Airworthiness Directive · Amendment 39-22822 · Windows
Embraer S.A. Airplanes
This AD applies to Embraer S.A. Model EMB-550 and EMB-545 airplanes, certificated in any category, as identified in Agência Nacional de Aviação Civil (ANAC) AD 2020-04-01R02, effective November 2, 2023 (ANAC AD 2020-04-01R02).
The FAA is superseding Airworthiness Directive (AD) 2020-25- 07, which applied to certain Embraer S.A. Model EMB-550 and EMB-545 airplanes. AD 2020-25-07 required repetitive inspections of the flight deck side windows for any cracking or delamination, corrective action if necessary, and eventual replacement of the windows. Since the FAA issued AD 2020-25-07, additional part numbers were added to the installation prohibition list. This AD continues to require the actions in AD 2020-25-07, expands the list of affected parts, and prohibits the installation of affected parts, 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 2020-04-01R02.
(1) Where ANAC AD 2020-04-01R02 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where paragraph (b)(1) of ANAC AD 2020-04-01R02 refers to April 17, 2020 (the effective date of the original issue of ANAC AD 2020-04-01), this AD requires using January 21, 2021 (the effective date of AD 2020-25-07).
(3) Where paragraph (b)(1)(iii) of ANAC AD 2020-04-01R02 specifies “In case of no crack, delamination, or any other damage, no action is required at this time,” this AD requires replacing that text with “in the case of no findings specified in paragraphs (b)(1)(i) and (ii) of ANAC AD 2020-04-01R02, no further action is required by this AD until the next inspection interval.”
(4) Where paragraph (b)(2) of ANAC AD 2020-04-01R02 refers to the compliance time of the repetitive inspections, “at each 750 Flight Hours (FH),” this AD requires replacing that text with “at intervals not to exceed 750 flight hours.”
(5) Where paragraph (c) of ANAC AD 2020-04-01R02 refers to the compliance time for the replacement of the flight deck side windows as, “before the airplane logs 3,400 Flight Cycles Since New (FCSN),” this AD requires replacing that text with “before the airplane logs 3,400 FCSN, or within 50 flight cycles after the effective date of this AD, whichever occurs later.”
(6) Replacement of the flight deck side windows as specified in paragraph (c) of ANAC AD 2020-04-01R02 terminates the repetitive inspections for the flight deck side windows specified in paragraph (b)(2) of ANAC AD 2020-04-01R02.
(7) This AD does not adopt paragraph (e) of ANAC AD 2020-04-01R02.
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 (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.
