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: 2024-11-02 Bombardier, Inc.: Amendment 39-22763; Docket No. FAA-2023-2242; Project Identifier MCAI-2023-00704-T. (a) Effective Date This airworthiness directive (AD) is effective August 26, 2024. (b) Affected ADs None. (c) Applicability This AD applies to Bombardier, Inc., Model BD-100-1A10 airplanes, certificated in any category, having serial numbers (S/Ns) 20003 through 20500 inclusive, and 20501 through 20959 inclusive. (d) Subject Air Transport Association (ATA) of America Code 05, Time Limits/Maintenance Checks; 27, Stabilizer. (e) Reason This AD was prompted by a determination that new or more restrictive maintenance tasks are necessary. The FAA is issuing this AD to address failure or degradation of the horizontal stabilizer trim actuator (HSTA) and motor brake assembly. The unsafe condition, if not addressed, could result in loss of control of 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 in the tasks specified in figure 1 or 2 to paragraph (g) of this AD, as applicable. The initial compliance time for doing the tasks is at the time specified in the applicable temporary revision (TR) or time limit/maintenance check (TLMC) document specified in figures 1 and 2 to paragraph (g) of this AD, or within 60 days after the effective date of this AD, whichever occurs later. When the information in the applicable TR has been incorporated into the general revision of that Bombardier TLMC, the maintenance or inspection program may be revised using the information in the general revision. Figure 1 to Paragraph (g)-Tasks for Model BD-100-1A10 Airplanes Having S/Ns 20003 Through 20500 ER22JY24.200 Note 1 to Figure 1 to paragraph (g): The section number in the footer on certain pages of the TLMC sections is incomplete ( i.e., "05-10-2" instead of "05-10-20" and "05-10-4" instead of "05-10-40"). Note 2 to Figure 1 to paragraph (g): The asterisk (or "one star") or double asterisk ("two star") with the last three digits of the task numbers listed in figures 1 and 2 to paragraph (g) of this AD indicates that the task is an airworthiness limitation task. Figure 2 to Paragraph (g)-Tasks for Model BD-100-1A10 Airplanes Having S/Ns 20501 Through 20959 ER22JY24.201 (h) No Alternative Actions, or Intervals After the existing maintenance or inspection program has been revised as required by paragraph (g) of this AD, no alternative actions ( e.g., inspections) or intervals may be used unless the actions and intervals are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (i)(1) of this AD. (i) Other FAA 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.
