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: 2024-04-06 Airbus Canada Limited Partnership (Type Certificate Previously Held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.): Amendment 39-22685; Docket No. FAA-2023-1709; Project Identifier MCAI-2022-01642-T. (a) Effective Date This airworthiness directive (AD) is effective April 22, 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-500-1A10 and BD-500-1A11 airplanes, certificated in any category, as identified in Transport Canada AD CF-2022-70, dated December 21, 2022 (Transport Canada AD CF-2022-70). (d) Subject Air Transport Association (ATA) of America Code: 28, Fuel. (e) Unsafe Condition This AD was prompted by reports of mechanical wear damage on the motive flow fuel-feed tubes that were secured by bonding clamps and clamp blocks inside the collector tank. The FAA is issuing this AD to address mechanical wear damage on the motive flow fuel-feed tubes. Failure of the affected motive flow fuel-feed tubes and a subsequent failure of the gravity transfer system could lead to a fuel imbalance condition resulting in a reduction in airplane functional capabilities and increased crew workload. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Requirements 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-2022-70. (h) Exceptions to Transport Canada AD CF-2022-70 (1) Where Transport Canada AD CF-2022-70 refers to its effective date, this AD requires using the effective date of this AD. (2) Where Transport Canada AD CF-2022-70 specifies "hours air time", this AD requires replacing that text with "flight hours." (3) Where Part II of Transport Canada AD CF-2022-70 specifies "rectify as required," this AD requires replacing that text with "accomplish all corrective actions before further flight." (4) Where the service information referenced in Part II of Transport Canada AD CF-2022-70 specifies to do rework if there is no damage or paint damage only, operators may either do the rework or replace the fuel tubes as specified in the service information referenced in Part II of Transport Canada AD CF-2022-70. (i) No Reporting Requirement Although the service information referenced in Transport Canada AD CF-2022-70 specifies to submit certain information to the manufacturer, this AD does not include that requirement. (j) Additional AD Provisions The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The 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.
