Abstract
The FAA is adopting a new airworthiness directive (AD) for all Embraer S.A. Model EMB-545 and EMB-550 airplanes. This AD was prompted by a report of a hard landing event with substantial damage to the airplane, in which the angle of attack (AOA) limiter was engaged during the final approach phase in unstable air conditions and remained engaged until the airplane touched down on the runway. This AD requires revising the Limitations and Normal Procedures sections of the existing airplane flight manual (AFM) to incorporate new operational airspeed limitations, and flight control limitations and approach procedures when AOA limiter protection is engaged, as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, which is incorporated by reference. This AD also requires inspecting records for instances of AOA limiter engagement during a certain phase of flight and reporting findings to the FAA. The FAA is issuing this AD to address the unsafe condition on these products.

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all
Embraer S.A. Model EMB-545 and EMB-550 airplanes. This AD was prompted
by a report of a hard landing event with substantial damage to the
airplane, in which the angle of attack (AOA) limiter was engaged during
the final approach phase in unstable air conditions and remained
engaged until the airplane touched down on the runway. This AD requires
revising the Limitations and Normal Procedures sections of the existing
airplane flight manual (AFM) to incorporate new operational airspeed
limitations, and flight control limitations and approach procedures
when AOA limiter protection is engaged, as specified in an
Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, which
is incorporated by reference. This AD also requires inspecting records
for instances of AOA limiter engagement during a certain phase of
flight and reporting findings to the FAA. The FAA is issuing this AD to
address the unsafe condition on these products.

Background
ANAC, which is the aviation authority for Brazil, has issued ANAC
AD 2024-02-02, effective February 26, 2024 (ANAC AD 2024-02-02) (also
referred to after this as the MCAI), to correct an unsafe condition for
all Embraer S.A. Model EMB-545 and EMB-550 airplanes. The MCAI states
that a hard landing event with substantial damage to the airplane was
reported, in which the AOA limiter was engaged during the final
approach phase in unstable air conditions and remained engaged until
the airplane touched down on the runway. If the AOA limiter remains
engaged during the final approach phase when the landing flare
[[Page 20847]]
is commanded, pitch response could be reduced during a critical phase
of flight near the ground; in unstable air conditions, this condition
could result in a high-rate-of-descent landing and the possible
consequent catastrophic structural damage of the airplane on landing.
The FAA is issuing this AD to address the unsafe condition on these
products.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2024-0469.
Related Material Under 1 CFR Part 51
ANAC AD 2024-02-02 specifies procedures for revising the
Limitations and Normal Procedures sections of the existing AFM to
incorporate operational airspeed limitations, and flight control
limitations and approach procedures when AOA limiter protection is
engaged. 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
2024-02-02 described previously, except for any differences identified
as exceptions in the regulatory text of this AD and except as discussed
under ``Differences Between this AD and the MCAI.''
Compliance With AFM Revisions
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. 14 CFR 91.9 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 2024-02-02 is incorporated by reference in this AD. This AD
requires compliance with ANAC AD 2024-02-02 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 2024-02-02 for compliance will be available at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2024-0469 after this AD is published.
Differences Between This AD and the MCAI
This AD requires inspecting all airplane records for instances of
AOA limiter engagement that occur after passing the final approach fix
inbound, or within 5 miles of the intended point of landing if a final
approach fix is not required, and reporting findings to the FAA. The
compliance time for the records inspection is at intervals not to
exceed 30 days after the effective date of this AD for 12 months after
the effective date of this AD. The compliance time for reporting is
within 10 days after each records inspection.
Interim Action
The FAA considers that this AD is an interim action. If final
action is later identified, the FAA might consider further rulemaking
then.
Justification for Immediate Adoption 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.
An unsafe condition exists that requires the immediate adoption of
this AD without providing an opportunity for public comments prior to
adoption. The FAA has found that the risk to the flying public
justifies forgoing notice and comment prior to adoption of this rule
because if the AOA limiter remains engaged during the final approach
phase when the landing flare is commanded, pitch response could be
reduced during a critical phase of flight near the ground; in unstable
air conditions, this condition could result in a high-rate-of-descent
landing and consequent catastrophic structural damage of the airplane
on landing. Accordingly, notice and opportunity for prior public
comment are impracticable and contrary to the public interest pursuant
to 5 U.S.C. 553(b)(3)(B).
In addition, 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,
for the same reasons the FAA found good cause to forgo notice and
comment.
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
The FAA estimates that this AD affects 121 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:

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 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.
List of Subjects in 14 CFR Part 39

The Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive:
2024-05-13 Embraer S.A.: Amendment 39-22705; Docket No. FAA-2024-
0469; Project Identifier MCAI-2024-00137-T.
(a) Effective Date
This airworthiness directive (AD) is effective April 10, 2024.
(b) Affected ADs
None.
(c) Applicability
This AD applies to all Embraer S.A. Model EMB-545 and EMB-550
airplanes, certificated in any category.
(d) Subject
Air Transport Association (ATA) of America Code 22, Auto Flight.
(e) Unsafe Condition
This AD was prompted by a report of a hard landing event with
substantial damage to the airplane, in which the angle of attack
(AOA) limiter was engaged during the final approach phase in
unstable air conditions and remained engaged until the airplane
touched down on the runway. The FAA is issuing this AD to address
AOA limiter engagement during the final approach phase when the
landing flare is commanded, which could reduce pitch response during
a critical phase of flight near the ground. In unstable air
conditions, this condition, if not addressed, could result in a
high-rate-of-descent landing and consequent catastrophic structural
damage to the airplane on landing.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Requirements
Except as specified in paragraphs (h) and (i) of this AD: Comply
with all required actions and compliance times specified in, and in
accordance with, Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o
Civil (ANAC) AD 2024-02-02, effective February 26, 2024 (ANAC AD
2024-02-02).
Note 1 to paragraph (g): Embraer EMB-545/EMB-550 Stall
Protection, General Publication GP-8073, Revision 1, dated February
16, 2024, provides additional guidance regarding the actions
required by this AD.
(h) Exceptions to ANAC AD 2024-02-02
(1) Where ANAC AD 2024-02-02 refers to its effective date, this
AD requires using the effective date of this AD.

operator must inspect all aircraft records for instances of AOA
limiter engagement that occur after passing the final approach fix
inbound, or within 5 miles of the intended point of landing if a
final approach fix is not required. Repeat the inspection thereafter
at intervals not to exceed 30 days until 12 months after the
effective date of this AD. One report per operator may include
multiple aircraft for the same operator for that inspection.
(2) Within 10 days after the records inspection required in
paragraph (i)(1) of this AD, report the results of the inspection,
regardless of whether the inspection found any entries, to the FAA
by either email: <a href="/cdn-cgi/l/email-protection#340d1975677b1975607875777b19757047745255551a535b42"><span class="__cf_email__" data-cfemail="a59c88e4f6ea88e4f1e9e4e6ea88e4e1d6e5c3c4c48bc2cad3">[email protected]</span></a>; or mail: Attn: Continued
