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 2023-12-17, Amendment 39-22475 (88 FR 42604, July 3, 2023); and b. Adding the following new airworthiness directive: 2024-08-07 Pilatus Aircraft Ltd.: Amendment 39-22740; Docket No. FAA-2024-0045; Project Identifier MCAI-2023-01088-A. (a) Effective Date This airworthiness directive (AD) is effective June 3, 2024. (b) Affected ADs This AD replaces AD 2023-12-17, Amendment 39-22475 (88 FR 42604, July 3, 2023) (AD 2023-12-17). (c) Applicability This AD applies to Pilatus Aircraft Ltd. Model PC-12, PC-12/45, PC-12/47, and PC-12/47E airplanes, all serial numbers, certificated in any category. (d) Subject Joint Aircraft System Component (JASC) Code 3211, Main Landing Gear Attach Section. (e) Unsafe Condition This AD was prompted by a revision to the airworthiness limitations section (ALS) of the existing aircraft maintenance manual (AMM) introducing new and more restrictive instructions and maintenance tasks as specified in the component limitations section, which include repetitive eddy current inspections for cracks in the main landing gear yoke fitting. The FAA is issuing this AD to address failure of certain parts, which could result in asymmetric main landing gear failure that could lead to loss of airplane control during take-off, landing, and taxiing operations. (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 2023-0184, dated October 19, 2023 (EASA AD 2023-0184).

(3) Where paragraph (3) of EASA AD 2023-0184 specifies "Within 12 months after the effective date of this AD, revise the AMP," replace that text with "Within 30 days after the effective date of this AD, revise the airworthiness limitations section of your existing airplane maintenance manual or instructions for continued airworthiness and your existing approved maintenance or inspection program, as applicable." (4) The initial compliance time for doing the tasks specified in paragraph (3) of EASA AD 2023-0184 is on or before the applicable "limitations" and "associated thresholds" as incorporated by the requirements of paragraph (3) of EASA AD 2023-0184 or within 30 days after the effective date of this AD, whichever occurs later. (5) This AD does not adopt the "Remarks" section of EASA AD 2023-0184. (i) Provisions for Alternative Actions and Intervals No alternative actions and associated thresholds and intervals, including life limits, are allowed for compliance with paragraph (g) of this AD unless they are approved as specified in the provisions of the "Ref. Publications" section of EASA AD 2023-0184.
