14 CFR Part 39
[Docket No. FAA-2004-19767; Directorate Identifier 2004-NM-139-AD;
Amendment 39-13900; AD 2004-25-12]
RIN 2120-AA64
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A.
(EMBRAER) Model EMB-135 and -145 Series Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all
EMBRAER Model EMB-135 and -145 series airplanes. This AD requires a
one-time inspection of each passenger service unit (PSU) to determine
the serial number of the printed circuit board (PCB) installed in each
PSU, replacement of the PCB if necessary, related investigative
actions, and other specified actions. This AD is prompted by reports
that PSUs on two airplanes emitted smoke. We are issuing this AD to
prevent failure of a PSU, which could result in smoke or fire in the
airplane's passenger cabin.
DATES: This AD becomes effective January 13, 2005.
The incorporation by reference of certain publications listed in
the AD is approved by the Director of the Federal Register as of
January 13, 2005.
ADDRESSES: For service information identified in this AD, contact
Empresa Brasileira de Aeronautica S.A. (EMBRAER), PO Box 343-CEP
12.225, Sao Jose dos Campos-SP, Brazil. You can examine this
information at the National Archives and Records Administration (NARA).

Examining the Docket
The AD docket contains the proposed AD, comments, and any final
disposition. You can examine the AD docket on the Internet at http://dms.dot.gov
, or in person at the Docket Management Facility office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The Docket Management Facility office (telephone (800) 647-
5227) is located on the plaza level of the Nassif Building at the DOT
street address stated in the ADDRESSES section.
SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR Part 39
with an AD for all EMBRAER Model EMB-135 and -145 series airplanes. The
proposed AD was published in the Federal Register on September 9, 2004
(69 FR 54596), to require a one-time inspection of each passenger
service unit (PSU) to determine the serial number of the printed
circuit board (PCB) installed in each PSU, replacement of the PCB if
necessary, related investigative actions, and other specified actions.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the single comment that has
been submitted on the proposed AD.
Request To Limit Applicability
The commenter requests that we limit the applicability to airplanes
having serial numbers (S/Ns) up to and including 828. The commenter
states that it has received information from the airplane manufacturer
that the PSUs on airplanes having S/N 829 and subsequent will be
inspected during production.
We partially agree with the commenter's request. We do not agree to
revise the applicability statement of paragraph (a) of this AD. We note
that paragraph (h) of this AD prohibits the installation of an affected
part with an affected S/N. This prohibition should apply to all
airplanes, including those with S/Ns 829 and subsequent, which will
have been inspected in production. Therefore, the applicability
statement of this AD continues to identify all EMBRAER Model EMB-135
and -145 series airplanes, so that paragraph (h) will prohibit
installing an affected part on all of these airplanes. However, we
agree that airplanes that have been inspected during production do not
need to be inspected as required by paragraph (f) of this AD.
Therefore, we have revised paragraph (f) of this AD to apply only to
airplanes having S/Ns 001 through 828 inclusive.
Conclusion
We have carefully reviewed the available data, including the
comment that has been submitted, and determined that air safety and the
public interest require adopting the AD with the change described
previously. We have determined that this change will neither increase
the economic burden on any operator nor increase the scope of the AD.
Costs of Compliance
This AD affects about 539 airplanes of U.S. registry. The required
actions take about 3 work hours per airplane, at an average labor rate
of $65 per work hour. Based on these figures, the estimated cost of the
AD for U.S. operators is $105,105, or $195 per airplane.
Authority for This Rulemaking
The FAA's authority to issue rules regarding aviation safety is
found in Title 49 of the United States Code. 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.
This rulemaking is promulgated under the authority described in
[[Page 71340]]
Subtitle VII, Part A, Subpart III, Section 44701, ``General
requirements.'' Under that section, the FAA is charged 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 AD.
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. See the ADDRESSES section for a location to
examine the regulatory evaluation.
