Airworthiness Directives; Empresa Brasileira de Aeronautica S.A.
(EMBRAER) Model EMB-135 Airplanes, and Model EMB-145, -145ER, -145MR, -
145LR, -145XR, -145MP, and -145EP Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding an existing airworthiness directive
(AD), which applies to certain EMBRAER Model EMB-135 airplanes and
Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP
airplanes. That AD currently requires replacing the metallic tubes
enclosing the vent and pilot valve wires in the left- and right-hand
wing fuel tanks with non-conductive hoses. This new AD adds airplanes
to the applicability of the existing AD. This AD results from fuel
system reviews conducted by the manufacturer. We are issuing this AD to
prevent an ignition source inside the fuel tank that could ignite fuel
vapor and cause a fuel tank explosion and loss of the airplane.
DATES: This AD becomes effective September 23, 2008.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of September 23,
2008.
On July 19, 2007 (72 FR 32780, June 14, 2007), the Director of the
Federal Register approved the incorporation by reference of certain
other documents.

SUPPLEMENTARY INFORMATION:
Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to include an AD that supersedes AD 2007-12-17, amendment
39-15095 (72 FR 32780, June 14, 2007). The existing AD applies to
certain EMBRAER Model EMB-135 airplanes and Model EMB-145, -145ER, -
145MR, -145LR, -145XR, -145MP, and -145EP airplanes. That NPRM was
published in the Federal Register on June 20, 2008 (73 FR 35098). That
NPRM proposed to continue to require replacing the metallic tubes
enclosing the vent and pilot valve wires in the left- and right-hand
wing fuel tanks with non-conductive hoses. That NPRM also proposed to
add airplanes to the applicability of the existing AD.
Comments
We provided the public the opportunity to participate in the
development of this AD. No comments have been received on the NPRM or
on the determination of the cost to the public.
Conclusion
We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD as proposed.
Costs of Compliance
The following table provides the estimated costs for U.S. operators
to comply with this AD. The average labor rate is $80 per work hour.
Estimated Costs

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