Download as PDF 11164 Federal Register / Vol. 89, No. 31 / Wednesday, February 14, 2024 / Rules and Regulations E.O. 12866. Therefore, no regulatory impact analysis is required. DEPARTMENT OF TRANSPORTATION Federal Aviation Administration C. Regulatory Flexibility Act The Regulatory Flexibility Act (RFA) requires an agency to prepare a regulatory flexibility analysis for rules unless the agency certifies that the rule will not have a significant economic impact on a substantial number of small entities. The RFA applies only to rules for which an agency is required to first publish a proposed rule. See 5 U.S.C. 603(a) and 604(a). As discussed above, the 2015 Act does not require agencies to first publish a proposed rule when adjusting CMPs within their jurisdiction. Thus, the RFA does not apply to this final rule. D. Paperwork Reduction Act This document does not contain information collection requirements subject to the Paperwork Reduction Act of 1995, Public Law 104–13 (44 U.S.C. Chapter 35). E. Congressional Review Act Pursuant to the Congressional Review Act (5 U.S.C. 801, et seq.), the Office of Information and Regulatory Affairs designated this rule as not a ‘‘major rule’’ as defined by 5 U.S.C. 804(2). List of Subjects in 5 CFR Part 1201 Administrative practice and procedure, Civil rights, Government employees. For the reasons set forth above, 5 CFR part 1201 is amended as follows: PART 1201—PRACTICES AND PROCEDURES 1. The authority citation for part 1201 continues to read as follows: ■ Authority: 5 U.S.C. 1204, 1305, and 7701, and 38 U.S.C. 4331, unless otherwise noted. § 1201.126 [Amended] 2.

Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Final rule. AGENCY: The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL–600–2B16 (604 Variant) airplanes. This AD was prompted by a determination that a combination of system faults and procedural actions will cause the ground spoilers to deploy in the air. This AD requires revising the existing airplane flight manual (AFM) to add revised procedures. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective March 20, 2024. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of March 20, 2024. ADDRESSES: AD Docket: You may examine the AD docket at regulations.gov under Docket No. FAA–2023–1219; or in person at Docket Operations between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

