AGENCY:
Federal Aviation Administration (FAA), DOT.
ACTION:
Final rule.
SUMMARY:
The FAA is adopting a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes. This AD was prompted by a manufacturing quality escape concerning certain overheat detection system (ODS) sensing elements. This AD requires inspecting the ODS sensing elements and performing applicable corrective actions, and prohibits the installation of affected parts, 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 November 29, 2024.
The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of November 29, 2024.
ADDRESSES:
AD Docket: You may examine the AD docket at regulations.gov under Docket No. FAA-2024-1704; or in person at Docket Operations between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains this final rule, the mandatory continuing airworthiness information (MCAI), any comments received, and other information. The address for Docket Operations is U.S. Department of Transportation, Docket Operations, M-30, West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue SE, Washington, DC 20590.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes. The NPRM published in the Federal Register on July 16, 2024 (89 FR 57795). The NPRM was prompted by AD 2023-11-02, effective November 21, 2023, issued by ANAC, which is the aviation authority for Brazil (ANAC AD 2023-11-02) (also referred to as the MCAI). The MCAI states that a quality escape occurred during manufacturing concerning some ODS sensing elements produced before January 31, 2021.
In the NPRM, the FAA proposed to require inspecting the ODS sensing elements and performing applicable corrective actions, as specified in ANAC AD 2023-11-02. The NPRM also proposed to prohibit the installation of affected parts. The FAA is issuing this AD to address defective sensing elements. The unsafe condition, if not addressed, could result in a sensing element not being able to detect a thermal bleed leak, which is a latent failure, and, depending on the affected area, may start an ignition source in the fuel tank, which could damage some electronic boxes and expose the wing structure to high temperature gradients and unexpected thermal loads, which could result in reduced structural integrity of the airplane.
You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA-2024-1704.
Discussion of Final Airworthiness Directive
Comments
The FAA received a comment from Air Line Pilots Association, International (ALPA), who supported the NPRM without change.
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, considered the comment received, and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD 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 2023-11-02 specifies procedures for a detailed inspection of the ODS sensing elements of the airplane bleed lines and replacement, if applicable, and procedures for re-activation of ODS sensing elements that were deactivated during the detailed inspection. ANAC AD 2023-11-02 also defines and prohibits the installation of an affected ODS sensing element unless the affected part passed an inspection, indicated by a marking on one face of the connector hex nut.
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 90 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions
| Labor cost | Parts cost | Cost per product | Cost on U.S. operators |
|---|---|---|---|
| Up to 26 work-hours × $85 per hour = Up to $2,210 | $0 | Up to $2,210 | Up to $198,900. |
Estimated Costs of On-Condition Actions
| Labor cost | Parts cost | Cost per product |
|---|---|---|
| 2 work-hours × $85 per hour = $170 | $500 | $670 |
