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 all Bombardier, Inc., Model CL–600–1A11 (600), CL–600–2A12 (601), and CL–600–2B16 (601–3A, 601– 3R, and 604 Variants) airplanes. The NPRM published in the Federal Register on December 6, 2022 (87 FR 74535). The NPRM was prompted by AD CF–2022–10, dated March 10, 2022, (referred to after this as the MCAI) issued by Transport Canada, which is the aviation authority for Canada. The MCAI states that Bombardier, Inc., determined that, due to a lack of flightcrew awareness, smoke hoods with a certain part number installed throughout the airplane could be mistaken for PBE. The MCAI requires that operators verify if a smoke hood with a certain part number is installed in any location on the airplane and, depending on the results, removing the smoke hood and associated placards PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 and installing new placards. The MCAI states that in a fire or smoke event the flightcrew might initially attempt to use the smoke hood believing it to be PBE, which could result in a delay in identifying the source of the smoke or fire. In the NPRM, the FAA proposed to require an inspection or records review to determine if any smoke hood with a certain part number is installed in any location on the airplane and, depending on the results, removing the smoke hood and associated placards and installing new placards. 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– 2022–1572. Discussion of Final Airworthiness Directive Comments The FAA received a comment from one commenter, Boeing Executive Flight Operations. The following presents the comment received on the NPRM and the FAA’s response to the comment. Request To Update the Service Information to the Latest Revision Boeing Executive Flight Operations requested that the FAA include Bombardier Service Bulletin 650–25– 016, Revision 01, dated June 07, 2022, for Model CL–600–2B16 (604 Variants) Serial Number 6050 to 6099. The FAA infers that the commenter is requesting that the proposed AD be revised to refer to Bombardier Service Bulletin 650–25– 016, Revision 01, dated June 07, 2022 (the proposed AD refers to Bombardier Service Bulletin 650–25–016, dated September 22, 2021, as the appropriate source of service information). The FAA agrees to update this final rule to reference Bombardier Service Bulletin 650–25–016, Revision 01, dated June 07, 2022, which adds minor changes that do not affect the substantive requirements proposed in the NPRM. The FAA has revised paragraph (h)(5) of this AD to specify that required actions be done in accordance with Bombardier Service Bulletin 650–25–016, Revision 01, dated June 07, 2022; or Bombardier Service Bulletin 650–25–016, dated September 22, 2021.

The FAA has no way of determining the number of aircraft that might need these on-condition actions: lotter on DSK11XQN23PROD with RULES1 ESTIMATED COSTS OF ON-CONDITION ACTIONS Labor cost Parts cost Cost per product 1 work-hour × $85 per hour = $85 .......................................................................................................................... $9 $94 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. 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.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all 
Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601), and CL-
600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes. This AD was 
prompted by a determination that, due to a lack of flightcrew 
awareness, smoke hoods with a certain part number installed throughout 
the airplane could be mistaken for protective breathing equipment 
(PBE). This AD requires an inspection or records review to determine if 
any smoke hood with a certain part number is installed in any location 
on the airplane and, depending on the results, removing the smoke hood 
and associated placards and installing new placards. The FAA is issuing 
this AD to address the unsafe condition on these products.

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 all Bombardier, Inc., 
Model CL-600-1A11 (600), CL-600-2A12 (601), and CL-600-2B16 (601-3A, 
601-3R, and 604 Variants) airplanes. The NPRM published in the Federal 
Register on December 6, 2022 (87 FR 74535). The NPRM was prompted by AD 
CF-2022-10, dated March 10, 2022, (referred to after this as the MCAI) 
issued by Transport Canada, which is the aviation authority for Canada. 
The MCAI states that Bombardier, Inc., determined that, due to a lack 
of flightcrew awareness, smoke hoods with a certain part number 
installed throughout the airplane could be mistaken for PBE. The MCAI 
requires that operators verify if a smoke hood with a certain part 
number is installed in any location on the airplane and, depending on 
the results, removing the smoke hood and associated placards and 
installing new placards. The MCAI states that in a fire or smoke event 
the flightcrew might initially attempt to use the smoke hood believing 
it to be PBE, which could result in a delay in identifying the source 
of the smoke or fire.
    In the NPRM, the FAA proposed to require an inspection or records 
review to determine if any smoke hood with a certain part number is 
installed in any location on the airplane and, depending on the 
results, removing the smoke hood and associated placards and installing 
new placards. 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-2022-1572.