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 CL–600–2B16 (604 Variant) airplanes. The NPRM published in the Federal Register on July 5, 2023 (88 FR 42886). The NPRM was prompted by AD CF– 2023–01, dated January 4, 2023, issued by Transport Canada (hereafter referred to as the MCAI), which is the aviation authority for Canada. The MCAI states that, during an in-service event, a combination of system faults and procedural actions caused the ground spoilers to deploy in the air. During this event, the WOW [weight-on-wheels] INPUT Caution message had posted on the engine indication and crew alerting system (EICSA) after takeoff. The WOW INPUT message persisted, even after the flightcrew executed the WOW INPUT Quick Reference Handbook (QRH) procedure. During this time, the GND SPLRS [ground spoilers] NOT ARMED message also posted, and the flightcrew consequently manually armed the ground spoilers as required by procedure. An investigation by Bombardier, Inc., revealed that a fault occurred in the proximity sensor electronic unit (PSEU), which erroneously indicated ON GROUND while the airplane was in the air. In the NPRM, the FAA proposed to require revision of the existing AFM to add revised procedures. The FAA is issuing this AD to address possible ground spoiler deployment leading to reduced controllability of the airplane, or excessive loss of altitude on final approach. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2023–1219. Discussion of Final Airworthiness Directive Comments The FAA received one comment from a commenter who supported the NPRM without change. The FAA received additional comments from Bombardier. The following presents the comments received and the FAA’s responses. E:\FR\FM\14FER1.SGM 14FER1 Federal Register / Vol. 89, No. 31 / Wednesday, February 14, 2024 / Rules and Regulations the 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 this product. Except for minor editorial changes, and any other changes described previously, this AD is adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator. Request for Later-Approved Service Information Bombardier requested that the FAA change the AD to allow the use of the AFM revisions specified ‘‘or later revisions approved by the FAA, TCCA [Transport Canada Civil Aviation], or the Bombardier DAO [Design Approval Organization].’’ The FAA disagrees with the commenter’s request. The FAA may not refer to any future document that does not yet exist in an AD because 1 CFR 51.1(f) states a publication’s incorporation by reference is limited to its approved edition; future publication amendments or revisions are outside this inclusion. Further, paragraph (g) of this AD requires operators to incorporate ‘‘the information specified in’’ the specified AFM documents. If operators incorporate a later revision of an AFM document that contains the same information as the specified AFM document, then they are in compliance with paragraph (g) of this AD. However, if there are changes to procedures in later revisions, operators may request an alternative method of compliance with this AD under the provisions of paragraph (h)(1) of this AD. Additional Changes Made to This Final Rule In the NPRM, the FAA inadvertently referred to Sub-sub-section K, ‘‘Ground Spoilers Unsafe,’’ of Bombardier Challenger 604 Airplane Flight Manual, Publication No. PSP 604–1, Revision 125, dated March 14, 2022. The ‘‘Ground Spoilers Unsafe,’’ procedure of that document is actually ‘‘Sub-subsection L.’’ Therefore, the FAA has revised all references of ‘‘Sub-subsection K’’ to ‘‘Sub-sub-section L.’’ Conclusion 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 referenced above. The FAA reviewed the relevant data, considered Related Service Information Under 1 CFR Part 51 The FAA reviewed the following service information, which specifies revised Abnormal Procedures of the AFM for Ground Spoilers Unsafe and Weight-on-Wheels Input Fault procedures. These documents are distinct since they apply to different airplane models and configurations. • Sub-sub-section L, ‘‘Ground Spoilers Unsafe,’’ of sub-section 1, ‘‘Flight Controls,’’ of Section 05–11, ‘‘Flight Controls,’’ of Chapter 5, ABNORMAL PROCEDURES, of Bombardier Challenger 604 Airplane Flight Manual, Publication No. PSP 604–1, Revision 125, dated March 14, 2022.

(For obtaining Bombardier Challenger 604 Airplane Flight Manual, Publication No. PSP 604–1, use Document Identification No. CH 604 AFM.) • Sub-sub-section L, ‘‘Ground Spoilers Unsafe,’’ of sub-section 1, ‘‘Flight Controls,’’ of Section 05–11, ‘‘Flight Controls,’’ of Chapter 5, ABNORMAL PROCEDURES, of Bombardier Challenger 605 Airplane Flight Manual, Publication No. PSP 605–1, Revision 63, dated March 14, 2022. (For obtaining Bombardier 11165 Challenger 605 Airplane Flight Manual, Publication No. PSP 605–1, use Document Identification No. CH 605 AFM.) • Sub-sub-section H, ‘‘Weight-onWheels Input Fault,’’ of sub-section 1, ‘‘Landing Gear, Wheel and Brake System,’’ of Section 05–16, ‘‘Landing Gear, Wheel and Brake System,’’ of Chapter 5, ABNORMAL PROCEDURES, of Bombardier Challenger 605 Airplane Flight Manual, Publication No. PSP 605–1, Revision 63, dated March 14, 2022. (For obtaining Bombardier Challenger 605 Airplane Flight Manual, Publication No. PSP 605–1, use Document Identification No. CH 605 AFM.) • Sub-sub-section L, ‘‘Ground Spoilers Unsafe,’’ of sub-section 1, ‘‘Flight Controls,’’ of Section 05–11, ‘‘Flight Controls,’’ of Chapter 5, ABNORMAL PROCEDURES, of Bombardier Challenger 650 Airplane Flight Manual, Publication No. PSP 650–1, Revision 28, dated March 14, 2022.

Costs of Compliance The FAA estimates that this AD affects 44 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: ddrumheller on DSK120RN23PROD with RULES1 ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 1 work-hour × $85 per hour = $85 .............................................................................................. $0 $85 $3,740 VerDate Sep<11>2014 16:56 Feb 13, 2024 Jkt 262001 PO 00000 Frm 00003 Fmt 4700 Sfmt 4700 E:\FR\FM\14FER1.SGM 14FER1 11166 Federal Register / Vol. 89, No. 31 / Wednesday, February 14, 2024 / Rules and Regulations 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.

