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: 2023-12-04 Pilatus Aircraft Ltd.: Amendment 39-22462; Docket No. FAA-2023-0926; Project Identifier MCAI-2022-01583-A. (a) Effective Date This airworthiness directive (AD) is effective August 7, 2023. (b) Affected ADs None. (c) Applicability This AD applies to Pilatus Aircraft Ltd. Model PC-24 airplanes, serial numbers 231 through 252 inclusive and serial numbers 254 and 255, certificated in any category. (d) Subject Joint Aircraft System Component (JASC) Codes 3497, Navigation System Wiring; and 3442, Weather Radar System. (e) Unsafe Condition This AD was prompted by a report that an incorrect wiring arrangement was detected around the weather radar system. The FAA is issuing this AD to address an incorrect wiring arrangement around the weather radar system. The unsafe condition, if not addressed, could, in the case of a lightning strike, lead to the partial loss of flight and navigation data displayed to the pilot or pilots, possibly resulting in increased flight crew workload and a consequent reduction of safety margins. (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, European Union Aviation Safety Agency (EASA) AD 2022-0249, dated December 14, 2022 (EASA AD 2022-0249).

(2) Where the service information referenced in paragraph (1) of EASA AD 2022-0249 specifies removing and discarding parts, this AD requires removing those parts from service. (3) This AD does not adopt the "Remarks" paragraph of EASA AD 2022-0249. (i) No Reporting Requirement Although the service information referenced in EASA AD 2022-0249 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 § 39.19.
