AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2019–24– 

16, which applied to certain Embraer 

S.A. Model ERJ 190–100 STD, –100 LR, 

–100 IGW, and –100 ECJ airplanes; and 

Model ERJ 190–200 STD, –200 LR, and 

–200 IGW airplanes. AD 2019–24–16 

required revising the existing 

maintenance or inspection program, as 

applicable, to incorporate new or more 

restrictive airworthiness limitations. 

Since the FAA issued AD 2019–24–16, 

the FAA has determined that new or 

more restrictive airworthiness 

limitations are necessary. This AD 

requires revising the existing 

maintenance or inspection program, as 

applicable, to incorporate new or more 

restrictive airworthiness limitations, as 

specified in an Ageˆncia Nacional de 

Aviac ̧a ̃o Civil (ANAC) AD, which is 

incorporated by reference (IBR). The 

FAA is issuing this AD to address the 

unsafe condition on these products. 

DATES: This AD is effective November 4, 

2024. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of November 4, 2024. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain other publications listed in 

this AD as of February 3, 2020 (84 FR

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2019–24–16, 

Amendment 39–21005 (84 FR 71772, 

December 30, 2019) (AD 2019–24–16). 

AD 2019–24–16 applied to certain 

Embraer S.A. Model ERJ 190–100 STD, 

–100 LR, –100 IGW, and –100 ECJ 

airplanes; and Model ERJ 190–200 STD, 

–200 LR, and –200 IGW airplanes. AD 

2019–24–16 required revising the 

existing maintenance or inspection 

program, as applicable, to incorporate 

new or more restrictive airworthiness 

limitations. The FAA issued AD 2019– 

24–16 to address fatigue cracking of 

structural components and to address 

failure of certain system components, 

which could result in reduced structural 

integrity and system reliability of the 

airplane. 

The NPRM published in the Federal 

Register on April 4, 2024 (89 FR 23529). 

The NPRM was prompted by AD 2023– 

12–02, effective December 15, 2023, 

issued by ANAC, which is the aviation 

authority for Brazil (ANAC AD 2023– 

12–02) (also referred to as the MCAI), 

for certain Embraer S.A. Model ERJ 190– 

100 STD, –100 LR, –100 IGW, –100 SR, 

and –100 ECJ airplanes; and Model ERJ 

190–200 STD, –200 LR, and –200 IGW 

airplanes. Model ERJ 190–100SR 

airplanes are not on the U.S. Register; 

this AD therefore does not include those 

airplanes in the applicability. The MCAI 

states that new or more restrictive 

airworthiness limitations have been 

developed. 

In the NPRM, the FAA proposed to 

retain all requirements of AD 2019–24– 

16, and require revising the existing 

maintenance or inspection program, as 

applicable, to incorporate additional 

new or more restrictive airworthiness 

limitations, as specified in ANAC AD 

2023–12–02. The FAA is issuing this 

AD to address failure of certain system 

components. The unsafe condition, if 

not addressed, could result in reduced 

structural integrity and system 

reliability of the airplane. 

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2024–0994. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received no comments on 

the NPRM or on the determination of 

the cost to the public. 

Conclusion 

This product has been approved by 

the aviation authority of another 

country and is 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 


ddrumheller on DSK120RN23PROD with RULES1
Federal Register / Vol. 89, No. 189 / Monday, September 30, 2024 / Rules and Regulations 79417 

to address the unsafe condition on this 

product. Except for minor editorial 

changes, this AD is adopted as proposed 

in the NPRM. None of the changes will 

increase the economic burden on any 

operator. 

Material Incorporated by Reference 

Under 1 CFR Part 51 

ANAC AD 2023–12–02 specifies 

procedures for new or more restrictive 

airworthiness limitations for airplane 

structures and safe life limits. 

This AD also requires the following 

documents, which the Director of the 

Federal Register approved for 

incorporation by reference as of 

February 3, 2020 (84 FR 71772, 

December 30, 2019). 

• Appendix A—Airworthiness 

Limitations (AL), to the EMBRAER 190/ 

195 Maintenance Review Board Report, 

MRB–1928, Revision 12, dated 

September 27, 2018. 

• Appendix A—Airworthiness 

Limitations (AL), to the EMBRAER 

Lineage 1000/1000E Maintenance 

Planning Guide, MPG–2928, Revision 8, 

dated October 10, 2018. 

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 the ADDRESSES section. 

Costs of Compliance 

The FAA estimates that this AD 

affects 98 airplanes of U.S. registry. The 

FAA estimates the following costs to 

comply with this AD: 

The FAA estimates the total cost per 

operator for the retained actions from 

AD 2019–24–16 to be $7,650 (90 

workhours × $85 per work-hour). 

The FAA has determined that revising 

the existing maintenance or inspection 

program takes an average of 90 

workhours per operator, although the 

agency recognizes that this number may 

vary from operator to operator. Since 

operators incorporate maintenance or 

inspection program changes for their 

affected fleet(s), the FAA has 

determined that a per-operator estimate 

is more accurate than a per-airplane 

estimate. 

The FAA estimates the total cost per 

operator for the new actions to be 

$7,650 (90 work-hours × $85 per workhour). 

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.

Airworthiness Directives; Airbus SAS 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

Airbus SAS Model A330–243, –302, 

–343, and –941 airplanes. This AD was 

prompted by a determination that a 

certain aft bulkhead cover panel may 

have been made with a non-conforming 

material. This AD requires replacing the 

aft bulkhead cover panel and prohibits 

the installation of affected parts, as 

specified in a European Union Aviation 

Safety Agency (EASA) 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 November 4, 

2024. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of November 4, 2024.
