Airworthiness Directive · Amendment 39-22612 · Flight controls
Embraer S.A. (Type Certificate Previously Held by Yaborã Indústria Aeronáutica S.A.; Embraer S.A.) Airplanes
Superseded. A later AD replaced this one: AD 2024-25-04. Comply with the one in force.
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 airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Embraer S.A. Model ERJ 190-300 airplanes. This AD was prompted by a report of unexpected wear on the wing hinge bearing assembly of the aileron surfaces found during the functional test of the aileron control system backlash. This AD requires repetitive inspections of the press-fitted bushings of the wing ailerons for migration and broken sealant, measurements of the distance between the aileron surfaces and hinge fittings, functional checks of the backlash of the wing aileron control system, and all applicable related investigative and corrective actions, 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 2023-06-01, effective June 16, 2023 (ANAC AD 2023-06-01).
(1) Where ANAC AD 2023-06-01 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where paragraphs (b)(2)(i) and (b)(3)(i) of ANAC AD 2023-06-01 specify “before the next flight, accomplish the paragraph (c) of this AD after to accomplish the paragraph (b)(4) of this AD” as corrective actions for certain conditions, this AD requires replacing those words with “before the next flight, accomplish paragraph (c) of this AD after accomplishing paragraph (b)(4) of this AD.”
(3) Where paragraph (b)(3) of ANAC AD 2023-06-01 specifies to “measure de distances,” this AD requires replacing those words with “measure the distances.”
(4) All applicable related investigative and corrective actions specified in paragraphs (b)(4)(iii) and (b)(4)(iii)(a) of ANAC AD 2023-06-01 must be done before the next flight after the functional check of the left-hand (LH) and right-hand (RH) wing aileron control system.
(5) All applicable related investigative actions specified in paragraph (c)(4)(ii) of ANAC AD 2023-06-01 must be done before the next flight after the detailed inspection on the LH and RH removed aileron surface, as applicable.
(6) Where paragraph (d) of ANAC AD 2023-06-01 specifies to repeat the inspections “at each 5,500 FH,” this AD requires replacing those words with “at intervals not to exceed 5,500 FH.”
(7) This AD does not adopt paragraph (e) of ANAC AD 2023-06-01.
(8) Although the service information specified in ANAC AD 2023-06-01 specifies returning certain parts the manufacturer, this AD does not include that requirement.
Although the service information in ANAC AD 2023-05-02 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
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.

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.
