Comments will be available in the AD docket shortly after the Docket Management System receives them. Discussion The Departamento de Aviacao Civil (DAC), which is the airworthiness authority for Brazil, notified us that an unsafe condition may exist on certain EMBRAER Model EMB–145XR airplanes. The Model EMB–145XR airplane is not certified to takeoff with the flaps set to 22 degrees; under this condition, aural and visual warnings should be activated to warn the flightcrew. However, the DAC advises that these aural and visual warnings were not enabled during the manufacture of certain airplanes. This condition, if not corrected, could result in an overrun of the runway during takeoff. Relevant Service Information EMBRAER has issued Service Bulletin 145–27–0113, dated December 6, 2005. The service bulletin describes procedures for modifying the flap system interface wiring. The modification includes the following steps: • Installing and connecting diodes CR0231 and CR0232 to splices SP4159, SP4160, and SP4161. • Disconnecting electrical wires W101–4176–24, W101–4178–24, and W101–4786–24 from electrical connectors J0739 and J0741, and rerouting and connecting them to splices SP4160, SP4159, and SP4161, respectively. • Routing electrical wires W101– 5783–24, W101–5787–24, and W101– 5789–24 and connecting them to electrical connectors J0739 and J0741. The DAC mandated the service information and issued Brazilian airworthiness directive 2006–02–01, dated February 24, 2006, to ensure the continued airworthiness of these airplanes in Brazil. FAA’s Determination and Requirements of the Proposed AD This airplane model is manufactured in Brazil and is type certificated for operation in the United States under the provisions of section 21.29 of the PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 19139 Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Pursuant to this bilateral airworthiness agreement, the DAC has kept the FAA informed of the situation described above. We have examined the DAC’s findings, evaluated all pertinent information, and determined that we need to issue an AD for airplanes of this type design that are certificated for operation in the United States. Therefore, we are proposing this AD, which would require accomplishing the actions specified in the service information described previously. Costs of Compliance This proposed AD would affect about 97 airplanes of U.S. registry. The proposed actions would take about 5 work hours per airplane, at an average labor rate of $80 per work hour. Required parts would cost about $60 per airplane. Based on these figures, the estimated cost of the proposed AD for U.S. operators is $44,620, or $460 per airplane. 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; E:\FR\FM\13APP1.SGM 13APP1 19140 Federal Register / Vol. 71, No. 71 / Thursday, April 13, 2006 / Proposed Rules 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. See the ADDRESSES section for a location to examine the regulatory evaluation. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Safety.

Discussion

    The Departamento de Aviacao Civil (DAC), which is the airworthiness 
authority for Brazil, notified us that an unsafe condition may exist on 
certain EMBRAER Model EMB-145XR airplanes. The Model EMB-145XR airplane 
is not certified to takeoff with the flaps set to 22 degrees; under 
this condition, aural and visual warnings should be activated to warn 
the flightcrew. However, the DAC advises that these aural and visual 
warnings were not enabled during the manufacture of certain airplanes. 
This condition, if not corrected, could result in an overrun of the 
runway during takeoff.

Relevant Service Information

    EMBRAER has issued Service Bulletin 145-27-0113, dated December 6, 
2005. The service bulletin describes procedures for modifying the flap 
system interface wiring. The modification includes the following steps:
     Installing and connecting diodes CR0231 and CR0232 to 
splices SP4159, SP4160, and SP4161.
     Disconnecting electrical wires W101-4176-24, W101-4178-24, 
and W101-4786-24 from electrical connectors J0739 and J0741, and 
rerouting and connecting them to splices SP4160, SP4159, and SP4161, 
respectively.
     Routing electrical wires W101-5783-24, W101-5787-24, and 
W101-5789-24 and connecting them to electrical connectors J0739 and 
J0741.
    The DAC mandated the service information and issued Brazilian 
airworthiness directive 2006-02-01, dated February 24, 2006, to ensure 
the continued airworthiness of these airplanes in Brazil.

FAA's Determination and Requirements of the Proposed AD

    This airplane model is manufactured in Brazil and is 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. Pursuant to this 
bilateral airworthiness agreement, the DAC has kept the FAA informed of 
the situation described above. We have examined the DAC's findings, 
evaluated all pertinent information, and determined that we need to 
issue an AD for airplanes of this type design that are certificated for 
operation in the United States.
    Therefore, we are proposing this AD, which would require 
accomplishing the actions specified in the service information 
described previously.

Costs of Compliance

    This proposed AD would affect about 97 airplanes of U.S. registry. 
The proposed actions would take about 5 work hours per airplane, at an 
average labor rate of $80 per work hour. Required parts would cost 
about $60 per airplane. Based on these figures, the estimated cost of 
the proposed AD for U.S. operators is $44,620, or $460 per airplane.

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;

[[Page 19140]]

    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. See the 
ADDRESSES section for a location to examine the regulatory evaluation.
