[FR Doc. 2024–21183 Filed 9–17–24; 8:45 am] BILLING CODE 4910–13–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2024–1469; Project Identifier MCAI–2024–00130–T; Amendment 39–22810; AD 2024–16–04] RIN 2120–AA64 Airworthiness Directives; Bombardier, Inc. Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Final rule. AGENCY: The FAA is superseding Airworthiness Directive (AD) 2009–25– 13, which applied to certain Bombardier, Inc., Model BD–100–1A10 (Challenger 300) airplanes. AD 2009– 25–13 required the deactivation of the left-hand (LH) baggage bay heater mat. Since the FAA issued AD 2009–25–13, Bombardier developed a new design solution for the potential uncontrolled heating of the baggage bay sidewall heater mat. This AD retains the requirements of AD 2009–25–13 and requires modifying the baggage bay sidewall interior panel, heater mat, and water tank heater installation, and doing functional testing. Upon the completion of the new actions, the retained requirements of AD 2009–25–13 will terminate. This AD also revises the applicability. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective October 23, 2024. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of October 23, 2024.

SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2009–25–13, Amendment 39–16133 (74 FR 65401, December 10, 2009) (AD 2009–25–13). AD 2009–25–13 applied to certain Bombardier, Inc., Model BD–100–1A10 airplanes. AD 2009–25–13 required the deactivation of the LH baggage bay heater. The FAA issued AD 2009–25–13 to address the possibility of uncontrolled heating by the heater panel, and on the baggage bay compartment, that could result in a fire in the baggage bay. The NPRM published in the Federal Register on May 22, 2024 (89 FR 44930). The NPRM was prompted by AD CF– 2023–72, dated October 18, 2023, issued by Transport Canada, which is the aviation authority for Canada (Transport Canada AD CF–2023–72) (also referred to as the MCAI). The MCAI states that new procedures have been developed for modifications of the baggage bay sidewall interior panel, heater mat, and water tank heater installation that will address the unsafe condition. In the NPRM, the FAA proposed to continue to require the actions in AD 2009–25–13, and further require modifying the baggage bay sidewall interior panel, heater mat, and water tank heater installation, and doing functional testing. In the NPRM, the FAA proposed that, upon the completion of the new actions, the retained requirements of AD 2009–25– 13 would terminate. In the NPRM, the FAA also proposed to revise the applicability to clarify that the AD applies to airplanes having certain serial numbers (which equates to those equipped with sidewall heater having part number (P/N) 3436–06–1/0) instead of part numbers which could be misread. The FAA is issuing this AD to address the unsafe condition on these products. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2024–1469. Discussion of Final Airworthiness Directive Comments The FAA received no comments on the NPRM or on the determination of the cost to the public. Additional Changes Made to This Final Rule In the NPRM, the FAA inadvertently stated that the NPRM proposed to prohibit the installation of affected parts. This AD does not contain a parts installation prohibition, so the FAA deleted references to such a prohibition. 76409 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 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, this AD is adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator. Material Incorporated by Reference Under 1 CFR Part 51 The FAA reviewed Bombardier Service Bulletin 100–25–35, Revision 02, dated January 11, 2016. This material specifies procedures for modifying the LH baggage bay sidewall interior panel and heater mat, installing a LH baggage bay sidewall interior panel blind insert for certain airplanes, modifying the wiring of the LH and right-hand (RH) baggage bay sidewall heater mats, re-identifying the LH heater mat as P/N 3436–07, installing LH and RH heater pictograms for certain airplanes, modifying the water tank heater installation, and performing a functional test. This AD also requires Bombardier Service Bulletin A100–25–30, dated July 20, 2009, which the Director of the Federal Register approved for incorporation by reference as of December 28, 2009 (74 FR 65401, December 10, 2009). 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 340 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: khammond on DSKJM1Z7X2PROD with RULES ESTIMATED COSTS FOR REQUIRED ACTIONS Action Labor cost Heater mat deactivation (Retained actions from AD 2009–25–13).

