Airworthiness Directives; Embraer S.A. (Type Certificate 
Previously Held by Yabor[atilde] Ind[uacute]stria Aeron[aacute]utica 
S.A.; Embraer S.A.) Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all 
Embraer S.A. Model ERJ 190-300 and -400 airplanes. This AD was prompted 
by identification that, during simulations, analysis, and an in-service 
event of the airplane, a stall warning system activation (i.e., stick 
shaker) and angle of attack (AOA) limiter engagement may occur in 
certain vertical gust conditions with specific intensity and frequency. 
This AD requires revising the Limitations section of the existing 
airplane flight manual (AFM) to incorporate minimum operating speeds 
during flight at moderate or severe turbulence conditions, as specified 
in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, 
which is incorporated by reference. The FAA is issuing this AD to 
address the unsafe condition on these products.

DATES: This AD is effective August 18, 2023.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of August 18, 
2023.

SUPPLEMENTARY INFORMATION: 

Comments Invited

    The FAA invites you to send any written data, views, or arguments 
about this final rule. Send your comments to an address listed under 
ADDRESSES. Include ``Docket No. FAA-2023-1646; Project Identifier MCAI-
2023-00065-T'' at the beginning of your comments. The most helpful 
comments reference a specific portion of the final rule, explain the 
reason for any recommended change, and include supporting data. The FAA 
will consider all comments received by the closing date and may amend 
this final rule because of those comments.
    Except for Confidential Business Information (CBI) as described in 
the following paragraph, and other information as described in 14 CFR 
11.35, the FAA will post all comments received, without change, to 
regulations.gov, including any personal information you provide. The 
agency will also post a report summarizing each substantive verbal 
contact received about this final rule.

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this AD contain commercial 
or financial information that is customarily treated as private, that 
you actually treat as private, and that is relevant or responsive to 
this AD, it is important that you clearly designate the submitted 
comments as CBI. Please mark each page of your submission containing 
CBI as ``PROPIN.'' The FAA will treat such marked submissions as 
confidential under the FOIA, and they will not be placed in the public 
docket of this AD. Submissions containing CBI should be sent to Joshua 
Bragg, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, Suite 410, 
Westbury, NY 11590; telephone 817-222-5366; [email protected]. Any 
commentary that the FAA receives which is not specifically designated 
as CBI will be placed in the public docket for this rulemaking.

Background

    ANAC, which is the aviation authority for Brazil, has issued ANAC 
AD 2023-01-01, effective January 18, 2023 (ANAC AD 2023-01-01) (also 
referred to as the MCAI), to correct an

[[Page 51219]]

unsafe condition for all Embraer S.A. Model ERJ 190-300 and -400 
airplanes. The MCAI states it has been identified that, during 
simulations, analysis, and an in-service event of the airplane, a stall 
warning system activation (i.e., stick shaker) and AOA limiter 
engagement may occur in certain vertical gust conditions with specific 
intensity and frequency. These certain vertical gust conditions, in 
combination with certain weight, speed, and aerodynamic configurations, 
could cause a nose up movement of the airplane after the stick shaker 
activation. This unsafe condition, if not addressed, could induce an 
unexpected airplane response affecting its controllability.
    The FAA is issuing this AD to address the unsafe condition on these 
products.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2023-1646.

Related Service Information Under 1 CFR Part 51

    ANAC AD 2023-01-01 specifies procedures for revising the 
Limitations section of the existing AFM to incorporate certain minimum 
operating speeds during flight at moderate or severe turbulence 
conditions, or if these conditions can be anticipated. 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 in the United States. Pursuant to 
the FAA's bilateral agreement with this State of Design Authority, it 
has notified the FAA of the unsafe condition described in the MCAI 
referenced above. The FAA is issuing this AD after determining that the 
unsafe condition described previously 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 ANAC AD 
2023-01-01 described previously, except for any differences identified 
as exceptions in the regulatory text of this AD.

Compliance With AFM Revision

    FAA regulations require operators furnish to pilots any changes to 
the AFM (for example, 14 CFR 121.137), and to ensure the pilots are 
familiar with the AFM (for example, 14 CFR 91.505). As with any other 
flightcrew training requirement, training on the updated AFM content is 
tracked by the operators and recorded in each pilot's training record, 
which is available for the FAA to review. FAA regulations also require 
pilots to follow the procedures in the existing AFM including all 
updates. Section 91.9 of 14 CFR requires that any person operating a 
civil aircraft must comply with the operating limitations specified in 
the AFM.

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA developed a process to use some civil aviation 
authority (CAA) ADs as the primary source of information for compliance 
with requirements for corresponding FAA ADs. The FAA has been 
coordinating this process with manufacturers and CAAs. As a result, 
ANAC AD 2023-01-01 is incorporated by reference in this AD. This AD 
requires compliance with ANAC AD 2023-01-01 in its entirety through 
that incorporation, except for any differences identified as exceptions 
in the regulatory text of this AD. Service information required by ANAC 
AD 2023-01-01 for compliance will be available at regulations.gov under 
Docket No. FAA-2023-1646 after this AD is published.

FAA's Justification and Determination of the Effective Date

    Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 
U.S.C. 551 et seq.) authorizes agencies to dispense with notice and 
comment procedures for rules when the agency, for ``good cause,'' finds 
that those procedures are ``impracticable, unnecessary, or contrary to 
the public interest.'' Under this section, an agency, upon finding good 
cause, may issue a final rule without providing notice and seeking 
comment prior to issuance. Further, section 553(d) of the APA 
authorizes agencies to make rules effective in less than thirty days, 
upon a finding of good cause.
    There are currently no domestic operators of these products. 
Accordingly, notice and opportunity for prior public comment are 
unnecessary, pursuant to 5 U.S.C. 553(b)(3)(B). In addition, for the 
forgoing reason(s), the FAA finds that good cause exists pursuant to 5 
U.S.C. 553(d) 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.

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
------------------------------------------------------------------------
                                                             Cost per
              Labor cost                   Parts cost        product
------------------------------------------------------------------------
1 work-hour x $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

    This AD will not have federalism implications under Executive Order 
13132. This AD will not have a

[[Page 51220]]

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.
