channel B manifold air pressure (MAP) sensor hose permeability is not always recognized as fault by the FADEC. The MAP value measured by the sensor may be lower than the actual pressure value in the engine manifold, and limits the amount of fuel injected into the combustion chamber and thus the available power of the engine.

In addition, previous software versions allow—under certain conditions and on DA 42 aircraft only—the initiation of a FADEC self test during flight that causes an engine in-flight shutdown. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM. We updated the revision levels to the two referenced Thielert Operation & Maintenance Manuals, and corrected a manual number reference error in paragraph (e)(2) of this AD. Conclusion We reviewed the available data 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 Based on the service information, we estimate that this AD will affect about 112 engines installed on airplanes of U.S. registry. We also estimate that it will take about 0.5 work-hour per engine to comply with this AD. The average labor rate is $85 per work-hour. There are no required parts cost. Based on these figures, we estimate the cost of the AD on U.S. operators to be $4,760. 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 E:\FR\FM\31MRR1.SGM 31MRR1 17758 Federal Register / Vol. 76, No. 62 / Thursday, March 31, 2011 / Rules and Regulations 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 the FAA amends 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

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:

    Service experience has shown that a case of FADEC channel B 
manifold air pressure (MAP) sensor hose permeability is not always 
recognized as fault by the FADEC. The MAP value measured by the 
sensor may be lower than the actual pressure value in the engine 
manifold, and limits the amount of fuel injected into the combustion 
chamber and thus the available power of the engine. A change in 
FADEC software version 2.91 will change the logic in failure 
detection and in switching to channel B (no automatic switch to 
channel B if MAP difference between channel A and B is detected and 
lower MAP is at channel B).
    In addition, previous software versions allow--under certain 
conditions and on DA 42 aircraft only--the initiation of a FADEC 
self test during flight that causes an engine in-flight shutdown.

We are issuing this AD to prevent engine in-flight shutdown or power 
loss, possibly resulting in reduced control of the airplane.

DATES: This AD becomes effective May 5, 2011.

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 23, 2010 
(75 FR 71371). That NPRM proposed to correct an unsafe condition for 
the specified products. The MCAI states:

    Service experience has shown that a case of FADEC channel B 
manifold air pressure (MAP) sensor hose permeability is not always 
recognized as fault by the FADEC. The MAP value measured by the 
sensor may be lower than the actual pressure value in the engine 
manifold, and limits the amount of fuel injected into the combustion 
chamber and thus the available power of the engine. A change in 
FADEC software version 2.91 will change the logic in failure 
detection and in switching to channel B (no automatic switch to 
channel B if MAP difference between channel A and B is detected and 
lower MAP is at channel B).
    In addition, previous software versions allow--under certain 
conditions and on DA 42 aircraft only--the initiation of a FADEC 
self test during flight that causes an engine in-flight shutdown.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM.
    We updated the revision levels to the two referenced Thielert 
Operation & Maintenance Manuals, and corrected a manual number 
reference error in paragraph (e)(2) of this AD.

Conclusion

    We reviewed the available data 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

    Based on the service information, we estimate that this AD will 
affect about 112 engines installed on airplanes of U.S. registry. We 
also estimate that it will take about 0.5 work-hour per engine to 
comply with this AD. The average labor rate is $85 per work-hour. There 
are no required parts cost. Based on these figures, we estimate the 
cost of the AD on U.S. operators to be $4,760.

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

[[Page 17758]]

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 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 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 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 (phone: (800) 647-5527) is provided in the 
ADDRESSES section. Comments will be available in the AD docket shortly 
after receipt.
