Airworthiness Directive · Amendment 39-22437 · Flight controls
Embraer S.A. (Type Certificate Previously Held by Yaborã Indústria Aeronáutica S.A.; Embraer S.A.) Airplanes
This AD applies to Embraer S.A Model ERJ 190-300, and 190-400 airplanes, certificated in any category, as identified in Agência Nacional de Aviação Civil (ANAC) 2022-09-01, effective September 7, 2022 (ANAC AD 2022-09-01).
The FAA is adopting a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 190-300 and ERJ 190-400 airplanes. This AD was prompted by the excessive operation of certain elevator and rudder surfaces during manufacturing, causing damage and accelerating wear of internal parts of the power control units (PCUs). This AD requires replacement of the left-hand (LH) and right-hand (RH) elevator PCUs and lower and upper rudder PCUs, 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 2022-09-01.
(1) Where ANAC AD 2022-09-01 refers to its effective date, this AD requires using the effective date of this AD.
(2) The “Alternative methods of compliance (AMOC)” section of ANAC AD 2022-09-01 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.
