Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: The FAA proposes to supersede Airworthiness Directive (AD) 2023–21–06, which applies to certain Embraer S.A. (Embraer) Model EMB– 505 airplanes. AD 2023–21–06 requires installing structural reinforcements on certain monuments and replacing certain floor support rivets. Since the FAA issued AD 2023–21–06, the FAA has 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 proposed AD would require 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 proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products. SUMMARY: The FAA must receive comments on this NPRM by September 30, 2024.

Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background The FAA issued AD 2023–21–06, Amendment 39–22578 (88 FR 85093, December 7, 2023) (AD 2023–21–06), for 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 requires 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. Actions Since AD 2023–21–06 Was Issued Since the FAA issued AD 2023–21– 06, ANAC superseded ANAC AD 2023– 05–03 and issued ANAC AD 2023–05– 03R01, effective March 8, 2024 (ANAC AD 2023–05–03R01) for certain serialnumbered Embraer Model EMB–505 airplanes. ANAC AD 2023–05–03R01 states 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 ANAC superseded ANAC AD 2023– 05–03R01 and issued ANAC AD 2023– 05–03R02, effective May 17, 2024 (ANAC AD 2023–05–03R02) (also referred to as the MCAI) for certain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 E:\FR\FM\16AUP1.SGM 16AUP1 66643 Federal Register / Vol. 89, No. 159 / Friday, August 16, 2024 / Proposed Rules 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 (P/N) 506– 66837–001 and updates the effectivity information, compliance information, and part number information. 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. 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 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 referenced 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 2023–05–03R02 described previously, 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 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 proposed AD would require 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. 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 2023–05–03R02 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with ANAC AD 2023–05– 03R02 in its entirety through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD. Material required by ANAC AD 2023– 05–03R02 for compliance will be available at regulations.gov under Docket No. FAA–2024–2020 after the FAA final rule is published. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 208 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: ESTIMATED COSTS Labor cost Airplane groups 1 and 2—install structural reinforcements. Airplane groups 3, 4, and 5—install structural reinforcements and replace floor fasteners. Airplane groups 6 and 8—install structural reinforcements and replace floor fasteners. Airplane group 7—install structural reinforcements. Airplane group 9—install structural reinforcements. 22 work-hours × $85 per hour = $1,870 $1,600 $3,470 $242,900 (70 airplanes). 14 work-hours × $85 per hour = $1,190 600 1,790 $200,480 (112 airplanes). 26 work-hours × $85 per hour = $2,210 2,000 4,210 $84,200 (20 airplanes). 20 work-hours × $85 per hour = $1,700 1,600 3,300 $16,500 (5 airplanes). 14 work-hours × $85 per hour = $1,190 1,600 2,790 $2,790 (1 airplane). The FAA estimates the following costs for the additional work that operators would be required to do for compliance with this proposed AD if they completed the actions in the lotter on DSK11XQN23PROD with PROPOSALS1 Cost per product Action Parts cost 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, Cost on U.S. operators Revision 02, dated February 19, 2024. The agency has no way of determining the number of airplanes that might need these actions: ESTIMATED COSTS Action Labor cost Inspect floor fasteners .................................................................... Replace floor fasteners .................................................................. 9 work-hours × $85 per hour = $765 .......... 1 work-hour × $85 per hour = $85 .............

The FAA has included all known costs in its cost estimate. According to the manufacturer, however, 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. lotter on DSK11XQN23PROD with PROPOSALS1 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 that the 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.

