Background Transport Canada, which is the aviation authority for Canada, has issued Transport Canada AD CF–2024– 27, dated July 24, 2024 (Transport Canada AD CF–2024–27) (also referred to as the MCAI), to correct an unsafe condition on certain Bombardier, Inc., Model BD–700–1A10 and BD–700– 1A11 airplanes. The MCAI states that incorrect approach speed adders and landing distance factors were discovered in the AFM tables for the SLAT–FLAP FAIL (Caution) Crew Alerting System (CAS) message and the jammed or inoperative slat/flap control lever (SFCL) non-normal procedures. The incorrect speed adders and landing distance factors present a potentially unsafe condition due to the shortfall between the actual performance and the approved performance. The FAA is proposing this AD to address incorrect speed adders and landing distance factors in AFM tables. The unsafe condition, if not addressed, could lead to increased workload for the flightcrew, possible stick shaker activation (stall warning) due to a need to increase speed beyond the published AFM speed adder, and increased landing distance beyond published nonnormal landing distance factors. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2025–0477. Material Incorporated by Reference Under 1 CFR Part 51 The FAA reviewed the following Bombardier material.

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, it has notified the 13711 FAA of the unsafe condition described in the MCAI and material referenced above. The FAA is issuing this NPRM after determining that the unsafe condition described previously is likely to exist or develop on other products of the same type design. Proposed AD Requirements in This NPRM This proposed AD would require revising the existing AFM to correct table information in procedures to address certain slat-flap conditions (Slat-flap fail (Caution) CAS message, or a jammed or inoperative SFCL). Compliance With AFM Revisions Transport Canada AD CF–2024–27 requires operators to ‘‘advise all flight crews’’ of revisions to the AFM, and thereafter to ‘‘operate the aeroplane accordingly.’’ However, this proposed AD would not specifically require those actions as those actions are already required by FAA regulations. FAA regulations require operators furnish to pilots any changes to the AFM (for example, 14 CFR 121.137), and to ensure the pilots are familiar with the AFM (for example, 14 CFR 91.505). As with any other flightcrew training requirement, training on the updated AFM content is tracked by the operators and recorded in each pilot’s training record, which is available for the FAA to review. FAA regulations also require pilots to follow the procedures in the existing AFM including all updates. 14 CFR 91.9 requires that any person operating a civil aircraft must comply with the operating limitations specified in the AFM. Therefore, including a requirement in this proposed AD to operate the airplane according to the revised AFM would be redundant and unnecessary. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 476 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: khammond on DSK9W7S144PROD with PROPOSALS ESTIMATED COSTS FOR REQUIRED ACTIONS Cost per product Labor cost Parts cost 1 work-hour × $85 per hour = $85 .................................................................... None ........................................ 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 VerDate Sep<11>2014 16:00 Mar 25, 2025 Jkt 265001 the FAA Administrator. Subtitle VII: Aviation Programs, describes in more detail the scope of the Agency’s authority. PO 00000 Frm 00007 Fmt 4702 Sfmt 4702 $85 Cost on U.S. operators $40,460 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 E:\FR\FM\26MRP1.SGM 26MRP1 Federal Register / Vol. 90, No. 57 / Wednesday, March 26, 2025 / Proposed Rules 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. List of Subjects in 14 CFR part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Regulatory Findings PART 39—AIRWORTHINESS DIRECTIVES khammond on DSK9W7S144PROD with PROPOSALS 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. VerDate Sep<11>2014 16:00 Mar 25, 2025 Jkt 265001 The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 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. § 39.13 [Amended] 2.

(d) Subject Air Transport Association (ATA) of America Code 27, Flight Controls. (e) Unsafe Condition This AD was prompted by a report that incorrect information was found in certain calculation tables in a section of the airplane flight manual (AFM) that addresses certain slat-flap conditions. The FAA is issuing this AD to address incorrect speed adders and landing distance factors in AFM tables. The unsafe condition, if not addressed, could lead to increased workload for the flightcrew, possible stick shaker activation (stall warning) due to a need to increase speed beyond the published AFM speed adder, and increase landing distance beyond published non-normal landing distance factors. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Revision of Existing AFM Within 30 days after the effective date of this AD, revise the existing AFM to incorporate the information in the applicable sections of the applicable AFMs identified in table 1 to paragraph (g) of this AD.

