 Department of Transportation Federal Aviation Administration 14 CFR Part 39
[Docket No. FAA-2024-2020; Project Identifier MCAI-2024-00303-A; Amendment 39-22877; AD 2024-22-06]
RIN 2120-AA64
 AGENCY: Federal Aviation Administration (FAA), DOT.
 ACTION: Final rule.
 SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2023-21-06 for certain Embraer S.A. (Embraer) Model EMB-505 airplanes. AD 2023-21-06 required installing structural reinforcements on certain monuments and replacing certain floor support rivets. Since the FAA issued AD 2023-21-06, the FAA determined that certain airplanes need to be re-assigned to a different group and certain re-identified floor support part numbers need to be corrected. This AD requires installing structural reinforcements on monuments and replacing fasteners on the floor support, as specified in an Agência Nacional de Aviação 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 January 2, 2025. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of January 2, 2025.

SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2023-21-06, Amendment 39-22578 (88 FR 76114, November 6, 2023; corrected December 7, 2023 (88 FR 85093)) (AD 2023-21-06). AD 2023-21-06 applied to certain serial-numbered Embraer Model EMB-505 airplanes. AD 2023-21-06 was prompted by an MCAI originated by ANAC, which is the aviation authority for Brazil. ANAC issued ANAC AD 2023-05-03, effective June 2, 2023 (ANAC AD 2023-05-03) to correct an unsafe condition. AD 2023-21-06 required installing structural reinforcements on certain monuments and replacing certain floor support rivets. The FAA issued AD 2023-21-06 to address 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. Since the FAA issued AD 2023-21-06, ANAC superseded ANAC AD 2023-05-03 and issued ANAC AD 2023-05-03R01, effective March 8, 2024 (ANAC AD 2023-05-03R01) for certain serial-numbered Embraer Model EMB-505 airplanes. ANAC AD 2023-05-03R01 stated it was issued to incorporate Embraer Service Bulletin SB505-25-0046, Revision 02, dated February 19, 2024, which updates effectivity information, compliance information, and part number information. ANAC superseded ANAC AD 2023-05-03R01 and issued ANAC AD 2023-05-03R02, effective May 17, 2024 (ANAC AD 2023-05-03R02) (also referred to as the MCAI) for certain serial-numbered Embraer Model EMB-505 airplanes. The MCAI states it was issued to incorporate Embraer Service Bulletin SB505-25-0046, Revision 03, dated May 6, 2024 (actual date May 7, 2024), which includes additional actions for certain airplane groups that had complied with the requirements of ANAC AD 2023-05-03R01 but had not yet installed part number 506-66837-001 and updates the effectivity information, compliance information, and part number information. The NPRM published in the 
                    **Federal Register**
                     on August 16, 2024 (89 FR 66642). The NPRM was prompted by ANAC AD 2023-05-03R02. In the NPRM, the FAA proposed to require installing structural reinforcements on monuments and replacing fasteners on the floor support, as specified in ANAC AD 2023-05-03R02. The FAA is issuing this AD to address certain monuments 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. You may examine the MCAI in the AD docket at 
                    *regulations.gov*
                     under Docket No. FAA-2024-2020. 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. Material Incorporated by Reference Under 1 CFR Part 51 The FAA reviewed ANAC AD 2023-05-03R02, which specifies procedures for installing structural reinforcements on certain monuments and replacing certain 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

                    ( print page 93473) Differences Between This AD and the MCAI The material specified in ANAC AD 2023-05-03R02 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. If approved by the ANAC Designee, the approval must include the Designee's authorized signature. 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: Estimated Costs

 The FAA estimates the following costs for the additional work that operators would be required to do for compliance with this AD if they completed the actions in the original version of Embraer Service Bulletin SB505-25-0046, dated March 31, 2021; Service Bulletin SB505-25-0046, Revision 01, dated May 8, 2023; or Service Bulletin SB505-25-0046, Revision 02, dated February 19, 2024. The agency has no way of determining the number of airplanes that might need these actions: On-Condition Costs

 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 The FAA has 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, (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.
