The FAA amends § 39.13 by adding the following new airworthiness directive: 2023-23-10 Embraer S.A.

The FAA is issuing this AD to address wear on the wing hinge bearing assembly of the aileron surfaces that could lead to excessive backlash. The unsafe condition, if not addressed, could result in a limit cycle oscillation phenomenon exposing the surrounding structure and systems to unacceptable vibration levels and reducing the airplane controllability. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Requirements 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).