Airworthiness Directives; Bombardier, Inc., Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 
airplanes. This proposed AD was prompted by a report that incorrect 
information was found in certain calculation tables in a section of the 
airplane flight manual (AFM) that addresses certain slat-flap 
conditions. This proposed AD would require revising the Non-Normal 
Procedures section of the existing AFM to provide the flightcrew with 
corrected procedures to use in certain slat-flap conditions. The FAA is 
proposing this AD to address the unsafe condition on these products.

DATES: The FAA must receive comments on this proposed AD by May 12, 
2025.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Background

    Transport Canada, which is the aviation authority for Canada, has 
issued Transport Canada AD CF-2024-27, dated July 24, 2024 (Transport 
Canada AD CF-2024-27) (also referred to as the MCAI), to correct an 
unsafe condition on certain Bombardier, Inc., Model BD-700-1A10 and BD-
700-1A11 airplanes. The MCAI states that incorrect approach speed 
adders and landing distance factors were discovered in the AFM tables 
for the SLAT-FLAP FAIL (Caution) Crew Alerting System (CAS) message and 
the jammed or inoperative slat/flap control lever (SFCL) non-normal 
procedures. The incorrect speed adders and landing distance factors 
present a potentially unsafe condition due to the shortfall between the 
actual performance and the approved performance.
    The FAA is proposing this AD to address incorrect speed adders and 
landing distance factors in AFM tables. The unsafe condition, if not 
addressed, could lead to increased workload for the flightcrew, 
possible stick shaker activation (stall warning) due to a need to 
increase speed beyond the published AFM speed adder, and increased 
landing distance beyond published non-normal landing distance factors.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2025-0477.

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, it 
has notified the FAA of the unsafe condition described in the MCAI and 
material referenced above. The FAA is issuing this NPRM after 
determining that the unsafe condition described previously is likely to 
exist or develop on other products of the same type design.

Proposed AD Requirements in This NPRM

    This proposed AD would require revising the existing AFM to correct 
table information in procedures to address certain slat-flap conditions 
(Slat-flap fail (Caution) CAS message, or a jammed or inoperative 
SFCL).

Compliance With AFM Revisions

    Transport Canada AD CF-2024-27 requires operators to ``advise all 
flight crews'' of revisions to the AFM, and thereafter to ``operate the 
aeroplane accordingly.'' However, this proposed AD would not 
specifically require those actions as those actions are already 
required by FAA regulations. FAA regulations require operators furnish 
to pilots any changes to the AFM (for example, 14 CFR 121.137), and to 
ensure the pilots are familiar with the AFM (for example, 14 CFR 
91.505). As with any other flightcrew training requirement, training on 
the updated AFM content is tracked by the operators and recorded in 
each pilot's training record, which is available for the FAA to review. 
FAA regulations also require pilots to follow the procedures in the 
existing AFM including all updates. 14 CFR 91.9 requires that any 
person operating a civil aircraft must comply with the operating 
limitations specified in the AFM. Therefore, including a requirement in 
this proposed AD to operate the airplane according to the revised AFM 
would be redundant and unnecessary.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 476 airplanes of U.S. registry. The FAA estimates the following 
costs to comply with this proposed AD:

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

[[Page 13712]]

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

    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.

List of Subjects in 14 CFR part 39

reference, Safety.

The Proposed Amendment

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

PART 39--AIRWORTHINESS DIRECTIVES

0
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]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive:

Bombardier, Inc.: Docket No. FAA-2025-0477; Project Identifier MCAI-
2024-00422-T.

(a) Comments Due Date

    The FAA must receive comments on this airworthiness directive 
(AD) by May 12, 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 
number 9002 through 60086 inclusive, 60088 through 60091 inclusive, 
60098, 60100, 60105, 60107, and 60111.

(d) Subject

    Air Transport Association (ATA) of America Code 27, Flight 
Controls.

(e) Unsafe Condition

    This AD was prompted by a report that incorrect information was 
found in certain calculation tables in a section of the airplane 
flight manual (AFM) that addresses certain slat-flap conditions. The 
FAA is issuing this AD to address incorrect speed adders and landing 
distance factors in AFM tables. The unsafe condition, if not 
addressed, could lead to increased workload for the flightcrew, 
possible stick shaker activation (stall warning) due to a need to 
increase speed beyond the published AFM speed adder, and increase 
landing distance beyond published non-normal landing distance 
factors.
