The FAA amends § 39.13 by adding the following new airworthiness directive: 2023-03-19 Embraer S.A. (Type Certificate Previously Held by Yaborã Indústria Aeronáutica S.A.; Embraer S.A.): Amendment 39-22344; Docket No. FAA-2022-1243; Project Identifier MCAI-2022-00674-T. (a) Effective Date This airworthiness directive (AD) is effective April 7, 2023. (b) Affected ADs This AD affects AD 2020-05-22, Amendment 39-19872 (85 FR 15936, March 20, 2022) (AD 2020-05-22). (c) Applicability This AD applies to Embraer S.A. (Type Certificate previously held by Yaborã Indústria Aeronáutica S.A.; Embraer S.A.) Model ERJ 170-100 LR, -100 STD, -100 SE, and -100 SU airplanes; and Model ERJ 170-200 LR, -200 SU, -200 STD, and -200 LL airplanes, certificated in any category, as identified in Agência Nacional de Aviação Civil (ANAC) AD 2022-05-03, effective May 25, 2022 (ANAC AD 2022-05-03). (d) Subject Air Transport Association (ATA) of America Code 31, Instruments. (e) Unsafe Condition This AD was prompted by a report of uncommanded setting of the barometric reference in both primary flight displays due to the architecture of data communication of the Control I/O modules, which interconnect the display controllers to the air data system. The FAA is issuing this AD to address this condition, which could interfere with the decisions taken by the flightcrew during critical phases of flight, and possibly result in reduced controllability 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 2022-05-03. (h) Exceptions to ANAC AD 2022-05-03 (1) Where ANAC AD 2022-05-03 refers to its effective date, this AD requires using the effective date of this AD. (2) Paragraph (c)(1) of ANAC AD 2022-05-03 does not apply to this AD. (3) Where paragraph (d) of ANAC AD 2022-05-03 specifies you must use certain service information for software installation, this AD specifies to use that service information as applicable, except as provided in paragraphs (a)(1) and (2) of ANAC AD 2022-05-03. (i) Terminating Action for AD 2020-05-22 Accomplishing the actions required by this AD on an airplane terminates all requirements of AD 2020-05-22 for that airplane only. (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 International Validation Branch, send it to the attention of the person identified in paragraph (k) of this AD. Information may be emailed to: 9-AVS-AIR-730-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, 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 specified by paragraph (j)(2) of this AD: if any service information contains steps that are labeled as RC, the provisions of paragraphs (j)(3)(i) and (ii) of this AD apply. (i) The steps labeled as RC, including substeps under an RC step and any figures identified in an RC step, must be done to comply with the AD. If a step or substep is labeled "RC Exempt," then the RC requirement is removed from that step or substep. An AMOC is required for any deviations to RC steps, including substeps and identified figures. (ii) Steps not labeled 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 RC steps, including substeps and identified figures, can still be done as specified, and the airplane can be put back in an airworthy condition.
