2024-23-02: Landing Gear

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: 2024-23-02 Bombardier, Inc.: Amendment 39-22881; Docket No. FAA-2024-0228; Project Identifier MCAI-2022-00599-T. (a) Effective Date This airworthiness directive (AD) is effective January 15, 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, serial numbers 9002 through 9998 inclusive, and 60001 through 60046 inclusive. (d) Subject Air Transport Association (ATA) of America Code 05, Time Limits/Maintenance Checks; 32, Landing Gear. (e) Reason This AD was prompted by a determination that new or more restrictive airworthiness limitations for certain brake accumulators are necessary. The FAA is issuing this AD to address brake accumulators that could surpass a life limit and fail, resulting in loss of hydraulic pressure on the associated hydraulic system, which services the main and emergency/parking brakes on the main landing gear. The unsafe condition, if not addressed, could result in reduced or total loss of available braking and a possible runway excursion. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Maintenance or Inspection Program Revision Within 90 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 table 1 to paragraph (g) of this AD of Section 5-10-11, "Life Limits (Systems)," of Part 2, "Airworthiness Limitations," of the applicable Time Limits/Maintenance Checks (TLMC) Manual. The initial compliance time for doing the tasks is at the time specified in the tasks specified in table 1 to paragraph (g) of this AD, or within 90 days after the effective date of this AD, whichever occurs later.
