[Docket No. FAA-2020-0203; Product Identifier 2019-NM-142-AD]
RIN 2120-AA64
Airworthiness Directives; Bombardier, Inc., Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to adopt 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 proposed 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 proposed AD would 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 proposing this AD to address the unsafe
condition on these products.
DATES: The FAA must receive comments on this proposed AD by May
7, 2020.
ADDRESSES: You may send comments, using the procedures found in
14 CFR
11.43 and 11.45, by any of the following methods:

Discussion
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian AD CF-2019-26, dated July 9,
2019 (referred to after this 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.
This proposed 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. The FAA is proposing this AD to address this condition,
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.
Related Service Information Under 1 CFR Part 51
Bombardier has issued the following service information:
Bombardier Service Bulletin 600-0772, dated June 29, 2018;
Bombardier Service Bulletin 601-0646, dated June 29, 2018;
Bombardier Service Bulletin 604-35-006, dated June 29, 2018;
Bombardier Service Bulletin 605-35-005, dated June 29, 2018;
Bombardier Service Bulletin 650-35-001, dated June 29, 2018.
This service information describes procedures for 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. 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
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to a bilateral agreement with the State of Design Authority, the FAA
has been notified of the unsafe condition described in the MCAI and
service information referenced above. The FAA is proposing this AD
because the agency evaluated all the relevant information and
determined the unsafe condition described previously is likely to exist
or develop on other products of the same type design.
Proposed Requirements of This NPRM
This proposed AD would require accomplishing the actions specified
in the service information described previously, except as discussed
under "Differences Between this Proposed AD and the MCAI or Service
Information."
Differences Between This Proposed AD and the MCAI or Service
Information
The MCAI specifies that airplanes having serial numbers not listed
in the applicable service information must do certain actions in
accordance with the applicable service information. This proposed AD
would require airplanes having serial numbers not listed in the
applicable service information to do those actions in accordance with
the procedures specified in paragraph (j)(2) of this proposed AD.
Costs of Compliance
The FAA estimates that this proposed AD affects 188 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 |
3 work-hours x $85 per hour =
$255 per installation |
$1,530 per installation |
$1,785 per installation |
$335,580 per 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
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) 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.
