Adoption of the Amendment \n\n\n\tAccordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: \n\nPART 39--AIRWORTHINESS DIRECTIVES \n\n0 1. The authority citation for part 39 continues to read as follows: \n\n\n\tAuthority: 49 U.S.C. 106(g), 40113, 44701. \n\n\n\nSec. 39.13 (Amended) \n\n0 2. The FAA amends Sec. 39.13 by adding the following new airworthiness directive: \n\n2020-22-17 Pilatus Aircraft Ltd.: Amendment 39-21313; Docket No. FAA-2020-0719; Project Identifier 2019-CE-041-AD. \n\n(a) Effective Date \n\n\n\tThis airworthiness directive (AD) is effective December 14, 2020. \n\n(b) Affected ADs \n\n\n\tNone. \n\n(c) Applicability \n\n\n\tThis AD applies to Pilatus Aircraft Ltd. Model PC-24 airplanes, all serial numbers, certificated in any category, with a flexible saddle clamp part number (P/N) 946.33.22.004 installed between frame 34 and 36. \n\n(d) Subject \n\n\n\tJoint Aircraft System Component (JASC) Code 2800: Fuel.(e) Reason \n\n\n\tThis AD was prompted by an occurrence of movement of the aft fuel pipe within the coupling when system pressure was applied. This movement can cause damage to the O-rings, which could lead to a fuel leak and fuel contamination of the rear fuselage. The FAA is issuing this AD to prevent a fuel fire or fuel vapor explosion with consequent loss of airplane control. \n\n(f) Actions and Compliance \n\n\n\tUnless already done, do the following actions in accordance with the applicable compliance times: \n\t(1) Within 3 months after the effective date of this AD, replace each flexible saddle clamp with a fixed saddle clamp with P/N 946.33.21.933, align the left-hand (LH) and right-hand (RH) motive- flow fuel pipes, and test the LH and RH motive-flow fuel pipe for leaks in accordance with the Accomplishment Instructions, sections 3.B and 3.C, of Pilatus PC-24 Service Bulletin No. 28-002, dated May 3, 2019. \n\t(2) As of the effective date of this AD, do not install a flexible saddle clamp with P/N 946.33.22.004 between frame 34 and 36 on any airplane. \n\n(g) Alternative Methods of Compliance (AMOCs) \n\n\n\tThe 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.
