2024-14-08: Pneumatic System

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: 2024-14-08 Embraer S.A. (Type Certificate Previously Held by Yaborã Indústria Aeronáutica S.A.; Embraer S.A.): Amendment 39-22789; Docket No. FAA-2024-0772; Project Identifier MCAI-2023-01203-T. (a) Effective Date This airworthiness directive (AD) is effective September 25, 2024. (b) Affected ADs None. (c) Applicability This AD applies to Embraer S.A. (Type Certificate previously held by Yaborã Indústria Aeronáutica S.A.) Model ERJ 170-100 LR, -100 SE, -100 STD, and -100 SU airplanes, and Model ERJ 170-200 LL, -200 LR, -200 STD, and -200 SU airplanes, certificated in any category, as identified in Agência Nacional de Aviação Civil (ANAC) AD 2023-11-01, effective November 21, 2023 (ANAC AD 2023-11-01). (d) Subject Air Transport Association (ATA) of America Code 36, Pneumatic System. (e) Unsafe Condition This AD was prompted by a manufacturing quality escape concerning some overheat detection system (ODS) sensing elements. 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. (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 2023-11-01. (h) Exceptions to ANAC AD 2023-11-01 (1) Where ANAC AD 2023-11-01 refers to its effective date, this AD requires using the effective date of this AD. (2) Where paragraphs (b)(1), (c)(1), (d)(1), (e)(1), (f)(1), and (g)(1), of ANAC AD 2023-11-01 specify to inspect ODS sensing elements at various locations, this AD requires adding "in accordance with Embraer Service Bulletin 170-36-0027, revision 04, dated September 5, 2023; or later revisions approved by ANAC." (3) Where paragraphs (b) through (h) of ANAC AD 2023-11-01 specify on-condition actions based on the results of the ODS sensing element inspections required by paragraphs (b)(1), (c)(1), (d)(1), (e)(1), (f)(1), and(g)(1) of ANAC AD 2023-11-01, this AD requires performing all applicable on-condition actions before further flight after each inspection. (4) This AD does not adopt paragraph (k) of ANAC AD 2023-11-01. (i) Parts Returned to Supplier Where the service information referenced in ANAC AD 2023-11-01 specifies to send removed sensing elements to the supplier, this AD does not include that requirement. (j) Additional AD Provisions The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, International Validation 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 International Validation Branch, mail it to the address identified in paragraph (k) of this AD or email to: 9-ANM-Seattle-ACO-AMOC-Requests@faa.gov. If mailing information, also submit information by email. 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, International Validation 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 (j)(2) of this AD, if any service information referenced in ANAC AD 2023-11-01 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.
