Airworthiness Directives; Embraer S.A. 

Airplanes 

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 

Ageˆncia Nacional de Aviac ̧a ̃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 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06, ANAC superseded ANAC AD 2023– 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 serialnumbered 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 ADDRESSES.

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

Action Labor cost Parts cost Cost per 

product Cost on U.S. operators 

Airplane groups 1 and 2—install structural reinforcements.22 work-hours × $85 per 

hour = $1,870.

$1,600 $3,470 $242,900 (70 airplanes). 

Airplane groups 3, 4, and 5—install structural reinforcements and replace floor fasteners.14 work-hours × $85 per 

hour = $1,190.

600 1,790 $200,480 (112 airplanes). 

Airplane groups 6 and 8—install structural reinforcements and replace floor fasteners.26 work-hours × $85 per 

hour = $2,210.

2,000 4,210 $84,200 (20 airplanes). 

Airplane group 7—install structural reinforcements .......... 20 work-hours × $85 per 

hour = $1,700.

1,600 3,300 $16,500 (5 airplanes). 

Airplane group 9—install structural reinforcements .......... 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 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

Action Labor cost Parts cost Cost per 

product 

Inspect floor fasteners ................................................................................ 9 work-hours × $85 per hour = $765 ......... $50 $815 

Replace floor fasteners .............................................................................. 1 work-hour × $85 per hour = $85 ............. 50 135 

Airplane groups 1 and 2 install reinforcement support on left-hand forward cabinet.2 work-hours × $85 per hour = $170 ......... 200 370 

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.
