    Airworthiness Directives; Bombardier Inc. Airplanes

    AGENCY: Federal Aviation Administration (FAA), DOT.

    ACTION: Final rule.

    -----------------------------------------------------------------------

    SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
    certain Bombardier Inc. Model BD-700-1A10 and BD-700-1A11 airplanes.
    This AD was prompted by a determination that new or more restrictive
    airworthiness limitations are necessary. This AD requires revising the
    existing maintenance or inspection program, as applicable, to
    incorporate new or more restrictive airworthiness limitations. The FAA
    is issuing this AD to address the unsafe condition on these products.

    DATES: This AD is effective June 6, 2025.
        The Director of the Federal Register approved the incorporation by
    reference of certain publications listed in this AD as of June 6, 2025.

    ADDRESSES:
        AD Docket: You may examine the AD docket at regulations.gov under
    Docket No. FAA-2025-0016; or in person at Docket Operations between 9
    a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD
    docket contains this final rule, the mandatory continuing airworthiness
    information (MCAI), any comments received, and other information. The

    SUPPLEMENTARY INFORMATION:

    Background

        The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
    CFR part 39 by adding an AD that would apply to certain Bombardier Inc.
    Model BD-700-1A10 and BD-700-1A11 airplanes. The NPRM was published in
    the Federal Register on February 4, 2025 (90 FR 8915). The NPRM was
    prompted by AD CF-2023-65, dated October 3, 2023, issued by Transport
    Canada, which is the aviation authority for Canada (also referred to as
    ``the MCAI''). The MCAI states that new or more restrictive
    airworthiness limitations have been developed.
        In the NPRM, the FAA proposed to require revising the existing
    maintenance or inspection program, as applicable, to incorporate new or
    more restrictive airworthiness limitations. 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.
        You may examine the MCAI in the AD docket at regulations.gov under
    Docket No. FAA-2025-0016.

    Discussion of Final Airworthiness Directive

    Comments

        The FAA received no comments on the NPRM or on the determination of
    the costs.

    Conclusion

        These products have been approved by the civil aviation authority
    of another country and are approved for operation in the United States.
    Pursuant to the FAA's bilateral agreement with this State of Design
    Authority, that authority has notified the FAA of the unsafe condition
    described in the MCAI referenced above. The FAA reviewed the relevant
    data, considered any comments received, and determined that air safety
    requires adopting this AD as proposed. Accordingly, the FAA is issuing
    this AD to address the unsafe condition on these products. Except for
    minor editorial changes, this AD is adopted as proposed in the NPRM.

    nose landing gear components) and certification maintenance
    requirements (for the shock strut axle and service door, pitch trim
    actuator, and nose landing gear shock-strut

    assembly to retraction-actuator main-fitting joint). These documents
    are distinct since they apply to different airplane models in different
    configurations. This material is reasonably available because the
    interested parties have access to it through their normal course of
    business or by the means identified in the ADDRESSES section.

    Costs of Compliance

        The FAA estimates that this AD affects 484 airplanes of U.S.
    registry. The FAA estimates the following costs to comply with this AD:
        The FAA has determined that revising the maintenance or inspection
    program takes an average of 90 work-hours per operator, although the
    agency recognizes that this number may vary from operator to operator.
    Since operators incorporate maintenance or inspection program changes
    for their affected fleet(s), the FAA has determined that a per-operator
    estimate is more accurate than a per-airplane estimate. Therefore, the
    agency estimates the average total cost per operator to be $7,650 (90
    work-hours x $85 per work-hour).

    Authority for This Rulemaking

        Title 49 of the United States Code specifies the FAA's authority to
    issue rules on aviation safety. Subtitle I, section 106, describes the
    authority of the FAA Administrator. Subtitle VII: Aviation Programs,
    describes in more detail the scope of the Agency's authority.
        The FAA is issuing this rulemaking under the authority described in
    Subtitle VII, Part A, Subpart III, Section 44701: General requirements.
    Under that section, Congress charges the FAA with promoting safe flight
    of civil aircraft in air commerce by prescribing regulations for
    practices, methods, and procedures the Administrator finds necessary
    for safety in air commerce. This regulation is within the scope of that
    authority because it addresses an unsafe condition that is likely to
    exist or develop on products identified in this rulemaking action.

    Regulatory Findings

        This AD will not have federalism implications under Executive Order
    13132. This AD will not have a substantial direct effect on the States,
    on the relationship between the national government and the States, or
    on the distribution of power and responsibilities among the various
    levels of government.
        For the reasons discussed above, I certify that this AD:
        (1) Is not a ``significant regulatory action'' under Executive
    Order 12866,
        (2) Will not affect intrastate aviation in Alaska, and
        (3) Will not have a significant economic impact, positive or
    negative, on a substantial number of small entities under the criteria
    of the Regulatory Flexibility Act.

    The Amendment

        Accordingly, under the authority delegated to me by the
    Administrator, the FAA amends 14 CFR part 39 as follows:

    1. The authority citation for part 39 continues to read as follows:

        Authority: 49 U.S.C. 106(g), 40113, 44701.

    Sec.  39.13  [Amended]

    2. The FAA amends Sec.  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.
