Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for all MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This proposed AD was prompted by a report of an oxygen-fed ground fire event potentially caused by electrical arcing from a faulty surround light wire on the third crew member's (observer) oxygen mask. This proposed AD would require an inspection for discrepancies of the observer's oxygen mask stowage box and storage compartment, oxygen hose connections and routing, and the associated electrical harness, and corrective actions if necessary; and modifying the oxygen mask flexible lamp harness, mounting plate, and compartment panel, including rerouting the electrical harness and applying protective sealant. The FAA is proposing this AD to address the unsafe condition on these products.

AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for all MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 100
& 440) airplanes. This proposed AD was prompted by a report of an
oxygen-fed ground fire event potentially caused by electrical arcing
from a faulty surround light wire on the third crew member's (observer)
oxygen mask. This proposed AD would require an inspection for
discrepancies of the observer's oxygen mask stowage box and storage
compartment, oxygen hose connections and routing, and the associated
electrical harness, and corrective actions if necessary; and modifying
the oxygen mask flexible lamp harness, mounting plate, and compartment
panel, including rerouting the electrical harness and applying
protective sealant. 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 April 11,
2022.

you actually treat as private, and that is relevant or responsive to
this NPRM, it is important that you clearly designate the submitted
comments as CBI. Please mark each page of your submission containing
CBI as ``PROPIN.'' The FAA will treat such marked submissions as
confidential under the FOIA, and they will not be placed in the public

Background
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued TCCA AD CF-2021-32, dated September
17, 2021 (also referred to after this as the Mandatory Continuing
Airworthiness Information, or the MCAI), to correct an unsafe condition
for all MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 100
& 440) airplanes. You may examine the MCAI in the AD docket at <a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching for and locating Docket No. FAA-2022-
0141.
This proposed AD was prompted by a report of an oxygen-fed ground
fire event potentially caused by electrical arcing from a faulty
surround light wire on the third crew member's (observer) oxygen mask.
An investigation determined that the oxygen supply hose connecting to
the rear of the observer oxygen mask box assembly could be subject to
chafing damage. The FAA is proposing this AD to address possible damage
to the observer oxygen mask supply hoses and a potential for an oxygen-
fed fire in the vicinity of the observer oxygen mask storage
compartment. See the MCAI for additional background information.
Related Service Information Under 1 CFR Part 51
MHI RJ has issued Service Bulletin 601R-35-022, Revision A, dated
October 12, 2021. This service information describes procedures for
doing an general visual inspection for discrepancies (including elbow
fitting clocking (rotation), sealing tape installed in a certain
location, wire damage (e.g., cuts, nicks, kinks, insulation damage)) of
the observer's oxygen mask stowage box and storage compartment, the
observer's mask oxygen hose connections, the hose routing, and the
associated electrical harness, and applicable corrective actions; and
modifying the oxygen mask flexible lamp harness, mounting plate, and
compartment panel, including rerouting the electrical harness and
applying protective sealant. Corrective actions include re-positioning
the elbow fitting, removing sealing tape, and repairing wiring. 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.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 407 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
----------------------------------------------------------------------------------------------------------------
9 Work-hours x $85 per hour = up to $765..................... $115 $880 $358,160
----------------------------------------------------------------------------------------------------------------

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.
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:
