1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. 2. The FAA amends § 39.13 by adding the following new airworthiness directive: 2026-10-01 Embraer S.A. (Type Certificate Previously Held by Yaborã Indústria Aeronáutica S.A.; Embraer S.A.): Amendment 39-23341; Docket No. FAA-2026-1340; Project Identifier MCAI-2024-00430-T. (a) Effective Date This airworthiness directive (AD) is effective June 26, 2026. (b) Affected ADs None. (c) Applicability This AD applies to Embraer S.A. (Type Certificate previously held by Yaborã Indústria Aeronáutica S.A.; Embraer S.A.) Model ERJ 190-100 ECJ airplanes, certificated in any category, as identified in Agência Nacional de Aviação Civil (ANAC) AD 2024-07-01, effective July 31, 2024 (ANAC AD 2024-07-01). (d) Subject Air Transport Association (ATA) of America Code 26, Fire Protection; 36, Pneumatic. (e) Unsafe Condition This AD was prompted by a manufacturing quality escape concerning certain overheat detection system (ODS) sensing elements. The FAA is issuing this AD to address defective sensing elements. The unsafe condition, if not addressed, could lead to an undetected thermal bleed leak that could start an ignition source in the fuel tank, damaging some electronic boxes and exposing the wing structure to high temperature gradients and unexpected thermal loads, which could result in reduced structural integrity of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Requirements Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, ANAC AD 2024-07-01. (h) Exceptions to ANAC AD 2024-07-01 (1) Where ANAC AD 2024-07-01 refers to its effective date, this AD requires using the effective date of this AD. (2) Where paragraphs (b)(1) and (c)(1) of ANAC AD 2024-07-01 specify to inspect the ODS sensing elements of various "areas of the airplane", this AD requires replacing that text with "areas of the airplane in accordance with Embraer Service Bulletin 190LIN-36-0013, Revision 03, dated April 20, 2024; or later revisions approved by ANAC". (3) Where paragraphs (b) and (c) of ANAC AD 2024-07-01 specify on-condition actions based on the results of the ODS sensing element inspections required by paragraphs (b)(1) and (c)(1) of ANAC AD 2024-07-01, this AD requires performing all applicable on-condition actions before further flight after each inspection. (4) This AD does not adopt paragraph (f) of ANAC AD 2024-07-01. (i) Additional AD Provisions The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, AIR-520, Continued Operational Safety Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or responsible Flight Standards Office, as appropriate. If sending information directly to the manager of the Continued Operational Safety Branch, send it to the attention of the person identified in paragraph (j) of this AD and email to: AMOC@faa.gov . Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the responsible Flight Standards Office. (2) Contacting the Manufacturer: For any requirement in this AD to obtain instructions from a manufacturer, the instructions must be accomplished using a method approved by the Manager, AIR-520, Continued Operational Safety Branch, FAA; or ANAC; or ANAC's authorized Designee. If approved by the ANAC Designee, the approval must include the Designee's authorized signature. (3) Required for Compliance (RC): Except as required by paragraph (i)(2) of this AD, if any material contains steps in the Accomplishment Instructions or figures that are labeled as RC, the instructions in RC steps, including subparagraphs under an RC step and any figures identified in an RC step, must be done to comply with this AD; any steps including substeps under those steps, that are not identified as RC are recommended. The instructions in steps, including substeps under those steps, not identified as RC may be deviated from using accepted methods in accordance with the operator's maintenance or inspection program without obtaining approval of an AMOC, provided the instructions identified as RC can be done and the airplane can be put back in an airworthy condition. Any substitutions or changes to instructions identified as RC require approval of an AMOC. If a step or substep is labeled "RC Exempt," then the RC requirement is removed from that step or substep.
