Airworthiness Directive · Amendment 39-22595 · Autopilot main servo
Embraer S.A. Airplanes
Superseded. A later AD replaced this one: AD 2026-03-05. Comply with the one in force.
This AD applies to Embraer S.A. Model EMB-505 airplanes, as identified in Agência Nacional de Aviação Civil (ANAC) AD 2023-02-01R1, effective March 14, 2023 (ANAC AD 2023-02-01R1), certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for certain Embraer S.A. (Embraer) Model EMB-505 airplanes. This AD was prompted by an occurrence of corrosion on the clutch retaining bolt of the aileron autopilot servo mount. This AD requires repetitively replacing the clutch retaining bolt and washer of the aileron autopilot servo mount, 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 paragraphs (h) and (i) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, ANAC AD 2023-02-01R1.
(1) Where ANAC AD 2023-02-01R1 refers to February 6, 2023, the effective date of ANAC AD 2023-02-01, this AD requires using the effective date of this AD.
(2) Where ANAC AD 2023-02-01R1 requires replacing a part with a new part, for the purposes of this AD, “new” means zero flight hours.
(3) Where the “NOTE” to Table 01 in ANAC AD 2023-02-01R1 specifies “If the airplane operation age and/or the flight hours criteria change before the SB accomplishment, the most restrictive criteria must be obeyed,” this AD requires complying with the most restrictive criteria for each applicability range (in months and flight hours) in Table 01 of ANAC AD 2023-02-01R1.
(4) This AD does not adopt paragraph (d) of ANAC AD 2023-02-01R1.
Although the service information referenced in ANAC AD 2023-02-01R1 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
