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 adding the following new airworthiness directive: 2023-21-04 Embraer S.A.: Amendment 39-22576; Docket No. FAA-2023-1708; Project Identifier MCAI-2023-00554-A. (a) Effective Date This airworthiness directive (AD) is effective December 11, 2023. (b) Affected ADs None. (c) Applicability This AD applies to Embraer S.A. Model EMB-505 airplanes, as identified in paragraph (a) of Agência Nacional de Aviação Civil (ANAC) AD 2023-04-01, effective April 4, 2023 (ANAC AD 2023-04-01), certificated in any category. (d) Subject Joint Aircraft System Component (JASC) Code 3100, Indicating/recording system. (e) Unsafe Condition This AD was prompted by occurrences of an uncommanded change in the setting of the barometric pressure in both primary flight displays (PFDs). The FAA is issuing this AD to address the uncommanded change in the setting of the barometric pressure in both PFDs. The unsafe condition, if not addressed, could result in altitude mismanagement or spatial disorientation of the flight crew, with consequent deviation from the intended altitude and loss of control of the airplane, risk of air collision due to inadequate air traffic separation, or risk of controlled flight into terrain. (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, ANAC AD 2023-04-01.

(2) This AD does not adopt paragraphs (c), (d), and (e) of ANAC AD 2023-04-01. (i) No Reporting Required Although the service information referenced in ANAC AD 2023-04-01 specifies to submit certain information to the manufacturer, this AD does not include that requirement. (j) 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.
