Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-2A12 airplanes. This proposed AD was prompted by a report that the flightcrew and passenger oxygen system's refill and capillary lines may have been contaminated by sealant and cotton fibers. This proposed AD would require an inspection to determine the serial numbers of the oxygen cylinders installed and replacement of each affected oxygen cylinder and regulator assembly (OCRA). The FAA is proposing this AD to address the unsafe condition on these products.

Background
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued TCCA AD CF-2022-07, dated March 1,
2022 (TCCA AD CF-2022-07) (also referred to after this as the MCAI), to
correct an unsafe condition for certain Bombardier, Inc., Model BD-700-
2A12 airplanes. You may examine the MCAI in the AD docket at
<a href="http://regulations.gov">regulations.gov</a> by searching for and locating Docket No. FAA-2022-1065.
This proposed AD was prompted by a report that the flightcrew and
passenger oxygen system's refill and capillary lines may have been
contaminated by sealant and cotton fibers. Any contamination is
expected to collect in the OCRA filters. The FAA is proposing this AD
to address the contamination, which may cause a blockage of the oxygen
system components and result in a reduction of oxygen flow, reduce the
total amount of available oxygen, or create a fire hazard. See the MCAI
for additional background information.
Related Service Information Under 1 CFR Part 51
Bombardier has issued Service Bulletin 700-35-7502, dated January
26, 2022. This service information describes procedures for an
inspection to determine the serial numbers of the oxygen cylinders
installed and replacement of each affected OCRA with a new or reworked
OCRA. 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 the FAA's 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 FAA 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 AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in the service information already described.
[[Page 53423]]
Difference Between This NPRM and the MCAI
Although TCCA AD CF-2022-07 does not specify prohibiting the
installation of any affected oxygen cylinder having certain serial
numbers on any airplane, this proposed AD would include such a
prohibition.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 16 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
5 work-hours x $85 per hour = $425........................... $3,069 $3,494 $55,904
----------------------------------------------------------------------------------------------------------------
The FAA has included all known costs in its cost estimate.
According to the manufacturer, however, some or all of the costs of
this proposed 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
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.