Discussion of Final Airworthiness Directive

Comments

    The FAA received a comment from one commenter, Boeing Executive 
Flight Operations. The following presents the comment received on the 
NPRM and the FAA's response to the comment.

Request To Update the Service Information to the Latest Revision

    Boeing Executive Flight Operations requested that the FAA include 
Bombardier Service Bulletin 650-25-016, Revision 01, dated June 07, 
2022, for Model CL-600-2B16 (604 Variants) Serial Number 6050 to 6099. 
The FAA infers that the commenter is requesting that the proposed AD be 
revised to refer to Bombardier Service Bulletin 650-25-016, Revision 
01, dated June 07, 2022 (the proposed AD refers to Bombardier Service 
Bulletin 650-25-016, dated September 22, 2021, as the appropriate 
source of service information).
    The FAA agrees to update this final rule to reference Bombardier 
Service Bulletin 650-25-016, Revision 01, dated June 07, 2022, which 
adds minor changes that do not affect the substantive requirements 
proposed in the NPRM. The FAA has revised paragraph (h)(5) of this AD 
to specify that required actions be done in accordance with Bombardier 
Service Bulletin 650-25-016, Revision 01, dated June 07, 2022; or 
Bombardier Service Bulletin 650-25-016, dated September 22, 2021.

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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 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:

2023-06-02 Inc: Amendment 39-22388; Docket No. FAA-2022-1572; 
Project Identifier MCAI-2022-00350-T.

(a) Effective Date

    This airworthiness directive (AD) is effective May 18, 2023.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all Bombardier, Inc., airplanes, certificated 
in any category, as identified in paragraphs (c)(1) through (3) of 
this AD.

[[Page 22357]]

    (1) Model CL-600-1A11 (600) airplanes.
    (2) Model CL-600-2A12 (601) airplanes.
    (3) Model CL-600-2B16 (601-3A, 601-3R, and 604 Variants) 
airplanes.

(d) Subject

    Air Transport Association (ATA) of America Code: 25, Equipment/
furnishings.

(e) Unsafe Condition

    This AD was prompted by a determination that, due to a lack of 
flightcrew awareness, smoke hoods with a certain part number 
installed throughout the airplane could be mistaken for protective 
breathing equipment (PBE). The FAA is issuing this AD to address, in 
a fire or smoke event, that the flightcrew might initially attempt 
to use the smoke hood believing it to be PBE. The unsafe condition, 
if not addressed, could result in a delay in identifying the source 
of the smoke or fire.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Inspection

    Within 12 months after the effective date of this AD: Do an 
inspection to determine if any smoke hood having part number (P/N) 
MR-10008N is installed in the flight deck, forward wardrobe, or any 
other location in the airplane. A review of airplane maintenance 
records is acceptable in lieu of this inspection if the part number 
of the smoke hood can be conclusively determined from that review.

(h) Corrective Action

    If, during the inspection or records review required by 
paragraph (g) of this AD, any smoke hood having P/N MR-10008N is 
found on the airplane, within 12 months after the effective date of 
this AD, remove the smoke hood, including any associated placards, 
and install a new placard, in accordance with Section 2.B. of the 
Accomplishment Instructions of the applicable Bombardier service 
bulletin specified in paragraphs (h)(1) through (5) of this AD; or 
the method specified in paragraph (h)(6) of this AD; as applicable.
