Airworthiness Directives; Bombardier, Inc., Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain 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 report that fast and easy access to the portable 
oxygen bottle may be prevented by the portable oxygen bottle 
installation's upper bracket latch assembly catching on the pressure 
gauge tube or on the pressure gauge bezel of the portable oxygen 
bottle. This AD requires a check to identify the manufacturer and part 
number of the portable oxygen bottle installation, and, if necessary, 
modification of the portable oxygen bottle installation. The FAA is 
issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective November 3, 2020.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of November 3, 
2020.

SUPPLEMENTARY INFORMATION:

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2019-26, dated July 9, 
2019 (also referred to as the Mandatory Continuing Airworthiness 
Information, or ``the MCAI''), to correct an unsafe condition for 
certain Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601), 
and CL-600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes. You may 
examine the MCAI in the AD docket on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2020-
0203.
    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-600-1A11 (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 March 23, 2020 (85 FR 16284). The NPRM was prompted 
by a report that fast and easy access to the portable oxygen bottle may 
be prevented by the portable oxygen bottle installation's upper bracket 
latch assembly catching on the pressure gauge tube or on the pressure 
gauge bezel of the portable oxygen bottle. The NPRM proposed to require 
a check to identify the manufacturer and part number of the portable 
oxygen bottle installation, and, if necessary, modification of the 
portable oxygen bottle installation. The FAA is issuing this AD to 
address the portable oxygen bottle installation's upper bracket latch 
assembly catching on the pressure gauge tube or on the pressure gauge 
bezel of the portable oxygen bottle, which, if not detected and 
corrected, could prevent fast and easy access to the portable oxygen 
bottle in an emergency situation. See the MCAI for additional 
background information.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The following presents the comment received 
on the NPRM and the FAA's response to each comment.

Support for the NPRM

    An anonymous commenter had no objection to the NPRM.

Request To Revise or Clarify the Applicability of Paragraph (i) of the 
Proposed AD

    NetJets requested that the FAA either revise the language in the 
first sentence of paragraph (i) of the proposed AD to clearly state 
that the paragraph applies to airplanes having a serial number of 6119 
and below that is not listed in section 1.A. of the applicable 
Bombardier service information specified in figure 1 to paragraphs (g), 
(h), and (i) of the proposed AD, or that the FAA clarify paragraph 
(c)(3) of the proposed AD to state that all serial numbers are 
affected.
    The FAA agrees to clarify. Paragraph (i) of the proposed AD is 
applicable to only airplanes having the serial numbers specified in 
paragraph (c) of this AD, but not listed in section 1.A. of the 
applicable Bombardier service information specified in figure 1 to 
paragraphs (g), (h), and (i) of this AD, and equipped with specified 
part numbers of Scott (Avox/Zodiac) 5500 or 5600 series 11 cubic foot 
portable oxygen bottle(s). As such, any serial number not specified in 
paragraph (c)(3) of this AD for Bombardier Inc. Model CL-600-2B16 (601-
3A, 601-3R, and 604 Variants) airplanes, is not affected by paragraph 
(i) of this AD. The FAA has not changed this AD in this regard.

Conclusion

    The FAA reviewed the relevant data, considered the comments 
received, and determined that air safety and the public interest 
require adopting this final rule as proposed, except for minor 
editorial changes. The FAA has determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

----------------------------------------------------------------------------------------------------------------
3 work-hours x $85 per hour = $255     $1,530 per installation  $1,785 per installation  $335,580 per
 per installation.                                                                        installation.

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.