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 CL-600-2B16 (604 Variant) airplanes. 
This AD was prompted by a determination that a combination of system 
faults and procedural actions will cause the ground spoilers to deploy 
in the air. This AD requires revising the existing airplane flight 
manual (AFM) to add revised procedures. The FAA is issuing this AD to 
address the unsafe condition on these products.

DATES: This AD is effective March 20, 2024.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of March 20, 
2024.

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 CL-600-2B16 (604 Variant) airplanes. The NPRM published in 
the Federal Register on July 5, 2023 (88 FR 42886). The NPRM was 
prompted by AD CF-2023-01, dated January 4, 2023, issued by Transport 
Canada (hereafter referred to as the MCAI), which is the aviation 
authority for Canada. The MCAI states that, during an in-service event, 
a combination of system faults and procedural actions caused the ground 
spoilers to deploy in the air. During this event, the WOW [weight-on-
wheels] INPUT Caution message had posted on the engine indication and 
crew alerting system (EICSA) after takeoff. The WOW INPUT message 
persisted, even after the flightcrew executed the WOW INPUT Quick 
Reference Handbook (QRH) procedure. During this time, the GND SPLRS 
[ground spoilers] NOT ARMED message also posted, and the flightcrew 
consequently manually armed the ground spoilers as required by 
procedure. An investigation by Bombardier, Inc., revealed that a fault 
occurred in the proximity sensor electronic unit (PSEU), which 
erroneously indicated ON GROUND while the airplane was in the air.
    In the NPRM, the FAA proposed to require revision of the existing 
AFM to add revised procedures. The FAA is issuing this AD to address 
possible ground spoiler deployment leading to reduced controllability 
of the airplane, or excessive loss of altitude on final approach.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2023-1219.

Discussion of Final Airworthiness Directive

Comments

    The FAA received one comment from a commenter who supported the 
NPRM without change.
    The FAA received additional comments from Bombardier. The following 
presents the comments received and the FAA's responses.

[[Page 11165]]

Request for Later-Approved Service Information

    Bombardier requested that the FAA change the AD to allow the use of 
the AFM revisions specified ``or later revisions approved by the FAA, 
TCCA [Transport Canada Civil Aviation], or the Bombardier DAO [Design 
Approval Organization].''
    The FAA disagrees with the commenter's request. The FAA may not 
refer to any future document that does not yet exist in an AD because 1 
CFR 51.1(f) states a publication's incorporation by reference is 
limited to its approved edition; future publication amendments or 
revisions are outside this inclusion.
    Further, paragraph (g) of this AD requires operators to incorporate 
``the information specified in'' the specified AFM documents. If 
operators incorporate a later revision of an AFM document that contains 
the same information as the specified AFM document, then they are in 
compliance with paragraph (g) of this AD. However, if there are changes 
to procedures in later revisions, operators may request an alternative 
method of compliance with this AD under the provisions of paragraph 
(h)(1) of this AD.

Additional Changes Made to This Final Rule

    In the NPRM, the FAA inadvertently referred to Sub-sub-section K, 
``Ground Spoilers Unsafe,'' of Bombardier Challenger 604 Airplane 
Flight Manual, Publication No. PSP 604-1, Revision 125, dated March 14, 
2022. The ``Ground Spoilers Unsafe,'' procedure of that document is 
actually ``Sub-sub-section L.'' Therefore, the FAA has revised all 
references of ``Sub-sub-section K'' to ``Sub-sub-section L.''

Conclusion

    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 
referenced above. The FAA reviewed the relevant data, considered the 
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 this product. Except for minor editorial 
changes, and any other changes described previously, this AD is adopted 
as proposed in the NPRM. None of the changes will increase the economic 
burden on any operator.

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.
