Airworthiness Directive · Amendment 39-22516 · Navigation
Embraer S.A. (Type Certificate Previously Held by Yaborã Indústria Aeronáutica S.A.; Embraer S.A.) Airplanes
This AD applies to all 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.
The FAA is adopting a new airworthiness directive (AD) for all Embraer S.A. Model ERJ 190-300 and -400 airplanes. This AD was prompted by identification that, during simulations, analysis, and an in-service event of the airplane, a stall warning system activation (i.e., stick shaker) and angle of attack (AOA) limiter engagement may occur in certain vertical gust conditions with specific intensity and frequency. This AD requires revising the Limitations section of the existing airplane flight manual (AFM) to incorporate minimum operating speeds during flight at moderate or severe turbulence conditions, 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, Agência Nacional de Aviação Civil (ANAC) AD 2023-01-01, effective January 18, 2023 (ANAC AD 2023-01-01).
(1) Where ANAC AD 2023-01-01 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where paragraph (a) of ANAC AD 2023-01-01 specifies to revise certain information, replace the text “introduce the following”, with “incorporate the information in the following”.
(3) The “Alternative methods of compliance (AMOC)” section of ANAC AD 2023-01-01 does not apply to this AD.
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.
