RIN 2120-AA64
Airworthiness Directives; Embraer S.A. Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) for certain
Embraer S.A. (Embraer) Model EMB-505 airplanes. This proposed AD was prompted by
analysis of the left-hand (LH) refreshment center and LH forward cabinet that identified
the need for installing structural reinforcements. This proposed AD would require
installing structural reinforcements as specified in an Agência Nacional de Aviação Civil
(ANAC) AD, which is proposed for incorporation by reference. The FAA is proposing
this AD to address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION:
Comments Invited
The FAA invites you to send any written relevant data, views, or arguments about
this proposal. Send your comments to an address listed under ADDRESSES. Include
“Docket No. FAA-2024-1484; Project Identifier MCAI-2023-00968-A” at the beginning

of your comments. The most helpful comments reference a specific portion of the
proposal, 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
proposal 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 NPRM.
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 NPRM
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 NPRM, 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 NPRM. Submissions containing CBI should be sent to Jim Rutherford,
Aviation Safety Engineer, FAA, 1600 Stewart Avenue, Suite 410, Westbury, NY 11590.
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 2023-0701, effective August 10, 2023, as corrected by ANAC Airworthiness Directive Errata,
effective August 10, 2023 (ANAC AD 2023-07-01) (also referred to as the MCAI) to

correct an unsafe condition on certain serial-numbered Embraer Model EMB-505
airplanes. The MCAI states that analysis identified that the LH refreshment center and
LH forward cabinet might not withstand the loads expected for specific emergency
landing conditions, which may cause the detachment of mass items and cause injuries to
the airplane occupants. In addition, the MCAI includes errata to correct a printing error in
the original English version of the MCAI. The MCAI requires installing structural
reinforcements.
You may examine the MCAI in the AD docket at regulations.gov under Docket
No. FAA-2024-1484.
Related Service Information under 1 CFR Part 51
The FAA reviewed ANAC AD 2023-07-01, which specifies procedures for
installing structural reinforcements.
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
ADDRESSES.
FAA’s Determination
These products have been approved by the aviation authority of another country
and are 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 described above. The FAA is issuing this NPRM after
determining that the unsafe condition described previously is likely to exist or develop on
other products of the same type design.
Proposed AD Requirements in this NPRM
This proposed AD would require accomplishing the actions specified in ANAC
AD 2023-07-01, except for any differences identified as exceptions in the regulatory text

of this proposed AD and except as discussed under “Differences Between this Proposed
AD and the MCAI.”
Differences Between This Proposed AD and the MCAI
The service information specified in ANAC AD 2023-07-01 allows the use of
alternative or similar parts in place of the ones specified in the kits, provided these
alternative or similar parts are approved by Embraer, but this proposed AD would require
approval from either the Manager, International Validation Branch, FAA; ANAC; or
ANAC's authorized Designee.
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,
the FAA proposes to incorporate ANAC AD 2023-07-01 by reference in the FAA final
rule. This proposed AD would, therefore, require compliance with ANAC AD 2023-0701 in its entirety through that incorporation, except for any differences identified as
exceptions in the regulatory text of this proposed AD. Service information required by
ANAC AD 2023-07-01 will be available at regulations.gov under Docket No. FAA2024-1484 after the FAA final rule is published.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would affect 229
airplanes of U.S. registry.
The FAA estimates the following costs to comply with this proposed AD.

Estimated costs
Action

Labor Cost

Install structural 11 work-hours
reinforcements x $85 per hour
= $935

Parts Cost
$1,600

Cost per
product
$2,535

Cost on U.S.
operators
$580,515

The FAA has included all known costs in its cost estimate. According to the
manufacturer, however, some or all of the costs of this proposed AD may be covered
under warranty, thereby reducing the cost impact on affected operators.
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 proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 this proposed regulation:
(1) Is not a “significant regulatory action” under Executive Order 12866,
(2) Would not affect intrastate aviation in Alaska, and
(3) Would not have a significant economic impact, positive or negative, on a
substantial number of small entities under the criteria of the Regulatory Flexibility Act.
List of Subjects in 14 CFR Part 39
