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\n((Page 57560)) \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\n2021-20-20 Pacific Aerospace Limited: Amendment 39-21758; Docket No. FAA-2021-0576; Project Identifier 2019-CE-008-AD. \n\n(a) Effective Date \n\n\n\tThis airworthiness directive (AD) is effective November 22, 2021. \n\n(b) Affected ADs \n\n\n\tNone. \n\n(c) Applicability \n\n\n\tThis AD applies to Pacific Aerospace Limited Model 750XL airplanes, serial numbers 177, 186 through 213, 220, 8001, and 8002, certificated in any category. \n\n\n\t(d) Subject \n\n\n\tJoint Aircraft System Component (JASC) Code 3600, Pneumatic System. \n\n(e) Unsafe ConditionThis AD was prompted by mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as failure of the installation of the wing leading edge tank fuel pickup assembly in a pre-stressed condition, which could cause cracks in the wing spar web or the fuel pickup assembly pipe. The FAA is issuing this AD to prevent cracks in the wing spar web and the fuel pickup pipe. This condition could result in reduced structural integrity of the wing spar or cause a fuel leak, which could result in an engine fire. \n\n(f) Compliance \n\n\n\tComply with this AD within the compliance times specified, unless already done. \n\n(g) Required Actions \n\n\n\tWithin 165 hours time-in-service after the effective date of this AD, inspect the angle of the support bracket on the wing leading edge tank fuel pickup assembly and, before further flight, take any necessary additional actions and corrective actions by following the Accomplishment Instructions in Pacific Aerospace Mandatory Service Bulletin PACSB/XL/109, Issue 1, dated January 16, 2019. \n\n(h) Alternative Methods of Compliance (AMOCs) \n\n\n\t(1) The Manager, International Validation Branch, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or local Flight Standards District Office, as appropriate.
