Airworthiness Directive · Amendment 39-22266 · Nacelles/pylons
Embraer S.A. (Type Certificate Previously Held by Yaborã Indústria Aeronáutica S.A.; Embraer S.A.) Airplanes
This AD applies to Embraer S.A. (Type Certificate previously held by Yaborã Indústria Aeronáutica S.A.; Embraer S.A.) Model ERJ 190-300 and -400 airplanes, certificated in any category, as identified in Agência Nacional de Aviação Civil (ANAC) AD 2022-07-01, effective July 11, 2022 (ANAC AD 2022-07-01).
The FAA is adopting a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 190-300 and -400 airplanes. This AD was prompted by reports of friction marks on the engine fire extinguishing system tube, in the region of the aft fairing of the left-hand (LH) pylon. This AD requires rework of the retainer of the LH pylon access panel, inspection and replacement, as applicable, of the LH engine fire extinguishing system tube, and installation of a support, as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
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 2022-07-01.
(1) Where ANAC AD 2022-07-01 refers to its effective date, this AD requires using the effective date of this AD.
(2) Paragraph (d) “Alternative methods of compliance (AMOCs)” of ANAC AD 2022-07-01 is not adopted by this AD.
(3) ANAC AD 2022-07-01 does not specify a compliance time for the action specified in paragraph (b)(2)(i) of ANAC AD 2022-07-01. For this AD, after accomplishing the inspection required by paragraph (b)(2) of ANAC AD 2022-07-01, the action required by paragraph (b)(2)(i) of ANAC AD 2022-07-01 must be done before further flight, if there is any sign of friction marks on the tube.
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 (j) 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 required by paragraph (i)(2) of this AD, if any service information referenced in MCAI AD 2022-07-01 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.
