The FAA's summary their words, unchanged

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.

1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. 2. The FAA amends § 39.13 by: a. Removing Airworthiness Directive AD 2023-22-11, Amendment 39-22595 (88 FR 80565, November 20, 2023); and b. Adding the following new airworthiness directive: 2026-03-05 Embraer S.A.: Amendment 39-23254; Docket No. FAA-2025-0478; Project Identifier MCAI-2024-00647-A. (a) Effective Date This airworthiness directive (AD) is effective March 31, 2026. (b) Affected ADs This AD replaces AD 2023-22-11, Amendment 39-22595 (88 FR 80565, November 20, 2023) (AD 2023-22-11). (c) Applicability 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. (d) Subject Joint Aircraft System Component (JASC) Code 2215, Autopilot Main Servo. (e) Unsafe Condition This AD was prompted by corrosion on the clutch retaining bolt of the aileron autopilot servo mount. The FAA is issuing this AD to address the unsafe condition. The unsafe condition, if not addressed, could result in failure of the clutch retaining bolt of the aileron autopilot servo mount, which could disengage the clutch from the drive pin and jam the aileron controls, which could result in reduced controllability of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Required Actions 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. (h) Exceptions to ANAC AD 2023-02-01R3 (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. (i) No Reporting Requirement 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. (j) Alternative Methods of Compliance (AMOCs) (1) 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.
