Background

    Transport Canada, which is the aviation authority for Canada, has 
issued Transport Canada AD CF-2023-65, dated October 3, 2023 (Transport 
Canada AD CF-2023-65) (also referred to after this as the MCAI), to 
correct an unsafe condition for certain Bombardier, Inc., Model BD-700-
1A10 and BD-700-1A11 airplanes. The MCAI states that new or more 
restrictive airworthiness limitations have been developed.
    The FAA is proposing 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.

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 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.

FAA's Determination

    This product has been approved by the aviation authority of another 
country and is approved for operation in the United States. Pursuant to 
the FAA's bilateral agreement with this State of Design Authority, the 
FAA has been notified of the unsafe condition described in the MCAI and 
material referenced above. The FAA is proposing this AD because the FAA 
evaluated all the relevant information and determined the unsafe 
condition described previously is likely to exist or develop on other 
products of the same type design.

Proposed Requirements of This NPRM

    This proposed AD would require revising the existing maintenance or 
inspection program, as applicable, to incorporate new or more 
restrictive airworthiness limitations.
    This proposed AD would require revisions to certain operator 
maintenance documents to include new actions (e.g., inspections). 
Compliance with these actions is required by 14 CFR 91.403(c). For 
airplanes that have been previously modified, altered, or repaired in 
the areas addressed by this proposed AD, the operator may not be able 
to accomplish the actions described in the revisions. In this 
situation, to comply with 14 CFR 91.403(c), the operator must request 
approval for an alternative method of compliance according to paragraph 
(j)(1) of this proposed AD.

Differences Between This Proposed AD and the MCAI

    Although the applicability of Transport Canada AD CF-2023-65 
includes Bombardier, Inc., Model BD-700-1A10 airplane having serial 
number 9001, that airplane is not included on the U.S. type certificate 
data sheet. Therefore, the applicability of this proposed AD does not 
include that airplane.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 484 airplanes of U.S. registry. The FAA estimates the following 
costs to comply with this proposed 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

[[Page 8917]]

develop on products identified in this rulemaking action.

Regulatory Findings

    The FAA determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
