14 CFR Part 39

[Docket No. FAA-2023-1717; Project Identifier MCAI-2023-00728-A; 
Amendment 39-22578; AD 2023-21-06]

Airworthiness Directives; Embraer S.A. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Embraer S.A. (Embraer) Model EMB-505 airplanes. This AD was 
prompted by analysis of certain monuments (the right-hand refreshment 
center and left-hand forward cabinet) that identified the need for 
installing structural reinforcements and replacing certain floor 
support rivets. This AD requires installing structural reinforcements 
on certain monuments and replacing certain floor support rivets, 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 December 11, 2023.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of December 11, 
2023.

ADDRESSES: 
    AD Docket: You may examine the AD docket at regulations.gov under 
Docket No. FAA-2023-1717; or in person at Docket Operations between 9 
a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD 
docket contains this final rule, the mandatory continuing airworthiness 
information (MCAI), any comments received, and other information. The

SUPPLEMENTARY INFORMATION: 

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to certain serial-numbered 
Embraer Model EMB-505 airplanes. The NPRM published in the Federal 
Register on August 24, 2023 (88 FR 57907). The NPRM was prompted by AD 
2023-05-03, effective June 2, 2023, issued by ANAC, which is the 
aviation authority for Brazil (ANAC AD 2023-04-01) (also referred to as 
the MCAI), to correct an unsafe condition for certain serial-numbered 
Embraer Model EMB-505 airplanes. The MCAI states that analysis 
identified certain monuments (the right-hand refreshment center and 
left-hand forward cabinet) that might not withstand the loads expected 
for specific emergency landing conditions, which may cause the 
detachment of mass items and result in injuries to the airplane 
occupants. To address this unsafe condition, the MCAI specifies 
installing structural reinforcements on certain monuments and replacing 
applicable floor support rivets.
    In the NPRM, the FAA proposed to require installing structural 
reinforcements on certain monuments and replacing certain floor support 
rivets, as specified in ANAC AD 2023-04-01. The FAA is issuing this AD 
to address the unsafe condition.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2023-1717.

Discussion of Final Airworthiness Directive

Comments

    The FAA received no comments on the NPRM or on the determination of 
the costs.

Conclusion

    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 referenced above. The FAA reviewed the relevant data and 
determined that air safety requires adopting this AD as proposed. 
Accordingly, the FAA is issuing this AD to address the unsafe condition 
on these products. This AD is adopted as proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    ANAC AD 2023-05-03 specifies procedures for installing structural 
reinforcements on certain monuments and replacing applicable fasteners 
on the floor support.
    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 ADDRESSES.

Differences Between This AD and the MCAI

    The service information specified in ANAC AD 2023-05-03 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 AD requires approval from either the Manager, 
International Validation Branch, FAA; ANAC; or ANAC's authorized 
Designee.

Costs of Compliance

    The FAA estimates that this AD affects 208 airplanes of U.S. 
registry.
    The FAA estimates the following costs to comply with this AD:

    The FAA estimates the following costs for operators that did the 
actions in the original version of Embraer Service Bulletin SB505-25-
0046, dated March 31, 2021. The agency has no way of determining the 
number of airplanes that might need these actions:

[[Page 76116]]

    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, all of the costs of this 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

    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) Will not affect intrastate aviation in Alaska, and
    (3) 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.
