SUPPLEMENTARY INFORMATION:
Discussion
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued TCCA AD CF-2021-17, dated April 28,
2021 (also referred to as the Mandatory Continuing Airworthiness
Information, or the MCAI), to correct an unsafe condition for certain
Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. You may
examine the MCAI in the AD docket on the internet at <a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching for and locating Docket No. FAA-2022-
0085.
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 BD-700-1A10 and BD-700-1A11 airplanes. The NPRM published
in the Federal Register on February 3, 2022 (87 FR 6082). The NPRM was
prompted by reports of oxygen leaks caused by cracked, brittle, or
broken oxygen hoses that were found during scheduled maintenance tests
of the airplane oxygen system. The NPRM proposed to require an
inspection of the oxygen hose assembly to determine if an affected part
number is installed, and replacement of affected oxygen hoses. For
certain airplanes, the NPRM proposed to allow repetitive testing of the
oxygen system until affected hoses are replaced. The NPRM also proposed
to prohibit installation of an affected oxygen hose. The FAA is issuing
this AD to address a leak in the oxygen line, which may result in
failure to provide oxygen to passengers and crew and result in an
oxygen enriched atmosphere creating a fire risk on the airplane. 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 comments
received on the NPRM and the FAA's response to each comment. Air Line
Pilots Association, International (ALPA), an individual commenter, and
Bombardier indicated their support for the NPRM.
Request To Revise the Conditions for the Aircraft Completion Center
Supplemental Type Certificate (STC) Date
Bombardier requested that the FAA revise the conditions for the
Aircraft Completion Center STC date. Bombardier stated that the use of
the date when the Aircraft Completion Center STC was issued as
specified in paragraphs (h)(1)(i), (h)(1)(ii) and (h)(3) of the
proposed AD, will, in some cases, be inconsistent with the instructions
given in the service bulletin. Bombardier commented that in cases where
multiple configurations are approved by the Aircraft Completion Center
STC, the date that the STC was issued is not necessarily indicative of
the age of the hoses and should not be used. Bombardier stated that,
for example, STC ST03088NY, was issued April 20, 2012, but has been
used since then to approve many serial-number-specific configurations.
Bombardier suggested that the date used to determine whether
operators may perform interim inspections and delay hose replacement be
based on one of the following conditions:
<bullet> Initial approval of the aircraft completion modification
was demonstrated by a serial number specific to the STC and the date
the STC was issued; or
<bullet> Initial approval of the aircraft completion modification
was demonstrated on an STC that approves multiple configurations by the
initial approval date of the serial number specific configuration that
correlates to the date STC was added to the approved configuration
list.
Bombardier commented that the suggestion is consistent with the
service information provided in Bombardier Advisory Wire AW700-35-0794,
which includes an explanation of how to find the ``Aircraft Completion
STC date'' (expression used in the associated service information), for
cases where Bombardier is the STC holder.
The FAA disagrees with the commenter's implication that the ability
to delay hose replacement is determined by the date of the STC. The
date as given relative to an STC is only for the optional interim
testing and if all conditions are met; whether an operator may delay
replacement is determined solely based on serial numbers. If an STC is
installed with the referenced hoses, the serial numbers can be checked
on the hoses. 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:
<bullet> Are consistent with the intent that was proposed in the
NPRM for addressing the unsafe condition; and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM.
Related Service Information Under 1 CFR Part 51
Bombardier has issued the following service information.
<bullet> Bombardier Service Bulletin 700-1A11-35-014, Revision 01,
dated February 12, 2021.
<bullet> Bombardier Service Bulletin 700-35-015, Revision 01, dated
February 12, 2021.
<bullet> Bombardier Service Bulletin 700-35-5005, Revision 01,
dated February 12, 2021.
[[Page 35887]]
<bullet> Bombardier Service Bulletin 700-35-6005, Revision 01,
dated February 12, 2021.
<bullet> Bombardier Service Bulletin 700-35-6501, Revision 01,
dated February 12, 2021.
This service information describes procedures for doing an
inspection of the oxygen hose assembly installations to determine if a
part number within the series O2C20T1 is installed, and replacing the
oxygen hose if necessary. For certain airplanes, the service
information specifies optional repetitive testing of the oxygen system
that would allow for delay of the replacement. These documents are
distinct since they apply to different airplane serial numbers.
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.
Costs of Compliance
The FAA estimates that this AD will affect 409 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Labor cost Parts cost Cost per product Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 36 work-hours x $85 per hour = Up $0 Up to $3,060.............. Up to $1,251,540.
to $3,060.
----------------------------------------------------------------------------------------------------------------
Estimated Costs for Optional Actions
------------------------------------------------------------------------
Labor cost Parts cost Cost per product
------------------------------------------------------------------------
Up to 25 work-hours x $85 per Up to $125........ Up to $2,250.
hour = Up to $2,125.
------------------------------------------------------------------------
The FAA has included all known costs in its cost estimate.
According to the manufacturer, however, some or all of the costs of
this 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
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.
