14 CFR Part 39

[Docket No. FAA-2025-0016; Project Identifier MCAI-2023-01047-T; 
Amendment 39-23025; AD 2025-09-04]

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 
address for Docket Operations is U.S. Department of Transportation,

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.

Material Incorporated by Reference Under 1 CFR Part 51

    The FAA reviewed the following Bombardier documents:
     Part 2, ``Airworthiness Limitations,'' of Bombardier 
Global Express Time Limits/Maintenance Checks (TLMC), Publication No. 
BD-700 TLMC, Revision 35, dated December 19, 2023. (For obtaining this 
part of Bombardier Global Express TLMC, Publication No. BD-700 TLMC, 
use Document Identification No. GL 700 TLMC.)
     Part 2, ``Airworthiness Limitations,'' of Bombardier 
Global Express XRS TLMC, Publication No. BD-700 XRS TLMC, Revision 22, 
dated December 19, 2023. (For obtaining this part of Bombardier Global 
Express XRS TLMC, Publication No. BD-700 XRS TLMC, use Document 
Identification No. GL XRS TLMC.)
     Part 2, ``Airworthiness Limitations,'' of Bombardier 
Global 6000 TLMC, Publication No. GL 6000 TLMC, Revision 16, dated 
December 19, 2023.
     Part 2, ``Airworthiness Limitations,'' of Bombardier 
Global 6500 TLMC, Publication No. GL 6500 TLMC, Revision 5, dated 
December 19, 2023.
     Part 2, ``Airworthiness Limitations,'' of Bombardier 
Global 5000 TLMC, Publication No. BD-700 TLMC, Revision 26, dated 
December 19, 2023. (For obtaining this part of Bombardier Global 5000 
TLMC, Publication No. BD-700 TLMC, use Document Identification No. GL 
5000 TLMC.)
     Part 2, ``Airworthiness Limitations,'' of Bombardier 
Global 5500 TLMC, Publication No. GL 5500 TLMC, Revision 5, dated 
December 19, 2023.
     Part 2, ``Airworthiness Limitations,'' of Bombardier 
Global 5000 Featuring Global Vision Flight Deck TLMC, Publication No. 
GL 5000 GVFD TLMC, Revision 16, dated December 19, 2023.
    This material specifies new or more restrictive airworthiness 
limitations for safe life limits (for certain main landing gear and 
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.

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

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