According to the manufacturer, however, some or all of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected operators. 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. khammond on DSKJM1Z7X2PROD with RULES List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2021–17–02, Amendment 39–21685 (86 FR 48490, August 31, 2021) (AD 2021–17–02). AD 2021–17–02 applied to all ATR–GIE Avions de Transport Régional Model ATR42–200, –300, and –320 airplanes. AD 2021–17–02 required a one-time inspection for discrepancies of the wire bundles between the left- and righthand AOA probes and the crew alerting computer, and, depending on findings, applicable corrective actions. AD 2021– 17–02 also required for certain airplanes, modifying the captain stick shaker wiring, and for all airplanes, revising the existing AFM and applicable corresponding operational procedures to incorporate procedures for the stick pusher/shaker. The FAA issued AD 2021–17–02 to address false activation of the stall warning system due to wiring damage on the wire bundle between an AOA probe and the crew alerting computer, which could result in loss of control of the airplane during take-off and landing phases. The NPRM published in the Federal Register on October 5, 2023 (88 FR 69102). The NPRM was prompted by AD 2023–0134, dated July 5, 2023 (EASA AD 2023–0134), issued by EASA, which is the Technical Agent for the Member States of the European Union. EASA AD 2023–0134 states final modification instructions of the affected wiring were developed. In the NPRM, the FAA proposed to require installing a new AOA power supply unit and revising the existing AFM, as specified in EASA AD 2023– 0134. The FAA issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 to supersede AD 2021–17–02. The SNPRM published in the Federal Register on May 21, 2024 (89 FR 44568). The SNPRM was prompted by additional modification of the affected wiring for certain airplanes, and by the issuance of EASA AD 2023– 0191, dated November 2, 2023 (EASA AD 2023–0191) (also referred to as the MCAI). In the SNPRM, the FAA proposed to retain all of the requirements of AD 2021–17–02. The NPRM also proposed to require installing a new AOA power supply unit and removing the AFM amendment. The FAA is issuing this AD to address the unsafe condition on these products. E:\FR\FM\18SER1.SGM 18SER1

Airworthiness Directives; Bombardier, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2009-25-
13, which applied to certain Bombardier, Inc., Model BD-100-1A10 
(Challenger 300) airplanes. AD 2009-25-13 required the deactivation of 
the left-hand (LH) baggage bay heater mat. Since the FAA issued AD 
2009-25-13, Bombardier developed a new design solution for the 
potential uncontrolled heating of the baggage bay sidewall heater mat. 
This AD retains the requirements of AD 2009-25-13 and requires 
modifying the baggage bay sidewall interior panel, heater mat, and 
water tank heater installation, and doing functional testing. Upon the 
completion of the new actions, the retained requirements of AD 2009-25-
13 will terminate. This AD also revises the applicability. The FAA is 
issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective October 23, 2024.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of October 23, 
2024.

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2009-25-13, Amendment 39-16133 (74 FR 
65401, December 10, 2009) (AD 2009-25-13). AD 2009-25-13 applied to 
certain Bombardier, Inc., Model BD-100-1A10 airplanes. AD 2009-25-13 
required the deactivation of the LH baggage bay heater. The FAA issued 
AD 2009-25-13 to address the possibility of uncontrolled heating by the 
heater panel, and on the baggage bay compartment, that could result in 
a fire in the baggage bay.
    The NPRM published in the Federal Register on May 22, 2024 (89 FR 
44930). The NPRM was prompted by AD CF-2023-72, dated October 18, 2023, 
issued by Transport Canada, which is the aviation authority for Canada 
(Transport Canada AD CF-2023-72) (also referred to as the MCAI). The 
MCAI states that new procedures have been developed for modifications 
of the baggage bay sidewall interior panel, heater mat, and water tank 
heater installation that will address the unsafe condition.
    In the NPRM, the FAA proposed to continue to require the actions in 
AD 2009-25-13, and further require modifying the baggage bay sidewall 
interior panel, heater mat, and water tank heater installation, and 
doing functional testing. In the NPRM, the FAA proposed that, upon the 
completion of the new actions, the retained requirements of AD 2009-25-
13 would terminate. In the NPRM, the FAA also proposed to revise the 
applicability to clarify that the AD applies to airplanes having 
certain serial numbers (which equates to those equipped with sidewall 
heater having part number (P/N) 3436-06-1/0) instead of part numbers 
which could be misread. The FAA is issuing this AD to address the 
unsafe condition on these products.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2024-1469.

Discussion of Final Airworthiness Directive

Comments

    The FAA received no comments on the NPRM or on the determination of 
the cost to the public.

Additional Changes Made to This Final Rule

    In the NPRM, the FAA inadvertently stated that the NPRM proposed to 
prohibit the installation of affected parts. This AD does not contain a 
parts installation prohibition, so the FAA deleted references to such a 
prohibition.

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 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, this AD is adopted as proposed in 
the NPRM. None of the changes will increase the economic burden on any 
operator.

Material Incorporated by Reference Under 1 CFR Part 51

    The FAA reviewed Bombardier Service Bulletin 100-25-35, Revision 
02, dated January 11, 2016. This material specifies procedures for 
modifying the LH baggage bay sidewall interior panel and heater mat, 
installing a LH baggage bay sidewall interior panel blind insert for 
certain airplanes, modifying the wiring of the LH and right-hand (RH) 
baggage bay sidewall heater mats, re-identifying the LH heater mat as 
P/N 3436-07, installing LH and RH heater pictograms for certain 
airplanes, modifying the water tank heater installation, and performing 
a functional test.
    This AD also requires Bombardier Service Bulletin A100-25-30, dated 
July 20, 2009, which the Director of the Federal Register approved for 
incorporation by reference as of December 28, 2009 (74 FR 65401, 
December 10, 2009).
    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 340 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

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


[[Page 76410]]

    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some or all of the costs of 
this AD may be covered under warranty, thereby reducing the cost impact 
on affected operators.

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.
