Airworthiness Directive · Amendment 39-22743 · Equipment/furnishings
Airbus Canada Limited Partnership (Type Certificate Previously Held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Airplanes
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).
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A11 airplanes. 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. This AD requires relocation and replacement of the existing PLB with a new PLB part number at the left-side forward wardrobe assembly, as specified in a Transport Canada AD, which is incorporated by reference. This AD also prohibits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products.
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.
Where Transport Canada AD CF-2023-57 refers to its effective date, this AD requires using the effective date of this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
