Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background The FAA issued an NPRM to amend 14 CFR part 39 by adding an AD that would apply to all MHI RJ Aviation ULC Model CL–600–2B19 (Regional Jet Series 100 & 440). The NPRM published in the Federal Register on February 25, PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 63971 2022 (87 FR 10752). The NPRM was prompted by AD CF–2021–32, dated September 17, 2021, issued by Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada (referred to after this as the MCAI). The MCAI states that an oxygenfed ground fire event was 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. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2022–0141. In the NPRM, the FAA proposed to 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. Actions Since the NPRM Was Issued Since the FAA issued the NPRM, an operator reported a fouling condition between the power feed wires for the stowage box light strip and an existing aluminum bracket in the mask stowage compartment of the entrance monument. MHI RJ determined that additional actions were needed to further address the unsafe condition. TCCA subsequently issued AD CF– 2021–32R1, dated July 25, 2022, to require an additional inspection for correct installation of the flexible lamp assembly; trimming and reidentifying a bracket; and for certain airplanes, an inspection for damage of the wire harness assembly; and applicable corrective actions to address the fouling condition. 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. Comments The FAA received comments from MHI RJ Aviation and Air Wisconsin. The following presents the comments received on the NPRM and the FAA’s response to each comment. Request To Incorporate Revised Service Information MHI RJ Aviation and Air Wisconsin requested that the FAA incorporate new E:\FR\FM\21OCP1.SGM 21OCP1 63972 Federal Register / Vol. 87, No. 203 / Friday, October 21, 2022 / Proposed Rules service information into this proposed AD. MHI RJ noted that when an operator performed the actions specified in the proposed AD, it resulted in an unforeseen new potential fouling condition with the existing bracket. MHI RJ stated that it had asked operators to not complete the actions until revised service information, including instructions to ensure clearance between the bracket and harness, was available. Air Wisconsin requested that the proposed AD be revised to include the new service information and additional work. The FAA agrees and has revised this proposed AD to refer to Service Bulletin 601R–35–022, Revision B, dated April 21, 2022, as the appropriate source of service information to accomplish the required actions. This service information includes additional work to address the potential fouling condition. Related Service Information Under 1 CFR Part 51 The FAA reviewed MHI RJ Service Bulletin 601R–35–022, Revision B, dated April 21, 2022. This service information specifies procedures for doing a 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 also specifies procedures for an inspection for correct installation of the flexible lamp assembly; trimming and reidentifying a bracket; and for certain airplanes, an inspection for damage of the wire harness assembly; and applicable corrective actions. Corrective actions include correcting flexible lamp assembly installations and repair. 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 and Requirements of This SNPRM 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, it has notified the FAA of the unsafe condition described in the MCAI and service information referenced above. The FAA is issuing this SNPRM after determining that the unsafe condition described previously is likely to exist or develop on other products of the same type design. Certain changes described above expand the scope of the NPRM. As a result, it is necessary to reopen the comment period to provide additional opportunity for the public to comment on this SNPRM. Proposed AD Requirements in This SNPRM This proposed AD would require accomplishing the actions specified in the service information described previously. 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: jspears on DSK121TN23PROD with PROPOSALS ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Up to 9 work-hours × $85 per hour = Up to $765 .......... Up to $115 ......................... Up to $880 ......................... Cost on U.S. operators Up to $358,160. Authority for This Rulemaking Regulatory Findings List of Subjects in 14 CFR Part 39 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. 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.

Background

    The FAA issued an NPRM to amend 14 CFR part 39 by adding an AD that 
would apply to all MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet 
Series 100 & 440). The NPRM published in the Federal Register on 
February 25, 2022 (87 FR 10752). The NPRM was prompted by AD CF-2021-
32, dated September 17, 2021, issued by Transport Canada Civil Aviation 
(TCCA), which is the aviation authority for Canada (referred to after 
this as the MCAI). The MCAI states that an oxygen-fed ground fire event 
was 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.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2022-0141.
    In the NPRM, the FAA proposed to 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.

Actions Since the NPRM Was Issued

    Since the FAA issued the NPRM, an operator reported a fouling 
condition between the power feed wires for the stowage box light strip 
and an existing aluminum bracket in the mask stowage compartment of the 
entrance monument. MHI RJ determined that additional actions were 
needed to further address the unsafe condition. TCCA subsequently 
issued AD CF-2021-32R1, dated July 25, 2022, to require an additional 
inspection for correct installation of the flexible lamp assembly; 
trimming and reidentifying a bracket; and for certain airplanes, an 
inspection for damage of the wire harness assembly; and applicable 
corrective actions to address the fouling condition. 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.

Comments

    The FAA received comments from MHI RJ Aviation and Air Wisconsin. 
The following presents the comments received on the NPRM and the FAA's 
response to each comment.

Request To Incorporate Revised Service Information

    MHI RJ Aviation and Air Wisconsin requested that the FAA 
incorporate new

[[Page 63972]]

service information into this proposed AD. MHI RJ noted that when an 
operator performed the actions specified in the proposed AD, it 
resulted in an unforeseen new potential fouling condition with the 
existing bracket. MHI RJ stated that it had asked operators to not 
complete the actions until revised service information, including 
instructions to ensure clearance between the bracket and harness, was 
available. Air Wisconsin requested that the proposed AD be revised to 
include the new service information and additional work.
    The FAA agrees and has revised this proposed AD to refer to Service 
Bulletin 601R-35-022, Revision B, dated April 21, 2022, as the 
appropriate source of service information to accomplish the required 
actions. This service information includes additional work to address 
the potential fouling condition.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed MHI RJ Service Bulletin 601R-35-022, Revision B, 
dated April 21, 2022. This service information specifies procedures for 
doing a 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 also specifies procedures for an inspection for 
correct installation of the flexible lamp assembly; trimming and 
reidentifying a bracket; and for certain airplanes, an inspection for 
damage of the wire harness assembly; and applicable corrective actions. 
Corrective actions include correcting flexible lamp assembly 
installations and repair.
    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 and Requirements of This SNPRM

    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, it 
has notified the FAA of the unsafe condition described in the MCAI and 
service information referenced above. The FAA is issuing this SNPRM 
after determining that the unsafe condition described previously is 
likely to exist or develop on other products of the same type design.
    Certain changes described above expand the scope of the NPRM. As a 
result, it is necessary to reopen the comment period to provide 
additional opportunity for the public to comment on this SNPRM.

Proposed AD Requirements in This SNPRM

    This proposed AD would require accomplishing the actions specified 
in the service information described previously.

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
----------------------------------------------------------------------------------------------------------------
              Labor cost                      Parts cost            Cost per product      Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 9 work-hours x $85 per hour =    Up to $115.............  Up to $880.............  Up to $358,160.
 Up to $765.
----------------------------------------------------------------------------------------------------------------

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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.
