SUPPLEMENTARY INFORMATION:

Discussion

    The Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC), 
which is the aviation authority for Brazil, has issued Brazilian AD 
2001-05-03R3, dated April 22, 2003 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for all Empresa Brasileira de Aeronautica 
S.A. (Embraer) Model EMB-135 airplanes and Model EMB-145, 145ER, -
145MR, -145LR, -145XR, -145MP, and 145EP airplanes. The MCAI states:

    There have been found cases of internal corrosion of the stow/
transit switches installed in the engine thrust reversers of EMB-145 
( ) aircraft models. One case of severely contaminated transit 
switch resulted in uncommanded engine rollback to idle in flight. 
Spurious messages ``ENG ( ) REV DISAGREE'' have also been displayed 
in the [Engine Indicating and Crew Alerting System] EICAS, due to 
the above internal corrosion, which have induced aborted takeoffs.
    Since this condition may occur in other airplanes of the same 
type and affects flight safety, a corrective action [installation of 
stow/transit switches] is required. Thus, sufficient reason exists 
to request compliance with this [Brazilian] AD in the indicated time 
limit.

    You may examine the MCAI on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2019-
0118.

Relationship Between This AD and AD 2004-13-16, Amendment 39-13698 (69 
FR 38819, June 29, 2004) (``AD 2004-13-16'')

    We issued AD 2004-13-16 to correspond to the MCAI. However, AD 
2004-13-16 referenced Embraer Service Bulletin 145-78-0035, Revision 
02, dated January 31, 2003, which has been revised to include 
additional airplanes. We have determined that not all affected 
airplanes were listed in Embraer Service Bulletin 145-78-0035, Revision 
02, dated January 31, 2003.
    This final rule does not supersede AD 2004-13-16. Rather, we have 
determined that a stand-alone AD is more appropriate to address the 
airplanes that were not identified in the applicability of AD 2004-13-
16.

Related Service Information Under 1 CFR Part 51

    Embraer issued Service Bulletin 145-78-0035, Revision 03, dated 
November 26, 2004. This service information describes procedures for 
installing new stow/transit switches having part number 83-990-168 on 
both engines. This service information is reasonably available because 
the interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section.
    Embraer also issued Service Bulletin 145-78-0035, Revision 02, 
dated January 31, 2003, which the Director of the Federal Register 
approved for incorporation by reference as of August 3, 2004 (69 FR 
38819, June 29, 2004).

FAA's Determination

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are issuing this AD because we 
evaluated all pertinent information and determined the unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

[[Page 8606]]

Requirements of This AD

    This AD requires accomplishing the actions specified in the service 
information described previously.

FAA's Justification and Determination of the Effective Date

    Since there are currently no domestic operators of this product, 
notice and opportunity for public comment before issuing this AD are 
unnecessary. In addition, for the reason stated above, we find that 
good cause exists for making this amendment effective in less than 30 
days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2019-0118; Product 
Identifier 2018-NM-143-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD based on 
those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    Currently, there are no affected U.S.-registered airplanes. If an 
affected airplane is imported and placed on the U.S. Register in the 
future, we provide the following cost estimates to comply with this AD:

                  Estimated Costs for Required Actions
------------------------------------------------------------------------
                                                             Cost per
              Labor cost                   Parts cost        product
------------------------------------------------------------------------
8 work-hours x $85 per hour = $680....            $194             $874
------------------------------------------------------------------------

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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes and 
associated appliances to the Director of the System Oversight Division.

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 that 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);
    3. Will not affect intrastate aviation in Alaska; and
    4. 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.
