# 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 Agência Nacional de Aviação 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 71772, December 30, 2019).

# 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                           ( print page 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 work-hour).

## 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.

## (h) Retained Restrictions on Alternative Actions, Intervals, and Critical Design Configuration Control Limitations (CDCCLs), With a New Exception

                            This paragraph restates the requirements of paragraph (j) of AD 2019-24-16, with a new exception. Except as required by paragraph (i) of this AD: After the existing maintenance or inspection program has been revised as required by paragraph (g) of this AD, no alternative actions (                            *e.g.,*                             inspections), intervals, or CDCCLs may be used unless the actions, intervals, and CDCCLs are approved as an AMOC in accordance with the procedures specified in paragraph (k)(1) of this AD.                        

## (i) New Revision of the Existing Maintenance or Inspection Program

Except as specified in paragraph (j) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, ANAC AD 2023-12-02.
