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\n2021-07-13 Pacific Scientific Company: Amendment 39-21490; Docket No. FAA-2013-0752; Product Identifier 2009-SW-44-AD. \n\n(a) Applicability \n\n\n\tThis airworthiness directive (AD) applies to Pacific Scientific Company rotary buckle assembly (buckle), part numbers (P/Ns) 1111430 and 1111475, all dash numbers. These buckles may be installed on but not limited to Bombardier Inc., Learjet Inc., Mitsubishi Heavy Industries, Ltd., Textron Aviation, Inc. (Type Certificate (TC) previously held by Cessna Aircraft Company), and Viking Air Limited (TC previously held byde Havilland, Inc.) model airplanes and Airbus Helicopters (TC previously held by Eurocopter France) model helicopters, certificated in any category. \n\n\n\tNote 1 to paragraph (a): The rotary buckle may be included as a component of a different part-numbered restraint system assembly. Pacific Scientific Service Bulletin SB 25-1111432, dated May 22, 2007 (SB 25-1111432), Appendix 1, includes a list of these restraint system P/Ns. \n\n(b) Unsafe Condition \n\n\n\tThis AD defines the unsafe condition as a cracked rotary buckle handle, which could prevent a strap from releasing as intended when the buckle is rotated. \n\n(c) Effective Date \n\n\n\tThis AD becomes effective May 11, 2021. \n\n(d) Compliance \n\n\n\tYou are responsible for performing each action required by this AD within the specified compliance time unless it has already been accomplished prior to that time. \n\n(e) Required Actions \n\n\n\t(1) Within 6 months, inspect the buckle handle for a crack.

If the handle vane thickness is 0.125 inch or greater, before further flight, remove the buckle from service and replace it with an airworthy buckle. \n\t(3) As of the effective date of this AD, do not install a buckle or a restraint system with a buckle, P/N 1111430 or 1111475, all dash numbers, with a handle vane thickness of 0.125 inch or greater on any airplane or helicopter. \n\n(f) Alternative Methods of Compliance (AMOCs) \n\n\n\t(1) The Manager, International Validation Branch, FAA, may approve AMOCs for this AD.
