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: 2024-02-05 Bombardier, Inc.: Amendment 39-22669; Docket No. FAA-2023-1223; Project Identifier MCAI-2022-00982-T. (a) Effective Date This airworthiness directive (AD) is effective April 9, 2024. (b) Affected ADs None. (c) Applicability This AD applies to Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes, certificated in any category, having serial numbers 9002 through 9879 inclusive, 9998, and 60001 and subsequent. (d) Subject Air Transport Association (ATA) of America Code: 57, Wings. (e) Reason This AD was prompted by a determination that a certain nondestructive test (NDT) procedure associated with a certain airworthiness limitation for inspecting for cracks at the inboard, mid, and outboard flap metallic end ribs does not contain all of the necessary instructions. The FAA is issuing this AD to address undetected cracks. The unsafe condition, if not addressed, could result in structural failure of the flap, which could result in possible reduced structural integrity of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Maintenance Procedure Limitation As of 90 days after the effective date of this AD, revise the existing maintenance or inspection program, as applicable, to use procedure ET-57-51-009, "Special Detailed Inspection of the Inboard, Mid and Outboard Flap (Metallic) End Ribs", of Part 6-Eddy Current, of the applicable Bombardier NDT manual specified in paragraphs (g)(1) through (7) of this AD when performing airworthiness limitation task number 57-51-00-109.
