SUPPLEMENTARY INFORMATION:

Discussion

The Agência Nacional de Aviação 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.Start Printed 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

Labor costParts costCost per product
8 work-hours × $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.
