Airworthiness Directive · Amendment 39-23254 · Autopilot main servo
Embraer S.A. Airplanes
This AD applies to Embraer S.A. Model EMB-505 airplanes, serial numbers 50500004 through 50500012, 50500014, 50500016 through 50500665, and 50500667 through 50500779, certificated in any category.
The FAA is superseding Airworthiness Directive (AD) 2023-22- 11, which applied to certain Embraer S.A. (Embraer) Model EMB-505 airplanes. AD 2023-22-11 required repetitively replacing the clutch retaining bolt and washer of the aileron autopilot servo mount. Since the FAA issued AD 2023-22-11, the FAA has determined that the applicability should include certain Model EMB-505 airplanes and, for certain airplanes, an additional requirement is necessary for the initial replacement of the retaining bolt and washer. This AD incorporates these additional airplanes into the applicability, adds the additional requirement, and also provides an optional terminating action for the repetitive retaining bolt and washer replacement. 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, Agência Nacional de Aviação Civil (ANAC) AD 2023-02-01R3, effective October 25, 2024 (ANAC AD 2023-02-01R3).
Note 1 to paragraph (g): TASK 22-11-03-960-801-A of Embraer Phenom 300 AMM 4610 Part II MPP, Revision 65, dated November 8, 2024, contains procedures for the replacement of the aileron autopilot servo mount clutch-retaining bolt and washer.
(1) Where ANAC AD 2023-02-01R3 refers to February 6, 2023, the effective date of ANAC AD 2023-02-01, this AD requires using December 26, 2023, the effective date of AD 2023-22-11.
(2) Where ANAC AD 2023-02-01R3 refers to its effective date, this AD requires using the effective date of this AD.
(3) Where ANAC AD 2023-02-01R3 requires replacing a part with a new part, for the purposes of this AD, a new part means a part that has accumulated zero flight hours.
(4) Where the “NOTE” to Table 01 in ANAC AD 2023-02-01R3 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 replacing that text with “comply with the most restrictive criteria for each applicability range (in months and flight hours) in Table 01 of ANAC AD 2023-02-01R3”.
(5) This AD does not adopt paragraph (e) of ANAC AD 2023-02-01R3.
Although the service material referenced in ANAC AD 2023-02-01R3 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.
