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: 2024-09-01 Airbus Canada Limited Partnership (Type Certificate Previously Held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.): Amendment 39-22743; Docket No. FAA-2024-1292; Project Identifier MCAI-2023-00908-T. (a) Effective Date This airworthiness directive (AD) is effective July 2, 2024. (b) Affected ADs None. (c) Applicability This AD applies to Airbus Canada Limited Partnership (type certificate previously held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Model BD-500-1A11 airplanes, certificated in any category, as identified in Transport Canada AD CF-2023-57, dated July 25, 2023 (Transport Canada AD CF-2023-57). (d) Subject Air Transport Association (ATA) of America Code 25, Equipment/Furnishings. (e) Unsafe Condition This AD was prompted by a design review that found that the heat generated by a thermal runaway event, caused by the lithium batteries of the wardrobe personal locator beacon (PLB) would not be sufficiently mitigated by the PLB design to prevent any adverse effect on the two portable oxygen cylinder assemblies located near the PLB installation. The FAA is issuing this AD to prevent a lithium battery fire at the left-side forward wardrobe assembly. The unsafe condition, if not addressed, could result in fire and smoke in the cabin leading to reduced ability of the flightcrew to maintain the safe flight and landing of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) PLB Relocation and Replacement Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, Transport Canada AD CF-2023-57. (h) Exception To Transport Canada AD CF-2023-57 Where Transport Canada AD CF-2023-57 refers to its effective date, this AD requires using the effective date of this AD. (i) Parts Installation Prohibition As of the effective date of this AD, no person may install a PLB part number 500-12Y on any airplane.
