Discussion The Departmento de Aviacao Civil (DAC), which is the airworthiness authority for Brazil, notified us that an unsafe condition may exist on certain EMBRAER Model EMB–135BJ airplanes. The DAC advises that certain airplanes were delivered with the fire blocking material missing and the seal improperly installed on the left- and right-hand partitions of the forward baggage compartment door. These E:\FR\FM\11APP1.SGM 11APP1 18248 Federal Register / Vol. 71, No. 69 / Tuesday, April 11, 2006 / Proposed Rules conditions, in the event of a fire in the baggage compartment, could result in smoke propagating into the main cabin. Relevant Service Information EMBRAER has issued Service Bulletin 145LEG–25–0060, dated November 18, 2005. The service bulletin describes procedures for doing a visual inspection for missing fire blocking material (an insulation blanket) on the partitions of the forward baggage compartment door, replacing the seal on both partitions with a new seal, and corrective action if necessary. The corrective action includes installing a new insulation blanket if fire blocking material is missing. Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. The DAC mandated the service information and issued Brazilian airworthiness directive 2006– 02–02, 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 The following table provides the estimated costs for U.S. operators to comply with this proposed AD. ESTIMATED COSTS Inspection ............................................................... Seal replacement ................................................... 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. hsrobinson on PROD1PC70 with PROPOSALS 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.

This proposed AD would require replacing the clamp bases for the fuel vent pipe with improved clamp bases. This proposed AD results from reports that the foil wrapping on existing plastic clamp bases has migrated out of position, which compromises the bonding of the fuel vent lines to the airplane structure. We are proposing this AD to ensure that the fuel vent lines are properly bonded to the airplane structure. Improper bonding could prevent electrical energy from a lightning strike from dissipating to the airplane structure, and create an ignition source, which could result in a fuel tank explosion.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain EMBRAER Model EMB-135BJ airplanes. This proposed AD would 
require inspecting for missing fire blocking material on the left- and 
right-hand partitions of the forward baggage compartment door; 
replacing the seal on both partitions; and performing corrective action 
if necessary. This proposed AD results from a report indicating that 
certain airplanes were delivered with the fire blocking material 
missing and the seal improperly installed on the partitions of the 
forward baggage compartment door. We are proposing this AD to detect 
and correct such discrepancies on the partitions of the forward baggage 
compartment door, which, in the event of a fire in the baggage 
compartment, could result in smoke propagating into the main cabin.

Discussion

    The Departmento de Aviacao Civil (DAC), which is the airworthiness 
authority for Brazil, notified us that an unsafe condition may exist on 
certain EMBRAER Model EMB-135BJ airplanes. The DAC advises that certain 
airplanes were delivered with the fire blocking material missing and 
the seal improperly installed on the left- and right-hand partitions of 
the forward baggage compartment door. These

[[Page 18248]]

conditions, in the event of a fire in the baggage compartment, could 
result in smoke propagating into the main cabin.

Relevant Service Information

    EMBRAER has issued Service Bulletin 145LEG-25-0060, dated November 
18, 2005. The service bulletin describes procedures for doing a visual 
inspection for missing fire blocking material (an insulation blanket) 
on the partitions of the forward baggage compartment door, replacing 
the seal on both partitions with a new seal, and corrective action if 
necessary. The corrective action includes installing a new insulation 
blanket if fire blocking material is missing. Accomplishing the actions 
specified in the service information is intended to adequately address 
the unsafe condition. The DAC mandated the service information and 
issued Brazilian airworthiness directive 2006-02-02, 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

    The following table provides the estimated costs for U.S. operators 
to comply with this proposed AD.

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;
    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.
