Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background Transport Canada, which is the aviation authority for Canada, has issued Transport Canada AD CF–2022– 50, dated August 25, 2022 (also referred to after this as the MCAI), to correct an unsafe condition on certain Bombardier, Inc., Model CL–600–1A11 (600), CL– 600–2A12 (601), and CL–600–2B16 (601–3A, 601–3R, and 604 Variants) airplanes. The MCAI states that lanyards of passenger mask dispensing units installed in the affected airplanes are too long to meet the proper length specifications of the aircraft. This condition, if not corrected, could result in the inability to initiate the flow of oxygen to the mask when required in an emergency situation, with no indication to the passenger that they are not receiving oxygen. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2022–1654. Related Service Information Under 1 CFR Part 51 Bombardier has issued the following service information, which describes procedures for identifying part numbers of the drop-down oxygen boxes, performing drop-down oxygen mask E:\FR\FM\27DEP1.SGM 27DEP1 79260 Federal Register / Vol. 87, No. 247 / Tuesday, December 27, 2022 / Proposed Rules reach testing, marking failed seats as inoperative with placards, and replacing affected oxygen masks: • Service Bulletin 600–0777, dated December 13, 2021. • Service Bulletin 601–1109, Revision 01, dated May 6, 2022. • Service Bulletin 604–35–007, Revision 01, dated May 6, 2022. These documents are distinct since they apply to different airplane models. This service information 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 These products are 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 service information described 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 accomplishing the actions specified in the service information already described. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 301 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: 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 $25,585 The FAA estimates the following costs to do any necessary on-condition actions that would be required based on the results of any required actions. The FAA has no way of determining the number of aircraft that might need these on-condition actions: ESTIMATED COSTS OF ON-CONDITION ACTIONS Labor cost Parts cost Cost per product 2 work-hours × $85 per hour = $170 ...................................................................................................................... $100 $270 TKELLEY on DSK125TN23PROD with PROPOSALS 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 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 VerDate Sep<11>2014 23:06 Dec 23, 2022 Jkt 259001 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. § 39.13 List of Subjects in 14 CFR Part 39 (c) Applicability Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

Background

    Transport Canada, which is the aviation authority for Canada, has 
issued Transport Canada AD CF-2022-50, dated August 25, 2022 (also 
referred to after this as the MCAI), to correct an unsafe condition on 
certain Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601), 
and CL-600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes. The MCAI 
states that lanyards of passenger mask dispensing units installed in 
the affected airplanes are too long to meet the proper length 
specifications of the aircraft. This condition, if not corrected, could 
result in the inability to initiate the flow of oxygen to the mask when 
required in an emergency situation, with no indication to the passenger 
that they are not receiving oxygen.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2022-1654.

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

    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

    Air transportation, Aircraft, Aviation safety, Incorporation by 
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.

[[Page 79261]]

(d) Subject

    Air Transport Association (ATA) of America Code 35, Oxygen 
System.

(e) Unsafe Condition

    This AD was prompted by reports of passenger oxygen mask 
dispensing units installed in the affected airplanes with lanyards 
that are too long to meet the proper length specifications of the 
airplane. The FAA is issuing this AD to address the inability to 
initiate flow of oxygen to the mask. The unsafe condition, if not 
addressed, could result in no indication to the passenger that they 
are not receiving oxygen in an emergency situation.

(f) Compliance

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

(g) Inspection and Replacement

    Within 5 years after the effective date of this AD, determine 
the part number of the drop-down oxygen box, in accordance with 
Section 2.B. of the Accomplishment Instructions of the applicable 
service information identified in paragraphs (c)(1) through (4) of 
this AD.
    (1) If any drop-down oxygen box part number (P/N) installed on 
the airplane matches any P/N listed in Table 1 of Section 2.B. of 
the applicable service information: Before further flight, perform 
drop-down oxygen mask reach testing in accordance with Section 
2.B.(2) of the Accomplishment Instructions of the applicable service 
information identified in paragraphs (c)(1) through (4) of this AD.
    (i) If the test result is PASS: Before further flight, replace 
the drop-down oxygen box assembly in accordance with Section 2.C., 
and test the passenger oxygen supply system in accordance with 
Section 2.D.(2), of the applicable service information identified in 
paragraphs (c)(1) through (4) of this AD.
    (ii) If the test result is FAIL for any individual seat: Before 
further flight, mark the failed seat as inoperative in accordance 
with Section 2.B.(3) of the applicable service information specified 
in paragraphs (c)(1) through (4) of this AD.
    (2) If the part number of any drop-down oxygen box assembly 
installed on the airplane is not found in Table 1 of Section 2.B. of 
the applicable service information identified in paragraphs (c)(1) 
through (4) of this AD: Before further flight, do actions to correct 
the unsafe condition using a method approved in accordance with the 
procedures specified in paragraph (i)(1) of this AD.

(h) Credit for Previous Actions

    This paragraph provides credit for actions required by paragraph 
(g) of this AD, if those actions were performed before the effective
