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: 2025-09-04 Bombardier Inc.: Amendment 39-23025; Docket No. FAA-2025-0016; Project Identifier MCAI-2023-01047-T. (a) Effective Date This airworthiness directive (AD) is effective June 6, 2025. (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 (S/Ns) 9002 through 9879 inclusive, 9998, and 60001 through 60065 inclusive. (d) Subject Air Transport Association (ATA) of America Code 05, Time Limits/Maintenance Checks. (e) Unsafe Condition This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. The FAA is issuing this AD to address new or more restrictive airworthiness limitations. Failure to adhere to the specified airworthiness limitations could adversely affect the stability and controllability of the airplane on landing and could result in damage to the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Maintenance or Inspection Program Revision Within 60 days after the effective date of this AD, revise the existing maintenance or inspection program, as applicable, to incorporate the information specified in the tasks identified in table 1 to paragraph (g) of this AD, of Part 2, "Airworthiness Limitations," of the applicable time limits/maintenance checks (TLMC) manual identified in table 2 of this AD. The initial compliance time for doing the tasks is at the time specified in the applicable TLMC manual identified in table 2 to paragraph (g) of this AD, or within 60 days after the effective date of this AD, whichever occurs later, except as provided by paragraph (h) of this AD.
