Start Preamble

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Final rule; request for comments.

SUMMARY:

The FAA is adopting a new airworthiness directive (AD) for all Yaborã Indústria Aeronáutica S.A. Model ERJ 190-300 and ERJ 190-400 airplanes. This AD was prompted by a failure propagation test, which revealed that when complete loss of the electrical digital current (DC) essential bus 2 was induced, the smoke detection system of the forward and aft electrical bays erroneously indicated the presence of smoke via the respective engine indication and crew alerting system (EICAS) messages. This AD requires revising the existing airplane flight manual (AFM) procedures associated with messages of smoke in the electronic bays presented on the EICAS, as specified in an Agência Nacional de Aviação Civil (ANAC) Brazilian AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

DATES:

This AD becomes effective May 22, 2020.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of May 22, 2020.

The FAA must receive comments on this AD by June 22, 2020.

SUPPLEMENTARY INFORMATION:

Discussion

The ANAC, which is the aviation authority for Brazil, has issued Brazilian Emergency Airworthiness Directive (EAD) 2019-12-01, effective December 9, 2019 (“Brazilian EAD 2019-12-01”) (also referred to as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for all Yaborã Indústria Aeronáutica S.A. Model ERJ 190-300 and ERJ 190-400 airplanes.

This AD was prompted by a failure propagation test, which revealed that when complete loss of the electrical DC essential bus 2 was induced, the smoke detection system of the forward and aft electrical bays erroneously indicated the presence of smoke via the respective EICAS messages. When these messages are displayed the existing AFM procedures require the flightcrew to turn off the essential electrical buses DC ESS BUS 1 and DC ESS BUS 3, which would result in a loss of all electrical DC essential buses, causing loss of electrical power for critical systems of the airplane.

The FAA is issuing this AD to provide the flightcrew with revised AFM procedures for responding to erroneous indications of smoke in the electrical bays presented on the EICAS. If the flightcrew followed the existing AFM procedures, it could result in a loss of all electrical DC essential buses, causing loss of electrical power for critical systems of the airplane. See the MCAI for additional background information.

Brazilian EAD 2019-12-01 describes revisions to the existing AFM procedures associated with messages of smoke in the electronic bays presented on the EICAS.

This material 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.

FAA's Determination

This product has been approved by the aviation authority of another country, and is approved for operation Start Printed Page 27113in the United States. Pursuant to the FAA's bilateral agreement with the State of Design Authority, the FAA has been notified of the unsafe condition described in the MCAI referenced above. The FAA is issuing this AD after evaluating all pertinent information and determining the unsafe condition exists and is likely to exist or develop on other products of the same type design.

Requirements of This AD

This AD requires accomplishing the actions specified in Brazilian EAD 2019-12-01 described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this AD.

Explanation of Required Compliance Information

In the FAA's ongoing efforts to improve the efficiency of the AD process, the FAA initially worked with Airbus and the European Union Safety Agency (EASA) to develop a process to use certain EASA ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has since coordinated with other manufacturers and civil aviation authorities (CAAs) to use this process. As a result, ANAC Brazilian EAD 2019-12-01 is incorporated by reference in this final rule. This AD, therefore, requires compliance with ANAC Brazilian EAD 2019-12-01 in its entirety, through that incorporation, except for any differences identified as exceptions in the regulatory text of this AD. Service information specified in ANAC Brazilian EAD 2019-12-01 that is required for compliance with ANAC Brazilian EAD 2019-12-01 is available on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2020-0340.

FAA's Justification and Determination of the Effective Date

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

Regulatory Flexibility Act (RFA)

The requirements of the RFA do not apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and comment. Because the FAA has determined that it has good cause to adopt this rule without notice and comment, RFA analysis is not required.

Comments Invited

This AD is a final rule that involves requirements affecting flight safety, and the FAA did not precede it by notice and opportunity for public comment. The FAA invites 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-2020-0340; Product Identifier 2019-NM-203-AD” at the beginning of your comments. The FAA specifically invites comments on the overall regulatory, economic, environmental, and energy aspects of this AD. The FAA will consider all comments received by the closing date and may amend this AD based on those comments.

The FAA will post all comments received, without change, to https://www.regulations.gov, including any personal information you provide. The FAA will also post a report summarizing each substantive verbal contact received 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, the FAA provides the following cost estimates to comply with this AD:

Estimated Costs for Required Actions

Labor costParts costCost per product
1 work-hour × $85 per hour = $85$0$85

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.

The FAA is 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

The FAA 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, and

(2) Will not affect intrastate aviation in Alaska.
