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: a. Removing Airworthiness Directive 2019-25-16, Amendment 39-21015 (85 FR 453, January 6, 2020); and b. Adding the following new airworthiness directive: 2022-25-07 Embraer S.A. (Type Certificate Previously Held by Yaborã Indústria Aeronáutica S.A.; Embraer S.A.): Amendment 39-22263; Docket No. FAA-2022-0979; Project Identifier MCAI-2022-00171-T. (a) Effective Date This airworthiness directive (AD) is effective January 23, 2023. (b) Affected ADs This AD replaces AD 2019-25-16, Amendment 39-21015 (85 FR 453, January 6, 2020) (AD 2019-25-16). (c) Applicability This AD applies to all 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. (d) Subject Air Transport Association (ATA) of America Code 05, Time Limits/Maintenance Checks; 27, Flight controls; 28, Fuel; 52, Doors; 53, Fuselage; 54, Nacelles/pylons; 55, Stabilizers; 57, Wings; 71, Powerplant; and 78, Exhaust. (e) Unsafe Condition This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. The FAA is issuing this AD to address fatigue cracking of various principal structural elements (PSEs); such cracking could result in reduced structural integrity of the airplane. The FAA is also issuing this AD to address safety significant latent failures; such failures, in combination with one or more other specified failures or events, could result in a hazardous or catastrophic failure condition of avionics, hydraulic systems, fire detection systems, fuel systems, or other critical systems. Furthermore, the FAA is issuing this AD to address potential ignition sources inside fuel tanks caused by latent failures, alterations, repairs, or maintenance actions; such failures, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Retained Revision of the Existing Maintenance or Inspection Program, With No Changes This paragraph restates the requirements of paragraph (i) of AD 2019-25-16, with no changes. For Model ERJ 170-100 LR, -100 STD, -100 SE, and -100 SU airplanes; and Model ERJ 170-200 LR, -200 SU, -200 STD, and -200LL airplanes; manufacturer serial numbers 17000002, 17000004 through 17000013 inclusive, and 17000015 through 17000761 inclusive: Within 90 days after February 10, 2020 (the effective date of AD 2019-25-16), revise the existing maintenance or inspection program, as applicable, to incorporate the information specified in Part 1-Certification Maintenance Requirements, Part 2-Airworthiness Limitation Inspections (ALI)-Structures, Part 3-Fuel System Limitation Items, and Part 4-Life Limited Items; and EMBRAER Temporary Revision (TR) 14-1, dated November 13, 2018, to part 4-Life Limited Items; of Appendix A of the EMBRAER 170/175 MRBR, MRB-1621, Revision 14, dated September 27, 2018 (EMBRAER 170/175 MRB-1621, Revision 14). The initial compliance time for doing the tasks is at the later of the times specified in paragraphs (g)(1) and (2) of this AD. (1) Within the applicable times specified in EMBRAER 170/175 MRB-1621, Revision 14. For the purposes of this AD, the initial compliance times (identified as "Threshold" or "T" in EMBRAER 170/175 MRB-1621, Revision 14) are expressed in "total flight cycles" or "total flight hours," as applicable. (2) Within 90 days or 600 flight cycles after February 10, 2020 (the effective date of AD 2019-25-16), whichever occurs later. (h) Retained Restrictions on Alternative Actions, Intervals, and CDCCLs, With No Changes This paragraph restates the requirements of paragraph (j) of AD 2019-25-16, with no changes. 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 (l)(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 2022-02-01, effective February 9, 2022 (ANAC AD 2022-02-01). Accomplishing the revision of the existing maintenance or inspection program required by this paragraph terminates the requirements for Part 2-Airworthiness Limitation Inspections (ALI)-Structures specified in paragraph (g) of this AD only. (j) Exceptions to ANAC AD 2022-02-01 (1) Where ANAC AD 2022-02-01 refers to its effective date, this AD requires using the effective date of this AD. (2) The "Alternative method of compliance (AMOC)" section of ANAC AD 2022-02-01 does not apply to this AD. (3) Where paragraph (b)(1) of ANAC AD 2022-02-01 specifies incorporating all airworthiness limitations in Part 2 of the service information specified in paragraph (b)(1) of ANAC AD 2022-02-01, for this AD, do not incorporate the threshold and interval for maintenance review board report (MRBR) task number 57-30-002-0002, "Enhanced Wingtip to Wing Spar Attachments-Internal." Note 1 to paragraph (j)(3): AD 2022-11-51, Amendment 39-22074 (87 FR 33623, June 3, 2022) (AD 2022-11-51), requires, among other actions, incorporating alternate thresholds and intervals for MRBR task number 57-30-002-0002. The airplanes affected by MRBR task number 57-30-002-0002 are identified in paragraph (c) of AD 2022-11-51. (k) New Provisions for Alternative Actions and Intervals After the existing maintenance or inspection program has been revised as required by paragraph (i) of this AD, no alternative actions ( e.g., inspections), intervals, and CDCCLs are allowed unless they are approved as specified in paragraph (f) of ANAC AD 2022-02-01. (l) Additional FAA AD Provisions The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, Large Aircraft Section, 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 Large Aircraft Section, International Validation Branch, send it to the attention of the person identified in paragraph (m) of this AD. Information may be emailed to: 9-AVS-AIR-730-AMOC@faa.gov . (i) Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the responsible Flight Standards Office. (ii) AMOCs approved previously for AD 2019-25-16 are approved as AMOCs for the corresponding provisions of paragraph (g) of this AD. (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, Large Aircraft Section, 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 (l)(2) of this AD, if any service information referenced in ANAC AD 2022-02-01 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.