SUPPLEMENTARY INFORMATION: Background The IASA program is the means by which the FAA determines whether another country’s oversight of its air carriers that (1) operate, or seek to operate, services to/from the United States using their own aircraft and crews, or (2) seek to display the code of a U.S. air carrier on any services, complies with safety standards established by the International Civil Aviation Organization (ICAO). The published IASA results of a country’s placement in Category 1 or Category 2 is the notification to the U.S. traveling public as to whether a foreign air carrier’s homeland civil aviation PO 00000 Frm 00007 Fmt 4702 Sfmt 4702 66645 authority meets ICAO safety standards. A Category 1 rating indicates that the civil aviation authority meets ICAO safety standards for these operations, and a Category 2 rating indicates that the civil aviation authority does not meet ICAO safety standards. The IASA program was established by a document published in the Federal Register in 1992. Subsequent published documents in the Federal Register notified of the program’s evolution. These Federal Register documents are as follows: • August 24, 1992—Established the FAA Procedures for Examining and Monitoring Foreign Air Carriers (57 FR 38342). • September 8, 1994—Established the Public Disclosure of the Results of Foreign Civil Aviation Authority Assessments, through a three-category numbered rating system (59 FR 46332). • October 31, 1995—DOT Notice Clarification Concerning Examination of Foreign Carriers’ Request for Expanded Economic Authority, clarified the Department’s licensing policy regarding requests for expanded economic authority from foreign air carriers whose CAA’s safety oversight capability has been assessed by the FAA as conditional (Category II) or unacceptable (Category III) (60 FR 55408). • May 25, 2000—Changes to the International Aviation Safety Assessment program removed the Category 3 rating and combined it with Category 2 (65 FR 33751). • March 8, 2013—Changes to the International Aviation Safety Assessment program removed inactive countries (countries with no air carrier operations to the United States or codeshares with U.S. air carrier for four years and no significant interaction between the country’s CAA and the FAA) from the IASA Category list (78 FR 14912). Through the IASA program, the FAA seeks continuous improvement to global aviation safety. As noted in the abovereferenced policy statement of September 8, 1994, initial IASA assessments found that two-thirds of the assessed CAAs were deficient in meeting their safety oversight obligations under the Convention on International Civil Aviation. The September 28, 2022, Policy Statement (87 FR 58725) (now suspended) announced certain changes to the IASA program and provided clarification to other aspects of the IASA policy. Since that publication, the FAA and DOT have received inquiries and questions that warrant reassessment of those changes and clarifications, and an opportunity for public comment before they are adopted permanently. As noted above, the FAA is suspending E:\FR\FM\16AUP1.SGM 16AUP1

Airworthiness Directives; Embraer S.A. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 
2023-21-06, which applies to certain Embraer S.A. (Embraer) Model EMB-
505 airplanes. AD 2023-21-06 requires installing structural 
reinforcements on certain monuments and replacing certain floor support 
rivets. Since the FAA issued AD 2023-21-06, the FAA has 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 proposed AD would require installing structural reinforcements on 
monuments and replacing fasteners on the floor support, as specified in 
an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, 
which is proposed for incorporation by reference. The FAA is proposing 
this AD to address the unsafe condition on these products.

DATES: The FAA must receive comments on this NPRM by September 30, 
2024.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Background

    The FAA issued AD 2023-21-06, Amendment 39-22578 (88 FR 85093, 
December 7, 2023) (AD 2023-21-06), for 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 requires 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.

Actions Since AD 2023-21-06 Was Issued

    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 states 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

[[Page 66643]]

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 (P/N) 506-66837-001 and updates the 
effectivity information, compliance information, and part number 
information.
    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.

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 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 referenced 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 2023-05-03R02 described previously, 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 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 proposed AD would require 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.

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 2023-05-03R02 by reference in the 
FAA final rule. This proposed AD would, therefore, require compliance 
with ANAC AD 2023-05-03R02 in its entirety through that incorporation, 
except for any differences identified as exceptions in the regulatory 
text of this proposed AD. Material required by ANAC AD 2023-05-03R02 
for compliance will be available at regulations.gov under Docket No. 
FAA-2024-2020 after the FAA final rule is published.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 208 airplanes of U.S. registry.
    The FAA estimates the following costs to comply with this proposed 
AD:

                                                 Estimated Costs

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

    The FAA estimates the following costs for the additional work that 
operators would be required to do for compliance with this proposed 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:

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

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

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
